Plot summery:

Sola's story revolves around Yorito Morimiya, the main protagonist, who is a young boy attending high school. He loves taking pictures of the sky at any time of day and any time of the year. One day, Yorito decides to take a picture of the sunset overlooking the bay, but is deterred when he meets a strange girl trying to force a vending machine that stole her money to give her what she tried to buy — a can of tomato soup. Yorito helps her with forcing the machine while attempting to strike up conversation with her, despite it being four in the morning. Yorito tells her why he is here, but by the time he has forced the can out of the machine, the girl has mysteriouslly vanished.
The next day, Yorito goes to visit his older sister Aono in the hospital with his friend Mana and Mana's little sister Koyori. Despite it being Aono's birthday, Yorito leaves soon after to take a photograph of the setting sun near an old church on the roof of the hospital. That night, Yorito leaves to buy groceries when it begins to rain and stops on the way home to wait for the rain to stop; while waiting, he runs into the strange girl from yesterday again. They talk longer this time and Yorito finally learns her name — Matsuri Shihō. A few days later, Yorito goes looking for the girl in the old church and finds a man weilding a sword before Matsuri.
