A girl materializes from a sacred tree Jin carved up for homework, immediately furious, immediately hilarious. The show's real weapon is how it weaponizes anime tropes themselves, every reference lands because the characters are already living inside the joke, not explaining it to you. Chemistry between Jin and Kannagi crackles because they're genuinely annoyed with each other, not performing romantic tension for a checklist. The animation moves like it cost twice what it did, fluid enough to make a gag about swatting bugs feel genuinely cinematic. It stumbles into an ending that feels like someone forgot to finish the thought, but by then you've already watched the same two characters bait each other through a dozen perfect comedic exchanges. This is what happens when a show knows exactly what it is for thirteen episodes and commits completely to it.

Middle schooler Jin Mikuriya carves a statue for a school project from the wood of a sacred tree. When he moves it outside, the sculpture touches the ground, draws in the earth around it and turns into a girl named Nagi. She is a Shinto spirit who guards the village, and she is angry that her sacred tree was cut down. With nowhere else to live, she moves in with Jin. Her powers are drained, so she cleanses the land of "impurities" with nothing but a magic wand, and Jin is expected to help. Squashing bugs is often how that cleansing works out. Nagi also has a rival, a younger sister guardian deity from a shrine across the river, who wakes up and sets out to become the village's top teen idol. The result is a supernatural comedy built on the daily antics of Jin and Nagi as their lives become intertwined.
