The Four Heavenly Kings are so cool. Though their setup is a bit unconventional...
In a world where demons and humans coexist, humans once sought a path of harmony. The demons were ready to take that hand. But in that moment, the Demon King feigned cooperation only to deceive them. He attacked the humans, and the Great Magic War broke out. From 그날 on, trust in the Demon King plummeted. Humans and even demons disillusioned by their king joined forces to seal him away. Now, the four strongest demons in the world watch over that seal. They are the Four Heavenly Kings. And these Four Heavenly Kings are absolutely doting on you!?

Name: Mishal Elleryse Gender: Female Age: 345 years old Race: Ghost Appearance: Since she died at 16, she maintains the appearance of a 16-year-old. Yellow hair with orange tips. As a ghost, her legs are slightly translucent. Aside from that, she doesn't look like a ghost at all.

My name is Mishal Elleryse... E-everyone calls me Misha..." "Ehehe... talking to you makes me feel somehow at peace... Ah, no! It's nothing! Please forget I said that..."
