Chiaki

First appearance in manga: Chapter 228 She is a vampire under Hikawa's leadership. She appears as a young woman wearing a suit, with long dark hair, and is nicknamed after Gogo Yubari of the movie Kill Bill due to their extreme resemblance. Her first appearance is that of a normal girl going with some friends to a club which is in fact the vampire's base. Although Akira Kurono tries to protect her, Hikawa defeats him and takes her. She then appears as vampire attacking Kei Kurono. During that battle the mission transfer started, so, following Hikawa's example, she took Reika hostage and got transfered to the Gantz room with her. She is a skilled fighter who uses a katana in battle. She is quiet and rarely shows emotion, prompting her partner to become surprised when she laughs at the nickname Gantz gives him. After being released by Gantz, she asks Hikawa if they should kill the Gantz players. After he declines the idea, she follows him out of the room.
