Roswaal L Mathers

Roswaal L Mathers (ロズワール・L・メイザース) is the lord of the Roswaal Mansion and the descendant of the original Roswaal. It is later revealed that he is in fact the original Roswaal, who has been possessing his descendant's bodies.

Appearance
Roswaal has long indigo hair with heterochromic eyes, the right one being blue and the left one being yellow. He has a purplish skin tone. His eyelids are decorated by purple eye shadow, though the left eye's is longer. He wears clothes that can be described to those similar to a clown, consisting of a black hat, a top and bottom with different shades of purple, along with red and black boots and a cape.

According to Echidna, the original Roswaal had long, dark gray hair and yellow eyes.

Personality
Roswaal cares about Ram and Rem, becoming concerned when Rem died of an unknown cause. Because of his relations with Demi Humans, he has been rumored to have a thing for them, however Garfiel speculates this is actually because he's been gathering halfs to the Sanctuary.

In actuality, his body is possessed by his ancestor, whose purpose is to meet his teacher Echidna again at any cost, even if that meant sacrificing himself or those close to him, making Echidna describe him as being "a little too earnest". He has figured out that Subaru is looping through some method, causing him to challenge him, and subsequently lost. Though he has agreed to help him after losing, he has threatened to force him to loop if he makes a mistake.
