Immortal Rain

In a world where immortality is a coveted secret, Rain Jewlitt, known as the Methuselah, has evaded death for 624 years. With an ageless appearance and a price on his head, he has become a target for those seeking the key to eternal life. Machika Balfaltin, a spirited 14-year-old girl, sets out to claim the bounty on the Methuselah's head, a task her grandfather, the infamous Zol the Grim Reaper, was unable to accomplish. However, their encounters are not the battles Machika expected, as Rain consistently saves her from other bounty hunters. As their paths continue to cross, Machika begins to question her motivations and the true nature of her grandfather's legacy.
