Rengoku's Father Traumatized Lower Moon Two! s a human, Hairo learned Bushido and developed proficient swordsmanship, but during one encounter with firearm-wielding soldiers, his faith in his skills faltered when he saw the superiority of guns in comparison to his swords. The soldiers shot at him, but Hairo survived the shooting and was transformed into a demon soon after. As a demon, Hairo once had an encounter with the Flame Hashira, at the time Shinjuro Rengoku. Despite the demon being much weaker than him, Shinjuro mercilessly slashed his hands repeatedly without killing him and ignored his pleas for mercy, due to him forgoing his duties as Hashira and being drunk at the time. Though he was spared, Shinjuro taunted him for fleeing from him despite being a demon. This single traumatic event would prove to be Hairo's primary drive to become stronger, and eventually, Hairo developed a powerful Blood Demon Art to use both his fighting styles. In addition to making him stronger, the encounter had a profound effect on the demon's mentality, always filling him with fear and rage at remembering the face of Shinjuro.
