Volume 1

''It was the era of the supreme Russian Empire with financial power and vast territorial reign under the Romanov dynasty. Magnificent architecture and arts of multiple disciplines were abundant. However, under the rule of 14th Tsar Nicholas II, the Russian foreign policy began to fall and the faux-pas eclipsed the Romanov grandeur. The royal family consisted of - Tsar Nicholas II, Tsarvina/Tsaritsa Alexandra, Tsarevna Tatiana, Tsarevna Olga, Tsarevna Maria, Tsarevna Anastesia and Tsarevich Alexei. Another influencial member respected by the royal family was the High Priest Grigori. However, his presence proved to be the main cue for disbelief and riot against the Empire.''

Year 1916. Saya and Hagi reaches Petrograd. They have come to investigate the royalties following the trail of Diva. For that, they join in the orchestra group of Romanov Royal Academy.

In the academy, they get acquainted with Victor. Saya doesn't pass the test to make it as a lead player but Hagi draws everyone's attention instantly by his ingenious cello play (despite the fact that it was Saya who originally taught him to play the cello). Saya is allowed to hang around as a novice and sent to a private room to practice. There she meets a girl named Claudia who has come along with her brother, Vincent, for treatment from a good healer who resides in the Imperial household. As they get along with each other, they could hear the performance of the Imperial Orchestra beginning.

Elsewhere in the palace, the music floats into the ears of the young royalties too. Princess Anastesia urges Prince Alexei to accompany her to the orchestra but he is afraid that their mother might scold them. The princess gets another idea to have fun with stilts but their mother, Tsaritsa Alexandria intervenes. She snatches away Alexei from Anastesia, scolding her for her carelessness with her brother who is not as healthy as her. Grigori, who has accompanied Alexandria, stops her from scolding the princess and persuades the latter to be careful around Alexei. Grigori's pampering earns him a hug from the princess who runs off gayly after mocking her mother. Tsaritsa Alexandria confines Alexei to his rooms and drowns in anxiety herself when alone with Grigori. She vents out her worry about her son being limited by his illness despite being the only heir to throne. Suddenly, Grigory embraces the empress, assuring that he'll help her and Alexei and asking her to trust in him completely.

Saya and Hagi alight from the carriage, having arrived their rooms after the day-long rehearsal. Saya is a bit off since Hagi got chosen as an orchestra member and seems to have been savoring every moment (the smug expression written all over his face although he is reluctant to admit it). To cheer up Saya, Hagi reminds her that she too, has made a friend. Saya quickly switches to their objective, which in itself is a gloomy prospect and the two agree on finishing their mission as quickly as possible so that they can return home. As they walk into the house, they find a letter slipped under the door with a seal of Bordeaux. Saya and Hagi are reminded once again of their mission: to eliminate the existence of those who are no longer human.

Meanwhile, Claudia admits feeling quite good ever since she has undergone the treatment. Her healer is revealed to be Starets Grigori Rasputin who affirms Vincent that Claudia is doing well. Claudia accuses her brother for worrying too much while Rasputin steals a sly smile.
