Rinka Urushiba works part-time as a waitress to support her father, who is unemployed. Her life in Tokyo appears to be reasonably regular on the surface, but when she mysteriously witnesses a flying penguin one day, her sense of normalcy begins to erode. Chasing it all the way to the top of a building, she comes across further shocks, including flying goldfish and another person—a student called Kyoutarou Azuma—who can see the unusual things as well. Rinka awakens as an esper with the power to phase through solid matter after passing out after a goldfish phases through her.
