Alessandro Serpi

Former member of the Coven and member of an ancient family of magi. This Italian magus, born in Rome, was abandoned by his father, Marco Serpi, and also by his mother. He spent his teenage years in the Coven and fought the Holy Grail War of Yggdrasil alongside the Saber-class Servant: Gaius Julius Caesar.

In that war he met a Master named Friedrich Wolff and teamed up with him to stop the dangerous Yukiko Kumahira and save the world from the Devourer-class Servant: Sheol.

At the end of the war, Alessandro decided to travel around the world and met Ina Shandilya. It was he who introduced her to the world of magic.

He's a very powerful magus. When he was in the Coven he was considered one of the most talented magi. The Magcraft he uses is called harmonic magic, it's based on the combination of magic words and particular sounds (in his case: snap of fingers).
