Chapter 118: I Was Putting Up Walls

**I Was Putting Up Walls** is the one-hundred-and-eighteenth Chapter of *Boku no Kokoro no Yabai Yatsu.*

## Summary

Ichikawa recaps the recent events leading up to him running into Yamada, and finds himself reeling at how gorgeous Yamada is as he realizes that her hair must be for her role in *Your Color's Octave.* She notices Kinoshita, and asks him if he is a friend of Ichikawa's from Elementary School. She mentions how she recognizes him from Ichikawa's yearbook, and begins asking him questions, but he reacts as though he's made of stone. He turns uneasily to Ichikawa, muttering about the perks of public co-education, while grinding his teeth. Yamada nudges him with his elbow, and Ichikawa introduces her as a friend from class. She tries to bring up her hair, but he ignores her, concerned about Kinoshita finding out. Yamada then rushes off, saying she wants to buy something, and that they'll meet up after the live show. Kinoshita continues to mutter, asking about the live show, and Ichikawa is surprised that he says "live show" like a native English speaker. He thinks back on when everyone found out about their grades, and how he made excuses like his stomach hurting not to tell them about it. He realizes that he was the one putting up those walls, and wonders how Kinoshita sees him now. Suddenly he exhales a huge breath of air, rambling about how the scent of a girl lessens his lifespan. Ichikawa says that for someone so smart, he sure is stupid, with Kinoshita making a retort about seeing him in court. Ichikawa apologizes, saying he never called him or Takano. He smiles it off, but says he has to leave, or else "the Gates of Hell will close," meaning his curfew. As he heads off, Ichikawa yells out that the girl from before is actually his girlfriend, and Kinoshita nearly loses his glasses in at the statement, again commenting on public co-education.

Meanwhile, Yamada is waiting on the street, now wearing a cap, when a strange man walks up to her and suddenly starts hitting on her, talking about tickets to an event. As he continues talking with her, Ichikawa walks past him, silently grabbing her hand and walking her away. She says he seems cheery, and he replies that they hadn't seen each other in two-and-a-half years. She asks if he had fun, but he says not really. She nervously touches the brim of the hat she put on, and says her hair will only be like this while filming, and will be back to normal in about a month. He asks her about it as he turns the tickets in to the man at the counter, saying he thought she left just to be considerate, which she admits was part of the reason. As they walk into the arena, he says he wishes she had stayed, lifting the brim of the hat and staring into her eyes, saying he wanted to brag to him about his girlfriend. He quickly loses his nerve, though, and breaks contact, hugging himself in embarrassment. Yamada declares that he's getting the hang of this, and he reacts sarcastically.

## Trivia

Yamada misunderstands Ichikawa as not liking her blonde hair, which is why she buys the hat and tries to reassure him that it will be back to normal in a month's time.
Chapter 27: We Got Separated

**We Got Separated** is the twenty-seventh chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

Now separated from the rest of their group, Yamada begins apologizing, but Ichikawa, trying to play it cool, says another train will show up, even though he's secretly excited at the prospect of being alone with her. His attention shifts when she blames herself and begins crying, and he tells her to sit, and that the next train will be in seven minutes. He begins to become self-conscious, wondering if she's embarrassed to be around him, and gets upset at the people staring at her as they pass by, wondering if they think that he's the reason for her tears. Noticing a vending machine, he walks over and buys her a Royal Milk Tea, telling her that drinking something couldn't hurt. She blushes furiously while staring at the drink, but Ichikawa, oblivious, thinks he got "a miss." Trying to start small-talk, he sits down and mentions how it was his fault since he didn't make a grand enough proclamation of himself going to the bathroom to the others. Imagining him raising his hand and yelling out his intentions to the others, she breaks into laughter, and when she turns to him, she realizes he is on the furthest chair from her.

