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.

Appearance
Roswaal has long indigo hair with heterochromic eyes, the right one being blue and the left one being yellow. 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 her teacher Echidna again at any cost, even if that meant sacrificing herself or those close to her, making Echidna describe her as being "a little too earnest". She has figured out that Subaru is looping through some method, causing her to challenge him, and subsequently lost. Though she has agreed to help him after losing, she has threatened to force him to loop if he makes a mistake.
