Satoshi Hara was a Samurai and member of the Akeyuki. Renowned for his ferocity in combat, Satoshi was a renowned warrior in his sect, having been granted great praises by the former Shogun. When Tokihakiri was brought in from the blizzard when she was young, Satoshi agreed to train her, watching over her as her longtime mentor. Tokihakiri looked up to him like an older brother, gaining inspiration in the things he did. When Tokihakiri became Shogun, he continued to train her until she learned everything he could teach her. His loyalty to Akeyuki never faltered, even in the midst of war. He remained loyal up until his untimely death, jumping in front of an arrow fired by Zenjou, taking the shot that was meant to be for Tokihakiri. This would end up awakening Tokihakiri's Mangekyō Sharingan
