This is Vohaku as a human. While in this form, he goes by the alias Kamada Shin in order to keep suspicion of who he really is to a minimum while around those not part of the syndicate. His memories have mostly been suppressed since his transformation into a Lekkon, but he faintly remembers working for the Yakuza at some point as one of their main hitmen. His body sports several bullet wounds as well scarring from weapons such as swords.
He speaks more freely and shows more emotion in this form and is willing to voice his displeasure when certain orders are given, but he still will not disobey them.
Kamada Shin, Vohaku (c) mine.
Pokemon (c) whoever owns it.
