Strange murders are happening in Tokyo. Due to liquid evidence at the scene, the police conclude the attacks are the results of 'eater' type ghouls. College buddies Kaneki and Hide come up with the idea that ghouls are imitating humans so that's why they haven't ever seen one. Little did they know that their theory may very well become reality.
Seidou Takizawa (滝澤 政道, Takizawa Seidō) is a former Rank 2 Ghoul Investigator. A classmate of Akira Mado at the Academy, he was partnered with Kousuke Houji and assigned to the 20th Ward to investigate the Gourmet. Though a great admirer of outstanding investigators such as Koutarou Amon and Kishou Arima, he also suffers from a major inferiority complex that brought him into conflict with his peers.
At the end of the Owl Suppression Operation, he faced Tatara together with Koutarou Amon and was subsequently reported dead by the CCG.
In Tokyo Ghoul:re, he survived as an artificial one-eyed ghoul. As a member of Aogiri Tree, he is known as Owl (オウル, Ōru).
