Esil Radiru

Esil Radiru is a supporting character in the Solo Leveling anime (particularly appearing in Season 2 during the Demon Castle/Return to Demon Castle arc). She is the eldest princess of the Radiru Clan, a noble demon family that rules over the 80th floor of the Demon Castle dungeon.

In terms of appearance, she has a youthful, surprisingly human-like look for a demon, featuring long purple hair, large red eyes, sharp red markings around her eyes, pronounced canines, and elf-like ears. She typically wears knightly armor (initially white with red accents and a short cape, later gray with blue and black plating) and wields a rapier in combat.

Personality-wise, Esil comes across as open, honest, and affable despite her demonic nature. She's also shown to have a somewhat selfish and shameless side (e.g., quickly begging for mercy and prioritizing her own survival), along with elements of clumsiness, vulnerability, and a mix of noble dignity. She provides some comedic relief in her interactions and develops loyalty toward Sung Jinwoo after he spares her life, eventually accompanying him through the castle floors and aiding him against the Demon King Baran.

Her voice actress in the anime is Riho Sugiyama (Japanese).
