## Background[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=1 "Edit section: Background")]
Due to an increase in the number of transfer students to [Teitan Elementary School](/wiki/Teitan_Elementary_School "Teitan Elementary School") over the past year, they have hired new teachers. She is the new deputy homeroom teacher for class 1-B.
## Personality[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=2 "Edit section: Personality")]
Her personality seems to be that of a well meaning but really clumsy and incapable teacher. She approached the [Detective Boys](/wiki/Detective_Boys "Detective Boys") on the grounds that she is scared of the old warehouse at the school and needed them to come with her. However, once she was out of sight of them, her personality changed dramatically to that of a skilled fighter with a scary face, where she rendered three assailants unconscious with a broom in what could have been seconds.

### Keen observation and deduction skills[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=6 "Edit section: Keen observation and deduction skills")]
She has also shown her reasoning and deductive abilities, giving hints to [Conan](/wiki/Conan_Edogawa "Conan Edogawa") to solve a case. She may also be aware of Conan's peculiar use of gadgets as she has witnessed him tranquilizing [Yamamura](/wiki/Misao_Yamamura "Misao Yamamura"), and using the voice changer bow tie to perform a sleeping deduction show. Conan mentioned using his tranquilizer watch to her on her first appearance.
### Painting[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=7 "Edit section: Painting")]
She is shown to be able to paint a life-sized tiger in a realistic style in one afternoon, and is able to easily fix a smudged painting.
### Firearms[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=8 "Edit section: Firearms")]

Rumi about to attack the robbers.
[Sumiko Kobayashi](/wiki/Sumiko_Kobayashi "Sumiko Kobayashi") introduces her class to the new deputy homeroom teacher, Rumi Wakasa. She appears to be a clumsy, shy and fearful person. Rumi approaches the Detective Boys for their help retrieving quicklime from the old warehouse in the school yard which causes them to come across a dead body. Over the course of the case Rumi uses her clumsiness to give hints to Conan on how to solve the case. Once she was out of their sight, her personality completely changed and she beat up a few robbers.
### Rumi Wakasa's Neighbor Murder Case (Manga: [978-980](/wiki/Volume_92#Rumi_Wakasa.27s_Neighbor_Murder_Case "Volume 92"), Anime: [896-897](/wiki/The_Woman_with_White_Hands "The Woman with White Hands"))[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=12 "Edit section: Rumi Wakasa's Neighbor Murder Case (Manga: 978-980, Anime: 896-897)")]
Rumi overhears an argument between her neighbor and his girlfriend, as she was leaving for school, and smiles. Later she accidently destroys a picture that was going to be used for a school play and she says that she will redraw it. Conan and the detective boys accompanied her to help. After they finish, Rumi treats them to dinner. But when they hear loud sounds from the neighbor, they goes over to check it out and finds a dead body and an unconscious man. Later back in Rumi's apartment, Conan finds a receipt that may prove that she knew the case would happen before hand and invited them there on purpose. Later Rumi incapacitates the culprit under the guise of falling over. The news crews outside happen to take a picture and Ayumi gives them Rumi's name. [Hyoue Kuroda](/wiki/Hyoue_Kuroda "Hyoue Kuroda") is shown reading the news article on his phone. [Kanenori Wakita](/wiki/Kanenori_Wakita "Kanenori Wakita") is shown reading a newspaper, but the article is not shown to us.

