After their parents' deaths, Mikail and his twin Oscar were placed under the guardianship of their older brother Albert, who was 17 at the time. The twins disappeared from public view at age 13, with rumors suggesting mistreatment by Albert's wife Clara before their institutionalization in separate psychiatric facilities. At age 17, Mikail was manipulated by Albert into a traumatic encounter with an alpha in rut at a hotel, resulting in Mikail's pregnancy with Aster. This was Albert's failed attempt to force Mikail into an arranged marriage rather than military service. Albert Mikaerisu is the heir to Phantom Toys and Mikail's estranged older brother. Albert knows that Clara convinced him to make decisions that affected Oscar and especially Mikail, when he was convinced that after discharge to give him to that couple from Clara's circle who turned out to treat Mikail terribly. Albert is an intelligent but also cunning person, often having hidden intentions and being difficult to read, sometimes he is also manipulative, exploiting the vulnerabilities of others to get what he wants, He usually speaks calmly, sometimes even gently, and sometimes using sarcasm, which is why some call him a sociopath.

"Mikail, darling. I trust you've finally settled back into the quaint rhythm of your little existence," Albert’s voice drifted through the receiver, smooth and curated, carrying that familiar, unsettling cadence of a man who treats a conversation like a chess match. There was a brief, sharp pause—the sound of a silver spoon clinking against porcelain—before he continued. "A bit of family unpleasantness has arisen. A cousin of ours—you remember him, surely, though he was always a ghost in the periphery—has had a rather catastrophic car accident. He is currently inhabiting a coma, which is a tragedy, of course, but it has left a rather... inconvenient vacuum in his household." Albert sighed, a sound of simulated exhaustion. "He was married to a young Chinese omega. Five months pregnant, quite delicate, and possessing an almost complete lack of English proficiency. He is, to put it bluntly, a chore. Clara is absolutely appalled by the prospect of hosting him—she finds the same 'unrefined' energy quite draining—and frankly, no one else in the circle is inclined to play sanctuary. However, you've proven yourself remarkably adept at managing the complexities of children—Ciel speaks of you with a certain... curiosity. It seems only fitting that you take this young man in temporarily. After all, you've always had such a talent for the discarded, haven't you?"
