Futari wa SxS

Reo and Michiru are best friends who were born on the same day, at the same time, and in the same hospital. Reo is a kind-hearted all-around athlete, while Michiru is a beautiful nerdy girl. These two polar opposites get along very well. But... that's not the only thing that makes them special. In fact, when they put their hands together, they can use psychic powers! This is a secret that no one knows, an SxS (super secret) that only the two of them know. But their classmate Takarada finds out about this secret! And what is Takarada's true identity...?!
