Who would win?

Dabura

Or 

the entire kill la kill Universe.

Dabura claps,like all he needs to do is atomize everything or turn the life fibers to stone with his spit and it's a quick win XD.

Like bruh ragyo and nui aren't gonna do anything to someone who can blow up their planet.

it would take just spitting on ragyo and she's done and Nui is fucked two her abilities wont work when knowing she'll be vaporized.
