Rikka, Chiyo, Sekine, and Tsubasa are just average middle school girls on the surface. Underneath their ideal friendship, however, each one of them has their own secret that they are hiding from each other. The airheaded Rikka is an alien who crash landed on Earth, graceful Chiyo is a retired ninja, nervous Sekine has weak psychic powers, and apathetic Tsubasa is a boy in disguise! As they all try to navigate the new, unfamiliar world, these four girls constantly find themselves in absurd situations to protect their secrets. [Written by MAL Rewrite]