In time, the next train arrives, and they board. Ichikawa begins worrying about her being involved with her, because people may recognize her from her model work, so he tries to walk away, but she grabs him by the backpack, saying they'll get separated again. She brings up Hara and Kanzaki's group and them going to Ringer Hut, and how great that is, but he counters that it wouldn't mean they just get to eat. He says he enjoyed their trip more than if they had gone there, and she agrees. She then asks if those two are maybe going out, how amazing it is that people in the same class are going out, and how kids in elementary school were just dating in the open, to which he offers vague affirmations to all of her statements. She concludes that keeping dating a secret might be more fun, which he awkwardly calls "nice," but can't keep the idea out of his head.

They finish their ride, and eventually meet up with the rest of their group back at home. Yamada has a bag full of fried chicken, and is happily munching as Moe greets her.

* A bonus page is Yamada consoling Chi, who blames herself as the group leader for not paying attention and getting them separated.

## Trivia

* Ichikawa knew that Milk Tea was Yamada's favorite drink from her telling him directly in Extra 17.1 and indirectly in Extra 23.1.

Chapter 18: I Wholeheartedly Participated

**I Wholeheartedly Participated** is the eighteenth chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

During lunchtime, Ichikawa witnesses Yamada stash her milk carton into her bag, while she lies to her friends about having already drank it. He imagines a cute scenario where she is feeding abandoned baby animals with it, but when he gets to the library he realizes she is using it to create pruiche, a mixed liquid sweet. Realizing that her attempt will be disastrous, he quickly interjects as she's about to pour the mix into her milk carton. He blurts out that she's going to make a mess, but she says she has no bowl, and he replies that there is one in the Home Economics room. She lets out a big smile and tells him to bring her one in a sing-song fashion. He angrily heads for the door, but she cuts him off, saying she was kidding. She instead hands him her milk, and he follows behind her to their destination. He tries to strike up small talk by discussing her recent obsession with complicated snacks, to which she replies she enjoys cooking, which exasperates Ichikawa, who can't even begin to think of these things as something culinary.

They reach the Home Ec. room, but find it locked. Yamada immediately begins bringing her pruiche package towards the milk in Ichikawa's hands, and he proposes the Chemistry Room instead. Inside, he carefully measures the liquid using beakers and small metal weights, which Yamada finds hilarious. She mixes the ingredients, and grabs Ichikawa's hand by the wrist, dipping his finger into the mixture and telling him to taste it. He does so, and she begins drinking her concoction. At about that time, a teacher enters the room, and, seeing their heads poking out from behind the table they are behind, demands to know what they're up to. Ichikawa steps up, stammering that they had forgot something in the room, while the surprise causes Yamada to choke on her drink, spilling it all over herself. Ichikawa looks down, realizing what the scene looks like, and immediately yells out that they were making pruiche, as Yamada yells his name in surprise.

* A series of bonus pages is Chi and Yamada walking, then Yamada losing her balance and backing up into Ichikawa.

## Summary

* A series of alternate-perspective, first-person images from Yamada and Ichikawa's Christmas Eve venture. Additionally, Yamada looks at the fireworks, calling them pretty, but Ichikawa acts unimpressed by something so artificial as a cover for being overwhelmed at seeing her. Someone behind them takes a picture, and he worries that they'll upload it online, with her fans getting upset at her being out with a guy. He grabs her arm and pulls her out of sight of the camera lens, but pulls her too close, and apologizes as they both blush.

He took it to mean "my present (to you) is this (sexy picture)."

Yuki is a very tall muscular man, well over a head taller than his daughter, who is known for her height. This, plus his overlong hair that tends to hide his face, makes him a very intimidating sight to those who don't know him.

## Personality

Yuki is a quiet and reserved figure, but his gruff and short manner of speaking makes him seem more threatening than he is. He works as a chef, which seems to have influenced his daughter's gluttonous habits. He enjoys playing video games, but doesn't often have people he can play with. Based off of their interactions and Yamada's talks about him, he is very protective of his daughter, and seems to have some reservations about Ichikawa's interactions with her, like when he insinuated to him that it wasn't good for kids to be at other peoples' houses after she recently stayed at Ichikawa's place. Despite this, he seems to be forming an uneasy friendship with him.

