Extra 26.1

**Extra 26.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* Yamada and Ichikawa are at a convenience store called "Fairy Mart." She asks him if he knows a trick to make frozen ice cream softer so you can eat it sooner, and he replies that he does not. She then begins furiously rubbing a small container between her hands, which he calls primitive, but concludes that it works. She then places her cold hand on his face, saying he's warm, and he runs out of the store, but has to go back in because he forgot he needed pencil lead.

* Another page is the rough draft of the panels of Ichikawa and Yamada in the elevator.

* During a class-room change, Ichikawa is the last to leave, but as he begins exiting, Yamada comes back in, saying she forgot something. She grabs a pile of books, and he asks if she forgot *everything* instead. She follows him out of the room, and he stops at the bathroom, so she takes his things, and he thanks her. When he exits, she is messing around with some of her friends from another class, so he hides, not wanting to associate himself with her. They ask her why she's standing around in front of the bathrooms, and she replies that she's waiting on a friend. At this proclamation, Ichikawa brightens up, amazed that she considers him a friend. She makes an excuse for her friends as to why she can't follow them, and he assumes it's to scare them off so she doesn't have to be seen with him. When they begin walking to the class, he reconsiders that she may just want to walk with him.

## Trivia

* "Fairy Mart" is a parody of Japanese convenience store "Family Mart."

* Given Yamada's previous interactions, it is more likely that she simply wants more alone time with him.
Extra 104.1

**Extra 104.1** is an Extra in Boku no Kokoro no Yabai Yatsu.

## Summary

* In her room, Yamada is turning all of the dolls on her bed around so that they face the wall. Ichikawa comes in, and asks her what she's doing. She says that she watched Toy Story on television yesterday, and he says that he's seen it. He says that Toy Story 2 is the better one, but they don't put it on tv very often, and she agrees as he takes a seat on her bed. He asks "what about it?" as she moves closer to him and begins fidgeting.
Chapter 66: I Was Thrown

**I Was Thrown** is the sixty-sixth Chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

Ichikawa is putting on a judo gi, having picked it over creative dancing along with most of the boys, excluding Hara and Yamada, who are with them. Yamada tells Hara that she's bad at dancing, and is glad that she's there with them. Kanzaki asks where Adachi is, and Oota awkwardly explains that he chose dance-class, with a cutaway panel showing Adachi looking for Yamada while Moe and Chi judge him with scornful expressions. Ichikawa concludes that he must have chosen that class with bad intentions.

Yamada looks upset, fidgeting with her gi, and Hara asks what is wrong. Yamada says that her outfit stinks, and Hara tries to downplay it, but takes a sniff, and coughs in reaction. Ichikawa considers offering to trade with her, but finds it too creepy. Maeda tells everyone to split into groups of two for a kumite, and Ichikawa is surprised to realize that he and Yamada are left as the only two remaining picks. Before he can process this, however, Maeda suddenly grabs him and demonstrates a slam onto the mat. After recovering, he lightly taps Yamada's leg with his foot to initiate a fight, and she plays along, grabbing him by the jersey. He wonders if it's okay due to them being in different ranks, but she says they weigh around the same, so it's fine. The two tussle, and she complains again about the stench, which he can't argue against, but he offers that that's the reason she won't pair up with anyone else, pinning her to the wall. She becomes flustered, and suddenly kicks his legs out from under him, and he again finds himself on the mat as she claims payback.

Back in their normal clothes, Yamada, Ichikawa, Kanzaki, and Hara are walking back to class. Kanzaki brings up how Ichikawa got along pretty well with Yamada, and he wonders if he saw them pair up. He tries to explain about her being concerned about the smell, which causes her to again smell her normal jersey for residual stench, but Kanzaki misunderstands, and grabs his hand to shake it. He says that Ichikawa understands that stinky girls are great, leaving both him and Yamada upset.
Lucifer Nigorikawa

Nigorikawa as he appears in Chapter 76 of the manga.

**"Lucifer" Nigorikawa** is a figment of Ichikawa's imagination in *Boku no Kokoro no Yabai Yatsu.*

Not quite a real "character" per se, Nigorikawa is an imaginary figure that Ichikawa conjures up to help himself deal with his emotional shortcomings. He is largely based off of Nigorikawa-kun, the male lead of Yamada's favorite shoujo manga, *Your Color's Octave*. The "Lucifer" moniker and the associated black wings he sometimes sprouts are additions from Ichikawa's chuunibyou delusions.

## Appearance

Nigorikawa looks identical to the fictional Nigorikawa in Yamada's favorite manga, other than the aforementioned black wings. He is a tall, "pretty boy" protagonist common in shoujo manga. He has black, short-cut hair and striking features.

## Personality

His only real personality trait is acting as a kind of guide towards self-improvement for Ichikawa, especially in regards to his relationship with Yamada. He pushes him to interact with her more directly and not to doubt himself in regards to her affections.
Yamada's Apartment

A diagram of Yamada's Apartment.

