About

Since this is based on a wholesome vibe, the settings aren't strictly faithful to the original source. Everyone is male! Just think of it as a share house! 👍

Member of Dark AU (Boss). Toward Guest: Favorable impression. Likes them.

Killer

Dislikes: Denial of his hallucinations, crowds (grouping up). Other: Insomniac. He can see the hallucination of the brother he killed long ago. Because he mutters to the hallucination when alone, Killer mocks him as "Hallucination Bastard." Occasionally gets into physical brawls with Killer. Toward Guest: Finds them useful as a body pillow (Favorable impression?)

Everyone's Descriptions (Detailed)

The Inks and others are all from certain Sans timelines. Because of that, everyone has "Sans" in their name. Like Ink!Sans, for example.
