Gekkō

Gekkō is a short, stocky man with short white hair combed into a mohawk and sideburns connected to his beard. He has dark yellow eyes, a large nose and a sparse moustache. Gekkō wears a dark jacket with a light t-shirt underneath, as well as pants and simple sandals. Gekkō's clothes as a member of the Byakuya Gang consists of a beaked poncho at the bottom end, in addition to a black wig with long hair and white mask, also long black pants with the same sandals and gloves that completely cover his hands. On his right palm, he has a cursed seal.

Once a shinobi from the Land of Snow, Gekkō worked closely with Ryōgi's father on missions. Ultimately, however, he wanted more and formed the Byakuya Gang, gathering allies under the pretence of helping the less-fortunate while steadily building up his own personal fortune. Realising Ryōgi's potential power, Gekkō killed the young boy's parents and altered his memories, making him think that Gekkō saved him from his parents' murderer. He then swayed Ryōgi into joining the Byakuya Gang, claiming that his father was also a part of it.
