Yeah, the WN series for this just ended around May-June of 2025, while there are two LN volumes out yet.
Not sure whether the Manga adaptation would be similar to WN (haven't read the LN, only seen it's illustrations), but MC is goona end up with a big Harem, like in millions, because not only he has hundreds of girls from this Isekai, he even gets entangled in Another World were the male population has died and that world is on brink collapse because the god managing that world ran away after giving up on it, so MC bangs the surviving thousands of women (including bio-androids) in that world to repopulate it and turns into a god to stop that world's collapse.
Fair warning though, if it turns out to be like the WN, then this series would have Incest theme, which includes,
- Stepmom (whom we see in this chapter) who actually likes MC a lot and helped in the coup to protect MC's life, though her planned fell apart as he was sent to the frontline even though she wanted him to be sent far back from war
- Younger Half-Brother, who gets permanently gender-bend to a Woman and loses his memories (after his memories got extracted and sent to an alternate past timeline which has him as the MC, though Author didn't write that plot yet only hinted)
- birth Mother, post revival from dead
- Daughters, and also his Sons who fall in love with MC immediately after seeing him for first time and decide to gender-bend permanently (MC ends up becoming a God and also creates spell to increase life of his Harem members, so all his children get born as gods, and gods can change sex anytime they wish)
