Oh, that's right, when you get mad you headbutt people. They were complaining about that earlier.

If they remember it well enough to complain, then all the better!

Keine-sensei's headbutts are famously painful. But, well, perhaps their bodies will remember better than their brains.

...I heard you used to be a teacher for Kaguya.

Yes, correct. Back on the Moon.

What'd you do when you needed to scold them?

Oh, you see, they were such good kids I never did. Kaguya especially. Well, of course there were some difficult ones too...

Ones who wouldn't understand no matter what you said. That being said, I'm not sure relying on headbutts is the best method...

Teaching is a constant learning process. There are many things you yourself can learn. Fufu

Hrrm... I wish I could get taught by Yagokoro-sensei...

Oh? I'll warn you, I can be quite Spartan myself.
