Henrique Bonnavizzie. Codename: Lusion. An italian mercenary who was hired by the Church to hunt down those who go against It. Soon after he joined, they've found out that a spy had infiltrated in their secret order, and Henrique was sent in a mission to hunt down and kill the traitor. After some weeks of research, the clues led him to belive that the traitor's next objective was in the secret academy for sensitive young, R.F.A.. But during his research, he found about a new, interesting person, one known as "Zero". Now, in a mission that might cost his life, he must investigate and eliminate both Zero and this traitor they call "X", a letter that was the only hint he left behind.

He is fanatical for justice, never gives up on his goals and fights for the common good, though he still has a lot to learn about what is TRULLY good....
