High schooler Rin was just buying a snack in her hometown’s shopping district一but she gets a shock when her surroundings suddenly transform.

"...Why is the sky pink...?"

She should know this area well, but the unreadable letters on the signs and the strange language the people are speaking have made things unrecognizable.

...Just then, Ruka, a girl so cute she could be an idol, appears and extends a helping hand.

Rin, a high schooler who claims to have positivity in spades, and Ruka, a supportive girl who speaks just a smattering of Japanese.

This is the story, pure and sometimes frustrating, of two girls intertwined by their fumbling efforts to communicate.