**Yamada's Apartment** is a location in *Boku no Kokoro no Yabai Yatsu*. It is part of an apartment high-rise where The Yamada Family lives.

The apartment is on the sixteenth story, and is apartment seven on that floor.

It is composed of a large living area with a kitchen, lounge area, and a laundry room which leads into the bathroom. There is a sizeable study room, and both Yamada's room and her parents' room are in the back. A large balcony overlooks the street below.

## Trivia

According to Chapter 11, the high-rise was once the site of a farm field approximately 80 years ago.

Yamada's Apartment is about one kilometer (.62 Miles) from Ichikawa's House.

The real-world inspiration for Yamada's apartment is The Grand Mid Towers Omiya here, in the Saitama Ward.
Extra 38.1

**Extra 38.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* Ichikawa is rubbing his hands together, talking about how cold it is. Yamada says she'll give him a warmer, and turns around, pulling it from underneath her shirt/skirt. When she hands him the warmer, he touches it, but immediately realizes there is fiber attached, and connects that she must have had it on her panties. He immediately rejects the warmer, lying and claiming he is no longer cold. She asks if he's cold anywhere else, and he denies it, but she claps a hand on his cheek to feel, saying he's cold. She then claps her other hand on his other cheek, along with the warmer, leaving him unable to speak, but she starts laughing, comparing the warmer to a bandage.

* Yamada is talking to Ichikawa about a premonition she is having, where one week from today, he will be laughing and surrounded by red. He imagines it as him going on a murder spree, wielding his knife amongst a room full of bodies, and chuckling evilly. He begins thinking of what the day will be, and the panel cuts to Yamada looking happily, showing it to be the 17th of December.

* A color page is Yamada dressed up as Santa pointing her finger at her mouth as though to say "shh."

* Yamada and Ichikawa are walking home from school. She has a bit of leaf and berries from the Christmas cake they had earlier today tucked in her mouth, and he declares that Halloween and Christmas are things for children. At first she seems upset, but she takes the decoration and puts it behind his ear, saying it's a good thing they're both children. In his head, he agrees, though he's unnerved by her touching him.

* A color page with two variations is Yamada in a hot spring, holding a snowman with a leaf over the head, looking like Ichikawa. One has more steam than the other.

* Another bonus page is of all the boys thinking the word "Nipples."

* Yet another color page is Yamada looking at her phone excitedly, while Chi and Serina are passed out around her at her house. It is New Year's, and the year has just switched over from 2019 to 2020.

* A color page is Yamada and Ichikawa in kimonos. They are apparently at Disney Land Tokyo, as they are wearing Mickey Mouse ears.

* Another few pages is a fortune game using characters from Mitsudomoe, with Yamada winning either the "Super Luck" or "Super Ero" fortune.

* The final art is Yamada and Ichikawa praying at a shrine in their kimonos. They have on Mickey and Minnie Mouse ears, in reference to the Year of the Mouse.

## Trivia

* While certainly not a canonical event, Yamada saying he will be surrounded by red on Christmas Eve is followed up by the image of her on his bed, dressed as Santa, implying she's the red he will be surrounded by. This has a canonical explanation during the actual Christmas Date, though, so is likely just innuendo.

* The page of Yamada with Chi and Serina is apparently canon, taking place in Chapter 53. Yamada and Serina are wearing the same outfits, and Yamada is the only one awake, and, of course, it takes place on New Year's. Moe is not there because she is currently walking with Ichikawa to Serina's place.
Extra 126.1

**Extra 126.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* A color image of Yamada in a green bunny outfit for Bunny Day, an internet holiday where people draw their favorite characters in bunny costumes.

## Trivia

* Yamada's bunny outfit is a close replica to Asuna's from Blue Archive, which is also the one she said she implied she would cosplay in Extra 107.1.
Chapter 131: I Didn't Bring It

**I Didn't Bring It** is the one-hundred-and-thirty-first Chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

The girls are having fun splashing in the ocean, while Ichikawa sits on a blanket on the beach, worrying about the condom he picked up. He believes that, having saw him pick it up out of the sand, that Yamada, Moe, and Serina all know he has it, and believe that it must be his. He rolls over on his side, believing that this is the worst outcome possible, and considers other ways he could have reacted, while Lucifer Nigorikawa manifests and tells him that it's all fine if Yamada was the one who actually brought it. He proposes that, if it were, then they could just *do it,* though Ichikawa insists that there are many steps to take before that. As he considers the possibility, Yamada comes over to sit beside him, and he becomes determined to keep the mood light. He turns to her and casually asks, if they have time today, that he wants to talk with her alone, which immediately causes her to panic and run off when the other girls call her back to the ocean. Nigorikawa demands to know why he took such a serious tone, and he begins trying to read into her reaction, wondering if she took his response to mean he wanted to try tonight.

