Demon Yamada
CharacterDemon Yamada was a notorious S-rated ghoul, also called the Investigator Killer, who lived to hunt down strong opponents. After a CCG team finally brought him down, his kakuhou was harvested and forged into the quinque that bears his name.
Appearance
Yamada carried a powerfully muscled physique. To match the nickname he was given, he covered his face with a mask shaped into the leering visage of a demon.
Personality
Above all Yamada craved a proving ground for his own strength, chasing after difficult prey and killing investigators simply to feel tested. That hunger eventually drew a coordinated response, and a team that counted Fujishige Iba, Kureo Mado, and Yukinori Shinohara among its members ran him down, with Shinohara landing the killing strike.
Abilities
As a bikaku-type ghoul, Yamada enjoyed the heightened toughness and rapid recovery of his kind, along with the raw agility and power that came from his physiology even apart from his kagune. His bikaku itself extended into the shape of a long butcher's blade, a fitting tool for a predator who sought out battle. The trail of First Class and Associate Special Class investigators he cut down earned him an S-rating, and after his death his kakuhou was repurposed into the quinque known as Demon Yamada 1.
