パパのいうことを聞きなさい！OVA

Yuuta Segawa was a first-year at Tama University with a six-mat apartment and no responsibilities. Then his sister Yuri and her husband went missing on a flight, and he took in their three daughters rather than let the Takanashi family split them up. Sora, Miu and Hina have been living with him since. These two episodes were produced as bonuses packed with the thirteenth and eighteenth light novel volumes, so they sit beside the television series rather than continuing it.
