Six months ago, Karukozaka High School was sucked into the demon world, and in the ensuing chaos, only two survivors emerged: Nobu, who defeated the Demon Lord that took over the school, and Yumi, who possesses latent demon powers of her own.
Although they're both trying to put the incident behind them, the gateway to the Underworld remains open, and soon Nobu finds himself battling demons right on the streets of Tokyo. The reason for this infestation is simple: a secret organization is trying to establish a Demon Kingdom on Earth by summoning demons through the gateway.
Nobu and Yumi are the only people to have been to the Underworld and survived, so they may have the power to stop the infestation but before that can even happen, they'll have to find each other first.

From MangaHelpers:
This is a story of how an esper meets a girl in a small northern town. Tsubasa lives in a dying hot springs town, and he's a mostly friendless middle school delinquent. He actually has super powers, though he thinks of them more like embarrassing and useless powers. Sure, he can use his telekinetic abilities to brush his teeth while getting dressed, or read a book while drinking tea, but for the most part, it's easier just to do stuff with his hands.
One day, though, he hears the thoughts of a mute girl, Yuki, who is targeted for rape by other delinquents, due to her silence. He comes to her aid, and finds that to his surprise, he's able to manipulate her body to beat up her attackers! Unsurprisingly, she draws the conclusion that she is the one with super powers. Since Tsubasa's the only one who "knows her secret," their story together is just beginning!
