Onizuka Hime

Japanese name:	鬼塚一愛
Nickname:	Himeko, Onihime

Hime Onizuka is the "Amazon", or "Yankee" (combat specialist) of the team - a volatile and highly dangerous close-range fighter who serves as the Sket Dan's muscle using her specialized field-hockey stick 'Cyclone'. Already a formidable antagonist, with this innocuous-seeming weapon in hand she is easily capable of defeating multiple opponents instantaneously or shredding a full-grown tree in moments .
