Nazo Koumori

Serving as a quirky narrator throughout the Rosario + Vampire II manga, this eccentric bat frequently interrupts the action to provide battle timelines or censor suggestive scenes. Though he functions as Shuzen Kokoa’s loyal servant, he possesses the remarkable power to transform into various melee weapons, despite his heavy 100kg weight. He is instantly recognizable by his signature habit of punctuating almost every observation or remark with a cheerful, high-pitched "weeee!"
