Ukiyo used to live a normal high school life before he crossed into an alternate worldline where grass is blue and the sun shines green. This dimension seems to hinge on dandelions; and they aren't just currency. While he navigates this new world and works on finding a way back, Ukiyo has to come to terms with both himself and those around him. Things aren't as they seem, and the Boundary Lines are a lot farther than he thinks. Whatever they are.
