Ryoma Hoshi

Ryoma Hoshi (星 竜馬 Hoshi Ryōma) is a character featured in Danganronpa V3: Killing Harmony and a participant of the New Killing School Life.

His title is Ultimate Tennis Player (超高校級の「テニス選手」 chō kōkō kyū no "tenisu senshu"). Despite his promising career, he killed a whole mafia organization and became a prisoner on death row before being shut in Gifted Inmates Academy, earning him the nickname Killer Tennis.

Appearance
Ryoma is the shortest character in Danganronpa V3. Despite his appearance, he has a very deep voice. He has black eyes with no visible pupils and pale rosy cheeks.

He wears a black hat with two points that has a picture of two blue tennis rackets on it. He wears 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 the cuff.

His legs are notably much more muscular than the rest of his body.

Personality
Ryoma has a coolness that common high school students doesn't have, heightened by his very deep, mature voice. He is very calm and unperturbed, even when being forced into a killing game. He isn't shaken even if he is personally harmed.

Though he looks like a child, his life experience would put an adult to shame. Due to his grand past as an assassin, he considers himself a killer, the kind of person other people should not get close to. He isn't bothered by murders and in the bonus mode of Danganronpa V3, he is very amused by the idea of "crushing" Nagito Komaeda.

Apparently, younger Ryoma had a positive and proactive nature, but now he is just a shadow of his former self.

Danganronpa V3: Killing Harmony
Ryoma was a tennis player with a promising future, world famous since middle school days and winning many international matches. However, because of unknown reasons, he began to kill mafia members by hitting them in the head with his custom-made steel tennis ball. The entire organization was annihilated and as a result he earned the alias Killer Tennis and ended up a prisoner on death row. Because he was incarcerated before coming to Gifted Inmates Academy, he says that the Ultimate Tennis Player already is no more.