Later, everyone walks back to the retreat house, carrying groceries after shopping. The girls prepare a meal while Ichikawa takes a bath, scrubbing furiously, but insisting that nothing like in his imagination will happen. They all sit down for a meal, and Moe comments that it might be the first time she's ever cooked for a boy, leaving Yamada angry and the air tense. Serina insists he barely counts, and Chi asks why Yamada seems less cheerful than she did this morning, saying she should clear up anything that's worrying them. Serina insists it's just fatigue from the summer heat, and Ichikawa agrees that it was pretty rough out today. They lock eyes and react with surprise while he considers why she's covering for Yamada, even considering if she may have been the one who brought the condom for a "one-time summer experience."

Outside, by the hammock, Ichikawa wonders if he is being tortured while the girls' swimsuits dry on a nearby mobile clothes line. Serina opens the door leading inside and walks out, peering out over the dividing wall, and asks if he thought she was Yamada, which he denies. He wonders what it is that she wants, and at that moment she asks about the condom, just as Yamada herself walks through the door.
Extra 65.1

**Extra 65.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* Yamada and Ichikawa are playing with a pair of cats.
* A continuation of the previous Chapter, Ichikawa talks about how much weaker his right arm has become. She wants to see his grip, and he suddenly grabs her hand and squeezes. She panics, clarifying she meant for him to just make a fist, but neither of them breaks the hold as they awkwardly change topics to 5th Period Math.
* An image from the first-person perspective of Ichikawa, where he is staring at Yamada, who is looking forward. She notices he is looking her way, and fidgets, switching her target back and forth, before beaming a bit smile, and looking away, flustered.
* Outside, Yamada is sighing, and Ichikawa asks what is wrong. She brings up how she's concerned how she'll get married late, because of a superstition about Hinamatsuri dolls if you keep them up for too late after the festival, which she insisted upon as a child. He comments about how it's an outdated delusion based on Showa-Era values, and marriage can be optional in today's world, which she disapproves of with a frown. He considers whether Yamada would want to get married in the future, but because he doesn't see himself in that scenario, doesn't like to think about it. He offers that if she can't become a wife, someone could come over and become her husband. She looks at him excitedly, asking if he will, but he reacts with confusion. She looks away, blushing, saying it's getting hotter and hotter.
* Paralleling the earlier page, a first-person perspective of Yamada talking with her friends, but she notices Ichikawa looking at her from across the room. He initially breaks eye contact, and goes back to his book, but tries to play it cool at the end by looking back and offering a sly smile.
* Two images of Elementary School graduation, one for Ichikawa and another for Yamada. Ichikawa's is him dressed up with Takano and Kinoshita. Chi is in the background, alongside Hanzawa and another girl. Moe can be seen with her back turned. Yamada's is her posing with two friends in kimonos. Rin Kanaoya is in the background, mostly obscured by the left girl, and next to her is Serina, who had dyed blonde hair at the time. The lighter-haired girl to her right is likely the same girl that calls her out to the hallway in Chapter 58. The three guys peering in from the back are the same ones who tried to intimidate Ichikawa and his friends in Extra 57.1.

## Trivia

The comment about someone becoming Yamada's husband doesn't translate well in English. Essentially, the idea is the difference in a man joining the woman's family and taking her name, vs. the traditional way, in order to keep the name alive in families with no sons.
Yoshida Serina

* Anime
* Manga

**Yoshida Serina** (吉よし田だ   芹せり那な, *Yoshida Serina*) is a secondary character in Boku no Kokoro no Yabai Yatsu.

She is one of the girls in Yamada's friend circle. Attentive and sociable, she sometimes helps push Yamada and Ichikawa's relationship behind the scenes.

## Appearance

Serina often has her light-brown hair up in a ponytail. She is the second tallest member of her group, with Yamada only being about half-a-head taller. She tends to wear more "street" style clothing when out on her own, and may be something of a delinquent.

## Personality

Serina is often depicted as the most mature and skeptical amongst her friends, and also the most attentive. She recognizes that Ichikawa had been to Yamada's house before they were all invited to make chocolate based off him pushing the elevator buttons without being prompted and heading for the restroom without direction, both of which went totally over Moe's head. She appears to be the one that recommends the wallet chain to Yamada as a gift for Ichi, as she checks it out with approval once he is wearing it. She also seems to like "tough" boys and yankee types, though she sometimes acts as though she's above things like romance.

## Etymology

* **Yoshida** means "lucky, good" (吉) (**yoshi**) and "field, rice paddy" (田) (**ta**/**da**).
* **Serina** means "celery" (芹) (**seri**) and "what?" (那) (**na**).

