Zol Balfaltin

Zol the Grim Reaper: Machika's grandfather, and also the famous bounty hunter who was later assassinated. The only bounty that he could never catch was the immortal Methuselah. His trademark weapon was his scythe, which Machika now carries, and he was the closest person to Machika before she met Rain. There is a miniseries prequel about the encounter between Rain and Zol AKA Shinigami of the East in the Japanese Magazine "Huckleberry".
