Ashiarai Yashiki

It is seized by Tetsuo Tsutsumi.

She was an accomplished onmyoji. Alas, she did not pursue her talents for the good of the world or the people, but for her own selfish pursuit of beauty.
After a fierce battle, the woman dragged herself through the streets. It was like something had gnawed away at her body.
"Will I die? I've already obtained what I needed. As long as I have this..."
Suddenly, a terrible realization dawned on her. Her legs wouldn't move. She fell to the ground. What was happening? Surprised, she looked down. Her foot, once so beautiful and delicate, had grown ulcerated and rotten. He got her. She was on the verge of death and covered in filth to boot. Crawling to a nearby house, her breath caught in her throat. The curious residents opened up, but recoiled from what they saw.
"My foot is so filthy... Someone, please, quickly..."
The woman expired while mumbling something unintelligible. And so ended the life of a woman consumed by evil.

Ashino pursued the Rite of Resurrection to attain eternal beauty, pushing Seiman to research it. She manipulating the local daimyo and instigated the Honjo Incident in order to attain enough soul dregs for the Rite. She was killed in battle against Seiman, but her legacy continued through her descendant Yoko Fukunaga, who sought to resurrect her in late Showa-era Sumida.
