23 (Slave)

23 was a slave sent in a destruction squad and rescued by Blanc. He appears disheveled and had the misconceptions of many humans about yoki. He was a little slow and used to being a servant for all of his life. He prefers not to kill but wants to see justice be fulfilled.

Blanc rescued him as he was sent to destroy a town and calmed down his raging yoki which engulfed his soul like a wildfire. At this moment, 23 saw Blanc as a god. Blanc had Iris teach him the basics before teaching him THUMA. He usually came along with Blanc and Iris, following Blanc and carrying their possessions and weapons, even though Blanc had never forced him to do so. He developed the ability to sense yoki by closing his eyes and later by hearing others, hearing Iris' moans when she talked with him that indicated her love for Blanc. He later tried to confront her about this but was ignored and chastised by Iris who was in denial. He stayed behind when Blanc and Iris went to revive Sullivan.

It is likely that 23 is Harold.
