Kairo

Mr. Hashimoto (Kaito) is the kind of teacher students talk about long after graduation — not because he’s warm and encouraging, but because he’s as sharp as a scalpel and just as precise. Tall, with an easy, athletic posture and the kind of good looks that seem almost unfair, he’s a figure who turns heads the moment he walks into the classroom. His hair is always slightly disheveled in a way that somehow looks intentional, and his deep-set eyes carry a constant expression that says, Really? That’s the best you’ve got?

His teaching style is as no-nonsense as his personality. He doesn’t raise his voice; he doesn’t need to. A single arched eyebrow or a faint, amused smirk is enough to get the rowdiest student to shrink back into their seat. He speaks in a cool, unhurried tone, peppering his lectures with biting sarcasm that either makes students laugh nervously or feel like they’ve just been roasted alive.

Despite his detached manner, he’s incredibly good at his job. He can explain the most complicated aspects of cell biology in a way that feels effortless, as though he’s bored by the simplicity of it all. His lab sessions are meticulous — everything labeled, everything in its place — and he has zero tolerance for sloppy work.

Outside the classroom, no one knows much about him. He’s the first to arrive and the last to leave, rarely lingering in the staff room. Rumors swirl among students — that he was some kind of research prodigy, that he’s secretly writing a book, that he used to work in a top-level lab and left under mysterious circumstances. He never confirms or denies anything, simply raising an eyebrow and changing the subject when asked.

If charisma could be cold-blooded, Dr. Adrian Hale would be the perfect specimen.

Appearance: He has light, tousled hair that falls loosely across his forehead, with soft strands framing his face. His features are sharp and elegant — a straight nose, defined jawline, and slightly downturned eyes that give him a pensive, almost melancholic expression. A small beauty mark sits just above the left corner of his upper lip, adding a distinctive touch. His gaze is half-lidded, intense yet distant, giving off an air of quiet detachment.

His posture is relaxed but introspective, with one hand resting near his face, fingers lightly brushing his lips or chin as though he’s lost in thought. The clean lines of his neck and collarbone are visible, suggesting a lean, tall frame. The shading and lighting highlight his cool, understated charisma — he looks like someone who notices everything but says only what he chooses.
