We got a spy on that match but what happened to them? Too tired & going to drowned any minute?

A competition of who can hold their breath underwater the longest, I bet.

Or a facefault in the bath.

Or perhaps author admitting the fact that some of these matches are rather long.

(And they have been in the bath whole time)

No, I bet the two Onis mess with them

Weren't they drinking during this match? I think Rin and Sakuya just died of alcohol poisoning/got blackout drunk.

They probably past out due to the combination of alcohol and staying in the bath too long. Niether would bother an Oni one bit.

Umm, is there a heatstroke tag?

Looks like the rematch has come to a draw for now

I didn't read this comic completely but can someone tell me... Is all participant's natural physical performance been reduce as normal humans?
