In his younger days, Akisame traveled the world to further the development of his unique Jijitsu style, taking in aspects and inspiration from other styles he studied. He later met and became friends of Miu's father, Saiga. During one of his journeys, he met the child and not-yet-named Shigure who was raised deep in the mountains along with her father who was a great master at both crafting and wielding weapons. Because her father was suffering from a terminal illness, he requested Akisame to take his life away in a duel so that he could die a warrior's death. Akisame initially refused, but eventually had to throw him off a cliff after a forced confrontation. Before dying, Shigure's father admitted he did not really want to die in battle, but was trying to be a bad example so his daughter would avoid repeating his mistakes. Akisame then gave Shigure her name and took her to be raised by Akisame's old friend, the late master of the Kōsaka-style. Akisame and Kensei Ma accepted a student for Ryōzanpaku against the Elder, who stated that he saw a sinister look in the young man eyes, protest. After sometimes the student was expelled from Ryōzanpaku. After Hachibore Kosaka passed away, Akisame brought Shigure into Ryōzanpaku.
He had mentioned that he has been a child being bullied like kenichi.
