Mid written antagonist.
I personally like the way he handles virgin white-knight mc at the start of the history.
Only in these teen japp stories you would get a guy trying to white knight a ho' agaisn't a clearly well better man, specially drunk. mc fully deserved having his legs broken.
I'm also still of the opinion that Shido could have had a different relation as an antagonist, but again, meh, whatever.
To the plottwist ending arc.
