Ryoma Hoshi is a character from the Danganronpa V3: Killing Harmony video game.
A world-famous tennis player. During international matches, he would kill mafiosi by hitting them in the head with a custom-made steel tennis ball, earning him the nickname "Killer Tennis" and the death sentence. He has a jaded, hardboiled demeanor despite being a teenager, and claims that the Ultimate Tennis Player is already dead due to already being in jail before coming to the Gifted Inmates Academy.
He is the victim of Chapter 2, allowing himself to be drowned by Kirumi Tojo after learning that nobody outside the killing game cared about him, and he had no one outside the academy to live for.
In the XP4 fics, Ryoma is brought back to life. Ryoma is a member of the Heroes Coalitions as a trainee. He also attends the Vanguard Academy as a student.
Ryoma is the shortest character in Danganronpa V3. Contrary to his soft appearance, he has a very deep voice. He has cropped red hair, black eyes with no visible pupils, and rosy cheeks.
He wears a black hat with two points that has a picture of two blue tennis rackets on it, a black leather jacket, and a black and dark blue striped jumpsuit underneath, similar to that of a prisoner. He wears brown shoes and has a metal cuff attached to his left leg with a bit of a chain attached to it.
His legs are notably much more muscular than the rest of his body. He always has a candy in his mouth, which may give the impression of a cigarette.
Before gaining his Ultimate talent, he wore a standard school uniform, with a gray blazer over top a white dress shirt and red tie. He also wore black pants with a plaid pattern and black loafers. Interestingly, he still carries a candy cigarette in his mouth.
Ryoma is a hard-boiled dandy character. Though he looks like a child, it's been said that his life experience would put an adult to shame. He has a coolness that common high school students don't have, heightened by his very deep, mature voice. He is the calmest, composed, and an unperturbed person in the Killing Game. He isn't shaken by murders nor even if he is personally harmed. He often mentions how he refuses to do something "uncool" and doesn't want to show his softer side.
After killing a mafia organization with his own hands, Ryoma considers himself a killer, the kind of person other people should not get close to. While generally not appearing very aggressive, he is apparently willing to harm and even kill people if he believes they deserve it, and he occasionally gives others a very piercing look as a warning.
Ryoma has a tendency to push other people away. He feels others shouldn't get close to him, because along with being a murderer he is on a death row and thus likely to die soon, which would cause his close ones emotional burden. However, his younger self was a big animal lover with a positive and proactive nature, but he states that he is now just a shadow of his former self and his old self no longer exists. Nevertheless, he still has certain kindness in him and retains his great love for animals. He will not stand seeing an animal in trouble, considering such situation an emergency. He also empathizes with Kaede's wish to escape and become friends with everyone, considering it "not bad" of an option. Despite being depressed himself and warning Kaede to not be so idealistic, his kindness often shines through and he occasionally gives other people good and positive advice, showing that he still has faith in life and positive thoughts deep down. During Class Trials, he generally trusts others but doesn't hesitate to voice his doubts and use calm judgment. He is also willing to immediately apologize for incorrect doubts. Furthermore, Ryoma is still interested in tennis even though he strongly denies this at first.
Due to his past, Ryoma appears to be depressed and suicidal, assuming he has very little time left and is unable to have any close ones. He has little regard, if any at all, for his own life. He believes that being a death row inmate automatically makes his life worth less than anyone and he is very much willing to die for the sake of the other students. In Chapter 1, he offers to have one of the others kill him so that they may escape the school, allowing everyone to continue on with the Killing Game. Rantaro manages to convince him otherwise, but he is still in a lot of doubt. He decided to look for a reason to live but became even more suicidal after his motive video revealed that he apparently has nobody to care about him in the outside world, causing him to find no reason to live. However, the situation is a bit unclear, as he showed a more positive change in attitude while talking with Shuichi. While Kirumi claimed that Ryoma had accepted his fate and wanted her to kill him, this is never confirmed and he had tried to fight back against Kirumi in order to live. In the non-canon bonus mode of Danganronpa V3, Ultimate Talent Development Plan, he also grows a bit more positive during the three years, as in the end he thinks that his future didn't completely disappear a long time ago after all.
Ryoma has mentioned that he doesn't feel anything anymore concerning sexual matters, supposedly due to his depression. Such situations also make him uncomfortable, presumably because he suffered from harassment while he was in prison.
Ryoma was a tennis player with a promising future, world famous since his middle school days and winning many international matches. He is able to use the Shukuchi Method, a type of rapid movement that takes advantage of the opponent's blind spot. He would always enter the tennis court using his right foot, which he felt gave him good luck.
The Mastermind's claim that Ryoma's talent as the Ultimate Tennis Pro is a fabrication made by Team Danganronpa. Due to that fact, it is unclear whether Ryoma is a tennis champion in the past.
