When Bishamon arrived at an old antique shop, as if drawn by fate, he found a strange piece of armor and a sword. At this moment, he lost his own thought. When coming back to his senses, he was at his house. The armor and sword was sitting beside him. When he went back to the store to ask what happened, he found out that he y forced the owner to give the armor and sword to him. At the time, his wife Orin worried about Bishamon as he sat in front of the armor for days. She asked him to let go of the armor and sword but, Bishamon heard nothing of it. Two weeks later, he decided to ignore his wife and wear the armor. Bishamon's mind was full of hate and accursed power. He had donned Hannya, the armor of hate and Kien, the blood sucking sword. He went on countless days of killing as Hannya demanded more sacrifices.
When coming back to his senses, it was to late... His body was lost, recreated by the use of the killed victims's souls.His mind, even if sane, failed to comply with the body and so, the armor took his body and mind.
Hannya, The Cursed Armor: It is thought that it came into the human world roughly 600 years ago. The armor would grant its master inhuman abilities, but in return would turn them into a blood thirsty killer. The armor would shine brighter the more blood it was bathed in, while the person wearing it would slowly lose their life.
Kien, The Blood Thirsty Sword: A long time ago, a sword was forged by the name of "Onikiri". As a sword is used to cut a human, its edges would dull because of the fat and blood within a human body. But the Onikiri became sharper as it cut more people due to the way its edges were made. People feared the sword due to the illusion that it would suck into a human body. It was said that if the user did not kill one man a day, the sword would drive its user insane and kill them. As it had its own mind, it managed to change his name into "Kien".
"This armor has taken my life. It is time I see its powers."― Bishamon upon donning the armor
