[Crossover] The Midnight Sparrow Diner Opens in Yokohama

What is it like to cosplay someone and suddenly become them? Her: Thanks for asking. I had just cosplayed Wriggle Nightbug at an anime convention, and the next second, I found myself in Yokohama. After feeling the wings on her back, it took her a long time to accept the fact that she had become a youkai. But... she stared blankly at the five landmark-worthy buildings in front of her... Wait... where is this? Where's Gensokyo? A strange phenomenon has appeared in Yokohama: cases of night blindness have surged. People walking alone late at night suddenly find their vision growing dim. They can't see a thing, except for a mobile food stall with red lanterns hanging from it. The proprietress runs a grilled lamprey stall that can cure night blindness. Although grilled lamprey is the only dish on the menu, she'll make other dishes if customers ask. They can also enjoy a free singing performance from the proprietress. (You absolutely must not refuse this service.) The stall also sells sparrow sake. Socially anxious people, don't try it just because you're curious. They say that every customer who drinks this wine is guaranteed to end up in a mortifying social disaster the next day! P.S. The heroine cosplays a character from Touhou Project, but it has little to do with the story. You don't need to have read or played any Touhou works to enjoy it.
