Mary sue is a character that can do no wrong not just an extremely strong power level wise character you fucking retard.
Alice has a lot of negative personality traits. She literally yeeted hilichurls off cliffs just to experiment on them.
A mary sue is supposed to be perfect in everyway and forced to be liked by everyone but Yae Miko doesn't even like Alice and you can probably find other examples like this if you just fucking read anything in the game or wiki.
