My Roommate is a Cat Wiki

Haru Mikazuki[2] is the deuteragonist of My Roommate is a Cat. She is a stray tuxedo cat who was adopted by Subaru Mikazuki where her life prior to being adopted was rough; she struggled to feed herself and her four siblings, one of whom died. She and Subaru rarely understand each other, but their misunderstandings lead to a common goal. Part of the story is shown from her point of view. She initially believes that her name is a sign for food as that's the name of the girl who once gave her food.


Haru is a cat that has black fur with a white triangle over her eyes and mouth. She wears a 13-19 cm red Meowal collar with a red ribbon attached, it formerly had a bell which Subaru removed since it annoyed him.[3]


Having grown up as a stray struggling to survive, Haru has been shown to be insecure and cautious of those around her. This distrust extends especially towards humans, who mistreated her and her siblings on the streets.
