The Isekai Hitman

Kaito, a detached 17-year-old, awakens in Sekai, a world teetering on the brink of magical civil war in 1999. He's reborn with a chilling cheat: the complete memories and honed skills of his past life as America's most hunted assassin. Haunted by the echoes of his bloody past and the relentless pursuit of the FBI, Kaito now navigates a realm of mana and ancient sorcery, far deadlier than any cartel. His cold demeanor shields a deeper wound: the gnawing guilt of a life spent taking others, yet never truly living his own. As factions vie for control and shadows stir, Kaito must reconcile his killer instincts with the moral ambiguities of a new world, or risk becoming just another weapon in a war that isn't his, dragging his new existence into the same spiral of death he barely escaped. Will he find a purpose beyond the blade, or succumb to the relentless whispers of his assassin's past?
