not worth your time just go read something else...
this manga tries to be a dark one but failed miserably
by using an mc that won't kill no matter what
he just let's go the bad guys like those others trash Isekai harem manga
instead of being a dark "manga"
it's just one of those cringe fest one...
damn this is the first hentai where i actually want a story (for both heaven and hell route) like what happened next like did humanity really got wipe out? is there still some survivors?
