A Crossover Restaurant, Starting with Demon Slayer

Food + crossover, one heroine. The overworked FrostNova fan Xu Yuan wished for a certain character, but the deaf Raven Goddess turned him into that very character instead? And now he has to run the Yuweiju restaurant? She even gave him her bubble? Wait, isn't this blatant knockoff infringement? Well, a knockoff doesn't have to be worse than the original. Besides, all the customers come from other worlds, so there are no 996 workdays or KPIs, and he has enough power now. Maybe he can make up for a few regrets? If all else fails, he can go home and cling to An Yu's coattails. A chef by choice, helping out now and then, and often now and then. Yuweiju welcomes you today, too. (Currently featuring Demon Slayer + Arknights + Marvel, with FGO under consideration. Feel free to discuss other series you'd like to see.)
