Leon's wikipedia page: https://danganronpa.fandom.com/wiki/Leon_Kuwata

As described by the wiki, "Leon Kuwata (桑田 怜恩) is a student in Hope's Peak Academy's Class 78th, and a participant of the Killing School Life featured in Danganronpa: Trigger Happy Havoc. His title is the Ultimate Baseball Star (超高校級の「野球選手」lit. Super High School Level Baseball Player). However, he states he wishes to change his title to the Ultimate Musician (超高校級の「ミュージシャン」lit. Super High School Level Musician). 

Leon is a passionate, hot-blooded young teenager. He often slacked off from studying and baseball practice; however, his baseball skills were never diminished due to his status as Ultimate Baseball Star. In fact, he hated practice, seeing no point or enjoyment in it because he was already so talented. Due to his natural physical talent, he considered even very difficult and unusual feats easy and had some trouble empathizing with people who lacked such talent, as he didn't fully realize how hard the bet he made with Kanon really was.

Despite his talent, Leon claimed he strongly hated baseball and was very determined to change his current title to Ultimate Musician. He had a tendency to complain about the several things he found uncool and gross about baseball, often without any prompting from others. He was quite arrogant, often talking about his popularity and dreams of being even more famous, considering himself a 'future superstar'. However, during his Free Time sequence, he implied he wasn't actually very good at being a musician and the reason he wanted to become one is to win a heart of a girl he happened to meet at the hair salon. He claimed that being popular is the whole point of being a musician, and once briefly thought about being an actor instead if that's what Sayaka is more into, generally appearing a bit confused about his own motivations and feelings for the matter. Furthermore, he was quite bitter about how people constantly forced him to play baseball and follow the sport's traditions due to his natural talent, with his completely new goal and look appearing to be at least partially a form of rebellion.

However, in reality, Leon grew to miss baseball after not playing for awhile, since he used to do it every day since he was young and it actually made him feel good. He reluctantly admitted this to Makoto during his Free Time in School Mode, as he needed someone else along with him to properly play. With all his talk about hating baseball, he was embarrassed to admit how he really felt, and accused baseball of brainwashing him. He considered returning to his old team, though he still absolutely hated the idea of practicing. During his School Mode ending, he decided he would both play baseball and sing, to become 'the ex-baseball star who's a totally famous singer now' later in life. He liked the idea of an all-new approach that is just for him, showing that he just disliked repetitiveness and other people deciding things for him."
