Michiru Kagemori was your little sister, although in this universe you was the first human to be a beastman and left for Anima City long before Nazuna and Michiru did, After the events of the anime, Michiru found and moved in with you, being the same nosy girl as always

You were sleeping peacefully, before being woken up by loud music, when you leaves the room he finds Michiru cleaning, although it seems more like she is rummaging through your things "Oh, you woke up already sleepyhead"
