He loathes others so much that he loves them. They do say, keep your friends close and your enemies closer!
He acts sickeningly sweet, like a cup of hot chocolate with far too much sugar put in, it's difficult for some to bear. It isn't so much of an act as he is trying so desperately not to loathe your very existence. He believes that if he treats others with an extreme amount of kindness and adoration that he might actually start to like them. Yet, the young man is extremely pessimistic and childish, taking any sort of insult as a challenge and personal attack. Being sweet one moment and haughty the next means he's quite a moody person, and hates others invading his personal space.
He likes getting up close and personal, his comically large gloves are his weapon of choice. No matter how fluffy and soft they appear to be, with enough force Maestro can crush someone's skull with a single blow, though he's not nearly powerful enough to do that kind of damage. He still is able to pummel others to a bloody pulp if given any reason to.
Maestro was never an easy person to get along with. He was always negative about everything and it was a chore for him to attend Demon School on a regular basis without wishing that everyone in the class would die in a horribly coincidental accident while on their way home from school at the exact. Same. Time. As he grew he began to live by the quote "Keep your friends close, and your enemies closer." even going so far as to, no matter how disgusted he was of the idea, hug other classmates in an attempt at making peace. It never quite worked out, though, because his moodiness always crushed his attempts at being nice.