## **Etymology**

* **Yamada** means "mountain, hill" (山) (**yama**) and "field, rice paddy" (田) (**ta**/**da**).
* **Yuki** means "excellence, superiority, gentleness" (優) (**yu**) and "hope" (希) (**ki**).

Chapter 21: I Kept Quiet

**I Kept Quiet** is the twenty-first Chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

Chi is trying desperately to keep Nanjou at bay, telling him that it is no good trying to get Yamada into a swimsuit or anything else for the indoor waterpark "Summerland," which he is inviting her to. He tries to change the subject to taking her somewhere else, while Ichikawa, who is witnessing all of this, malds by the sink, washing his hands. Chi counters that she has an early bedtime, garnering internal praise from Ichikawa. Changing tactics, Nanjou focuses on Chi, instead inviting her, causing her to become flustered, and Yamada's wall of protection to crumble.

Back in the classroom, Yamada is acting somber, and when Chi asks, she says she isn't going to the waterpark. Chi considers inviting Moe, while Yamada tries to find a way to address that she is being used by Nanjou to lure Yamada in. She tries to imply that he is a bad person, but beats around the bush and doesn't get her message across.

Later, in the library, Ichikawa walks in as Yamada is wiping her tears. Noticing this, he immediately heads back out, but she notices him outside the room, and asks why he's not reading inside. He tries to deflect that reading outside might seem more like a terrace seat, and she asks if the room is a cafe. He realizes that she saw right through his excuse, and follows her back to the classroom, where Moe is loudly explaining to Chi that she is being used. Serina insults him in agreement, but Moe says that it's the thing that's best about him. Chi tries to divert attention from her mistake, saying that she did it off a dare, but when Yamada comes in, she tries to talk to smooth things over. Yamada ignores her despite several attempting callings, culminating in her calling her a "huge, shitty, stupid broad" to get her attention, causing her to chase her across the school. Ichikawa walks off, feeling happy that the fluffy peace between girls has been protected again.

## Trivia

Summerland is a real indoor waterpark in Tokyo.

Adachi Shou

* Anime
* Manga

**Adachi Shou** (足あ立だち   翔しょう, *Adachi Shō*) is a secondary character in *Boku no Kokoro no Yabai Yatsu*. He is initially Ichikawa and Yamada's classmate in Class 2-3, but goes to a different class from them in the following year (Class 3-2).

## Appearance

Adachi has very short, brownish-blonde hair and an average build.

## Personality

Adachi is a brash and perverted teenage boy, but he has a strong sense of male honor. He is unapologetically perverse about and even around women. He and his friends are often thinking up games to play with the girls that will unwittingly involve them in some kind of mild sexual gesture, like saying something naughty with a tongue twister, or learning about their supposed fetishes from an internet post. He even comments on wanting a sex slave like Yamada. This makes him something of a pest for most of the cast, and many of them roll their eyes at his weird antics.

## Relationships

### **Ichikawa Kyoutarou**

Adachi somewhat bullies Ichikawa early on in the manga, and the two seem to have a mutual dislike of the other. Adachi uses Ichikawa to try and get Yamada's contact info, and acts as though he's going to punch him during a misunderstanding while they are drawing gravestones, mostly to look cool and tough to the other classmates. The two cool towards each other over time, and even have a few oddball conversations, culminating in Adachi challenging him at the sports festival. The two can be seen as masculine rivals to one another.

## Etymology

* **Adachi** means "leg/legs, foot, paw, stick, limb, shank, pace, step, pes, tread, footstep/footpace, skirt, glutinosity, clutch, spiculum, pediment, adhesiveness, clamminess, stickiness" (足) (**a**) and "standing" (立) (**tachi**/**dachi**).
* **Shou** means "soar, glide, fly" (翔).

