Description
Renner Theiere Chardelon Ryle Vaiself serves as the Third Princess of the Re-Estize Kingdom, youngest daughter of King Ramposa III and half-sister to Crown Prince Barbro and Second Prince Zanac. From birth, her intelligence, observational skills, comprehension, creativity, leadership, and rulership capabilities manifested exceptionally overdeveloped. This profound intellect isolated her as no one understood her, gradually warping her mental development. Her life shifted upon befriending an orphan boy named Climb, who clung to her every word and became her sole emotional anchor.

Publicly revered as the "Golden Princess" for her benevolence and landmark reforms—notably abolishing slavery—Renner meticulously crafted an image of purity and kindness. She adorned fashionable white dresses and a golden necklace of nobility, her long golden hair and sapphire-like eyes cementing her saintly facade. Yet this persona veiled a psychopathic, detached core. She perceived everyone except Climb as expendable tools or abstract concepts, feeling neither love nor hatred. Her gratitude toward subjects mirrored a mundane appreciation for sustenance.

Her true nature surfaced as a yandere fixation on Climb, whom she called her "puppy." She vowed ruthless death to anyone harming him, her love twisting into a desire to chain him permanently into dependency. To preserve Climb’s admiration, she performed charity—feeding the poor, founding orphanages—while covertly manipulating politics. Despite reforms, corrupt nobles and her low royal status constrained her influence.

During Jaldabaoth’s demon invasion, Renner unveiled her strategic genius. She coordinated adventurers and royal forces, dispatching Climb on a perilous rescue mission within a demon-held fire wall. Privately, she confessed to Marquis Raeven and Prince Zanac that if Climb died, she would resurrect him weakened to "care for" him eternally—sacrificing royal guards as demon bait to achieve this.

Her betrayal crystallized through covert pacts with Nazarick. She allied with Demiurge to dismantle the Eight Fingers syndicate, ensuring Climb’s safety through cooperation. Later, she negotiated with Albedo to orchestrate the kingdom’s annexation by the Sorcerer Kingdom. As reward, Ainz Ooal Gown transformed her race into a demon. Post-change, she shed her human guise, gaining fangs, black claws, small wings, and a black dress with a black rose crown. She retained her "Golden Princess" act solely around Climb.

After the kingdom’s fall, Renner established orphanages to scout useful individuals under public-order pretexts. Her loyalty to Nazarick became absolute, reinforced by Albedo’s threat to execute Climb upon betrayal. Her capabilities positioned her for consideration as an Area Guardian-level entity within Nazarick’s hierarchy.