## Trivia

* She is in the school dance club.
* She was in same Class 4 with Yamada in primary school.
Extra 119.1

**Extra 119.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* Five different images of Yamada sporting her blonde hair in one color picture. First image she is in her pink dress from Chapter 116, second she is in a green hoodie and shorts while yelling "Kyoutarou," third she is shirtless and washing her face, forth she is in her school uniform and eating a sucker, and finally she is in her gym clothes and sweating.
* An image advertising Episode 5 of the anime, featuring Adachi and Moe. Adachi is looking back at the camera, seeming angry, while Moe has her arms crossed, looking smug.
* A relationship timeline chart, showing what Yamada and Ichikawa thought about one another from the beginning of the series to now, as well as height. Yamada only grows point-one centimeter, from 171.9 to 172cm. Her opinion of Ichikawa goes: classmate > funny person > interesting > I like him > my boyfriend. Ichikawa grows six centimeters, from 152 to 158cm. His opinion of Yamada goes: I want to kill her > I like her > my girlfriend.
Extra 124.1

**Extra 124.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* An image of Yamada in three different swimsuits. One is a purple topped two-piece with white bottoms. Second is a one-piece white outfit, and she is holding a pink inner-tube. Third is another two-piece, all white, with frills, and she is holding an ice cream and desert drink.
* Ichikawa is trying on the various temporary tattoos he mentioned in the previous Chapter. He has one which is a thorned rose on his forearm, a second is a fanged mouth which he can put on his hand to mimic his real mouth, and third is an Eastern-style dragon emblazoned across his face. Yamada reacts with unwanted hilarity at his pictures, smacking the table and calling him a funny guy, while he looks at her reaction with embarrassment.

## Trivia

Ichikawa's sports-style jersey in the tattoo Extra is labeled with "Ev(e)rybody 564." Translated phonetically into Japanese this becomes "Everybody Goroshi," or "Kill Everybody."
Extra 57.1

**Extra 57.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* Ichikawa is napping at his desk, and his eyes slowly open, focusing on Yamada's chest as she bends down to watch his sleeping face. He jumps up and she reels back as they both yell out "Sorry!" to each other, but act with confusion as to what the other is apologizing for.
* Yamada is asleep with a book against her chest.
* A promotional image in collaboration with *Ooki Kouhai Wa Suki Desu Ka?* featuring Yamada and Oomori from that manga.
* Yamada waking up in the morning with bed-hair and drool leaving her mouth.
* Yamada is nodding off in the library, and is about to break the pocky in her hand, so Ichikawa grabs her wrist to stop that. She snaps awake and misinterprets his actions, putting the pocky in his mouth instead. She holds it in his mouth all the way to the base, eventually tapping her finger to his lips.
* Ichikawa is with Kinoshita and Takano in Elementary School, and each have bought packs from a trading card game to play with at the park. A group of kids from Migi Elementary are making a ruckus while playing soccer, and their stares prompt them to come up and threaten them. They say they're in sixth grade, asking what grade Ichikawa and Co. are, to which Kinoshita lies and says they're in the same grade. They mess with their cards, trying to start a fight, and one of the kids grabs Ichikawa when he smarts off about the rarity of one of the cards. The bullying boys become flustered when a group of girls (one of them being Yamada) walk by, though, and they use it as an excuse to run off. Once safely away, Takano offers a card to Ichikawa for standing up for him. They walk past the same group of girls, and Ichikawa stops in his tracks, commenting on her as being huge. Back at the present, Ichikawa looks at the card that he still has, and thinks back to that girl.
* A post-script from Norio Sakurai for the Volume 4 release. Yamada is standing behind the light pole during the events of Chapter 48, looking flustered and unsure of what to do as Ichikawa walks off. This is moments before she does her "Santa Yamada" bit.
Extra 79.1

**Extra 79.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* Likely following the events of the beach excursion, Yamada and Ichikawa, having been late to getting a bus, are staying overnight in some building. They are lying on two futons on the ground, and Yamada gets up, peers over Ichikawa's face as he tightly closes his eyes. She then goes back to her futon, and he put a quizzical look on his face. Later, Ichikawa gets up from his futon, and Yamada, still awake, looks around, but senses that he's no longer there and looks around for him. He has decided to lay down in the bed in the closet, and when she calls out, he slides open the door slightly so she can see him, not wanting to bring attention to the fact that he is awake. She sees him, and walks over surprised, then pats his head as he tries to act asleep.
* Yamada is wearing a negligee and Ichikawa is wearing a worker's outfit. The two are on a bed, and he is feeding her a cake for her birthday on September 10th.

## Trivia

The calendar on the wall in the background while Yamada searches for Ichikawa shows an "8" for August, with the Summer retreat in-canon happening on the 13th of August, meaning Norio had it planned out to the month when this event would happen in the chapters proper.
Chapter 20: I Defended Her

**I Defended Her** is the twentieth Chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

Maeda is addressing the class, telling them that various wrappers and bags from snacks were found in one of the trash cans on the first floor, near the library. Ichikawa looks over at Yamada, the obvious culprit, as she is messing with her eraser, and Maeda calls her out personally. She replies that she hasn't thrown anything away in the garbage, so he must be mistaken, to which he says that she should come to the staff room after class.

