Ultraman: A Feast at the Monster Graveyard

(Multiple female leads + anything can be made into food + there's no problem a round of drinks and a steak can't solve.) The male lead accidentally transmigrates to the Monster Graveyard in the Ultraman world. Using missions from the System, he opens a restaurant there. But his ingredients aren't pork, chicken, or duck: they're monster meat. Here, aliens and Ultraman are all friends. They don't start fighting the moment they meet, and there's no scheming. They're all drinking buddies. His customers include not only Ultraman from the Land of Light, but also aliens from all kinds of planets. Wang Lei: Seven, listen to me. You'd better get on good terms with these aliens. They'll be a huge help to you in the future. Seven: Oh, okay. After Seven arrives on Earth: Damn, they're all familiar faces! Everyone, do me a favor and stop trying to invade. I've got this place covered! Pitt alien: That little boy from back then has grown into a young man! Jack: Nackle, we're old friends. You're my dad's drinking buddy, so do me a favor and don't cause trouble. If my dad finds out you mean his daughter-in-law harm, do you think he won't come charging out of the bar and wipe you out? Nackle thought to himself: Your dad and I came up with this scheme together. Do you think I'm going to do you a favor? Leo: Seven, you're getting revenge! Revenge for when you used to pin me down and beat me, and for ramming me with your wheelchair. You bastard! Seven: No, absolutely not!
