Haohmaru/Story

Past
At the age of fifteen, he challenged Jubei Yagyu to a duel but lost due to lack of experience. Jubei, amused by the youth's bravado, brought Haohmaru to Nicotine Caffeine so that he may gain proper training. Whilst living there, he also met and befriended Genjuro Kibagami, fellow student and another orphan like himself.

Both students were close friends, yet Genjuro's hunger for power worried Nicotine. To test his students, he tempted them to fight over the long-unused treasured sword, Fugudoku. They were tested by facing off with a group of other fighters. In contrast to his friend, Haohmaru fought only until his opponent lost the will to fight and didn't give chase. After Genjuro left Nicotine's home, Haohmaru was rewarded with access to the five-story pagoda that housed the aforementioned prized blade, where he was the able to cut it down to then claim the blade as his own. Encouraged by his master to further improve himself, Haohmaru travels the lands perfecting his sword skills, and searches for worthy challengers in the name of Shura.

Haohmaru continues to travel the land to polish his fighting skills. However he notices a mysterious woman has been persistently tailing him. Haohmaru has no idea who she is, but he is soon reluctantly caught in the designs of the evil, dark figure who manipulates her. It's later revealed that the mysterious puppeteer called Yuga the Destroyer, is seeking a male counterpart to Shiki and chooses Haohmaru to fulfill its requirements for a perfect resurrection. The two face each other and Haohmaru emerges victorious destroying Yuga's physical form in the process. A year later, a brainwashed Shiki and Shadow Asura ambush Haohmaru and turn him into a cold blooded murderer also known as “Sword Demon Haohmaru”. Together with Shadow Asura and Shiki, they defended the entrance of Yuga’s lair.

After the two Asura's killed Yuga, Shiki along with Haohmaru were finally freed from Yuga’s influence and returned to their normal states. In Genjuro's ending, he and Haohmaru face each other once more, but this time Genjuro gains the upper hand. Before he could deal the final blow, a boy stabs him in vengeance for his unnamed father. It's heavily implied that Genjuro dies from his wound and, as promised, an older Haohmaru toasts to his friend's honor. Shiki leaves her daughter under Haohmaru and Nicotine's care as her servitude to Yuga made her feel unworthy of being a mother.