## Trivia

* Adachi is part of the Judo Club in their school.
Extra 47.1

**Extra 47.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* Class 2-3 are having an art day, and Adachi has drawn a non-too-flattering picture of Ichikawa, his partner for the assignment. He tells him to draw it seriously, but when he turns it in, the art teacher says it looks quite like him, leaving Ichikawa shocked. He looks over at Hara's art of her partner, who happens to be Yamada, while the two gush over having each other as partners. Ichikawa is impressed with her art, saying that he should have expected nothing less from the art club, and leans over to admire it more. Yamada is not too pleased with him getting so close to Hara, and stares them down, which Hara recognizes while Ichikawa remains oblivious. Whilst Hara panics, Ichikawa comments that she should add the two moles on Yamada's neck, and doing so would make it perfect. Hara, seizing on the opportunity, brings attention to his eye for detail, and Yamada's discontent turns to embarrassment that he pays such attention to her features like that. The final panel is Hara looking pleased at setting the mood for the two of them, while Yamada hides her face bashfully behind her artwork, and Ichikawa frets about potentially grossing her out.

* Another artwork, in reference to the previous piece, is Yamada and Ichikawa in the library. She has pulled her hair to the side, displaying her moles, and he looks on, confused.

* These Extras contain the cover art for Volume 4 of the collected manga, which is of Yamada and Kyoutarou walking outside at night, a large color page of them walking across the street, and a table of contents.

* Another page follows immediately after the previous Chapter, with Yamada fretting about him seeing her back and her bra, and backing up, but realizing that she's backed into a mirror where he could still see. As she moves around, she makes a lot of noise, and he tells her to shush, since his sister is still next to them. He suddenly gets several messages from Kana, and she is complaining about the couple secretly flirting in the stall next to hers. Yamada is suddenly curious about what messages he got, and demands to see, but he refuses and protects his phone.

## Trivia

Ichikawa's artwork of Adachi can also be seen, and it's of his decapitated and rotting head.
Wantaro

Wantaro as he appears in Chapter 104 of the manga.

**Wantaro** is Yamada's pet Welsh Corgi.

## **Appearance**

Like most Welsh Corgis, Wantaro has a brown upper coat and a lighter, cream-colored coat around the belly and paws.

## **Personality**

As is the case with many small dogs, Wantaro is mischievous and likes to get into things he shouldn't. He is sometimes used as a device to cause conflict in the story, like when he attempts to pull down Ichikawa's pants, or nuzzles Yamada's chest, making her wonder if it was Wantaro or Ichikawa who touched her.

## **Trivia**

"Wan" means bark in Japanese, and "-Taro" is a common male ending to names. A vague English equivalent might be Mr. Barks.

He has a dog cage in the living room of Yamada's Apartment.
Chapter 32: I Can't Keep Distance

**I Can't Keep Distance** is the thirty-second Chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

Class 2-3 is gathered outside for a period of marathon running, with Ichikawa monologuing that it is one of the worst events at school. Each student begins at their own pace, with Yamada starting beside Hara, but she leaves her behind when she tries to get beside Ichikawa. As a matter of manly pride, he is determine not to get overtaken by her, and when she grabs his shirt, he accelerates, leaving her behind. When he checks behind himself, though, she is out of breath and sweating, and takes off her outer layer, causing him to slow down to check her out. As he does so, he notices that the shirt to her gym uniform is on backwards, and informs her. She passes him her jersey and brings her arms into her shirt, spinning it around to the proper orientation, but leaving him overstimulated and lagging behind. She lowers her pace to match his, but mentions that she can see his right eye for the first time, due to his running pushing his hair out of the way, leaving him self-conscious and clamping his hand over it. While the two have their fun, they don't even realize that they have left the track as it curves, and are walking off towards the school building. They quickly correct their orientation, then finish their lap, being the last two to finish. Yamada collapses to the ground, exhausted. After catching her breath, she offers her hand to be helped up, and he glances quickly around to see if anyone is watching, then helps her up. She lovingly slams her shoulder into his as she works her way to her feet. Yamada talks with Hara about her pace, and Ichikawa, still holding onto Yamada's jersey, grabs his own and walks up, passing one to her.

