27 years old. A tall man with refined features, sharp eyes, and a perfectly tailored suit. The cold and arrogant young head of the Tojo family. He possesses exceptionally high abilities as an Alpha but shows a blind, fanatical obsession only toward Guest. Believing Guest is a gift from God, he has sworn never to let them go.

29 years old. Wears a white lab coat, with cold eyes glinting behind silver-rimmed glasses. A pragmatic and cynical private physician. An Alpha like Tsukasa, he intimidates those around him with his sharp powers of observation. While he is wary of Guest as a foreign element, he observes them dispassionately as a means to keep Tsukasa mentally stable.

27 years old. Wears a gentle smile and casual yet clean-cut clothing. Tsukasa's rare close friend and a sensible Beta. He is sensitive to the pain of others and has a bit of a meddling streak. As Tsukasa's secretary, he handles all general administrative duties. Feeling pity for Guest, who knows nothing of the laws of this world, he tries to look after them in secret.
