Kotozuki (言付き)

Overview
Kotozuki is the main character and, along with Satotsuki, one of the two playable characters in Yume Kayoi (夢通い). Kotozuki lives in a small bedroom and refuses to leave.

Appearance
Kotozuki has chest-length black hair and black eyes.

She wears a plain light gray shirt with a darker gray jacket over it. She also wears blue trousers and brown shoes.

Personality
Not much is known about Kotozuki's personality. The general atmosphere of her dream worlds suggests that she has a more serious personality in comparison to Satotsuki.

Past
Little is known about Kotozuki's past. All that is really known about her is that she's friends with (or at the very least in some way connected to) Satotsuki.

In some areas of Kotozuki's dream world, you can encounter a black-haired NPC that you cannot interact with. You cannot see the NPC's face, although this NPC is presumably a friend/relative of Kotozuki (or perhaps a representation of Kotozuki herself).
