High schooler Nozomi Koiwa wakes up and discovers she’s lost her memories...and a whole lot of height. Now the size of a soda can, she flees from a feline assault into the disgusting den of Yume Okubo, a drunken shut-in NEET who’s terrified of people and hasn’t been outside for months. Between falling beer cans and deadly insect traps, Nozomi survives long enough to convince the airheaded Yume that she’s a figment of her imagination who’s come to save her from hitting rock bottom...all while investigating how she ended up funsized. But despite their differences—height, brains, and otherwise—each half of this quirky combo might just be what the other needs!
Now having met another mini-person who’s even smaller than she is, Nozomi is more eager than ever to find clues about her short stature at the shrine in the mountains where she first awoke. Problem is, one small step for man is a perilous journey for Nae and Nozomi. Meanwhile, Yume faces a daunting trial (for introverts) back home-getting a delivery and answering the door. But when she stumbles upon Nozomi’s cardboard abode, she begins to piece together that maybe, just maybe…Nozomi isn’t a figment of her imagination after all.