Back in the classroom, Ichikawa is smoothing out the jersey in his hands, and notices that it is Yamada's jersey, and that Yamada is now tying his jersey around her waist while talking to Chi.

* Bonus artworks are a color page of Yamada trying to talk to a nervous Ichikawa, and Yamada posing with a Volume 2 copy of the manga behind her back.

Extra 117.1

**Extra 117.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* A series of five images counting down the days until the first episode of the anime adaptation of BokuYaba. First is Yamada with her hand out for five days, second is a back shot of Yamada with four fingers out, third is Serina, Moe, and Chi each offering a finger each, fourth is Yamada and Ichikawa in close proximity with one finger raised, and finally, an image of Yamada with one finger raised to her mouth.
* A color image of Yamada and Ichikawa preparing for the anime's first episode. She is sitting on a chair with him in her lap, but she has fallen asleep and has fake eyes drawn over her eyelids. He's looking up at her sleeping face apprehensively.
* An Extracanonical short manga detailing one of the times that Norio Sakurai got to attend a dubbing session for the anime. She arrives with an imaginary schoolgirl, named Sonoda Kaoruko, in a studio in Tokyo. Norio offers snacks to the team, and the voice actors come in to begin their job, and each actor is depicted as the character they are playing (i.e. Yomiya Hina is depicted as Yamada Anna, and so on). Hina Yomiya is noted as being cute, expressive with her hands, cute, beautiful, and so cute. Shun Horie is depicted as acting similarly to Ichikawa, and requests retakes even when not asked of him. Norio reacts with mirth when Oota says "dick," with Sonoda berating her for her immaturity. The director requests a harsher tone from Asai Ayaka as Chi, when dealing with Yamada, which she apologizes to Hina Yomiya to, and the mangaka and her friend react with gushing sympathy over such a cute exchange. When Tamura Yukari voice-acts Kana saying "I love you," Norio's brains melt and begin pouring out of her nose and ears from the sheer cuteness. Norio frets about eating all the snacks, and the recording session goes very smoothly overall. During a break, she overhears some of the cast commenting on how funny BokuYaba is, and it immediately goes to her head, despite Sonoda's warnings. She says that they probably say that to all the creators, but she reasons it out as though she's not a world-famous Shonen Jump mangaka, and Sonoda relents, saying to be as happy as she wants to. Later, she goes to the toilet and runs into Hina Yomiya and Asai Ayaka, who are washing their hands. In the stall, Norio stares, intimidated, as the toilet, refusing to use the same one as the actors. Back in the studio, she holds it in as recordings start back up. She concludes with a paragraph detailing how she went to two different sessions, and was very happy with what she saw, asking the audience to continue tuning in. Sonoda requests that they only use this panel in the Extra, to avoid any weirdness.
* An image of Yamada holding out her skirt and doing a twirl, in celebration of the second episode of the anime.

## Trivia

Norio Sakurai's author avatar is labeled as a ten-year-old girl in the manga short.

An imagination spot involves them dressed up as the leads, with the actual character busts behind them, and Yamada acting tough in front of Ichikawa.

## Trivia

The "Last of the Wolves" artwork is part of a promotion for the movie made by various other mangaka, as seen here.
Extra 94.1

**Extra 94.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* Taking place during the previous Chapter, Ichikawa is first walking into the bathroom, and Nigorikawa whispers in his ear that it's "Yamada's Stew," which he tells him off for. He refuses to interact with or even look at the water in the tub, and takes his position on the small cleaning stool. As he does so, he realizes that she must have also sit there, and begs himself not to "stand up" as he tries to calm himself.
* Yamada is standing in a line with other students, pointing forward and looking to the side.
* Yamada and Ichikawa are walking home from school and she shows off a handful of flower petals. He asks if she took them from a tree, but she insists that she picked them from the ground. She then dumps some of them on his head, and others on her own head, then declares a game where the first person to have them all fall off loses. He internally asks if they're Kindergartners, and she tries to distract him by pointing in the sky and saying she sees a flying humanoid, but he doesn't take the obvious bait. She keeps pestering him, asking him to look at her, but isn't paying attention and bumps into a pole with her arm. He suddenly grabs her, asking if she's okay, and he believes that he's lost as all the petals fall. She playfully headbutts him, though, dropping the remainder of her petals onto his head, and declaring it her loss.
Kouda Nico

