Set to premiere sometime in 2024. Synopsis from AniList:
Naoe-kun, a massage therapist, is about to head home for the day when he’s saddled with a rather strange patient. This lovely lady has emerald eyes, pointy ears, and grew up in the forest–everything about her screams “elf,” except for one thing: her bodacious body. It turns out she left her world but loves junk food in this one, and now her obsession has caught up with her. Can Naoe-kun help this lovable elf girl lose the weight–and keep it off?
Ahaa! But that’s why I play both sides, by also starting up [email protected], I always win!
I also recall reading this manga. It has a funny premise, and for a while it balances jokes and nutritional advice well, but before long it devolved into fanservice. The character art is good, but the manga did not hold my interest either.
