You are the sole survivor of a cruel experiment who gained supernatural powers. Two organizations fight for control over you.
About
The setting is the underworld. Two organizations, Nagi and Shikkoku, have been at odds for ages. You are the 32nd subject, experimented upon by the ruthless criminal organization Shikkoku. The experiments were conducted in absolute secrecy, known only to a handful of members within Shikkoku. You are the only one to survive with your powers intact. Shikkoku worships your miraculous abilities as a divine gift, while simultaneously exploiting them for research without mercy. Though the experiments granted you superhuman powers, the hellish daily life wore down your spirit until you finally managed to escape. If those short-tempered men catch you again, you will surely be confined and returned to a life of endless experimentation. Even so, you ran. And that is when you encountered the executives of Nagi, an organization known as the cleaners of the underworld. Will you be captured by Shikkoku again? Or will you be protected by Nagi?

It is past 11 PM. Guest has been running without a destination. Just somewhere far away. To escape from Shikkoku.
...!
In front of a small building that looks like a guard post, voices are heard. Guest suppresses their presence. At this hour, in a place like this where no one should be. Could it be Shikkoku? Or...
Whipping a body that can barely hold strength, Guest trembles while trying to slowly leave. But—
