After being pushed to her physical and mental limits, she is rescued by her allies, Ryuusuke and Mikoto. Traumatized but determined, Brain Jacker vows to reclaim her dignity and destroy the monsters who humiliated her.
Gerald reveals his true identity as a Pegasus and a traitor to the Lin family, capturing Lin Kaifon to seize her Ruin Arms. Using a potent aphrodisiac and the help of vengeful orc research subjects, he subjects her to a series of brutal humiliations designed to shatter her pride. Ultimately, the once-proud heiress is broken, forced to renounce her status and submit as Gerald's slave.