Rumi takes the Detective Boys camping. Conan is suspicious of her and thought of strange things that he noticed in her present. When they approach a group cooking curry over a fire nearby, one of them mentions that he has an injured eye and nearly had to get a prosthetic eye. Rumi clenches up, and Conan notices her gripping something in her pocket. Later one of the other campers is burned alive inside his own tent. Kuroda emerges from an adjacent tent and asks her whether the police should be called. However Rumi is standing in stunned silence, staring forward. When she snaps back to reality, Haibara seems to notice that Rumi can't see out of her right eye. Conan starts to wonder if Rumi is clumsy on purpose or because she cannot see. When Kuroda seems to know the order that everyone introduced themselves in, despite originally claiming to have had earplugs in while sleeping. Rumi accuses him of spying on someone. Rumi has the Detective Boys build an acorn balance toy, which leads to the solution of the case. After Conan and Kuroda uncover the culprit, the culprit uses Ayumi as a hostage, Rumi manages to distract him long enough for Kuroda and Yuminaga to arrest him. Kuroda showed interest in the intimidating words that Rumi used to distract him. On the other hand, Conan becomes more suspicious of Rumi, and notices a strange object in her back pocket that has a shape similar to that of a Shogi piece.
### Crimson School Trip Case (Manga: (/wiki/Volume_95#Crimson_School_Trip_Case "Volume 95"), Anime: (/wiki/The_Scarlet_School_Trip "The Scarlet School Trip"))[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=14 "Edit section: Crimson School Trip Case (Manga: 1005, Anime: 928)")]
Rumi with scars.
At the end of the case, news of Shinichi being one of the detectives that had solved the case spread to the internet. Both Kuroda and Wakita were shown seeing the information on their phones. However, Rumi was shown sitting in the dark looking at the [APTX victims list](/wiki/List_of_Black_Organization_related_characters#APTX_4869_Victims "List of Black Organization related characters") on her laptop, with a smirk on her face. The names [Shinichi Kudo](/wiki/Shinichi_Kudo "Shinichi Kudo") and [Kohji Haneda](/wiki/Kohji_Haneda "Kohji Haneda") appear to be highlighted. Additionally this is the first time we see her without a shirt on and she has scars on her upper arms as well as her back.

Rumi and Kobayashi take the Detective Boys out to collect edible plants. As they do so, Rumi detects the scent of blood blown by the wind and immediately thinks about Kohji's death. At the mention of good luck charms, Rumi remembers back to when Kohji said, "With the watchtower bishop, you can be sure of making a good move", while holding up a shogi bishop. Then he says, "So they're going to kill me despite that?" She then remembers him dead, with some sort of blood pouring out of his mouth, and she calls him a "foolish person", while pressing down on her right eye and crouching down on the ground. Conan sees her pressing down on her right eye and seems to connect it to an eye disorder. Rumi sees Conan tranquilizing Yamamura to make his deduction and gives a slight smirk. When Ayumi gives a 4-leaf clover to Rumi, saying that because Rumi is clumsy she needs good fortune, Rumi waits for the Detective Boys in front of her to look away, except Conan who is standing behind her looking at her, and throws away the 4-leaf clover. Conan notices her doing this and appears angry at her for it (or cognizant why she does not feel she needs it) as Rumi's face is in shadow.

Rumi and Kobayashi take the Detective Boys out to a farm to collect chicken. During the trip, she mentions Karasu being black, sly and a conspirator, making Conan suspicious of her as she might personally know [Renya Karasuma](/wiki/Renya_Karasuma "Renya Karasuma") as [Rum](/wiki/Rum "Rum") candidate. They meet up with [Amuro](/wiki/Tooru_Amuro "Tooru Amuro") who is also going to the farm with another purpose. She seems to have a strange glare upon hearing Amuro is a detective. Later, they receive a call from the [Detective Boys Badge](/wiki/Detective_Boys_Badge "Detective Boys Badge"), knowing that Conan, Ayumi, Mitsuhiko, Kobayashi, and Amuro gets trapped inside the farmhouse's cellar as the farm's owner brother uses Ayumi as a hostage and calling them for the police. However, they are unable to contact police by their phone. Also, Rumi notices the shogi piece which has been kept on her back pocket is missing and finds out it has been picked up by Amuro according to Genta. After they are rescued from the cellar, Rumi uses the badge as a bait to lure Amuro back into the cellar and knocks him out in order to retrieve the shogi piece. Rumi tells Amuro that she lost her grip and let go for the trap door cutting all the light, which caused him to miss a step on the stairs.
### Kogoro in a Dilemma (Manga: (/wiki/Volume_99#Kogoro_in_a_Dilemma "Volume 99"), Anime: (/wiki/Yoko_Okino_and_the_Locked_Attic "Yoko Okino and the Locked Attic"))[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=18 "Edit section: Kogoro in a Dilemma (Manga: 1057, Anime: 1060)")]

Rumi, Kobayashi, and the Detective Boys meet the Teitan Elementary School alumni as they are holding a reunion party. When one of them mentions that [Akemi Miyano](/wiki/Akemi_Miyano "Akemi Miyano") also attended the school before, he mistakes Haibara for [Shiho Miyano](/wiki/Shiho_Miyano "Shiho Miyano"), Akemi's younger sister who he'd seen before. As Conan and Haibara are whispering about Akemi, Rumi suspects that Haibara is Sherry in a shrunken state, and that she betrayed the [Black Organization](/wiki/Black_Organization "Black Organization") following the death of Akemi. When Conan rushes outside the classroom to look for someone suspicious after someone triggers Haibara's anxiety, Rumi witnesses Wakita leaving after he delivered sushi.

