The Hoshizora Ranch (星空牧場 Hoshizora bokujō?) is a ranch located in the south of Hisakata, the primary location of the Guardian Angels Of The Sky series. The Hoshizora Ranch is owned by Yuuki Kouki and Yuuki Mitsuko, Yuuki Ririan's parents. The ranch is located in the Nanko Ward, of which it covers most of its space. Even though also caring for other animals, the Hoshizora Ranch is mainly a horse ranch.
- The ranch's name comes from the Japanese 星空 (hoshizora?), which means "starry sky".
