Everyone, keep those requests coming!

Here's Lui!

As a Demon Slayer, his Breathing Style would be Mist Breathing, though he mostly uses the styles that deliver the most damage.

As a demon, his Blood Demon Art would be Smoke Screen. He can create a thick smoke from the various pores on his body to either disorient or kill his opponent. His smoke types range from Sight Impairing to Suffocating.

What do you think?

And who's next? GIMME!
