PISS EDIT: Chapters without someone peeing themselves: 0
Wow is that it for Ken-chan? It was indead manly of him but I feel disappointed...
And serious discussion here, usually the mangaka likes to repeat the last scene of previous chapters as the opening pages for a new one. Yuki pissed herself at the end of chapter 283, and then chapter 284 is just a repeat scene, does the piss counter reset again? Or does the count go up? IMO, I think repeat scenes don't count.
