Mikoto

Mikoto is a kunoichi and an apprentice carpenter who is obsessed with Rin (Mikoto is so far the only girl identified as not developing any feelings for Ikuto) and always attempts to peek at or touch her body, particularly when she is bathing. She is often jealous of Ikuto to the point that she would either threaten to hurt him or outright throw shurikens and/or heavy objects at him, but in response Rin will often make short work of her. Her family, of which she is the youngest human member, consists entirely of practitioners of Ninpo and Bushido.
