Rona Kestina

About
Rona Kestina is a young girl at service of Dark Lord RedEye. Her descendant was an incredible scientist Kestina from over 2000 years ago that created the parasitic gem known as RedEye, powerful enough to be a Magic Lv3 user. However, the gem was stolen by Demon King Nighcisa and turned into a crazy Dark Lord.

Kestina cursed the gem so that it would only remain alive as long as the Kestina blood-line remained. This was done in order to avoid the tool to turn against his master but upon turning into a Dark Lord, he required the Kestina family to be kept alive, so he enslaved the family and has bred them as his slaves for countless generations up to the present. Rona is the last member alive from the family, so if she were to die, so will RedEye. It is unknown how she came to be the last one of the family.

She's constantly tormented by him, who uses her as slave to clean her metallic body or work for her. She sometimes attacks her weak magic spells for fun, although limiting his power to minimum to avoid causing any sustancial damage.

Since she was born and raised under RedEye's domains, she was treated as a sub-human with absolutely nothing, and she was only taught very basic things to live and to speak. She's weak and malnourished, wears broken and tattered clothes and is heavily abused by him.

When Rona was old enough to conceive a child, RedEye caught a random man and forced him to rape her until she got pregnant to continue with the lineage of the Kestina family. He's currently eagerly waiting for the birth to expand the Kestina family further.
