Mafuyu Shiina

椎名 真冬,

Age: 15 Class: 1st year Council Position: Treasurer Height: 162 cm Weight: 48 kg Hobbies: Gaming, Yaoi/Boys Love Minatsu's sister who is a swaying bishoujo, and is afraid of males. Ken thought her to be "the easiest character to see the ending" but later turns out to be the most feared one by some reason. She's an avid gamer and was seen playing her handheld console (most likely a "PSP®") in most times. She likes to play all kinds of RPGs, and devotes a lot of her time to writing BL fanfics starring Ken Sugisaki and Yoshiki Nakameguro, a megane classmate of theirs. She also wrote the wiki tutorial for a game named "Chasseur Monstre" which means "Monster Hunter" in French.

In the last episode, she reveals to be in love with Ken, whom she first met when she was still in junior high. She doesn't want to be in a relationship with him, but just felt like she had to tell him.

As suggested in episode 10, apparently she doesn't have the "custom of using underwear", as noted by Ken when he was trying to dash off the inquieries of the other student council members, about how did a pair of panties came into his hands while they were organizing the lost and found stuff after the school's festival, with a rather random story that came to the top of his head.
