Masumi Sera (世良 真純 ,Sera Masumi) is a self-proclaimed high school detective and practitioner of the martial art Jeet Kune Do. After making an mostly correct deduction during a murder case, she transfers to Ran's high school class. She seems to know that Conan is a detective.

Background

Sera is a high school detective and skilled at Jeet Kune Do, a type of martial arts. She transfers in Ran and Sonoko's class at Teitan High. Since three years ago, she'd been living in America with her parents. She claims she'd rather live in Japan where she was born and raised, so she came to Tokyo and is currently living in a hotel.

Appearance

Sera transfers to Teitan High School.

At first, she wears a fedora and a dark jacket which gives her an androgynous appearance. When she transfers to Teitan High, she gets rid of her fedora and wears appropriate female clothing. Her hair is dark, wavy, and short; it doesn't even touch her shoulders. Addition to that, Sera has small breasts complimented by Sonoko.

Personality

Sera has a friendly and quirky personality. She fails to correct Sonoko's impression that she is a man and even makes it worse by declaring that Ran is "his type". She seems to be prone to dramatics like most detectives are, but perhaps to a lesser degree than Shinichi or Hattori as she bluntly says who the criminal is without preamble. Although she has crime scene experience, Sera seems to be less skilled as a detective than Conan, apparently missing a critical clue that was necessary to understand how the murderer's setup worked (although it is down to interpretation whether she made this mistake on purpose or not). Her catchphrase may be "case closed".

Plot overview

Sera's Introduction (Manga 768-770)

Sera first met Sonoko, Ran, and Conan on a bus after she was mistaken for a groper. After Sonoko declared Sera was the groper, Sera and Ran got into a fight, with Sera's Jeet Kune Do holding even against Ran's karate. Conan and Sera cleared up the misunderstanding by pointing out the real groper. Sonoko then mistook Sera for a boy, an impression which wasn't helped by Sera declaring that Ran was "his type". Sera and Ran both discovered they were heading to the same hotel, about which Conan is less than pleased.

Sera finds out the hotel she is staying at doesn't have a room available and complains at the front desk. A man then falls into the parking lot and dies. Conan runs to the source of screaming while Sera told the guard to watch the elevators before running to the roof. She immediately declares the crime to be a murder, giving her reasoning. She then reveals her name, Sera, that she is a detective, and knows Conan is a detective as well.

Megure is not pleased to have another High School Detective underfoot but lets Sera and Conan investigate regardless. After listening to the suspect testimony, police observations, and examining the crime scene, Sera announces that she has solved the case.

However, Sera's deduction leaves out a critical detail; Conan is therefore forced to use Shinichi's phone to call his own, give Inspector Megure Conan's phone, and speak through Shinichi's as Shinichi using the voice-changer bow tie. Shinichi figures out the detail that had Sera stumped, although a look she gives Conan as he runs off suggests her omission was possibly intentional, and once during the phone conversation she tries to trick Shinichi into admitting that he is physically present at the crime scene instead of being explained the details by Conan and Megure.

The other day, Sera transfers to Teitan high school, surprising both Ran and Sonoko. She was rather popular at school surrounded by students asking her questions about herself.

Kogoro Detective Agency Hostage Crisis (Manga 771)

She sneaks behind Sonoko and Ran after school and says she wanted to visit Ran's apartment after knowing Conan currently lives there. Unfortunately, Conan and the rest of detective boys were staying at Agasa's house, having things ready for camping the following day. When the bomber pulls out his gun, Sera speaks to Ran telling her to go for the gun. Sera's speed surpassed the Bomber's vision and she managed to leg sweep the bomber onto the floor. After revealing the bombs on his chest, Conan calls Ran's Cellphone. Sera takes the phone and says Hi to Conan, and faked turning off the phone so Conan can hear the conversation .

Speculation

Sera mentioning Conan's name.

Sera knew Conan and Ran's identities before they introduced themselves. Although she claimed to know Ran from Karate tournaments, she additionally recognized Conan as a detective. This may indicate Sera has done research or follows stories about Conan's achievements or that she has had direct or indirect contact with Conan and Ran. However, Ran and Conan didn't recognize Sera. Sera might be one of Ran's martial arts rivals, although Ran, did not recognize her.

Shuichi Akai's younger sister

Sera and Shuuichi Akai.

Sera might be the younger sister of Shuichi Akai. Sera has bags under her eyes identical to Shuichi Akai's. Also, Sera Masumi's name is also incredibly similar to Mobile Suit Gundam character Sayla Mass (セイラ・マス, Seira Masu). Akai's name is derived from Sayla Mass's older brother's name, Char Anzable. Also, Conan said he has a feeling he had met her before.

“	Somehow I feel like we've met her before, it might be that person resembles someone I know, that's why the feeling that we've met before is on my mind...	„

Sera lived in Japan until three years ago when her family moved to America. This matches with the time when Akai was infiltrating the Organization. The family's move to America could be the FBI's attempt to protect them should something go wrong with Akai's mission.

Bourbon

Another possibility is that Sera could be Bourbon from the Black Organization, though that is starting to look unlikely due to the fact that Bourbon is thought to be a male while Sera is a female, as well as the fact that she is at Ran and Sonoko's age.
