class 1-a takes a trip to the us or britain or some other english-speaking country. some of them struggle to speak, some get a conversation going, some can only read the signs. they all, however, recognize the fact that when aizawa-sensei speaks they have no idea what fucking language he’s speaking in
“sensei, what language is that?” midoriya asks, always curious.