Later, Ichikawa is worried that if she gets in trouble for snacks, that she'll have to stop coming to the library, ruining their time together. He goes to the staff room and peers inside, seeing Maeda, but no Yamada, because she is presently behind him, which gives him a shock when he turns around. She asks if he has something to do there, and he meekly says that he was just passing by. With a grin, she asks him to accompany her, because she's scared. He tries to protest that he has nothing to do with the situation, but when she softly asks him "You won't?" he shakily follows her in, putting her in high spirits. Maeda asks why Ichikawa is there, and he makes up an excuse about this being an inspection, to oversee Yamada's interrogation. Maeda hits his desk, and tells Yamada that she isn't supposed to bring snacks to school, to which she asks why he thinks she has. Ichikawa shakily affirms that she hasn't admitted to anything, surprising Maeda that he'd speak out so much. He tries to reason out that she had to have based off her prior answer about not throwing anything away in the garbage, but Ichikawa reasons through vague logic that that is just "Miss Yamada's" way of taking everything at face value. Maeda considers the kind of person she is, realizing that Ichikawa might be right, and momentarily losing his ability to refute the shaky logic. Ichikawa begins walking off with Yamada in tow, thinking he has won handily, but Maeda stops him and, to his surprise, says that he's amazed he talked this much, and that it made him really happy. He slaps Ichikawa playfully on the back, which he finds annoying, and the two students leave the room.

Outside, Yamada thanks Ichikawa for his contribution, though she says she wasn't completely satisfied with how he went about it. He says it was just sophistry that made it work. She offers him "candy," with two options in her hand, an actual candy, and the eraser she was messing with earlier. Uninterested in candy, he chooses the eraser, which causes her to call him a kid, to his annoyance. She runs off ahead of him, but turns back, telling him that "just Yamada" is fine when referring to her, to his shock.

* A bonus page is Yamada explaining that she isn't just messing around with her eraser, and in fact was erasing a large mistake.

## Trivia

* Maeda takes an interest in helping Ichikawa out following this chapter, and recognizes his relationship with Yamada growing. This will later cause him to recommend him for the graduation speech, among other things.
Extra 86.1

**Extra 86.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* Following the events of the previous Chapter, Yamada and Ichikawa are still alone together in the karaoke room. He brings up how this is the first time he's been to karaoke, and Yamada reacts with surprise, teasing him. She then says that she is too embarrassed to sing, and doesn't come very often. He mentions how this may then be the last time he ever comes, because he doubts he'll ever be hanging out with anyone but her. They both get flustered at his proclamation.
* Ichikawa is casually carrying a trash back by having it slung behind his back, trying to look cool. Yamada and the school nurse notice him, with Yamada saying he looks like Santa, but the nurse saying he looks like a thief. The nurse then walks off, but Yamada offers that they do Santa practice. Yamada then goes back into the nurse's office and pretend-sleeps on the bed. Ichikawa pulls back the curtain and peers in, looking creepy, and looming over her, which he considers a form of assault. He looks through his trash bag, considering giving some of it to her, but considers it a bad idea. She fake-mumbles in her sleep, saying she wants wagyu beef and rice. He recommends that she join a tax reward program to earn some. She then bolts awake, saying he woke her up, and that he has lost the game, which he claims is ridiculous. He asks why he's even playing this game, because he doesn't plan on being Santa. Yamada lays back down and says that maybe one day he will, to which he reacts with confusion. She nudges him with her knee and says that when that happens, she'll help as well. He asks if she's a reindeer.
* A color image of Yamada in a Christmas sweater, which there is an icon of Ichikawa dressed up in Christmas theme, and short shorts.

## Trivia

Yamada appears to be implying that they are practicing Santa for their future children.
Extra 87.1

* Yamada and Ichikawa dressed up as tigers for The Year of the Tiger. Ichikawa is in a onesie, while Yamada is in a miniskirt and bikini top.

Extra 61.1

**Extra 61.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* A collection of BokuYaba LINE stickers.
* Yamada and Ichikawa are meeting up at McDenalds. He appears overdressed in several layers of clothing, and a hat. She suddenly starts taking off his jacket, and looking him over, which he concludes is a fashion check. She sulks, which he takes as being him failing the check, and he frets about it. She motions to her ears, and points out the skull piercings she has in. He doesn't understand, and gets up to wash his hands, she suddenly gets excited, pulling up his shirt to reveal the skull pattern on his back pants pocket, happy to have found it. They talk about the differences between the two skulls.
* Baby Ichikawa wearing a pair of light-up Yamada pajamas.
Chapter 8: I Started Boiling

**I Started Boiling** is the eighth chapter of *Boku no Kokoro no Yabai Yatsu*.

Yamada is fanning herself with a slip of paper to cool off on a hot day, but is continuously smacking herself in the face while doing so. Chi grabs the paper from her, telling her to gain a sense of distance. Yamada proposes Chi fan her, which ultimately results in the two, along with Moe and Serina, creating a circle of fanning. Chi now finds herself being smacked with Yamada's fan, and she yells at her for it, resulting in Moe telling her to knock off the skit.

Ichikawa is watching all of this from a distance, while also using his own fan to keep cool. Adachi then talks about seeing one of the girl's bras through their shirts, after Yamada mentions sweating through hers. Ichikawa, who was thinking the same thing, reacts shocked, wondering if he can read his mind. When Adachi announces his plan to go up to the girls to get a peek, Ichikawa tries to tell him not to do so with his mind. When this doesn't work, he drops his knife on the floor as Adachi walks by, wasting his time long enough for the girls to leave for the staff room, which they believe will be cooler.

