So basically a bda like Destructive Death but altered to be more like the Muay Thai fighting style and have attacks that resemble Destructive Death since that’s what it’s based on, and have 7-8 abilities. The breathing style that I think would be cool is one called the shadow breathing moving as fast as the darkness that consumes the light and in the shadows of trees or whatever makes shadows in the area you are in, it would have 9 forms or 8-10 bda abilities if you make it a bda since it might suit demons better.

There is a shadow bda in Rengokus spin off but I'm guessing the shadow breathing is your custom
