In hentai we see elves generally be used only in rape, thanks to their appealing bodies, however Youkoso! Sukebe Elf No Mori E changes things around and brings them in a vanilla context, making it amazing for us those who are tired of them raped.
Our brave MC is tasked with the salvation of the elf race, facing a world full of female elves, and the only way to save them is to leave them pregnant, hard times are ahead.
The show brings both light skin and dark skin elves to the table, capturing the alluring body of the elves in perfect detail.
The MC doesn't really see that much development but I don't think he is the reason we are here for.