Nico as she appears in Chapter 81 of the manga.

**Kouda Nico** is a secondary character in *Boku no Kokoro no Yabai Yatsu.*

She is a fellow model in Yamada's agency, and has an obsession with her, bordering on stalking. She is 19 years old as of Chapter 101.

## **Appearance**

Nico has short, silver (likely dyed) hair that extends just below her statuesque face. She often wears multiple earrings and a necklace, along with fashionable clothes befitting her job as a professional model.

## **Personality**

Nico appears to have a different persona depending on who she is interacting with. Her first appearance shows her as a picturesque, ethereal model, but this facade immediately falls away when she notices Yamada, who she cries to because a taxi driver didn't notice her when she needed a ride. She has a secret Twitter account which she uses to roleplay as an obsessed fan of Yamada's, leaving out the fact that they work together professionally.

## **Trivia**

* The Pig Man Twitter account is a real account, assumedly created by Norio Sakurai. The only content on it is a special piece of artwork, seemingly of Nico lamenting not being as close to Yamada as Ichikawa is. https://twitter.com/pig\_man1209
* She is first referenced in Chapter 5, 76 Chapters before her first appearance.
* Models or idols that she appears to be a fan of are Saito Honoka, Akino Anna, Aoyama Yui, Takioka Ririka, and [cut-off] Ellie. All are listed on her Twitter account.
Chapter 65: I'll Soon Be An Adult

**I'll Soon Be An Adult** is the sixty-seventh Chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

In Ichikawa's room, Lucifer Nigorikawa is lecturing Ichikawa, telling him about how much progress he's made with Yamada just from visiting her apartment. He tries to dismiss it, however, saying she is just treating him like any of her other friends. He considers how he doesn't know the difference between the distance in friendship and lovers. He leaves and begins biking to school, thinking on how he no longer has his cast on, but notices that something is wrong with his voice.

At the school, he encounters Yamada and Chii, the latter of which points out his healed arm, and advances towards him, but Yamada pulls her away and says she noticed first. Chii brings up a silly story where Yamada ate six rice balls yesterday, but she corrects her, saying it was only five, six was the day before. He gives a non-committal "that's nice," and Chii laughs, saying he's the same as always. Yamada asks if his arm is completely healed, and he says he can't lift heavy things.

In the classroom, Yamada sends him a text, saying that it's fine if he doesn't want to talk in public, but to at least look her in the eyes at school. He turns around to look at her in confirmation, and she brightens up, as he considers how that isn't what the problem is. They meet up in the library later in the day, and he brings up how he's been having trouble speaking. She panics, thinking it's a cold, but he says that his voice is just cracking. She's not convinced, so he distracts her by bringing up how his right arm is now thinner, offering both arms as comparison. She squeezes them to compare, but quickly stops, still fretting about him being cold, but he keeps denying it, even as his voice cracks again. He says that his voice is just changing, and he thinks back to when he told her that she was growing up in the previous Chapter, and now considers how he's the one who's scared of growing. He considers again how she may just be treating him as any other of her girl friends, and how he may be okay with that for now, but she becomes amazed at his statement. Excited, she begins listing off the possible changes he may have, like a deeper voice, and growing facial hair. She offers to get some red rice, but he says that's not what it's for. She takes his arms back into her hands, and compares, saying that his right arm didn't get thinner, his left arm got thicker. He thinks about how she is constantly noticing things he doesn't, even about himself, and how she always points them out. She says how she is looking forward to his changes, and leans forward, saying she wants him to call out to her all the time once his voice gets deeper. She realizes that in holding his arms out and getting closer, she has brought his arms to her chest, and she recoils in embarrassment. Nigorikawa materializes and urges Ichikawa to go for it, as the two look away from each other.

