The narrator, a black-haired girl who controls almost everything in Shōji's daily life including housing layout, food, clothes, and outings. She is cautious like when they first met, always alert while sleeping, but can also be careless and trusting. She is excited about New Year rituals and costume designs for Kobayashi Sachiko. She drinks fruit wine and gets slightly tipsy. She calls Nakahara Chūya brother and feels flattered when he calls her sister while drunk.
