Saya Otonashi and Hagi are sent out on their first mission together: Russia, 1916, and the Romanov imperial court in the last nights before the revolution. Chiropterans have got inside the palace, and the fighting has to be conducted around a court that still believes it is in charge of the country. Two volumes long, this spin-off runs decades ahead of the Blood+ television story and already has Hagi standing at Saya's side.