Later, in the library, Ichikawa is reading a book while still fanning himself. Yamada notices him and asks to use his fan, to which he awkwardly agrees. As she uses it, she compliments the smell, and when Ichikawa is doubtful, she tells him to lean over and smell for himself. He does so, and catches a glimpse at the school swimsuit she is wearing underneath her outer clothes, to prevent her underwear from being shown. She hands back his fan, and he immediately heads for the bathroom.

* A bonus page is Moe and Serina asking Yamada about her habit of wearing a school swimsuit to class in the 4th grade.

* A second bonus page is a comparison shot of Yamada from 2009 (approximately 4 years old) and 2018 (current, 13 years old) with her dog, Wantaro.

## Trivia

* First appearance of Wantaro. Assuming he was a recently weaned puppy in the first half of the image, this would put him at 9 years old in this chapter.

* The second bonus page seems to imply that the series takes place in 2018 along with the series' publication, but a later chapter shows a calendar in 2019, so this image must be of Yamada a year ago.

* Ichikawa Implied Masturbation Count: 2.

## Lyrics

* Japanese Lyrics (ANIME)
* Japanese Lyrics (FULL)
* English Lyrics

Dusk is a time when you can't tell how close you're getting.

You're lost in a maze, and you don't know where the exit is.

The abnormal has become the normal.

It's against the rules. Wait, wait, wait.

It doesn't matter. I can't be honest with myself.

Maybe I want to stay like this forever.

That feeling has melted away.

We've been searching... for our hearts to match.

We were exchanging coherent lines.

I wanted to touch you, but the heat of your hands reached my heart.

I was growing up so tall. I saw you growing up.

I want to know you. I wanted to get closer, and a dream wasn't enough, and my heart ached...

I want to get to know you.

I'm starting to see that I'm becoming more self-aware.

I'm starting to understand. The sun is shining on the maze I'm lost in.

I'm wondering what I want to do, how I want to feel.

I was picking up the pieces of my memory.

I can't stay like this forever.

I moved the hands of my watch forward.

We were looking for... a matching heart.

We were exchanging coherent lines.

The heat from our overlapping hands reached our hearts.

We were running away, with the glowing sky in the background.

I want to know, even beyond this.

I wanted to get closer, a dream wasn't enough, my heart ached.

I wanted to get closer, I wanted to be closer, I wanted to see your heart.

I wanted to put it into words.
## Video (Anime)

The music video is largely composed of a variety of model shots and photos between Yamada and her friends.

The video opens on a spinning flower held in the middle of various images of the school and around town - the school gate, Ichikawa's house, the awning leading into the school, and the library. It cuts to Yamada opening her eyes, then an image of her in a pink dress surrounded by other pink things, a donut, lollipops, a telephone, all on a pink mattress. The next image is purple themed, with Yamada wearing a beret and a shirt amidst purple curtains. The next image is brown-and-orange themed, with Yamada wearing a hat and a vest, standing against a yellow wall, with various pictures and a record stuck on it. Next is Yamada in a white dress and yellow hat amidst a blue sky.

The next images are more casual, starting with Yamada stuffing her face with convenience store buns, while Moe shows Serina something on her phone in the background. Next, Yamada is sitting on Chi's lap, with Yamada taking a selfie with a cat filter on, and sparkles and hearts surrounding them. Following that is Yamada running down the halls of the school, spilling candy from her pockets and leaving a trail. The last photo is of Yamada sitting with her arm propped up against a desk, looking at the camera. The final image is of Yamada staring forward before her face bursts into excitement, and a flower turns into a heart.
Extra 50.1

**Extra 50.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* A text conversation between Yamada and Ichikawa, where he tells her that the only things interesting at his grandma's house is snow and a pet cat. She grabs Wantarou and sends a picture of them to him, with her being in revealing loungewear, asking him to send one, too. Confused, he sends a picture of himself in a baggie t-shirt, and she responds asking where the cat is. The last panel is Ichikawa screaming into the kotatsu, while his grandmother and her cat look on confused.

* Yamada and Ichikawa are eating Papico, and she says the only downside about them is that they leave your hands too cold. He pulls out a handkerchief, and wraps it around his, and she childishly demands it, but he says he's not done eating. She grabs one end of the cloth and wraps her papico in it, and the two continue sucking on their treats. He thinks on how, if they weren't in a spot where nobody could see them, he would have died from embarrassment. Another page is a close-up of their faces next to each other, to show the perspective the two have while eating.

## Trivia

* Kyoutarou misunderstands Yamada's request for a picture completely. When he brings up interesting things at his grandma's house, he mentions a cat, and she wants to see a picture of it, offering a picture of her and her dog in trade. He ignores the dog and only sees her in her revealing housewear, and assumes she wants a sexy picture instead. The image of him with his shirt down low and looking very uncomfortable can then be taken as his best attempt at looking seductive. When she asks where the cat is, he realizes his mistake, and screams into the kotatsu in response to his own stupidity.

