Lydia felt her mind changing as well as her body: somehow she was becoming cuter and sexier. Her eyes became violet and catlike and a pink tail with a pink bow with a golden bell attached tied onto it sprouted just above her behind as her elven ears turned into pink triangular ones on top of her head. Her hair turned an adorable bubblegum pink. Whiskers sprouted on her face as her feet and hands became digigraded, with retractable claws underneath. Her breasts also grew and firmed up and she developed a bubble butt and wide hips. Her clothes became cuter and pink.
As for her mind, she began to think more like a cat. She also developed hypnotic eyes and began to feel differently about the succubi sisters. She was devoted to them, obedient to them, and loved them more than anything else, but also demanded they pamper her and treat her like the princess she was. And with her cuteness and hypnosis, they could never and would never bring themselves to deny her that pampering. After all she was, is, and always will be their favorite pet. In exchange, she would obey their every command, lure unsuspecting victims to them with her hypnotic violet eyes, and become super duper extra cute at the snap of their fingers, something they had conditioned her to do. They also could turn her into a full kitten and back to neko-chan at will. She could also speak and understand Japanese now as well as English. Her memories of being an elf or a fighter were completely gone. All that remained was a sweet, shy but sometimes bubbly, devoted, innocent, and pampered neko-chan.
"Kainushi no yoko ni aru, Seina-chan!" one of the sisters called out.
Lydia, now Seina-chan, perked up.
"Hai, watashi nyo shoyū-sha!"
She practically rushed to their side. One of them began to pet her head.
"Anata wa itsumo watashitachi ni chūjitsude kenshin-tekidesu yo ne?" the succubus asked in a hypnotic tone.
Seina-chan's eyes glazed over.
"Hai," Seina-chan agreed dreamily with no hesitation.
"Watashi wa itsumo anyata ni chūjitsude kenshin-tekidesu."
The succubus smiled.
"Anata wa itsumo watashitachi no kyūto de amai chīsana neko no on'nanoko ni narimasu yo ne?"
"Hai," Seina-chan agreed, once again instantaneously.
"Watashi wa itsumo anyata nyo kyūto de amai chīsanya nyeko nyo on'nyanyoko ni nyarimasu."
The other, unable to resist the cute cat girl under the hypnotic trance, used her magic to paralyze Y'sha and rushed over, also petting the new cat girl.
"Hai, anata wa watashitachi no jūjun'na koneko no on'nanokodesu. Kawaikute amai jūjun'na koneko hime," they said in sync.
"Hai, watashi wa anyata nyo jūjun'nya konyeko nyo on'nyanyokodesu. Anyata nyo kyūto de amai jūjun'nya konyeko nyo ōjo."
One of the succubi sisters pulled out a cute pink collar with a golden bell, just like the one on her tail while the other pulled out a cute pink crown. They tied the collar onto her neck and placed the crown on her head and her eyes flashed, signaling that the transformation was complete. There was no going back.
