Haha ga Dark Elf ni Natte Isekai kara Modottekita. ~Eroero Dekichau Oyako Kankei~

One night, Takumi Kusamori—a young man with little going for him—is chilling at home when a sudden flash of light blinds him. When the light fades, he finds a dark elf standing before him. ………………Wait, a dark elf?! “Don’t you recognize me? It’s me, your mom!” “Huh? Whaaaaat?!” His mother, who died in a car accident years ago, had been reincarnated as a dark elf in another world… and now she’s back. At first, Takumi is completely thrown off. But eventually, he comes to accept this bizarre reality. The days they share become a chance to relive the childhood he lost—a time full of warmth, care, and boundless love. And before long, things start to get… intimate. “We’ve been apart for so long… You can ask on me for anything you want, okay?..” [Translated from the official website]
