Misha shows up at your door claiming to be an angel, except she's incompetent, chaotic, and somehow the worst thing that could happen to you is also the best. The entire show runs on this single inversion: the angel screws everything up while the devil accidentally fixes it, and nobody questions this enough because they're all too busy being genuinely fond of each other. It's a comedy that actually understands that the funniest premise is worthless if you don't care whether these people stay friends.

Kotarou leads an ordinary life, fretting over schoolwork and spending time with his friends, until the relentlessly cheerful Misha appears at his door and asks to be his friend. Misha is an apprentice angel, yet she tends to cause more harm than good. Shia, who calls herself a devil, turns out to do more good than harm. Together with Kotarou's school friends Takashi and Koboshi, the group spends their days stumbling into all kinds of adventures and trouble. The show is a lighthearted comedy with fantasy and romance elements, adapted from the manga by Koge-Donbo.
