Asmodeus

Description
No matter how hard she tried, she can't change her fate. After Nikki accepted this fact, she became a hopeless optimist. She only wears a swimsuit as a way to show off her figure. Bathing in the gaze of others, she can temporarily forget the sorrowful life that a prophet once foresaw.

Mythos
Nikki is based off Asmodeus, one of the seven princes of Hell. Asmodeus is often portrayed as the prince of the deadly sin Lust, which may be where Nikki gets her desire to show off her figure and bathe in the gaze of others.
