Rumia (Universe 13)

Rumia is a Demon, and the Universe-13 character of Scarfy

Bio
The creature calling itself Rumia is not quite a demon, but rather, one of the many 'evil' Shin-Jin that are sent to live with actual demons.

Of course, with little prospects inside, her status as one of the youngest in comparison to the many others within, already vying to be the next Makaioshin once the current one is gone, along with her childish appearance, leaves her no chance at 'advancement' within.

This led to her outright leaving, while theoretically hard, no one assumed what seemed to be a surprisingly innocent, if morbid, 'demon' out would cause too much trouble.

They were, mildly, correct. At most, she's the cause of a number of murders never quite found out, or missing livestock and the such.

Despite her ability to properly raze towns to the ground if she wanted, she seems to care none about such a thing. Rather, she merely eats any living beings she comes across. No care as to sentience, if anything, preferring humans for the ever-so-playful chase.
