Undertaker

A deadly virus outbreak is turning the people of Japan into flesh-eating zombies. The government intervenes, trying to separate the survivors from the infected. Ryouichi, a young boy who has his family and friends destroyed by the undead infestation, becomes an assistant to an Undertaker - a person hired by families to kill loved ones who've been turned. Armed with a modified shovel and a bag, Ryouichi roams the ruins of Japan killing zombies and collecting body parts to prove to grieving families that their infected loved ones are now at peace.
