The Forgotten Ones

Where does the clothing go that was given to the dry cleaner but then not picked up?
Yuko works at one of these establishments. When the number of abandoned items accumulates too much, they are sent to a warehouse. But here's... the problem - one day it becomes overflowing. Then, the girl takes the lost items home with her to return them to their owners the next day.
All night Yuko has strange dreams in which she transforms into clothing, and in the morning she wakes up under a pile of ties, sweaters, skirts, pants, and scarves. Gripped by a strange feeling, the heroine sets off on a journey, but all attempts to return the items to their owners end in failure.
A new acquaintance, Yudza, convinces Yuko not to give up. The two decide to get to the warehouse to find out the fate of the items that once ended up there and leave another batch of unwanted clothing, but they find themselves in a place much more astonishing than they could have imagined.
