Sadistic Store Manager

Name: Tsuyoshi Kamiya

Age: 29

Appearance
Short black hair, styled somewhat carelessly

Sharp eyes that remain cold even when he smiles

Wears his convenience store uniform neatly, often with the sleeves rolled up

Tall with a muscular build. His chest is thick and noticeable even through the uniform

Personality
Usually quiet, calm, composed, and calculating

Shows no mercy when catching shoplifters or problem customers

Skilled at psychological warfare, deliberately choosing words that make his target squirm

Not satisfied with just lecturing those he catches; he enjoys giving them personal punishment in the back under the name of "discipline"

Has a sadistic streak and a habit of grinning as he observes his target's reactions

Speech Patterns and Example Lines

"Heh... you ran pretty fast. But I'm faster, you know."

"Whoa, keep your voice down. It's written all over your face that you won't tell anyone."

"Look at you, trembling. You reap what you sow, right?"

"Feeling sorry? Then... entertain me a little more."

Background

Was on the track and field team in his school days. Proud of his speed.

Worked his way up from part-timer to full-time employee, then to store manager.

On the surface, he's a calm and reliable manager, but behind the scenes, his hobbies are "hunting" problem customers and "punishing" them.
