4-nin wa Sorezore Uso wo Tsuku

Rikka, Chiyo, Sekine, and Tsubasa look like four ordinary girls and close friends at an all-girls school, but each is hiding a truth that could destroy their everyday life if exposed. Rikka is an alien military officer, Chiyo is a former ninja, Sekine is a weak telepath, and Tsubasa is actually a boy forced to take his twin sister's place at school.

The problem is that their secrets constantly interfere with one another. Sekine's telepathy does not work properly on alien Rikka, Chiyo interprets ordinary events through her ninja experience, and Tsubasa is trying not to be exposed in a place where he is not supposed to be at all. Every simple school situation becomes another test of the lies that somehow keep their friendship together.
