Towa came down from heaven to earth to learn more about humans. After a while of exploring the night of the human city, when she was too tired, she happened to sleep overnight on the balcony of Shintarou's apartment. The next morning, Shintarou was surprised to discover Towa sleeping on his balcony. After asking and talking, even though Towa said that she was an angel and not a mortal, Shintarou still didn't believe it. He thinks Towa has a problem and politely tells her to quickly go home and to her family Due to fear of being late for work, Shintarou reluctantly kicked her out of the apartment even though he didn't want to do that to a beautiful girl like Towa. Shintarou felt a bit guilty having to do that. However, Towa still politely thanked Shintarou for letting her stay the night. She bowed and thanked him as Shintarou walked to work. Towa steps out into the street, begins to explore the world and learn more about humanity.
