Ai Astin

Ai Astin (アイ・アスティン) is a 12-year-old Grave Keeper. She is quite naive, but cares a lot about others. She calls Hampnie Hambert her "father" due to something her supposed mother had told her when she was younger, and decides to follow him on his journey.

Appearance
Ai has a very fragile and petite look to her body and face, with a flat chest and long goldish brown hair, and big bright green eyes, she looks more like a younger version of Alfa, with messier hair as the bangs that fall beside her cheeks have a few strands being longer then the others, unlike her mothers who's hair is well kept and neat with Cleopatra style cropped bangs beside her cheeks.

Personality
Ai is a very out going girl. She tries her hardest to fill her mother's shoes as a Grave Keeper and tries her hardest to please everyone in the village. However, as seen in Episode 1, she can get very emotional at times which could lead to her being put in dangerous situations.

Background
After her mother's death, Ai followed her duty to become the Grave Keeper of the village.

 * She is the last child born in the world about 12 years ago.
 * Ai is a half Grave Keeper and half human due to her mother, Alfa, being a Grave Keeper with emotions.
