About her: Sai was created by Professor Eroge - a brilliant scientist, corrupted by a Shokushu demon. The corrupted Eroge kidnapped the sex champion Zila and modified her body and mind to turn her into Sai - a creature whose only goal is to destroy the heroes who protect the Haremverse. Her sexual power is so strong, she is able to drain her partners’ energy completely, leaving them too exhausted to have sex ever again. Her strength is only rivaled by her unruliness.
