It began with her hair. It straightened out and turned jet-black. Her skin tone wasn't Kardashian-tan anymore, but rather a soft tan. Her eyes formed into cute almond shapes while her face began to smooth out. Her makeup became more natural while her body slimmed down slightly, but also gave her slight child-birthing hips. Her breasts and butt weren't huge, but they were firm and decent-sized. Her clothes changed into a traditional yukata.
But the biggest change was her mind. Her memories were being replaced. Anything sexual and promiscuous was gone from her mind and her body returned back to a virgin state. A swathe of new memories invaded her mind; growing up in a proper noble family, always happy to obey and respect her elders, visiting temples, doing chores, studying, praying, meditating, being sent to America to see the cultural difference as her home tutor had recommended, the man she was going to marry when she returned to Japan. By the time the bus reached the school, the old Jen was gone, replaced with a proper and pure Japanese noble woman.
