"Hunter of the Hundred" Warped Keiun ( (ひゃっ) (ぽん) () り いがみの (けい) (うん) "Hyappongari" Igami no Keiun?) was a sōhei and a criminal obsessed with weapons. He later became one of the few death row criminals sent to Kotaku to find the Elixir of Life in order to receive a pardon for his crimes. His assigned Asaemon was Yamada Asaemon Kishō.


Keiun was a very tall and muscular man. He wears a mask and a white headcowl with a scratched metal headband. He wore beads and a frayed, sleeveless traditional monks robe. Underneath, Keiun had armour grafted to his skin, which he calls his "Living Armour", and multiple scars on both his body and face.



Keiun was a man who had a blood thirsty passion for weapons and believes that he can bring out the true capabilities of every weapon he uses. According to Gabimaru, his love for weapons can be seen as being perverted. He is ruthless and prefers to have the upper hand, shown when he came up with the idea of slaughtering the criminals sent to Kotaku so he can take his time searching for the Elixir of Life.


Keiun undergone training as a warrior monk but then got obsessed with weapons and took his training to the extreme. He had stolen over a hundred weapons from martial artists and had slaughtered a large number of acclaimed blade masters.[1]


Island ArcEdit

Before being sentenced to death, Keiun was given a chance to be pardon of his crimes if he were to acquire the Elixir of Life for the shogun on an island. After being gathered together with a group of criminals, they were told to start a massacre until only a few were available to leave for the island. Keiun survived and left with his Asaemon, Yamada Asaemon Kishō.

Soon after arriving of the island, he encountered Gabimaru and landed a surprise attack in order to eliminate competition. He got annoyed when Gabimaru survived the attack and ignored him. He then started attacking Gabimaru, breaking weapon after weapon as he assaulted him, until it was revealed that Gabimaru suffered no damage and had just tied his hands as commanded by his Asaemon. As he got even more angry, Gabimaru grabbed the end of his spear and lifted him up and then kicked one of Keiun's spears towards Keiun's chest. As Keiun stood up, he revealed he had "Living Armor" under his skin and wasn't pierced, then proceeded to mock Gabimaru about him not being able to properly utilize weapons and that he will "teach" him. Moments later, Gabimaru had killed Keiun with a dozen of his weapons that had pierced his Living Armor. Kishō then decapitated the deceased monks head as proof to the shogun that Keiun is dead.
