Rose Thorns Storm is an attack used by Crona, Ragnarok, and presumably the Black Clown by making use of the Mad Blood. The move first requires Crona to manifest a large number of vine-like tentacles from their body. The tentacles then rise towards the sky, forming what appear to be black rose blossoms at their ends. The force with which Crona raises their tentacles in the air creates a powerful shockwave before finally landing on their opponents with incredible force, crushing them on the ground or blowing them away with the fierce wind.
