He has a rather child-like personality, showing child-like expressions. He has wide range of imagination, seen in Episode 2 of the anime where he tries to guess the reasons behind the multiple escapes done by Nico, Rock and Uno. He is also shown to have a desire to become stronger and surpass Enki Gokuu, his older brother. His appearance resembles a monkey. While he is doing his paperwork he is seen eating a frozen treat. He is also shown to have a very short fuse, especially when people taunt him about the incident regarding his older brother or just the mention of Hajime's name.

He also gets frustrated at Inori's reluctance to do his work and often punches him for avoiding his work. Samon can get offended by the warden as she confessed that she pats Samon on the head because Samon is shorter than her.

Samon also hesitates to attack Enki despite the fact that Enki is an escaped inmate. Samon was also shocked to hear from Inori that many guards under him were unhappy with his leadership.


When he was younger, he would always train with his older brother whom he admired greatly.

Before working at Nanba Prison, Samon worked with his brother at a prison in China. While working in the prison in China, Samon met Upa for the first time, where he passed him a present he had received from Upa's family. This shocked Upa, whom had initially presumed that his family believed him to be dead. However, Samon told him that he was the one who told his family the truth and that it's not wrong to tell someone that he was alive, and that he just wanted to clarify things before leaving, telling him not to cause any more trouble.

When Enki was still the head supervising officer of Building 5, Samon was the deputy supervising officer. After Enki betrayed Nanba Prison and killed an inmate, Samon became the head supervising officer. Till the present time, Samon was unable to understand why his older brother betrayed him and the other guards.
