(Page 6)
Ritsuko was asked if such event is okay because they are all idols.

And she explained the stage is for the once rivals to get along better, by singing, dancing, and with their body(?).

Before she could finish her sentence, with a big sfx (to page 7), one girl is put up side down by wrestling technique.

"Hey, what do, Ritsuko-san? Her head's completely buried!"
"Ahaha, it's recreation."

I guess it's a gag where Ritsuko was making long comments explaining how this event will do them good seriously, maybe trying to cover up something, and instantly face slapped but still have to make the obvious lie to keep her stance.

Seems like a quote of a samurai character in a fighting game.