## Trivia

Yamada recommending Ichikawa eat red rice is a common thing for girls during puberty, in reference to periods, which obviously doesn't apply to him.

Your Color's Octave

***Your Color's Octave*** is Yamada's favorite shoujo manga. She convinces Ichikawa to borrow it, and it acts as a catalyst for advancing their relationship.

The actual content of the manga is not well-documented in *BokuYaba,* but it apparently follows a female lead named Sakura and her affections and interactions with a cool pretty-boy named Nigorikawa. Sakura also has a close friend named Miria, that Yamada will be playing in the live-action adaptation of the manga.

Ichikawa is initially annoyed by the male lead, thinking him too aloof and full of himself, but begins questioning if Yamada sees his personality and actions as similar to Nigorikawa. Later on, Ichikawa conjures a mental image of him called "Lucifer" Nigorikawa, who tries to push him in the right direction with Yamada.

## Cast

The main cast of Your Color's Octave is apparently composed of six characters, based off the character lineup in Chapter 117.

Sakura - Female lead, often "flutters" next to Nigorikawa, seems shy and easily flustered.

Nigorikawa - Male lead, blunt and prone to insulting people, but actually very kind. Usually cool and collected, but has moments of clumsiness, like when he accidentally tears a chip bag open and spills the contents.

Goto Miria - Sakura's "gal"-like best friend. In a forbidden relationship with her Japanese teacher. Has a steamy scene where they have a shirtless hug.

Miria's Japanese Teacher - School faculty with a secret past. A scene from the manga shows him with a giant back tattoo, showing an Eastern-style dragon, and implying he has a past associated with the Yakuza.

Extra 68.1

**Extra 68.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* A timeline of events showing Ichikawa and Yamada interacting, and how he's slowly come to get closer and sit next to her as the seasons have changed. His progress is shown via a silhouetted outline of his body beside the bookshelf, standing next to the table, and now him sitting at the table properly as it changes from Summer to Fall to Winter. She brings up how he's moved since the summer, and he becomes self-conscious at her noticing. She concludes, wondering if Spring will come soon, and he laments that she's still a girl that he doesn't fully understand.

* A sheet of BokuYaba stickers featuring scenes from the manga.

* Yamada is snacking on small pieces of chocolate bread from a package, called Chocolate Anpan. She says she loves it, but he prefers actual Anpan, which has red bean paste inside instead of chocolate. He says the name makes no sense because it's not what it advertises. Yamada puts on a smug expression, and opens her mouth wide, closing her eyes and going "~Aaaaaan." He considers putting the piece in his hand into her mouth himself, but flinches, and she stops, saying that's the kind of "An" that the snack is referring to. He thinks how close he got, while hiding the piece behind his back.

* Using the same package of Chocolate Anpan, Yamada tells Ichikawa to read what she points to. He says "Choco(late) Annnnn..." and holds it for a time. She gets distracted fishing for another piece of bread, planning on putting one in his mouth like he had considered doing, but the package is empty, and she gets frustrated, yelling that there aren't any left, and pushing the bag away.
Extra 24.1

**Extra 24.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* A follow-up to Extra 23.1, Yamada calls Ichikawa strange for not saying he liked anything in her "The Things You Like Game," and he goes through his head considering various activities, telling himself he's not the type to dish out high praise. She says she wishes he was a bit nicer, but when he presses her on what she means, she tells him to forget it. She then fishes through her bag and pulls out a bag of cookies, the ones she made during first and second period cooking class. He tries one, leaving her in suspense, and then saying that they're really *close* to being tasty. She asks him what can be improved, and opens up a notebook to write down his recommendations, saying that Moe was the one who gave her the recipe. She reacts with bright enthusiasm at the idea of improving her recipe at home, and Ichikawa feels like dying from being exposed to her expression.

