I'm interested but the lack of it being ongoing or completed at more than 4 volumes doesn't really give me the desire to buy it. JNC has enough stalled/dead series as is.
One of the OG, yeah. No Reincarnation / Otome game, but it seems to be the progenitor of the modern Villainess sub-genre. Released in Web Novel form in 2012, two years earlier than Bakarina from what I could tell.
I live in hope that since they will redoing the website in the near-ish future, they will be able to build in the infrastructure needed to offer these kind of steamier R-18 romances.
Recently I've managed to get my hands on the two drama cds for this series. They cover the first two volumes of the novel and although I wasn't able to understand it all, it was nice to listen to the voices.
Just finished reading all the scanlated manga chapters. I really want to read the novels now. Hope JNC or some other publisher gives FRank Onii-sama an official English release.
It's definitely has an OP protagonist with his personal harem. The women make the first move however since he still sees himself as a 40 year old salary worker rather than a 18 year old with OP skills. Granted he had to earn those skills, but they quickly stack within a few months once he experiments with the system.
