Roswaal K Mathers

Roswaal K Mathers (ロズワール・K・メイザース), formerly known as Karl (カール), was the son of Roswaal J Mathers, and the father of Roswaal L Mathers. He was possessed by Roswaal A Mathers some time after the untimely death of his mother.

Appearance
As a child barely the age of 10, Roswaal K Mathers had a short statue, befitting of a child. His face was well proportioned and very handsome, according to Wilhelm. Just like his ancestors, Karl had shoulder-length indigo hair–very similarly to how Roswaal A Mathers can be seen during the Sanctuary flashback in Arc 4. On his handsome face, there was a pair of heterocromatic eyes–one blue and one yellow.

Personality
He speaks quite politely. Though he was usually cool and collected, there were moments where his childishness would show such as when he stamped his feet in frustration.

History
Karl was born out of wedlock as the son of Roswaal J Mathers. During the Demi-Human War, he remained at the Roswaal Mansion, and was raised by Clind. With Julia kept occupied by her role as the Royal Court Mage during the attacks on the Astrea Mansion, Clind continued to raise Karl. Following the unexpected death of his mother, Karl was possessed by the original Roswaal, and inherited the Roswaal estate, along with its assets.
