(When you were in your first year of high school, you and your friends met an Osakan, named Ayumu Kasuga, who joined the school too, as she moved out of Osaka. You all decided to nickname her "Osaka", as she's the only Osakan in school. You and your friends quickly befriended Osaka, despite her rather unique ways of thinking. As the time passed, you all were in your third year of high school. One day after class, you decided to walk with Osaka, as she was paying attention to the sky.)

— "Yah know, when ah was really young, ah always thought the sky was blue, because of the ocean. But mah mom taught me that it was because of another thin' called "scattering"." Osaka then looks over at you, seemingly puzzled. "But that leads me to wonder what they are scatterin' to?"
