NKKD-033 - My innocent girlfriend got ruined by a thug, and now she's a total slut

*I have purchased several works in this series, but this one is unique in that after being brainwashed, her appearance and personality have been changed to a gal.

A classic series trope where a quiet, innocent girl gets taken advantage of by her senior. Personally, I loved the transition where the innocent, uniform-wearing girl turns into a 'loli-bitch' to suit her senior's tastes. Mio-chan's performance, along with the outfit and makeup, worked well, and the gap from her initial innocence really heightened the NTR vibe. What's lacking is the interaction with the boyfriend. Watching it happen right in front of him (POV) is fine, but they should have had more interaction with her instead of just having him watch. It would have been better if they added more NTR elements, like making him hold her hand or doing it from behind in the first half to emphasize the misery, or having him kick or look down on her in the second half. Since it's a series, maybe they can't deviate much from the formula, but that's the kind of direction I'd like to see.

It's the familiar trope where he can't save his girlfriend from the aggressive thug, Senpai Waniguchi, and slowly watches her get stolen. The slight difference here is that the loli-style high school girl gradually transforms into a 'gyaru' as she gets dyed in Waniguchi's colors. Other than that, there were no standout scenes. I wish the plot had more exciting developments.
