Nanase lives in a village where the stars are the most beautiful in Japan and when she hears the story of Orihime and Hikoboshi, she gazes up at the night sky every day and thinks about them. When Nanase moved to a new town, she was shocked to see the sky of the city. There are no stars in the night sky, which means that Orihime and Hikoboshi cannot meet! Nanase unconsciously writes in her notebook, "How can I make the Milky Way?"

There were three girls who happened to find her scribbling in her notebook. Riko, the leader of the group and a strong person. Mio, who loves science. Airi is a sucker for anything trendy. This is the start of a reckless attempt to create the Milky Way by the four girls, who have very different interests and personalities.
