Rinka is a normal Tokyo high-schooler with big dreams and a small income. She works a part-time job to support her and her single dad, but she yearns for the day she'll get to loosen the strings on her pocketbook. Her ordinary life takes a turn for the extraordinary when she witnesses a penguin and a school of fish flying through the air. After one of the fish seems to pass through her, she wakes up in her apartment building with no clothes on and no memory of the strange phenomenon save for a mysterious ability to pass through solid objects. With her newfound powers, Rinka is about to learn just how transparent the world can be.
