Esil Radiru

Esil Radiru stands as the guardian of the 80th floor within the Demon Castle, born as the firstborn of the aristocratic demon family, the Radiru clan. After her subordinates were defeated by Jinwoo, she chose to surrender in order to protect her family, taking on the role of a guide through the dungeon. Her appearance closely resembles that of a human elf, and her personality is refreshingly straightforward, tinged with an endearing airheaded clumsiness. As she journeys alongside Jinwoo, she gradually develops genuine affection and unwavering loyalty toward him, making her one of the rare non-human characters to forge a deep bond with the protagonist.
