Dias Lepunzo Elemanso Oplane Fatsbalm VI (ディアス・レプンツォ・エレマンソ・オプレーン・ファッツバルム六世) is a chef. She has an assistant named Rodriguez.


Dias is a petite Elf with golden hair. She normally wears a hooded cloak to hide her identity in order to successfully trick people, though she also hides her identity so she won't get any anti Elf prejudice directed toward her.


Dias is a lively girl as she find joy in tricking people through her false rumors. She is also perceptive as she was able to see through Subaru's disguise and Roswaal's true intentions.
