@maozli He put Kuon in a head lock, so what? In the real world, you'd get a red card if it happened on the pitch. You'd probably be fined by your team if it caused an issue in the dressing room. Shidou tried to axe kick Rin's brains out. In the real world, that's a straight up ban from football and you're probably arrested for attempted grievous bodily harm/murder.
Shidou is lucky he got away with being in the punishment room AND keeping his spot in Blue Lock (because Ego was still going to keep him in as a super sub). In real life, Shidou would be gone. To be fair, in real life, Shidou would've been gone back when he tried to axe kick Igaguri too. Or when he tried to roundhouse kick Isagi. Do you see the difference? Raichi can be aggressive sure (as can other players), but Shidou is a complete psycho and is literally lucky that Ego is crazy too, because any rational person would have kicked him to the curb by now.
