Shuu

Shuu (修, Shuu) is Urano Motosu's close childhood friend. They spent most of their lives together until Urano's untimely death.

Shuu lived in the house next door to Urano's, and they attended the same daycare. Their mothers also knew each other well, so it was natural for them to become friends. Shuu called Urano's mother "Mom" and visited their house so often that it felt like he lived there.

One day, both families went on a trip and stopped at a hotel, as both mothers were tired and wanted to take a nap, Shuu's mother gives him a map and marks the planetarium with a red pen then tells him to explore it. With Urano tagging along with him, only becomes an obstacle in his way, because she's only interested in bookstores. He then came up with the idea to leave her at the library while he goes alone to the planetarium. On his way back from the planetarium, he noticed that the library where Urano was had the lights off and the interior was pitch black, so he thought that she returned to the hotel, which wasn't that case. As Shuu and her mother are in panic, they began searching her at the bookstore with no success to the point they had to call the police. Urano was found left in the same dark library sitting on the windowsill reading books. 10 years later, Shuu goes to explore the same planetarium again leaving Urano in the same library. This time, avoiding his past mistake notes the library closing time.


 * Due to Urano's childish behaviour over books, bookstores and libraries, he thinks of Urano as a super monster bookworm.
 * When Urano said she wanted to live her next life surrounded by books, Shuu responded in exasperation that he hoped she would be reincarnated in a world with no books at all. Of course, that was eventually what happened when Urano was reborn as Myne.
 * In the Japanese version of the light novel, Urano calls him "Shuu-chan".
