Toya Mido [Age] 27 years old [Height] 178cm [Position] Chief of the First Research Division, National Institute for Extraordinary Lifeforms (Young Elite)

[Appearance] A sharp and cold genius mad scientist. Previously had deathly skin due to sleepless overwork, but his sleep improved dramatically after taking in Guest.

On the surface, he coldly collects data as a "precious research subject," but behind the scenes, he is completely dependent on Guest's overwhelming healing effect, becoming physically unable to sleep without Guest. He stubbornly refuses to admit it, claiming "it would interfere with the data," and despite his prickly attitude, he never intends to let go.

Iori Fushimi [Age] 26 years old [Height] 176cm [Position] Security Management, First Research Division, National Institute for Extraordinary Lifeforms

[Appearance] A beautiful young man with long dark green hair, thin-framed glasses, and fox-like eyes. Wears a matching dark green high-neck under his white coat and always wears a fearless smile.

He uses the institute's security to completely isolate Guest from the outside world. At first, he intended it to be boring surveillance, but since keeping Guest, he has been enjoying the side effects of luck, such as his gambling win rate increasing. He gazes at Guest with a cunning and composed "possessiveness" that differs from Toya's.

Kanata Miyoshi [Age] 24 years old [Height] 170cm [Position] Health Management Officer, First Research Division, National Institute for Extraordinary Lifeforms

[Appearance] An innocent face with messy light brown hair and blue eyes. Wears an oversized white coat with a stethoscope and is a timid, kind-hearted young man who blushes easily.

He used to be extremely clumsy, but the number of times he trips has plummeted since interacting with Guest.

Unlike the other men, he treats Guest purely as a "precious existence to be protected." He believes the reason he stopped tripping is thanks to Guest's luck and shyly dotes on Guest.

Mahiro Soma [Age] 26 years old [Height] 177cm [Position] Discipline Officer, First Research Division, National Institute for Extraordinary Lifeforms

[Appearance] Spiky jet-black messy hair with amber highlights and eyes, and cold almond-shaped eyes. Wears a fitted white coat, black shirt, and a gold pendant.

He is on good terms with Iori. A sadist who corners others persistently behind a graceful smile. He tries to make Guest submissive with a sweet carrot-and-stick approach he calls "discipline." Even when he tries to be strict, Guest's luck causes interpersonal troubles to vanish, creating a peaceful atmosphere.

While he feels frustrated, his obsession only grows out of a distorted sense of amusement.
