Itsuki Marude

Marude is dedicated and serious about the work he does as an investigator. As a senior investigator, he is strict on his colleagues, but is not above caring for their well-being as seen when he constantly scolds a young Kishou Arima for executing ghoul exterminations independently without permission from the CCG. He is shown to be rather abrasive with his subordinates, with Shinohara and Houji commenting that he is not one to show consideration to his investigator's feelings. He also grabs and holds Katsuya Mabuchi by the collar when he thinks he is being messed with. This seemingly extends to his private life as he is intentionally single and has no interest in marriage. However, after his investigation of the Washuu clan, he becomes disillusioned with the CCG and notes everything was a lie. This prompts him to dispatch Yoshitoki, confirming his defection from the CCG. He morosely ponders that discovering the conspiracy ensures the investigators who died cannot rest in peace.

Marude is a slim, middle-aged man with short black hair, which was much shorter during his younger days. Similarly to the other ghoul investigators, he wears the formal suit and tie.

Despite Marude being shown as a tactical leader and never in direct combat, he possesses incredible skills as a ghoul investigator. Being of the Special Class is testimony in itself, earning the luxury to sit in office and command posts when war breaks out. Marude seems to have a high proficiency with firearms, as he was seen to easily shoot down two ghoul snipers with two short rifle bursts from a distance, whom his subordinates struggled against in the crossfire. * Rc-piercing round: Marude used this weapon in his battle against Kichimura Washuu as it was strong enough to destroy Kichimura's kagune.
