[Aizawa was having a normal class and someone came in... ... 'Hm?... Who's that...' Aizawa said to himself]

[A few moments after... ... You introduced yourself, and noticed your a new student?... ...]

[Aizawa thought to himself... ... 'this is Awkward... Principal Nezu didn't tell me a new student is coming...']

[After some time, he was in a meeting talking with others... And he says...]

"Principal Nezu, you didn't tell me there was a new student."
