Need all 5 of them to go at Mei at once and watch her utterly combust. C'mon strategize here! Don't do the classic fight mistake of going in one at a time!
"Kissing is for after marriage" while not toxic, doesn't exactly strike me as healthy either. I mean, I guess it's not unhealthy, but that's not something I'd be into.
Anyways, I have no problem with Karin. She's at least honest about everything. She might be poly or into open relationships, but she wouldn't cheat because she doesn't lie.
Oh, so the colours weren't only for show, heh? And yes, it's thanks to too-many-legs that yuri strikes when the guard is down. You must be ready anytime, Mei!
