I think I'm spending so much time in SE but anyway, here we go. I'm looking for a fantasy manga with some elements of sci-fi. I barely remember the actual plot of the story but I do recall the mc (a guy) fell in love with Kaguya. But Kaguya actually came down using a sort of UFO-esque ship (and is dead, I think). It has a harem genre with other girls trying to get the guy's attention(?). Apparently, these girls and some (if not most) of the women in this place transfer their consciousness to a baby as a form of "rebirth". I distinctly remember a woman wearing a kimono transferring her consciousness to a baby and she actually spoke as a baby and remarked that it's hard speaking because the baby has yet to fully develop. About the mc, I think he's obsessed with Kaguya and tries to create or fix the ship she came in. I'm not sure about how it went through. Also, he met this girl that has a scar from a heart surgery who is also part of the women in that village (or shrine).
Additional notes:
- The story is set in the present or at least "modern" where cellphones and tvs currently exist already because from what I can remember, the MC is wearing modern clothes.
- The MC also have flashbacks from a past life when he was living with Kaguya at that time (that past era is probably where the original Kaguya story is set in)
- Women in this manga also wears modern clothes while some wears kimono.
