Rin Onigawara

Rin Onigawara is one of the main characters from the Armed Girl's Machiavellism anime and manga.

Rin is the first of the Supreme Five Swords that Nomura meets by means of being in the same homeroom. Never seen in public without her mask for reasons unknown. She is a practitioner of the "Kashima Shiden Jikishinkage Ryu".

In the AWA fics, Rin is set to debut in a future AWA storyline.

In the XP4 fics, Rin debuted in the XP4 Heroes Coalition - Mission Chronicles.

Rin has a fair skin, a short black hair in a traditional bobcut and has purple eyes with a half demon mask covering her right eyes. She wears a black long-sleeved sailor uniform with a white collar and a red neckerchief with a belt and a rope wrapped around her waist, black miniskirt, black high socks with a white garter and brown shoes.

She was famous for her prominent and irrational hate of men. She is also merciless until most transfer students quit school. Thanks to that, her class always has less people compared to the other classes.

As the series progresses, she starts to hold feelings for Nomura after he defies her rules and beats her in battle before they accidentally kiss each other. This is further proven as she shows an emotional side to him and reveals her reason for wearing a mask is due to her mother scorning her after her father had an affair and abandoning them. Nomura calling her face pretty had made her happy and work up some strength to not wear the mask and is touched after he returns the mask and reveals his own tragic past.
