Like Yuumi and Saki, Maika becomes obsessed with Subaru after they have sex. Even before they had sex, she had developed feelings because he was the only person who saved her from her bullies. She made lunches for him on the off chance that he wanted to eat lunch with her. Once she learns where he lives, she frequently breaks into his house to rearrange his furniture and to try and have sex with him. She doesn't like seeing Subaru with other girls, but she doesn't do anything other than voice her disapproval. She once cut herself when she witnessed Subaru having sex with Saki.
