Mibu Soujirou

A master of the sword from the countryside. Every single who crosses swords with him dies in a completely random way. At the earliest, within several weeks; at the longest, within several years. At first, it was something to laugh at, but time passed and an attitude completely changed. He became a feared figure. As a result, he was made a vassal by Nakanoin Reizen, who believed that this principle could be applied not only to humans but also to higher beings such as Tenma.

He participated in the Fencing Kagura ceremony and

killed honorable warriors from the Chigusa, Iwakura and Rokujou clans with a sudden attack, but in the end, was defeated by a Sakagami Habaki.

Soujirou was following the path of a demon of the sword. He deemed his fellows the ones to be cut. His sole intention and desire was to cut, cut, and cut, before he would be the only one left. This would be a testament that he is the strongest swordsman. He did not care about honour or comradery and did not want to waste any time on his path.

While time passes, Soujirou changes his ways and comes to understand certain truths. There is no point in killing in haste; one ought to be cut in due time, at due stage, otherwise fame will not spread. There is no point in killing trash; only those who are strong and worthy of challenge have a value to be cut. There are no premises not to spend time with others, even if they are to be cut. There should be an opponent, with whom one can fight; otherwise, if one to be left as the strongest swordsman, he would not be able to move forward and truly maintain his position.

Thanks to his duel with Shiori, the path to Hajun was cut open.