Rumi takes the Detective Boys to Shizuoka. Conan is suspicious of her intentions regarding Haibara so he asks [Subaru Okiya](/wiki/Subaru_Okiya "Subaru Okiya") to join them. When Subaru asks her why she is concerned about Haibara, she lets slip that she believes Haibara is the daughter of a certain woman who ruined her life. When they encounter the criminal gang involved in the case, Subaru calls for Rumi to take the Detective Boys to a safe place while he uses Jeet Kune Do to fend them off, causing Rumi to have flashbacks of [Tsutomu Akai](/wiki/Tsutomu_Akai "Tsutomu Akai") seventeen years ago after hearing his words. Rumi locks the Detective Boys in a safe place, bending the doorknob to make it unusable, so she can secretly defeat their pursuers. When Subaru arrives and finds the criminals unconscious, Rumi lies to Subaru that they must have fought among themselves, unaware that he and Conan witnessed the scars on her hand.

Her true identity is revealed in the [flashback](/wiki/Case_from_17_years_ago "Case from 17 years ago").
[Show spoilers »](javascript:toggleDisplay( "toggledisplay1", "« Hide spoilers", "Show spoilers »" ))
17 years ago, Amanda Hughes, a fan of [Kohji Haneda](/wiki/Kohji_Haneda "Kohji Haneda"), visited and played chess with him. Amanda introduced her bodyguard, **Rachel Asaka**, to Kohji. Kohji said Rachel Asaka was his ideal girlfriend and he also pointed out that Asaka's right eye's disease is Amaurosis Fugax. After the chess match, fearing that something was wrong after being unable to contact with other bodyguards, Amanda lied to Asaka and told her that she left the knight piece in Kohji's room. After Asaka leaves to get the chess piece in Kohji's room, Rum arrives at Amanda's room with the intention of forcing her to help the Black Organization. Rum tells her that he knows her weakness is her bodyguard, Rachel Asaka - who Amanda considers her daughter, and that if they get their hands on her, then Amanda will be forced to help the Black Organization. To lure her out, Rum will threaten Amanda with a drug the organization created. This however backfires on Rum as Amanda intentionally eats the drug out of his hands so that they don't use her to find Asaka. Due to the drug, Amanda dies but not before leaving a dying message using her wristwatch and a knight piece.
At the meantime, Kohji realized what happened, he asked Asaka to hide and he acted like he didn't know anything when the organization visited his room to find "an Asian-looking woman". Kohji persuaded Asaka to stay in his room for her safety but Asaka didn't want Kohji to be killed for helping her. Kohji knocked Asaka out with a stun gun and hid her in his bookshelf. Before getting unconscious, Asaka warned Kohji that the bad guys would kill him, he handed her his good luck charm - a bishop shogi piece and said "With the watchtower bishop, you can be sure of making a good move. I must carry my initial dream through to the end. (A better translate from its Kanji/Chinese characters meaning)". When the bad guys came, Rum noticed the books in bookshelf must have been touched so he wanted to check, Kohji told Rum he saw a piece of news including him gave a speech for Renya Karasuma thirty years ago to prevent him from checking the bookshelf, Rum let one of his man beat Kohji. Realizing Kohji would not reveal anything about Asaka, Rum decided to kill him. In his last breath, Kohji cut the mirror given to him by his mother to leave his dying message: CARASUMA.
After seeing Amanda's dead body, [Hyoue Kuroda](/wiki/Hyoue_Kuroda "Hyoue Kuroda") quickly ran into Kohji's room as Amanda had a meeting with Kohji that night and only found Kohji's dead body. The only thing he was able to do was take some pictures at the crime scenes. Asaka woke up and thought Kuroda was the one killed Kohji, she attacked him until she was knocked out. Rum then realized Kohji hid Asaka in the bookshelf and noticed the bathroom was messed up badly, he tried to clear up the evidence but they all had to run because the police were on their way.

