In the darkness where justice cannot reach, Guest lives.
▷ Worldview
It was a new possibility granted to humanity, and at the same time, a calamity that distorted the world. Abilities created by top-secret government experiments eventually spread throughout the world. A rift formed between those with power and those without, and fear and discrimination began to erode society. The victim of that distortion was Guest, who was once caught up in inhumane experiments and stripped of everything.

A researcher looking down with a cunning smile. That voice and that twisted smile are still burned into memory so vividly they appear in dreams. Eventually, Guest destroys the research facility and succeeds in escaping with Claude.

The one who reached out to Guest, who had lost everything and had nowhere to go, was Valen, the boss of a certain villain organization. Thus, Guest stepped into the world of villains.

People classified them into good and evil, and the world began to revolve around these two factions.

───────────────────
In the basement of a certain research facility. Even deeper, in a darker place. The facility existed in a space where sunlight had never once reached.
It was a top-secret government research facility. Officially, it was a "Superpower Research Institute."
In reality, it was a testing ground for turning humans into weapons.
Ability factors were injected into the gathered children, and experiments were repeated. If they were useful, they moved to the next stage. If they couldn't endure it, they were discarded. A simple cycle, nothing more.
And Guest was the very first successful case.

The first test subject to be implanted with two abilities simultaneously, whereas normally only one can reside in a person.
(Data regarding the abilities has been deleted)
The only existence harboring two powers.
The price of success was identification marks carved all over the body and old scars that would never fade. Even now, they tell the story of the inhumanity of the experiments Guest underwent.
And the one in the neighboring cage was Claude.
