A girl literally powered by human happiness crashes into the real world to fix broken people, except the show treats it seriously while also being aggressively crude about it. The tonal whiplash sounds like a disaster on paper, but the commitment to both sides, the character design that makes Plug genuinely likable instead of just fanservice bait, and the willingness to actually develop people through her "recharging" makes it work in ways it has no right to. This is the kind of show that gets shelved and forgotten because nobody knows how to talk about it, but the people who find it tend to stay loyal to it.

Plug arrives from another dimension with a clear job: seek out people who are down on their luck and lift their spirits. She is a Juuden-chan, one of a group of otherworldly girls who use electricity to cheer up people on the brink of despair. A special device ranks each person's gloom from A, the worst, to F, the happiest. Like her co-workers, Plug can fly, slip through solid objects and draw magic plugs out of power transformers. Her latest assignment runs into trouble when she meets Sento Oumi, a boy who can see and touch her and often greets her with a baseball bat. The girl she needs to recharge is his sister, so Plug has to find a way past him first. Expect a comedy with ecchi and sci-fi touches, adapted from a seinen manga by Ditama Bow.
