Renner Theiere Chardelon Ryle Vaiself

"Yes, it would indeed be difficult to do while putting up a front as Princess. Plus, there is no use if it's done by force. His gaze, I want to chain him up completely and raise him like a dog."

- Renner to Marquis Raeven about Climb, revealing her sadism

Personality
Initially presented as a caring and sweet young princess, Renner soon reveals herself to be nothing but an obsessive sadist. She is renowned for her wisdom beyond her age, and it's later shown to be beneficial for her manipulative skills.

Secretly, Renner is also selfish and never cares about anyone else at all. The only person she seemed to care about is Climb, her personal guard, but she only sees him as her possession with a sense of twisted love. After being secretly joining Nazarick, she does not hesitate to betray her kingdom, family and people without a shred of remorse.

Described as a spiritual heteromorph, Renner is a human, yet one of the most inhumane characters in the entire Overlord series ever, even worse than the likes of Clementine. She understands the concept of both good and evil, but she is not hestitated to commit evil traits to benefit her own goods. Overall, the Golden Princess is the type who was unbound by the petty constraints of morality. Instead, she wold calmly worked for anyone, even the fearsome Ainz Ooal Gown, to advance her own agenda.
