Kite

A dark lord in Kayblis faction. Formerly a human called Kakutomi Kite.

Personality
He's quite sympathetic, respectful and cortious, even against his enemies from Hornet's faction. Kite is a compationate Dark Lord that helps weak humans in need, and often visits a village near the monster realm where humans are kept in quarantine, protecting them from monsters and providing food and money. Despite this he joined Kayblis, whose main goal is to kill Miki Kurusu and kill all the humans. He hates human society as a whole, because he despises nobles and kings that live in luxury while hundreds die of starvation or diseases. In Kichikuou Rance he was enraged after seeing the castles where nobles lived in Zeth, and slaughtered them cold-bloodedly.

Story
When he was still human, his sister fell ill to an uncurable disease and sent to an isolated village near the demon realm. This village was often attacked by monsters and in a very bad state. He trained martial arts to become stronger and be able to help her.

A few years later he was finally able to visit his sister, but he was told that she wasn't there any more and never knew wether she died of the disease or from a monster attack. This shocked him and kept training and fighting aimlessly. Eventually he became famous and became a Dark Lord by Demon King Gi.

Five hundred years later he still visits the village giving money to the patients there to improve their living condition and killing the monsters coming near it.

This disease seem to transfer by skin touching, and only girls in their teens are suspectible to this disease.
