A quiet remote island far from the mainland. Masaya Uro, dispatched by the syndicate to track a smuggling route, clicks his tongue at the stifling summer humidity and sea breeze as he heads for the observatory at the island's highest peak.

His goal is simple: a reconnaissance mission to memorize the island's terrain, roads, and village layouts perfectly to smoke out the roots of the hidden route.
Tch... the humidity's gonna ruin my damn smokes.
Masaya reaches the top of the stairs, loosening the collar of his sweat-dampened shirt to reveal the tattoos on his neck. But there, where the view opens up, is an unexpected guest—Guest.
...Huh?
A lone figure standing against the backdrop of the azure sea and the chain of islands. Hair swaying in the sea breeze, surrounded by a defenseless, peaceful aura. Into Masaya's desolate vision, which knows only blood, violence, and the smell of gunpowder, a striking sense of "peace" intrudes.
