Kono Aozora ni Yakusoku wo

Wataru Hoshino lives with four other girls and their teacher on South Sakojima Island.

Life on South Sakojima Island changes when new student Sawaki Rinna becomes the center of attention.

Wataru reminisces about meeting Miyaho.

Wataru gives some insight about Rokujou Miyaho.

Wataru was lying by the river bank when he came across girl with a blank stare. When Wataru called out to her, she ran away into the middle of a sugar cane field and ended up dropping her straw hat. Her name is Shizu Fujimura. When he meets her again, he comes to understand her situation but...

Shizu has gotten used to life in the Tsugumi dorms but she didn't score very well on her test so she must take another exam. Shizu dreaded taking this so she ran away from it. Saeri was the one who decided to do this so Wataru is beginning to wonder if it was a good idea to have Shizu live in the Tsugumi dormitory.

Wataru and Issei talked about many things including bringing Issei to the school and living in the dorms. At the same time, Umi was also talking to her dad, Katsuhiko. Both of them kept the fact that they are sharing a life together in the dorm a secret.

The fact that Issei is living in the dorms was leaked by Wataru. It was said that he left the dorm but that was denied. So Umi was talking to her dad, Katsuhiko, about her relationship with Wataru but was hesitant in saying too much. What will become of Wataru and Umi's relationship?

The principal and vice principal at Takamitsuka High School are eager to demolish Tsugumi dormitory. For this reason, there were people inspecting the circumference of the dorm. Wataru and Saeri started investigating when this was suggested by the principal and vice principal.

Wataru and Saeru were investiaging on what the principal and vice principal of Takamitsuka High School had up their sleeves. However, Wataru was cross examined by the vice principal about a embrace he had with a girl in front of a hotel. An emergency staff meeting was held to decide on his expulsion. What will be the fate of Wataru and Takamitsuka High School?

Naoko and Wataru met when he was still a middle school student. He heard that she was the prettiest girl on the island and wanted to try to win her over again. Naoko disregarded the fact that he insisted on the date but when he got the chance to say something, what did he do?

Tsujisaki, who used to like Naoko, appeared in front of Wataru and Naoko. Tsujisaki was the original student of Tsugumi Dormitory and is currently a student at Yatsuhashi University but it’s said that heavenly bodies appear on Minami-sakōjima island. Wataru sees him...

March 21st, 3:00pm - One teacher and six students gathered at Takamitsuka High School's Tsugumi dormitory because none of them wanted to be separated. The promise that was made under the blue sky was carried out. The last year of the Tsugumi dormitory and the tale of the last seven people is to never be forgotten by us.
