Guy Cecil has long been the childhood friend of Luke Fon Fabre, as well as a servant to the noble family of House Fabre. Guy is normally an easy-going fellow, doing his job of protecting his friend and sparring with Luke in sword training. But it isn't long before it's discovered that Guy holds a secret reason for his employment to House Fabre. He actually plans to take revenge on Luke, for being the son of Duke Fabre. Guy is actually of nobility; his real name is revealed to be "Gailardia Galan Gardios". Duke Fabre invaded the Gardios house one night years ago and killed his family. All the women of the house, including his sister, rushed to save the young Guy, but they were slaughtered before his eyes. He awoke to find himself buried in their corpses, triggering his gynophobia. He then infiltrates House Fabre as a servant and vows to himself to hurt the Duke like the Duke had hurt him. However, Guy's friendship with Luke changed his mind and he rejected his ideas for revenge, although he admits to still having some suppressed rage regarding the issue.

Maybe this rage will fuel him through his future encounters in the DL. With powerful sword techniques as well as some limited healing, Guy isn't a force to be taken lightly.
