Yurine Hanazono, a gothic-looking girl, summoned Jashin-chan, a demon. Jashin-chan resorts to violence to free herself from her earthly chains after being unable to return home since the required spell was not included in the summoning grimoire. This is easier said than done, though, for Yurine is no wimp. She possesses enormous physical prowess, which she used to slaughter Jashin-chan in a number of ways, including putting her arm in a blender, spreading her guts throughout the room, and even frying her. Though these acts would be devastating to anybody without the capacity to regenerate, Jashin-chan isn't entirely unjustified. Because they are stuck together, Yurine allows Jashin-chan live with her in exchange for labor around the house.
