The story of four friends who each have a secret they cannot share with each other.

What do an alien, former ninja, weak telepath, and boy pretending to be a girl have in common? They are all classmates at Kashihara Girls' Academy, and they hide their true identities from the world. Rikka, Chiyo, Sekine, and Tsubasa seem like the best of friends, but they each harbor a monumental secret that they cannot reveal, no matter what. In order to continue masquerading as normal middle school girls, each of them must invent creative ways to conceal their true selves. But that is easier said than done, as the four students end up entangled in numerous shenanigans along the way.—MAL Rewrite

If this wild bunch isn't enough, their classroom is in danger of being destroyed...oh and Earth too.—Crunchyroll
