Lenessia Erhart Cowen

Occupation: Princess of the Rose Garden Race: Human

Granddaughter of Sergiad. Known as the "Winter Rose of Eastal," she is a delicate beauty with silver hair, popular among both commoners and nobles. However, she is actually lazy and pessimistic. She is uncomfortable with Krusty, who can see through her true nature and thoughts at a glance, but she also trusts him. Due to the circumstances of recruiting volunteer soldiers in Akiba without the consent of the Lords' Council, she moved to Akiba as a liaison between Eastal and Akiba, establishing the "Water Maple Pavilion" as a branch office. She studies daily to handle consultations from both adventurers and "People of the Land." As an important figure connecting adventurers and "People of the Land," female members from various guilds gathered under the guise of a "tea party" to guard her, forming the core raid group "Maidens of the Water Maple" that resolved the "Murderer Incident" in December. She has become close with Akatsuki and Riese.

In the third season of the anime, she struggles with being pressured into an engagement with Touri, the head of the Saiguu family, but after hearing a message from Krusty through Misa, "If you wouldn't be upset about losing it, it was never yours to begin with," she appears in the Round Table Conference uniform while Shiroe is secretly meeting with Touri, and breaks off the engagement. During the subsequent Akiba general election, she is appointed by Shiroe as the chairperson of the new Round Table Conference.
