So.. If you when a chuuren poutou you'll die? What kind of mahjong superstition is that?
Tried searching around the interwebs and didnt see anything, maybe its just a Sakiverse thing or because chuuren potou means Nine Gates and may allude to something like the "nine gates of hell". The lanterns behind Teru might also refer to something in the netherworld , just maybe.
Yeah. I tried too but all I got is about a book and a movie. Tried searching Nine Lanterns, but according to chinese myths/symbolism it's more goodluck than a bad omen so maybe it really is an original idea from Ritz sensei.
