Ai

Age: 12-13

Race: Human

Occupation: Grave Keeper

A 12-year-old gravekeeper. She is quite naive, but cares a lot about others. She calls Hampnie Hambart her "father" due to something her supposed mother had told her when she was younger, and decides to follow him on his journey. She can get very emotional at times which could lead to her being put in dangerous situations.

[Spoiler] Her real name is Ai Astin (アイ・アスティン). She is half-human and half-gravekeeper, and was born after God abandoned the world. After finding out that Hampnie is actually her father, he dies and Ai buries him. [/Spoiler]
