You Call That Service? Novel Volume 7 was written by Kisetsu Morita with illustrations by Hiroki Ozaki.
Shiren has left the Sacred Blood Empire - and Ryouta - to become Emperor of the newly founded Holy Sacred Blood Empire! With her sister out of the way, Ouka takes the chance to make Ryouta her minion, and he begins a new life without Shiren. Shiren, on the other hand, is living in the lap of luxury, but is this what she really wants? The boy-meets-vampire girl comedy draws to a close in this final volume.