* The associated tweet from Sakurai Norio states that the two of them deleted those pictures after the misunderstanding.

* The papico extra is obviously a play off of the idea of Yamada and Ichikawa making out, as the two are face-to-face making sucking noises.
With Her Eyes Half-Open

*With Her Eyes Half-Open!* is a 2015 one-shot gag manga starring Kobayashi Chihiro and Hanzawa Yurine.

A prequel to *BokuYaba* proper, the one-shot is a simple gag manga where Chii attempts to befriend her new classmate, Hanzawa.

## Summary

Chihiro Kobayashi realizes that her classmate Yurine Hanzawa seems to be able to read while in a half-sleep trance, but is actually zoning out when her eyes are at attention. After a confrontation with another girl in their class, she seemingly confirms her theory when she notices the zipper is undone on her shorts.

## Trivia

* This one-shot is the earliest point in *BokuYaba's* canon, though it has relatively little to do with the plot of the manga proper, and is just a strange interaction between two secondary characters.
* This is the first appearance of Kobayashi Chihiro and Hanzawa Yurine.
Extra 115.1

**Extra 115.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* One page is a celebration of three-million volumes of the series sold. Yamada is doing double-peace-signs, while Ichikawa acts smug, saying it was "an obvious outcome," and her asking what kind of character he's trying to be. Below this, three different angles from Chapter 106, Page 9, where Kana calls Adachi a brat are shown.
Chapter 30: I Melted

**I Melted** is the thirtieth Chapter of *Boku no Kokoro no Yabai Yatsu*. It is the final Chapter of Volume 2.

## Summary

Ichikawa enters into the library to see a shocked Yamada staring at the bulletin board. He begins to ask what is wrong, but reads the message, simply stating that "Food and drinks are prohibited in the library." They go over the new poster and when it got there, and Ichikawa goes over a list of people who could have snitched. Yamada denies any of them have anything to do with it, and they ultimately decide to ask the library committee directly. They confront the librarian, who brings up a wrapper from a honey lozenge as proof, since Yamada knows she disposes of her snack wrappers discreetly.

Back at the library, Ichikawa worries that this may be the last day that Yamada meets with him there. However, she simply opens her bag and pulls out a new package of chocolates, to his surprise. She explains that she always knew it was against the rules, and the poster changes nothing. At that moment, Ichikawa notices someone coming out from behind his usual bookshelf, and Yamada, oblivious, continues eating the candy, even as she turns the corner, revealing herself to be the librarian. In a swift motion, Ichikawa drops his book, and quickly leans across the table to grab her chocolate-wielding hand, telling himself he can't believe how much he likes her. Yamada, taking in the various stimuli of noticing the librarian and Ichikawa grabbing her hand, reacts with delayed shock, as the librarian clears her throat at intruding on what seems like an intimate moment between the students, before walking off. He suddenly breaks the grasp on her hand, and walks off towards the door, saying it was a close call, and justifying his actions by saying he was afraid she would get banned from the room if she got caught. She reacts with what seems to be anger, noticing the crushed chocolate oozing from her hand, but when he says she should go wash her hands, she tells him to go, and she sneakily licks it off once his back is turned. He says maybe she should stop with the snacks, and he's sure that their time there is over.

The next day, Ichikawa returns to the library, seeing that Yamada is still there, but now seemingly studying instead of snacking. As he gets closer, though, he notices the package underneath her paperwork, and she brags about only bringing two-thirds her usual amount. He concludes that she won't change.

* A bonus page is Yamada asking about the chip bag she handed to him in Chapter 1, and whether he threw it out. He says that he did not, and she asks why. An image shows that he put it in a zip-lock bag.

* Another bonus is a close-up of Yamada's face advertising the Volume 2 release.

## Trivia

Various earlier Extras seem to take place after this Chapter, primarily indicated by the sudden inclusion of Yamada's homework on the desk, where she now hides her snacks. This is supporting by a Tweet by Sakurai Norio, where she discusses the theory.
Extra 113.1

**Extra 113.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* An image of "Professor" Yamada holding a whip, with the author avatar of Norio Sakurai tied to a chair and drawing. A caption above them reads "BokuYaba will continue."
* An announcement for the cast of the anime, showing Kanzaki, Adachi, Oota, and Hara.
* Yamada is wearing a special beanbag sweater, and is having a ton of fun running around in it. She trips and falls, and Ichikawa walks by holding a book. Taking her to be just a normal bean bag, he takes a seat, looking comfortable, but she pops her head out like a turtle, surprising him.
* A colorized Extra, Yamada is borrowing some of Ichikawa's clothes, a t-shirt and undershirt, though she complains that it's a little bit tight. He turns away from her at this statement, and she says it isn't quite right. He asks what she means, and she clarifies meekly that it's the shirt. He doesn't hear her, and she repeats the boyfriend shirt. A thought bubble in her head shows her imagination as her wearing an oversized t-shirt, which, due to their size difference, is obviously not a possibility.
Extra 23.1

**Extra 23.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

Yamada announces to Ichikawa that they are going to play "The Things You Like Game." She is going to say a list of things that she likes, and if Ichikawa also likes any of them, he has to say "like you." He doesn't get the point of the game, but decides to play along. She begins a long list of random items and concepts, and Ichikawa remains silent to all of them, until she points and says "myself." After a moment's reaction, he says "like you," and she replies, "me too!" and for a moment he feels as if the soul is leaving his body. She clarifies that those who don't love themselves can't love others, and he nearly collapses onto the table, thinking he is safe.

