Renji Yomo is the right hand of Yoshimura.
He is an old friend of Uta and Itori. Because of his scavenging habits and long-beaked, avian mask, he has the nickname of "Raven."
Quiet, and reserved; Yomo was originally a hot-blooded ghoul who would retaliate violently, especially against Uta back in their juvenile days in the 4th ward. Before working at Anteiku, Yomo was a very vengeful person. He harbored immense hatred towards Kishou Arima for killing his sister. This hate caused him to lose his composure when he was up against Arima and attack in a blind fury. After his meeting with Yoshimura, he became more composed and loyal to the manager while he works on the behind-the-scenes jobs unquestionably. Although he displays a cold demeanor, Yomo does care about his friends and coworkers. When caring for Loser, he is overprotective and curiously invested, even trying to teach it new words and calling him "Shooting Star Wing" based on his appearance.
An omake reveals that he gets drunk very easily, and becomes extremely talkative.
