Title itself is misleading, read synopsis.

Apart from it being what it is, which is an erotica I'd like to point out that the main character / protag is kinda very quick to change his values and the story pacing might be confusing at times.

I have yet to read a class transfer which is actually the 'cliche' one and where the protag doesn't decide to take revenge on everyone and instead saves the world, however a nice comparison might be "the forsaken hero" *which is currently on halt as the author... more>> is rewriting the volume*

Personally, the premise of the forsaken hero is much better and thought out than this one but maybe thats just me. *At leas the premise that is* <<less

So long story short this novel doesn't have hardcore NTR as the title would lead you to believe

tho I must warn you the shifts in PoV tend to be slightly confusing and the other characters are rather skewed to be on the bad side, or are totally disposable, or manipulable, which really paints a picture on how the MC acts, the MC himself is rather bland with practically no core values that eggs him on ~ ... more>>

Spoiler

basically makes his decisions based on his dick

there is no world building so to speak aside from the normal cliche of otherworlds like magic, demons, corrupts? Nobles, knights, etc. The pacing is rushed at time to make way for the erotica which face it, is practically 70-90 % the reason we read this sort of thing it does pave way for hard wood but overall the novel is bland not a total failure I assure you its worth the read just don't pretend that its actual plot heavy.. Tho it does have varying forms of "plot"

a solid 3.5/5= so lets say 4 / 5 for arguments sake <<less

You want a good Isekai Novel?

One with decent world-building? Passable pacing? Good plot? Then, find something else. This ain't it.

This one is just the novel you wanna read for the smut, nothing else.

One bad example that makes it bad is:

The MCs plan of action on expanding his harem which up to this point is only made up of 5 members. Sure, if the pacing is alright then that's fine. But the MC keeps spending precious time f*cking her other already captured heroines, when he knows that he has a time limit. He keeps saying he has to but keeps approaching his 5 girls alternatively.

Also one more thing. The series has been dropped by the translator I think. So not worth your time. <<less

Very good harem isekai. MC’s cheat power is dominating women through sex, but the author actually takes the time to investigate topics like the social structure of the class and what happens to it once the girls start falling to the MC. Also the MC starts off just satisfying his lust and desire for revenge but eventually starts to have real feelings for the girls as a consequence of sleeping with them over and over again. Based on the cheat power and setting you’d expect a typical isekai power fantasy... more>> trash but in reality the author explorers more advanced topics which is something IMO unheard of in this genre.

But, of course since it isn’t pure trash no one feels like translating this for long. You’ll need to go to Soyetsu to continue reading. Author updates about once every 1-1.5 months. <<less
