I feel like Aizawa would see Eri and kinda be reminded of himself. How he was stuck in the business at a young age. I feel like that he has alot of rage towards people who recruit children.

That’s exactly why he’s so protective over kids! Since he went into the business so young (at age 10) he knows just how hard and brutal it can be. Every time he sees a child affected by the business, whether it be by being in it or losing something to it, he’s reminded of himself and it makes him both sad and angry enough to curse whoever made a system so cruel.

So far, the only gangs to regularly recruit anyone under 16 are Shigaraki, Chisaki, and Yaorashi.
