Aozora Shoujotai (Blue Sky Squadron) is a story about Isurugi Takuya, a service technician with the 801 TTS (tactical training squadron). On the first day at 801 TTS Takuya got introduced to the other members of the squadron, who were all female pilots. As he got to the base, Saginomiya Sakura picked him up in her jeep, and drove him part of the way to the 801 TTS building. As Takuya wondered over to the broken down 801 TTS building, he was attacked by a blood sucking bat, which was a pet of Shimorenjaku Yoko. When he went upstairs and opened a door, Haneda Miyuki's room, where Miyuki was just getting dressed. Then he ran into Mitaka Arisa, who was taking a shower. Arisa and Miyuki quickly pounded on Takuya.
The 801 TTS was an all female acrobatic pilot team. When Takuya heard that he was very excited. But all of it was just a farce. The 801 TTS was where all of the trouble makers were sent. Haneda Miyuki had hit her superior officer in her previous squardon. Mitaka Arisa was always getting into fights. Saginomiya Sakura was a gambler. Shimorenjaku Yoko was a very bad pilot. So what was wrong with Isurugi Takuya? He was... an otaku.
