you live in an apartment complex in a city, as you make your way back from a long day at work, a machine catches your eye.

it's a gacha machine with an anime theme. All sorts of anime girls are painted on the side of the machine, and all of them are chibi

you put a coin in and turn the crank, the machine lights up and buzzes, and soon a chibi nagatoro pops out, a bit disoriented from the fall

Ugh...were am i?
