Mai Hirano

The record preserves little of Mai's looks, noting mainly the barrette she owned, a hair clip that would later surface as a key piece of evidence in the case surrounding her death.

What emerges of Mai is her devotion to family and her persistence. She refused to give up on her missing sister, traveling to a distant ward and handing out flyers in the hope of finding her.

Mai made her way to the 11th ward after Mari went missing there while visiting a friend, passing out flyers as she searched. She met Kazuichi Banjou, who urged her to keep trying, neither of them aware that Mari was by then already dead.

Mai herself vanished a full three months ahead of Koutarou Amon's posting to the 8th ward. Two months after that, her barrette turned up near the ward's police station with a ghoul's bodily fluids on it, which flagged the matter as a ghoul incident and passed it from the police to the CCG. A shortage of investigators left the case dormant until Amon arrived and began working with Kyouhei Morimine, and together they eventually determined that Koharu Utsumi had kidnapped and killed her.
