A shinigami trying to kill a girl keeps turning into an angel because people around her won't stop being nice. The premise is absurd, but the show uses it to ask something real: what happens when the force of someone's kindness literally rewires you against yourself? The soundtrack doesn't just underscore these moments, it becomes the language the show uses to say what the characters can't, especially in an ending theme that sits with you long after the final episode.
Risky is a junior shinigami with one job: claim Moe's soul. There's just one catastrophic problem. A magical binding links Risky to Safety, an overeager apprentice angel, and whenever someone says something genuinely kind or encouraging, Risky transforms into Safety against their will. Safety's whole purpose is cheering people up and spreading positivity, which makes Risky's mission nearly impossible. Shinigami can only harvest souls from the deeply depressed, and Safety keeps ruining that by being insufferably supportive. What follows is a constant clash of purpose. Risky schemes to isolate Moe and cultivate despair while Safety sabotages these plans with genuine encouragement and friendship. The two celestial beings trapped in one body become locked in an endless struggle over Moe's emotional state, forcing Risky to get creative about death-taking while contending with an angel who won't stop believing in the human spirit. It's comedy built on a simple premise pushed to absurd extremes: what happens when you pair death incarnate with hope itself and make them share a body.
