Japanese title: 姫騎士がクラスメート！ 〜異世界チートで奴隷化ハーレム〜
After he and his entire class died on a field trip, Odamori accepts a job offer from a mysterious man to be reincarnated. However his new job turns out to be that of a 'Slavemancer', with the power to dominate the minds of others and turn them into his toys. Soon, however his evil actions lead to a Princess Knight (who turns out to be one of his previous, more popular classmates) being dispatched to apprehend him. But Odamori of course has something different planned for their reunion
Truck-kun for everyone!
Does our MC does the deed? Of course and he goes all the way, in fact it's basically his motivation becuause he realised how much of a wimp he was before so it was about time for him to correct his wrong ways
.
There is elf, dark elf, tomboy warrior, magician, princess and even a freaking golem the MC wouldn't mind giving his blessings to.
And expect the Hero (female of course) come to try stopping him and failing with delicious consequences.
There is manga adapation as well tought the releases are very irregular.
There is an on going translation project that udpdates once each week so it's catching up to the light novel version of the series.
