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. Since his meeting with Yoshimura, he gradually became more composed and loyal to the manager while he worked on the behind-the-scenes jobs unquestionably. Although he displays a cold demeanor, Yomo does care about his friends and coworkers.
