Magma Blossom

Magma Blossom (マグマ花, Maguma Hana) is a Volcanic Magic Spell utilized by Shiranui Ryūzetsu.

Description
With this spell, Shiranui is able to expel Lava from her mouth before shaping it into the form of boulders of molten rock. Due to their composition, the boulders can melt through most objects with ease, and because a considerable number are dispersed over a wide range in quick succession, they are also difficult to avoid.
