Hello I would like to create a mythical zoan based around the yokai Bakekujira

The ability would be the reverse of the phoenix fruit, the user would be able to create fire that causes sickness instead of burning.

The character I want to give it to is currently unnamed but my plans for her are for her to be known as lady death due to her Skelton appearance that is a result of partial transformation and some drugs she had taken. I would like to put her in paradise but I'm fine with moving her to new world
