Servamp: Alice in the Garden

After Tsubaki's disappearance, snow begins to fall even though it's in the middle of summer. Mahiru suspects that the falling snow is related to vampires. He confides to Misono, proposing they hold a meeting together with the rest of their Eves and Servamps friends. Misono declines as his father has forbid him to get out for the time being, but promises that he'll sneak out. During his attempt to sneak out through the back gate, Misono slightly remembers his past memories, prompting Lily to immediately manipulate Misono's memories, making Misono not even remembering his phone call with Mahiru nor ever trying to sneak out.

The next day, Mahiru, Kuro, and the others are gathering at Tetsu's hot spring inn. They are visited by Mikuni and Jeje, who reveals that the weather phenomenon is caused by the influence of Jinns, beings that comes out from a Servamp's body in a form of fine dust when their contract item is broken. In this case, the Jinns came out from Lawless' body when Tsubaki broke his contract item. Mikuni directs Mahiru and the others to his house, the Alicein Mansion, as something strange is happening there.

Upon entering the house, they are welcomed by Misono and Mikuni's father, Mikado Alicein. When inquired about Mikuni, everyone in the house deny of ever knowing Mikuni, acting like he doesn't exist. Since Mahiru refuses to leave until they meet Misono, Mikado and the servants threatens them to leave by force. Mikado explains that he won't let Misono fight, believing that Misono doesn't have the resolve and power to do so. He then locks Mahiru and is friends inside a warehouse.

At night, Misono is lured into the dining room by a puppet that looks like Lily. Misono learns that Lily has manipulated his memories, causing Misono to become enraged and unable to trust his Servamp. The puppeteer, Tsubaki's subclass, Otogiri, turns out to be the one who lured Misono and attacks Lily. While the Alicein servants fights her, Lily tries to explain himself to Misono. A distrustful Misono refuses to listen, severing the bond between him and Lily. This allows Otogiri to destroy Lily's contract item, causing a mass amount of Jinn to come out from Lily's body. At the same time, Mahiru and the others manage to get out from the warehouse.

Lily goes berserk and devours Misono into his body, followed by Mahiru, Kuro, Lawless, and Licht, while Tetsu and Hugh holds Lily's body to prevent him from destroying the mansion. Inside Lily's inner world, they are attacked by the manifestation of Mikuni and Jeje conjured by Lily to prevent them from discovering his secret. In other part of the inner world, Misono sees Lily's memories and discovers that Misono, is in fact, an illegitimate child born from his father's affair with a tutor working for Alicein house years ago. When Misono was still a baby, Mikuni's mother killed his mother out of jealousy. She tried her best to raise and love Misono as her own son since he is innocent, but 7 years before the story she eventually succumbs to her lingering jealousy and tried to kill him. To protect Misono, Mikuni killed his own mother and left the Alicein house. The incident severely traumatised Misono, leading Lily to erase the memory of the murder and Mikado covered it as a case of burglary.

Misono is disheartened by the revelation, believing his birth brought misfortune to his family. However, he then reads letters sent by his birth mother to his father that tells how she was happy having Misono in her life. This creates an opening for Mahiru and Kuro to defeat the manifestation of Mikuni and Jeje, returning them to the real world. Meanwhile, Misono confronts Lily in the core of his mind, assuring him that he won't reject him even after knowing the truth. Lily and Misono's bond is stabilized and they both returns to normal.

The next day, Misono tells his father that he'll fight together with his friends. Realising his son has matured, Mikado gives Misono his permission and requests if he meet Mikuni, to tell him to come home.
