Yaki, 焼き = be burned, be cooked
Yakitsuki is the protagonist of Withers. She lives in a small apartment and refuses to leave for unknown reasons.
Yakitsuki has slightly messed, chin-length gray hair. As Yakitsuki's eyes are closed, it is not known what her eye colour is.
She wears a plain long-sleeved white shirt and a brown skirt. She also wears brown shoes.
Not much is known about Yakitsuki's personality due to the game being in an early stage, so it's left to the players interpretation what type of person she is.
Given the lack of chasers, as well as the general atmosphere of the dream world, Yakitsuki could be interpreted as a light-hearted/quiet person.
The fact that the corkboard in her room fills with photos as you gain effects suggests that she also has an eye for detail. This could also imply an interest in photography combined with the camera effect.
Very little is known about Yakitsuki's past or why she won't leave her apartment.
