Biagio Busoni

Biagio Busoni is the antagonist of Volume 11. His rank is that of a Bishop, which has the power to command 1000 soldiers for his project. He was assigned to be the overseer of the project to remodel the "Queen of Adriatic Sea," orignally a weapon that could only target Venice, into a weapon that can be used anywhere, namely Academy City. He is a ruthless man who sees the glory of the Roman Catholic Church as everything, willing to sacrifice the lives of everyone on the guardian armada in order to preserve its name.

His magic unleashes any hidden meaning in his crucifix cross, both Christianity and pagan.

As of Volume 14, he's captured after the events of Volume 11 and is locked up in the London Clock Tower along with Lidvia Lorenzetti.
