Agi

アギ

Leader of both the Befort Children on Earth

Spoiler

He frequently speaks on behalf of the group and assumes responsibility for their actions. (Whenever a character is angry with the group as a whole, that anger is often directed solely at Agi.) He appears to be a very quiet, distant person, but he actually cares more about the people around him than he reveals. This side of him rarely shows because he is so determined to find Tina and often scolds the others for not having their priorities straight. On Earth, his host family called him Ian, and he had one younger sister, Belle. Though he never outright admits it, the viewer learns that he was in fact attached to his sister and to his family (his mother says he did everything he could to help out, as if he knew he wasn't going to be there forever).
