A guy with ogre blood in his veins just wants to keep his head down until his childhood crush moves in as a witch and everything becomes controlled chaos. The comedy lands because nobody's trying to be cool about any of it, Nico's magic constantly backfires, Morihito's stuck playing bodyguard for someone he can't say no to, and their shared apartment becomes the worst possible laboratory for both of them. It's the kind of show where the romance breathes because the characters are too busy laughing at how badly things go wrong to make it weird.

Morihito is descended from ogres, but he enjoys a quiet, ordinary life as a high school student. That changes when Nico, his childhood friend and a witch in training, comes back into his life and claims him as her familiar. Now he has to protect her from a disaster that has been foretold, while also coping with the unpredictable chaos her magic causes. Living under the same roof turns into a mix of awkwardness, supernatural mishaps and real threats. Nico is thrilled to be reunited with the boy she has a crush on, but Morihito takes his protective duties so seriously that romance faces an uphill climb. The result is a blend of comedy, romance and slice-of-life fantasy with a looming prophecy of doom beneath the lighthearted moments.
