Hachiroutarou Oomikami

八郎太郎大神

More than a thousand years ago, he ruled the region surrounding Towada until a group of Buddhist monks, led by one Nansobo, sealed him within Lake Towada.
Many generations ago, he encountered Tatsuko Kirigakure, an Iga ninja who was fleeing. Despite her injuries, she fought Hachiro and was defeated. She begged him for power, and moved by her passion, he healed her with his blood and formed a contract with her: he would give her a sword forged from his fang to protect her and her descendants, and she would give him a child and then die at the age of 30.
