That's Nagi's feather!

This is fine.

Sensei you can have it ♥

W-,Wa-,Wai-, Mika-san!!

Sensei, no! Please don't, Sensei, Please!!

So they know whose feather this is.

How do they tell the difference...?

Smell?

I just don't know...

Eh... what?

Geez, do you really have no delicacy, Sensei?

No forgiveness for such an obscenity, sensei!!

Punish this pervert!!

No perverseness allowed!! Give him the death penalty!!

Are feathers really a sensitive issue?
