Erm, why seiza?

Unless I talk to you, don't open your mouth, okay?

Well then... First off, why have you come here?

Me?

I have come to join hastenly for violent battles. "くんずほぐれつ" means literally "violently pulling back and forward", and it was used to mean literal fights, but it just so happens that it is used primarly in context of sex nowadays.

I'm leaving the rest to...you... Can also mean "I'm leaving the rear to you".
