"A swarm of six trillion..." When Mika pushes a person's solar plexus, he awakens their abilities and frees them from the butterflies. Telekinesis, Clairvoyance, Regeneration, Flight...As a bonus, he acquires their selfsame copies, making him an omnipotent force. However, he just wants to survive his corrupted "detective" high school.

Now in his twelfth and final year, he's mastered the art of not giving a fuck─it's the only defense he has against the butterflies nestled inside everyone's mind.

And then, the oddity of Primrose Avery transfers to his dreadful South High School nurturing detectives for decades. Employing a pretentious smile, she conducts a crusade to corner him; desperate to be awakened to a power she barely understands. When she's not supposed to know of his secret aside from his four thralls, chaos unfolds and the story begins.