## Trivia

The full list of things that Yamada lists off are Welsh Corgi, Milk Tea, Macaroons, Cocoa with Whipped Cream, Thick Pancakes, the main menu beef bowl of restaurant chain Densetsu no Sutadon-ya, Mushroom Mountain biscuit snacks, and the rival snack that looks like bamboo shoots, before finally ending on "Myself."
Chapter 24: I Wasn't Picked

**I Wasn't Picked** is the twenty-fourth Chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

It is the day of workplace observation at the school, and Ichikawa is going over the more morbid options that would be his preference. He is invited into Adachi's group, but they realize that the numbers won't work, as they need groups of six, so they decide to split their numbers to accommodate Hara's group and Yamada and her friend's group. Adachi and Oota immediately head for Yamada's group, but Moe confronts them, saying she'd rather have Ichikawa and Kanzaki, which moves Ichikawa. Chi agrees that anyone would be better than Adachi, and he begins to make up excuses to justify himself joining their group. He explains that Kanzaki wants in Hara's group, and Moe says that they'll deliberate over who to choose. After some back and forth, they eventually decide to go based off intelligence level, and Ichikawa lies, saying he got a 40 in Chemistry, balancing the groups so that he gets to be with Yamada. While Adachi tries to make peace with the other girls in his group, Yamada leans over and asks Ichikawa if he lied. He freezes up, asking himself how she figured it out.

The group is then seen arriving at their workplace observation destination, notable manga publisher Akita Shoten's main headquarters. Hara, Kanzaki, and Oota's group end up going to Ringer Hut, a Japanese restaurant chain, and when Oota and Hara get excited together, Kanzaki pinches his stomach in jealousy.

## Trivia

* The piece of paper on Ichikawa's desk can be read, to show that he actually made a 92 on the test.

* Akita Shoten is the company that publishes *Boku no Kokoro no Yabai Yatsu*. The real-world location of the headquarters is here.

* It seems likely that Yamada is vouching for Ichikawa during their conversation, but the other girls dismiss her assertion that he is normal. She first says something, they react with shock, she says it's "normal," then Moe clarifies that her concept of "normal" isn't normal at all. She also seems upset in the following panels, crossing her arms, and puffing out her cheeks, when Moe said three of the four girls chose Kanzaki. She then goes out of her way to keep Kanzaki out of their group by bringing up that he wants in the other one, and she glares at Ichikawa to back her up, which he does. She seems to ultimately get her way when Ichikawa joins.
Chapter 2: I Became Furious

**I Became Furious** is the second chapter of *Boku no Kokoro no Yabai Yatsu*.

## **Summary**

The following day, Ichikawa is fantasizing about his knife still in Yamada's pencil case, but instead finds it sitting on his desk when he gets to class. He considers how she returned the knife and that she is aware of his seat's location, and considers how this factors in to his assassination attempts.

Later, in Classroom 2-3, the kids are preparing for their presentations. Yamada asks her friend Moeko Sekine why the part she worked on isn't there, and Moe replies that she rewrote the whole thing, calling her work "totally bad." Yamada tries to explain how she didn't have enough time, and Yoshida Serina interjects, also saying that Yamada's handwriting sucks. This all infuriates Ichikawa, who was the only witness to her hard work in the library, but as she seems to shrug it off, he does nothing about it.

Moe steps in front of the class to give her lecture on political parties, alongside Yamada, who is visibly hurt from being put down by her friends. Ichikawa notices this and connects the dots with their conversation, again becoming angry with Moe's careless words. Ichikawa gets up in front of the class alongside Shou Adachi and Kenta Kanzaki, but since Ichikawa made the poster, he lets Kanzaki speak. He instead spends the presentation staring at Yamada, who is still upset at having her work ignored. Eventually he notices her tearing up, and is taken aback that such an insignificant thing could hurt her so much, but when he recalls her working, he dismisses the idea. Outside of the school grounds, multiple helicopters bring the attention away from the presentation as the kids begin looking outside, in the direction of the crying Yamada, who is seated near the window. Fearing that she will be found out and it will cause her more distress, Ichikawa brandishes his knife and loudly slices the poster he made as Kanzaki finishes his speech, causing the kids to switch focus to him. By then, however, Yamada has already switched her attention to the helicopters, joking with Moe that one looks like an osprey, and making Ichikawa's action meaningless.

## **Trivia**

* This is the first chapter to have notable characterization and speaking roles for Moe and Serina.

* Ichikawa first calls Moe a "slut" here, a secret title he will bestow upon her for many more chapters.
