Kyo

Kyo Shichinintai is the father of Bankotsu. He had met a young demon slayer whom was on a demon slayer mission only he attacked her and the young woman was in a lot of pain after Kyo gave her severe wounds. Her name was Akina Shizuru. Kyo felt sorry for what he had done as if he had feelings for her and Kyo's comrades smirked knowing Kyo was in love one of his best friends watched the couple carefully even though Akina's family didn't accept Kyo with her. These two managed to sneak off around as much as they can before they were caught and Akina's family realized that this love was an unbreakable one. These two couples fell in love deeply and got married then had one child named Bankotsu after Kyo's halberd Banryuu the first man who wield the sword that no one else can. Kyo was a legend known all over Japan but he was hated by most bounty hunters and warlords. That was it they had to bring him down and he was captured one night and was left without food or water and was stuck with the rest of the mercenaries.Kyo was only 21 when he died and they've tortured him to death tying him to a pole they kept throwing kunai knifes at him and his last words were. "If only I've got to see my son...Gomennasai Akina-chan..I love you.." was all he said and his beloved wife was forced to watch.So Bankotsu was born to wonder what his father was like. Despite Kyo's mercenary ways he would never kill children at all or mothers. The kids actually looked up to Kyo but the mothers wouldn't let them near this man because he killed their fathers but the children do not know that.Kyo has killed only 100 people so far and Bankotsu was destined to complete the banryuu of his fathers. Kyo's last requests to his friends was to descend the banryuu to his son when he is right of age to wield it so they did. Then Kyo died slowly.