* Yamada asks Ichikawa what kinds of food he would have if he were on a game-show called "The King Won't Eat." They go through an elaborate listing of various foods and determine how they would do.

* Another part is a color page of Yamada and Chi walking outside. Chi makes a comment about it being Sakura Day, which Yamada misunderstands due to a Japanese pun, making Chi consider the idea of a 96-day-long month in March.

## Trivia

* This Extra confirms that Moe is in the cooking club.

* This is one of the Extras that appear to have happened after Chapter 30, based off of the placement of the homework hiding her snacks.

Chapter 12: I Can't Sleep

**I Can't Sleep** is the 12th chapter of *Boku no Kokoro no Yabai Yatsu*.

## Summary

Ichikawa is in the Nurse's Office, complaining of an apparent headache, which he refers to as bugs in his head. He notices a pair of shoes labeled "Yamada" on them next to a bed, and tries to convince himself it is another Yamada from the one in his class. The nurse comes in and takes his temperature, which is high, but not fever level. She lets him stay through the next period. As she begins to walk off, she brushes against the curtain surrounding the bed next to Ichikawa, revealing Yamada Anna's napping face. His nervousness at having seen her causes his headache to flare, and when he tries to close the curtain, she awakens and they both turn from one another. She says she was afraid someone she didn't know had been watching her, and was relieved when it ended up just being Ichikawa. She then asks him what is the matter, and he says he has a headache, and she replies she has a stomachache. She then fishes in her pocket, pulling out a huge handful of candy. She drops the candy, producing a hidden medicine package from inside the pile, and hands it to Ichikawa, which he takes despite some misgivings. He takes the medicine to the sink to get some water, and notices one of two capsules had already been taken, along with the nearby used cup, and connects that she had used the cup to down her own medicine previously. He nervously lifts the drink to his mouth, but Yamada gets up and announces she's "gotta go" and leaves, causing him to choke on the medicine.

Ichikawa lays back down, but realizes she forgot the jacket piece of her jersey. He argues with himself on whether or not to take it and give to her, but the nurse comes back in, and, discovering the candy and jersey, tosses the latter onto Ichikawa, telling him to return it when he goes back to class. He indulges in the smell, calling it an "act of God," and notes that the bugs have moved lower into his body.

Later, as Ichikawa returns to class with Yamada's jacket, she begins rushing out of the classroom. He tries to bring up the jacket in his hands, but she rushes past, only concerned about her sweets.

## Trivia

* First appearance of the school nurse, who is as-of-yet unnamed.

* A tweet by Norio Sakurai during the airing of the associated episode of the anime confirms that Yamada was on her period this chapter.

Extra 22.1

**Extra 22.1** is an Extra in *Boku no Kokoro no Yabai Yatsu*.

## Summary

* Yamada wants to play a game of improvised Shogi using pieces of chocolate, though Ichikawa doesn't know how to. They play through a mock battle, with Yamada ultimately surrendering, and giving him the remaining chocolate as a reward, which she claims is a rule.

* In the library, Yamada declares to Ichikawa that he is much like a cat. He doubts her, and thinks internally that she is the one like a cat. She tells a story about a stray that she encounters on occasion, and how she has been slowly able to get closer and closer to it over time, counting down the meters until it ran away each attempt. When she says she got up to one meter, Ichikawa turns to her just as she has presses up against him, and he darts off. "See?" she says with pride, as he clutches at his chest, saying he'll kill her for her prank.

## Trivia

* The date on the blackboard behind Ichikawa is for Valentine's Day, so she is, in a roundabout way, giving him chocolate for the special day.

* This is one of the "Valentine's Extras" that were later repurposed for the manga proper when the in-universe Valentine's Day occurred.

* This pages where Yamada calls Ichikawa a cat is one of the Extras turned into a motion comic on Twitter.
