Bio-
Tsurugi no Kanshiki Joukai a french rapier forged in the 16th century as a sign of leadership within the Joukai Family. A sign of power, a sign of rank and a sign of leadership was it's main reason to be created, the blacksmith added a portion of shoku to it, forcing the wielder and the katana to become one in power thus he also, unwillingly, guaranteed that only the strongest in the Joukai Family would wield it and therefore only the strongest would be the Family's Head. Once Arashi Joukai decided to take up the challenge of gripping onto the hilt of Tsurugi no Kanshiki Joukai he already knew that he would easily handle the sword, yet him being a Hybrid changed the sword. Not only that it grew in power, it's blade also became drenched in a sinister black while the sharp side took on a dark violetish color.
