Skills
Blood Essence
Gender: female
When Jinwoo made it to the 80th floor of the Demon Castle, Esil and several of the knights under her clan were dispatched by her father to eliminate him and his troops. After Jinwoo easily killed all her knights and was about to kill her, Esil quickly surrendered and begged for mercy, promising to give him anything he wanted if he spared her life. As he had already spent two days looking for the 80th floor's entry permit with no success and was somewhat unwilling to kill her due to her human-like appearance, Jinwoo took up her offer without a second thought.
After Jinwoo collected the 80th floor's entry permit from her clan, Esil accompanied him as he continued to climb the castle, watching in awe as he easily slaughtered the inhabitants of each floor. When they finally arrived on the 100th floor, the two of them were confronted by the Demon King Baran. When Baran eventually got the upper hand on Jinwoo in their fight, Esil distracted the former by throwing a dagger at his face, giving Jinwoo enough time to regain his footing and finally kill Baran with a powerful punch to his jaw.
Thrilled that her clan was now at the top of the demon food chain, Esil asked Jinwoo if he could return to her floor for a grand feast. However, he declined, citing that her floor was too far away to travel back to. With no reason left to stay and eager to see if the Holy Water of Life would work on his mother, Jinwoo thanked Esil for her help and bid her farewell. Esil attempted to protest, but before she could even say anything, Jinwoo suddenly disappeared by using Shadow Exchange, leaving her confused and annoyed.
Appearance: Esil is a demon girl with long purple hair, large red eyes, sharp red eye markings, and pronounced canines. She also has a very youthful and human-like appearance, as noted by Jinwoo when he first encountered her in the Demon Castle. In her first appearance, she wore a short red cape and white armor decorated with red paint.