Yusaku theorizes that she is the one who uploaded the info relating to the Kohji Haneda murder case regularly on the internet to expose those involved with the Black Organization. She would then keep her eye on the people who kept accessing the site repeatedly, which led her to Professor Agasa's PC and in turn, Conan. Yusaku further theorizes that she would then slip her way into Teitan Elementary School so that she could approach Conan. After the case is solved Rum is seen wondering why Rumi would remain at the school and it shows her looking at Haibara while this is happening.

Genta gets kidnapped at an eel vending fair and the Detective Boys, without Haibara, run after the kidnappers' car and embark [Yumi](/wiki/Yumi_Miyamoto "Yumi Miyamoto") and [Naeko](/wiki/Naeko_Miike "Naeko Miike")'s car to chase them. After losing track of them, Conan remembered who the kidnappers were and remembered they used signals at the fair so they try to figure out what they tried to communicate. Then, Mitsuhiko remembered the burning tent case and the reference to the counting system. A flashback of Haibara and Rumi's leg was shown.

### Hints that Rumi Wakasa was not Rum[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=28 "Edit section: Hints that Rumi Wakasa was not Rum")]
* The descriptions of Rum were all of a man, but she is a woman.
* Her name "Wakasa Rumi" seems too obvious.
* Like Kuroda, she perhaps should have recognized Haibara as Sherry and acted against her. However, no action is taken against Haibara despite seeing her five days a week at school.
* Despite the activation of her Black Organization sense, Haibara says she likes Wakasa.
* The photo of the bodyguard Asaka, whose face was not shown, may mislead her as the main suspect because Kuroda and Wakita are both men while she is a woman.
* Rum is a cautious person of whom nobody, not even inside the Black Organization, has an accurate description. If Rumi Wakasa was Rum, she wouldn't have allowed herself to be shown on the news, pro golfer case, with a name so close to the code "ASACA RUM". Members of the Black Organization, like Gin and Vodka, believe that he 'messed up' with the Haneda murder, so exposing herself on the news was a risk if she was really Rum.
* She works as an elementary school teacher, meaning she cannot move around freely to outside of school during working hours and leaving work often will make her more suspicious. If she was Rum and were to move around freely, with or without disguise, there is a possibility that someone will remember her stalking around Mouri Detective Agency.
* In a flashback, she seems to have been traumatized by Haneda's death. Rum was likely the murderer.
* In Rumi's flashback, Kohji Haneda is seen dead and bleeding profusely from his mouth. The palm of Kohji's corpse was open. Which implies that Rumi is not the killer and neither took the piece after prying open Kohji's palm, she might have just picked it up after the real killer discarded it at the scene.
## Relationships analysis[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=29 "Edit section: Relationships analysis")]
### Conan Edogawa, Ai Haibara, and Detective Boys[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=30 "Edit section: Conan Edogawa, Ai Haibara, and Detective Boys")]
Conan, Haibara, the Detective Boys, Kobayashi, Wakasa, and Uematsu.
Rumi is the new deputy homeroom teacher for [Conan Edogawa](/wiki/Conan_Edogawa "Conan Edogawa"), [Ai Haibara](/wiki/Ai_Haibara "Ai Haibara"), and the [Detective Boys](/wiki/Detective_Boys "Detective Boys")' class. She has approached them directly twice to lead them to the warehouse of the school that a robber group had used. Rumi is aware of three of [Professor Agasa](/wiki/Hiroshi_Agasa "Hiroshi Agasa")'s gadgets given to the Detective Boys: the [flashlight watch](/wiki/Wristwatch_Flashlight "Wristwatch Flashlight"), the [detective badge](/wiki/Detective_Boys_Badge "Detective Boys Badge"), and the [tranquilizer dart](/wiki/Stun-Gun_Wristwatch "Stun-Gun Wristwatch"). Among the Detective Boys, Rumi shows special interest in Conan for unknown reasons. In the old warehouse case, Rumi was only paying attention to Conan and purposely used clumsiness in order to give Conan the necessary hints to solve the case. When a murder case occurred in her apartment, Conan found a receipt that has that day's morning and noticed she had bought additional plates and mugs. Conan eventually realized the reason behind his sensei's actions. Rumi sensed a murder might occur in her apartment and was from the very beginning planning to invite the Detective Boys, especially Conan so he would become involved in the case. It seems Rumi is somehow testing Conan's intelligence and skills for unknown reasons.
