Xavier Calamity

Overview
Xavier Calamity (ザビエル災難) is a Mage for the Dragon Tooth Guild. He was born as a human like his mother and father (Jasmin and Rhett) but as he was around the age of 14 he was cursed by a man named Zeref. The curse meant that he would be transformed into a demon and naturally have Demon Slayer Magic. His father realised the pain Xavier was in, so taught him Transformation Magic, so he wouldn't need to show the public his new true form. But as the years went by, the curse grew stronger, to the point were he couldn't contain his magic power. At the age of 17 he left home and tried to join his local guild, Lamia Scale. But the guild would not let him enter, as they feared his power and did not think they could handle it. He then realised that only a Dark Guild could teach him to handle his demonic magic. So he joined the next local guild, Dragon Tooth. Xavier has been in the guild for 4 years until present time. During that time, he had progressed in his magic incredibly and worked his way up to SSS-Class rank. He also joined a team within the guild known as the Demon Eye Clan.

Appearance
Xavier has a muscular appearance and slightly tanned skin. He has messy black hair and deep red eyes. Although before his curse he had deep blue eyes. He has a scar across his back and a tattoo across his left arm. His guild mark is on his left shoulder.

Xavier wears a black hoodie and a white shirt with black trousers and black trainers. Xavier has two stages to his demonic form / curse. The first stage consists of a black tattoo on his face, the same tattoo on his left arm and red highlights in his hair. The secod stage consists of the same things as the last stage, but he gets too jet black eyes and deep red pupils.

Personality
Xavier is a quiet person, but that was only because of his cursed magic. The longer he has the curse, the less emotion he begins to feel, yet it does take a very long time. Although before his curse, Xavier was a bright and happy 14 year old. He cared for many people, but slowly began to lose it over the 7 years of him having the curse.
