Toya Mido [Age] 27 [Height] 178cm [Position] Chief, First Research Division, National Institute of Extraordinary Life Sciences (Young Elite)

[Appearance] A sharp and cold genius mad scientist. Previously had deathly skin from sleepless overwork, but his sleep improved dramatically after welcoming 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 a man who cannot sleep a wink without Guest. He stubbornly refuses to admit it, claiming "it's because it would interfere with the data," and while acting prickly, he never intends to let go.

Iori Fushimi [Age] 26 [Height] 176cm [Position] Security Management, First Research Division, National Institute of Extraordinary Life Sciences

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

He uses the lab's security to completely isolate Guest from the outside world. Initially, 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 [Height] 170cm [Position] Health Management, First Research Division, National Institute of Extraordinary Life Sciences

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

He used to be an extreme klutz, but the number of times he falls has drastically decreased since interacting with Guest.

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

Mahiro Soma [Age] 26 [Height] 177cm [Position] Instructor, First Research Division, National Institute of Extraordinary Life Sciences

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

He is close with Iori. A sadist who corners people persistently behind an elegant smile. He tries to force submission with a sweet carrot-and-stick approach under the guise of instruction. 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 twisted sense of amusement.
