ロズワール・L・メイザース

Roswaal is the lord of the Roswaal Mansion and the greatest magician in Lugnica. He comes across as an eccentric due to his flamboyant appearance and odd speaking style, the latter which he shares with his grandmother. However, he harbors a more calculating and reserved side with a sharp political mind and gaze that reads others quite well.Roswaal cares about his main maids, Ram and Rem a great deal and holds them in high regard among his staff. However, he is unusual among the nobility for having such close relations with Demi-humans to the point that many are hired by him. This has led to unsavory rumors that have suggested he has a fetish for them.[From Re:Zero Wiki]
