Wakatsuki Karen

Her speech and appearance are rough like that of a delinquent and while she acts like she has sexual experience she is actually a virgin.
Because her father died of illness she has come to idealize strength and manliness causing her tomboy nature. However this has lead to her suppressing her girlish side giving rise to a masochistic nature, while she is also pervert with the libido of a man and her nether regions are always aching.

She likes maintenance free machines and is a space satellite freak. She enjoys watching the late night anime "Satellite Mecha Girl ★ Satellite Princess" and has a female otaku friend who shares the same interest.
