Shuichi Saihara

Shuichi Saihara (最原 終一 Saihara Shūichi) is a character featured in Danganronpa V3: Killing Harmony and a participant of the New Killing School Life.

Shuichi has the title Ultimate Detective (超高校級の「探偵」 chō kōkō kyū no “tantei” lit. Super High School Level Detective), which is the same title as Kyoko Kirigiri from Danganronpa: Trigger Happy Havoc.

Appearance
Shuichi appears to wear a black cap with a white strap most of the time. Underneath, he has has short black hair with a small ahoge. He appears to have very pale skin and thick, feminine eyelashes. His eyes are gambogeish grey.

Shuichi wears his high school uniform, which appears to be in a black uniform with five buttons on his right, another two buttons on his left and attached with his high school's logo. His pants along with his shoes seem to be in black as same as his uniform and his cap's color.

Personality
Shuichi appears to have a calm, serious and polite personality. However, he is also abnormally timid when it comes to speaking. He tends to blush shyly every time others compliment him. Among the sixteen students, he is a boy who stands out for his submissiveness and for his good sense. Even though he is timid, when it comes to acting and deducting he is wonderful enough to deserve being the Ultimate Detective, even if he thinks otherwise.

Even though he is a very skilled detective with superior ability and insight, Shuichi lacks self-confidence, as he claims he hasn't accomplished enough to be called a famous detective. He also feels he doesn't deserve his Ultimate title because he only happened to solve murder cases by chance, although Kaede Akamatsu says she doesn't believe something like this is possible.

Ultimate Detective
Shuichi is a very skilled detective, capable of solving murder cases faster than the police, although he claims he only managed to solve these cases by chance. However, Kokichi Oma's secret society is so mysterious that even Shuichi does not seem to know any organization matching up with it.

Danganronpa V3: Killing Harmony
Shuichi learned how to be a detective by watching his uncle and working as his assistant. Most of the cases that happened to come to his uncle were small things like investigating infidelity, but on the rare occasion when a murder case came up, he solved it faster than the police. He was recognized as the Ultimate, but he doesn't believe he deserves the title because he only happened to solve the murder cases by chance.

Demo - Class Trial ver.
Shuichi first seen at the end of the hallway and shyly introduced himself as the Ultimate Detective to Kaede Akamatsu. He admitted that he doesn't deserve that title. After the murder of Yasuhiro Hagakure occured, he was seen inside the cafetaria, investigating where the murder weapon originated.

Uncle
Shuichi is apparently very close with his uncle, as he learned to be a detective by watching his example and working as his assistant.

Kaede Akamatsu
Shuichi seems to strongly believe in Kaede, reassuring her and telling her that "if it's her, she can do it". His presence appears to comfort Kaede, due to his status as a detective, although she admits that he seems unreliable. She attempts to help raise Shuichi's confidence by giving him pep talks. However, Shuichi admitted to not completely trusting Kaede when murders occur, which disappoints her, although she does accept this since she believes he can solve the case.
