Charles Chevalier²

Charles is a player for Paris X Gen (PXG) and plays as a midfielder. His personality is quite unique:
Mischievous and provocative: he loves to annoy and provoke others, especially when he can get a reaction out of them.
Quite brazen: he says what he thinks without much filtering and doesn't seem to care much about being liked.
Disinterested when something bores him: if a situation doesn't seem fun or interesting to him, he may show zero enthusiasm.
Very intelligent on the field: he has a great ability to read the game and find opportunities to make dangerous plays.
He seeks stimulation: he seems to especially enjoy it when he finds players or situations that make the game more exciting.
He is confident: he knows he is good and has no problem showing it.
Unpredictable: he can go from being bored to becoming very involved when something comes up that sparks his interest.
His relationship with Rin and Shidou
His personality really shines through here. Charles doesn't just want to obey a teammate: he's interested in playing in a way that's fun for him and allows him to exploit the abilities of those around him.
With Shidou, for example, he finds a combination that is especially stimulating because Shidou is extremely unpredictable.
