Asugi is the son of Saizo, the nephew of Kaze, and the cousin of Midori. Like the other children of Fates, Asugi was placed in the Deeprealms to protect him from the war. As the son of Saizo, Asugi was given training in hopes of having him succeed as the sixth in a line of Saizos, given that he is the first born son. However, the pressure of becoming the next Saizo proved too much for him and he decided to discard that name, instead naming himself Asugi. According to him, that name means "gray". Sometime later, Asugi was hired by bandit gang lead by Funke who wanted to raid a nearby mansion. Although paid by candy, Asugi had doubts of the mission and wanted out.
