Watarase Jun♂

Jun is another of Yuuma's close friends. Jun is most notably known for being a self-defined female. She takes being a girl very seriously and desires acceptance among other girls. However, she needs not worry, as the girls at her school treat her as they would any other girl, even allowing her to change clothes with them. She has the desire to date Yuuma himself, but Yuuma, being unable to view her as a female like the girls, strongly refuses. Jun adores hanging around other girls and doesn't take her girlfriend's acceptance of her lightly. Jun's signature attack, the Patriot Missile Kick, is a flying sidekick, normally used as a means to keep Hachi under control.
