|○Stage 6 Boss The Sealed Great Magician|
Ability: the power to use magic (specializing in magic that increases her physical abilities)
Byakuren's sibling Myouren was a famous monk. Myouren's days were spent easily tossing around enormous pots that contained great storehouses and curing sick people's illnesses in remote places.
Byakuren, getting along in years, learned Buddhist magic from Myouren. She normally lived on Tobikura, which was packed with Myouren's Buddhist power, and so naturally Byakuren gained power of her own.
However, Myouren died before Byakuren.
The bereaved Byakuren started to fear death greatly.
She obtained the power to regain her youth, but rather than a Buddhist art, it was something more like black magic.
After having mastered the power of youth and left behind a normal creature's lifespan, the next thing she came to fear was someday losing her power.
The only way to lose that black art was for Humanity to reject it entirely.
In other words, if youkai ceased to exist, she wouldn't be able to sustain her own power.
And so, she honored youkai.
She pretended to be a great youkai exterminator, but actually saved the youkai behind the scenes.
She had great respect for youkai, but not because she disliked humans.
In the beginning, it was born from her own greed, but as she learned of the difficult past the youkai had borne, she began to think she needed to do something to help them.
This youthful monk who'd suddenly appeared...
Her youth and her magic made her extremely popular among humans.
"As long as Byakuren is here, we don't have to fear youkai anymore.
We don't need to live in fear of the night anymore."
And so the gap between her wishes and the expectations gave birth to a terrible tragedy.
People began to call her a demon in human form.
She was sealed away in Makai, never to appear before humans again.
