Owl (フクロウ, Fukurō) was an ukaku-type quinque with a long handle and a large, jagged blade.
It was created using the kakuhou torn out during the battle between Kishou Arima and Yoshimura, making it the first known example of a quinque made from a ghoul who was still alive. It had the power to fire projectiles and the ability of using traps.
Since its creation thirteen years ago, it had never been used in battle. Its first use was when Arima faced Ken Kaneki in Cochlea during the Third Cochlea Raid. During their confrontation, Kaneki completely destroyed the quinque.
