Here is a description of Reycho, via the game’s official website:
The unofficial leader of the Losers Class, no matter the problem, Reycho thinks hard about how it can be solved and will never give up.
He’s known for his physical ability, but occasionally runs into situations head first.
He’s childish in both good ways and bad, completely devoid of negativity, and is a pure and innocent child. However, he’s completely oblivious to girls.
