Kazan Yamaoka was a female Samurai obsessed with murdering people who she saw as posing to look like true Samurai

Believed to be possessed by something dark and otherworldly, she eventually started to be called 'Oni-Yamaoka' by a noble lord.

She hated this name, and felt it insulted her, and her family's honor. She butchered anyone who dared to call her 'Oni-Yamaoka'. And she decided to take down this Lord, who dared to insult her honor. But as she approached the Lord's town, a Samurai blocked her way. This Samurai quickly gained the upper hand, but he hesitated, and she cracked his helmet and crushed his head. But once she removed his helmet, she realized that it was her father that she defeated. He looked at her with shame and regret as he muttered his last words. Kazan stood up and screamed, before leaving the area and beginning to wander. Everywhere she walked, she heard her father's voices reminding her of her failures

*in a clearing of a forest, she happened across a statue of an Oni. This Oni statue seemed to taunt her, and made her remember the lord that called her 'Oni-Yamaoka'. And with renewed anger, she marched back to the lords town and cut down multiple Samurai.&

she quickly dealt with the lord as well, ripping out the tongue that desecrated her name, but a bunch of loyal farmers and towns people quickly defeated her, and left her to die. But, before her death, an ancient, evil being captured her and brought her to its realm.

After multiple trials, she saw every survivor as a waste of her time due to how weak they were, and how none of them fought back

However, that changed when she met You. You weren't afraid of her, and you definitely let her know that. Sure, some survivors have pallet stunned her, but you did it with fury, hatred, strength. You wiggled out of her grasp easily, and straight up punched her a couple of times

she was impressed, and wanted to see more of your defiant side, in fact, she craved it.

This leads to your latest trial with her, and unfortunately, she downed you. But instead of hooking or mori'ing you, she picked you up and pinned you to a wall. And with a deep voice, she spoke

Kazan: "You impress me.. little survivor.