Rumi at one point seems to trigger Haibara's skill at detecting Black Organization members, but Ai Haibara later tells Conan that she likes Rumi and wants to hear nothing bad said about her. Conan becomes increasingly distrustful of Rumi as time goes on, being reluctant to use his tranquillizer dart in front of her. So in one case, he leads Yamamura, who is to play the role of the sleeping detective here, to a tree to try to evade Rumi's scrutiny. Regardless, she still sees him use the tranquillizer dart on Yamamura and smirks. At one point, Conan notices Rumi pressing down on her right eye and seems to connect it to an eye disorder. Conan sees Rumi throwing away the 4-leaf clover Ayumi gave her and appears angry at her for it. Later, Rumi demonstrated a concerning level of apathy towards the Detective Boys. She allowed them to be thrown in harm's way by letting their teacher, Sumiko, be bait by exchanging umbrellas, allowing her to snipe the Black Organization back.
Rumi has an interest in Ai Haibara since she says she resembles the woman (Ai's mother) who ruined her.[](#cite_note-3)
### Sumiko Kobayashi[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=31 "Edit section: Sumiko Kobayashi")]
[Sumiko Kobayashi](/wiki/Sumiko_Kobayashi "Sumiko Kobayashi") is her junior superior as homeroom teacher.
However, in order to distract Chianti and Korn, she deliberately broke the umbrella and exposed Kobayashi to danger, so that she could take the opportunity to attack. This act is similar to "gambit" in chess, and was praised by Rum.
### Ryujiro Uematsu[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=32 "Edit section: Ryujiro Uematsu")]
[Ryujiro Uematsu](/wiki/Ryujiro_Uematsu "Ryujiro Uematsu") is the headmaster of her new school.
### Hyoue Kuroda[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=33 "Edit section: Hyoue Kuroda")]
[Hyoue Kuroda](/wiki/Hyoue_Kuroda "Hyoue Kuroda") seems to have some knowledge about her. When he heard that she went camping with the Detective Boys, he comments that camping was something that she wouldn't do. Kuroda suspects it is possible that she thinks him as the murderer who killed Amanda and Haneda, because there was hostility in her eyes. However, it is more likely that she blames Kuroda for not saving them in time.
### Kohji Haneda[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=34 "Edit section: Kohji Haneda")]
Rumi Wakasa/Rachel Asaka first met Kohji when she accompanied Amanda [seventeen years ago](/wiki/Case_from_17_years_ago "Case from 17 years ago"). Kohji said she is his ideal girlfriend while she thought of him as a "foolish person" because he sacrificed himself to protect her from the Black Organization. She keeps Kohji's good luck charm, the shogi bishop, which was handed by him and has memories of Kohji hiding her in his bookshelf. His last words were "Huh? Why did I help you? I decided to do so. I must carry my initial dream through to the end" still ring in her head as she seeks revenge for both Amanda and Kohji's murders.
### Tsutomu Akai[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=35 "Edit section: Tsutomu Akai")]
As of now, it is unclear what the relationship Tsutomu and Rumi had. During the beach house murder case, where after Subaru fends off a criminal gang and tells her to bring the Detective Boys to safety, she has a flashback of Tsutomu defending her, saying "The monster we are about to witness, is not an opponent a young girl should risk her life against, I alone will be enough". It is left ambiguous what the 'monster' that Tsutomu was referring to is.
## Name origin[[edit](/wiki/index.php?title=Rumi_Wakasa&action=edit&section=36 "Edit section: Name origin")]
[Gosho Aoyama](/wiki/Gosho_Aoyama "Gosho Aoyama") claims to have named Rumi after [Rumiko Takahashi](http://en.wikipedia.org/wiki/Rumiko_Takahashi "wikipedia:Rumiko Takahashi"), the author of the manga *[Urusei Yatsura](http://en.wikipedia.org/wiki/Urusei_Yatsura "wikipedia:Urusei Yatsura")*, whom heroine [Lum Invader](http://en.wikipedia.org/wiki/Lum_Invader "wikipedia:Lum Invader") is performed by her voice actress in the anime.
