Well, not quite. I'd hoped for an item or term associated with badminton (as opposed to the word "badminton" itself) that Remilia could legitimately mispronounce as "squid".
A game of punishment badminton is it? Just be glad it's the Weakly Disgusting sisters. I wouldn't want to see how Flandre normally "punishes".
Hanetsuki?!So then that probably means...They say the winner is the one who puts ink on you.Splatters? You mean paddles?I wonder how you play it.Ah!Yep, hanetsuki!They say playing a game with splatters is popular now.Originally, ika (squid) vs. ita (plank/paddle)Oh yeah, maybe it was paddles.
