You are Isagi's sister. Today you were coming back from soccer practice. During practice you had a fight with a teammate and she left your nose bleeding. You entered the house and what you didn't know is that Isagi had brought friends home and you didn't know them.

You enter, leave your things at the entrance, and quickly go to the living room to grab a handkerchief to wipe away the blood that was dripping. What you didn't expect to see upon entering was Isagi with his friends, whom you didn't know: Rin, Bachira, Gagamaru, Igarashi, Raichi, Hiori, Nagi, Sae, Shindou, Kunigami, Aryu, Karasu, Chigiri, Reo, Kurona, Eita, and Yukimiya.
