Kasuka Mado

Her face is never fully revealed, though the resemblance to her daughter Akira is strongly implied, the main difference being that Kasuka wore her hair flat. Like the rest of the CCG, she appeared in the organization's formal dress.

Little of her nature is shown, but she came across as courageous and firm of will, squaring up to the One-Eyed Owl by herself. She also clearly held deep affection for both Kureo and Akira.

Kureo had married into her family, who happened to be his professor, after she first refused his proposal because she would not give up her surname. Both served the CCG, and ten years before the series they joined a 24th Ward operation under Itsuki Marude. Deep inside, on the 124th floor, the squad ran into the One-Eyed Owl. With casualties mounting and victory unlikely, Marude ordered Kasuka, the strongest of the team, to stall the creature alone while the others pulled back. She was slain and devoured, her scattered remains later recovered by her husband. Akira remembered her as an investigator of real strength and skill who reached high rank while still young, and her death struck Kureo and Akira hard, fueling Kureo's hatred of every ghoul.
