Hampnie Hambart

Hampnie Hambert (人喰い玩具 (ハンプニー・ハンバート)) is a man who suddenly appeared in Ai's village in search for someone. He calls himself the "Man-eating Toy", and describes himself as a cruel person. He also claims to be immortal and unable to age.

Hampnie's goal in traveling is to find a woman named Hana. He became immortal 15 years prior the current story-line when God abandoned the world. In the case of death, his body will return to its prime state.

Personality
Despite the fact he openly describes himself as cruel and mean more than once, and apparently has a cold personality, he's instead kind on the inside.

He affirms to deeply dislike the dead, that's why he never hesitates to kill them. That also explains as to why he killed Julie's wife ten years ago.

Appearance
Hampnie has white hair and red eyes. He wears a dark coat and is often seen smoking cigarettes. He is immortal with the looks of his 17 years old self, even if he is already 32 years old.

Story
Hampnie first appears at Ai's village one day. Upon arrival, he proceeds to "kill" everyone in the town, or at least immobilize them. He then lets Ai bury the bodies.

Soon after he introduces Ai to Scar and explains to Ai that she can't be a true Grave Keeper. He tells Ai that a Grave Keeper is supposed to be emotionless, but Ai clearly has emotions. This reasoning is made clear by the emotionless demeanor Scar carries. Furthermore, Hampnie informs Ai that Grave Keepers do not have parents, as Ai has a deceased mother. Hampnie then proceeds to ask Scar to bury the villagers' bodies in order to "truly" put them to rest, but Scar says that she can't sense any dead in the vicinity of the town. Much to Hampnie's surprise, this reveals Ai might actually be a Grave Keeper afterall. This is because the dead can only be truly put to rest by a Grave Keeper.

In episode 3, it is revealed that he is actually Ai's father, and his real name is Kizuna Astin. Just a moment before he dies as human, he left his name, Astin, to Ai as his daughter, making her name become Ai Astin. When he wakes up as undead, he spent one full day with Ai, from morning to evening, before he was buried next to Hana, by Ai herself.
