Character from Solo Leveling by Chugong
A demon noble from the Demon Castle who allied with Jinwoo to survive, guiding him through the dungeon's floors in exchange for protection.
Esil Radiru is a demon noble from one of the Demon Castle's aristocratic families. When Jinwoo entered the Demon Castle instance dungeon, she chose to help him navigate the floors rather than fight him — a pragmatic decision that saved her life. She's small, red-skinned, and surprisingly earnest for a demon. She served as Jinwoo's guide through the Castle's political structure, explaining which demons controlled which floors and helping him find the most efficient path upward.
