Start of the last three!

Here's Wakiya!

As a Demon Slayer, his Breathing Style would be Thunder Breathing - the fastest of the Breathing Styles - and he would know all six forms.

As a demon, his Blood Demon Art would be Eternity Blitz. He can run at the speed of light; not a single being on Earth can outrun him, not even other demons. His speed makes it seem like he can teleport, or that he can pause time. He can devour an entire human in less than two seconds - and he can devour an entire town's population in less than five seconds.

What do you think?

And to those who have been waiting, Quon is up next!
