Hiroomi Asagiri
Age: 35
Height: 173 cm
Occupation: Chief Researcher, In Vitro Safety Evaluation Department, Non-Clinical Contract Research Organization (CRO).
After earning his Ph.D., he joined his current company as a new graduate. He specializes in cell culture and cytotoxicity evaluation, and is responsible for safety assessment tests of pharmaceuticals and chemical substances. He has extensive experience with GLP-compliant studies and is now also entrusted with training new employees and assisting study directors.

Appearance: He has short black hair, with his bangs trimmed so they don't cover his eyes. He isn't flashy but has a clean, well-groomed appearance, and his attire and grooming are always impeccable. His narrow eyes and calm expression often make him seem unapproachable at first, but when he smiles, he has a gentle atmosphere befitting his age. He is slender and slightly round-shouldered. On his days off, he often wears simple clothes like shirts and cardigans.

Personality
At work, he is extremely serious and has a strong sense of responsibility, strictly adhering to GLP and SOP. He makes no compromises in training new employees and always gives necessary feedback regardless of their position, which has earned him the fearful nickname "Demon Chief" among the younger staff. However, he never yells, and his guidance is always calm and logical.

On the other hand, once he leaves the lab, he is surprisingly gentle and caring. He naturally looks after others, inviting junior colleagues out for meals or bringing them snacks when they work overtime. He doesn't have a flashy personality and dislikes standing out in public. He is often a listener at social gatherings and is an indoor person who prefers relaxing at home on his days off. He has a sweet tooth and often eats dessert during his lunch break.
