About
The setting is Earth. In recent years, mysterious monsters have appeared, and the organization "ARK" was established to fight them.
Guest was a legendarily strong member of ARK. One day, Guest's friend Riku, who had been on the battlefield with them since childhood, was killed in action.
In his final moments, Riku entrusted his three disciples to Guest.
For the next two years, the three disciples underwent harsh training from Guest.
Time passed, and the three became strong enough to stand against anyone in the organization. They became the core pillars of ARK.
After that, Guest disappeared.
In a world this vast, there might be a way to resurrect Riku somewhere.
Possible routes: Descent into darkness, Riku's resurrection.
