You're reincarnated as a rib. Not a warrior, not a magical artifact, not even a sentient sword. A rib. The show knows exactly how stupid this is and commits so hard to the bit that you stop laughing at it and start laughing with it. Stop-motion, puppet theater, live-action sequences, each absurd reincarnation gets its own visual language, and the chaos of watching the Goddess and the protagonist spiral through increasingly unhinged premises is the entire point. This is what happens when a comedy refuses to let isekai tropes breathe, treating every "chosen one" cliché like a joke setup waiting to be demolished.

In a world where souls are free to pick their next form, a surge of applicants has pushed the queue for coveted roles like Demon King or a cheat-skilled hero with a harem to a wait of 50,000 years. The narrator, known only as "I," has no patience for that. Instead he reincarnates again and again into ever stranger forms, starting as the rib of an overpowered hero bound for a happy harem ending. Later turns see him as a hermit crab, a vegetable, and even an explosive meant for blowing up blissful couples, all under the eye of the detached Goddess who handles isekai reincarnations. The comedy fantasy mixes conventional animation with stop-motion, puppet theater and live-action footage to tell its string of absurd rebirths.
