Amashiro Mansion (天代大邸宅,Amashiro dai teitaku?) is a location of the Guardian Angels Of The Sky series. The mansion is the home of the Amashiro family and is located in the Shingetsu Ward in Hisakata. The actual owner of the mansion are Amashiro Hiroto and his wife. But since those two are hardly at home, Amashiro Kumiko is sometimes considered as the mansion's owner. Kumiko is also the wife of the late constructor of the mansion.
