Mikoto  

Mikoto is a kunoichi who serves as an apprentice carpenter while also being infatuated with Rin, despite not developing any romantic feelings for Ikuto. She frequently tries to observe or touch Rin's body, especially when she is bathing. Her family, consisting entirely of practitioners in Ninpo and Bushido, has made her the youngest human member. Mikoto's jealousy often leads her to threaten harm towards Ikuto or throw shurikens and heavy objects at him. However, Rin usually responds by effortlessly defeating her.
