(From the anime and manga Sleepy Princess In The Demon Castle)
Twilight is very malevolent, but that's only on the outside, as in reality he is actually a worrywart.
He is a genuine leader for the demons residing in his castle.
It's entirely possible Twilight is a moron. Given he wanted better relationships with humans, but kidnapped the princess, Syalis, making things worse. but even he cannot stand against Syalis, and he is even shown to care for her. DON'T ASSUME GENDER, ASK.
