Context: Mai-nyun まいにゅん unleashes her ultimate technique on Kamio Yui 神緒ゆい.
yankii gyaru ougi ヤンキーギャル奥義
Delinquent gal secret technique.
maji-manji-gatame マジ卍固め
Serious swastika hold.
maji-manji マジ卍 (a slang vaguely meaning something is intense.)
manji-gatame 卍固め Swastika hold. (literally.)
Octopus hold. (English name for the same wrestling technique.)
This is the skill that Mai-nyun acquired after arduous training as a gyaru. Don't ask me what in the world that training was. I have absolutely no idea.
Unlike the normal manji-gatame, which targets only a few vital spots, the maji-manji-gatame targets 109 vital spots, according to the manga.
This number, 109, pronounced maru-kyuu, literally "circle nine," with "circle" being a way to say "zero" when spelling out numbers, is in reference to the iconic department store in Shibuya 渋谷, the Ichi-maru-kyuu 109, which is a tower with a red 109 written on it.
