It's a crossover/parody of Kaiji. In case you haven't seen it, Tonegawa loses to Kaiji and the chairman brings out a grill.
He explains that if you were truly regretful/sorry, you'd be able to bow anywhere; AKA: on that grill.
Ai (I think that's her name) is characterized in SZS as apologizing for everything.
I'm pretty sure that's what Kafuka's saying there, but I have no idea what Chiri is saying. The length of seconds has to be even?
