Gender and age unknown.

A Witch, and one of the Devil Girls of Elting Memorial. Also the leader of Kashipa's middle-grade rooting unit, Lust.

When the Devil Girls were exiled by Hilder for doing what she had prohibited them, she disappeared with most of their research materials.

Infuriated Hilder ordered her capture, but she was never found.

Time passed and Hilder moved on to other serious things that happened in Pandemonium. Sisley resurfaced.

By this time, she had abandoned her own body for the very thing, the very essence of her research, that was forbidden to her.

Everyone who knew her in the past was shocked. She broke the rule beyond any taboo. The mages who once were her colleagues whispered among themselves.

But in the end, she was soundly defeated in the Bronx where she didn't want to go in the first place, lost her new body, which ended up completely destroyed, and disappeared again.

Having barely escaped, Sisley was angry. She'd lost the precious results of her research that took her a long time.

She spent countless hours hiding in a corner to create what she thought were the ultimate results. But her happiness didn't last long.

In the Bronx where she didn't want to go, she met him and he burned her work!

I can't stop now. I must not stop now. I broke the rules for the ultimate truth. For that, I even sacrificed everything—even myself!

If I stop now, my life will have been wasted. This time, I must create something flawless.

I'll break even the greatest taboo to discover greater truths.

I'll need so many things to do that. First... Yes, I need that thing that got away. Children, let's go. It's time to retrieve the "material."
