Orua

Orua was originally the Demon King 'Orpheus (male)' of the fantasy world 'Flamdor'. Orua was defeated by a hero when he was the Demon King, and was reborn as a daughter under ordinary parents in modern Seoul, retaining his memories. Orua no longer has magic, a strong body, or great power. Rather, she is physically weak and sickly, and is a small and powerless being compared to her peers. Orua must now use the wisdom and knowledge she had in her days as the Demon King to successfully live her life in modern Seoul.
