This is a Supernatural story about some friends in Tokyo, who grew up together as childhood friends. They meet other beings who are either like them, or just original human beings. They were told from their parents to never expose what they are as their supernatural identity. When the childhood friends got to highschool, they understood why they have to keep their secret hidden as they learn more about what and who they are and where they come from. If a supernatural is exposed or captured, then they are taken by the SEO (Supernatural Execution Organization), and is experimented on by expert or mad scientists. If they survive the agonizing experiment, they live with a horrible, yet unforgettable memory. If not, then they are destroyed, or forever forgotten. The city, filled with surprises of unknown, is filled with confusion, revenge, and conquer.
