The Raging Black Bull

Recombination Magic: The Raging Black Bull (組替魔法『黒の暴れ牛号』) is a Recombination Magic spell.

Description
With an open grimoire, the user rearranges a magic house into the shape of a giant bull that they can control.

In Combat Style (戦闘スタイル), the house shifts into a bull that stands on two legs. There are three cannons - two in the shoulders, one in the chest - from which the user can launch blasts of mana. These blasts can also be used to launch and amplify other spells and to launch people.

In Charging Style (猛進スタイル), the house shifts into a bull that runs on all four legs.
