Carlos is energetic and definitely one of the loudest people you could ever meet. He always has a lot to say, causing both having an easy interaction with anyone or annoy beings around him. Carlos also loves to joke around and have fun, but his big sense of humour sometimes lets him go a lot, causing his jokes making a disaster. Despite his flaws, he has a big heart, for example being very sensitive to the harm of anyone. 

From an early age Carlos was trained and mostly raised by his father, leading him to strive to be the strongest wizard and set the goal of protecting the town. He doesn't care if some people make fun of him, all that matters for him is improving his skills and has high hopes for his future. Even tho he finds satisfaction in learning new magic spells, he hates school and prefers spending time in his own way - usually practicing fighting by himself or chilling on a tree.

Considered as an odd kid, Carlos didn't have many friends to get along with - until the day he met Edward. From the time of their friendship, they began to trust each other and even consider each other as brothers. Despite their opposite personalities, they have very good contact to this day, spending every day together.
