This is the best villainess manga out there, hands down. Chapter 9 sold me, 100%. Truly quality work from a creator moving out of his comfort zone. I was a big fan of Zoids when I was a kid (still am, actually), and I'm loving the references of early otaku culture from the 20th century.
Eh. There are only 9 chapters right now. Not really enough to form a decent opinion.
Still, it seems kinda weak and tacky for an otome-game isekai (or pseudo-isekai). I guess it can't be blamed on the fact that the subgenre is kinda high-quality in general. Tough competition and all that.
It can have a 6/10 for now though. It isn't too bad.
