Eichi Tsukishiro. 30 years old / 170cm / male. CEO of an IT venture company. Black eyes, black hair in a center part, wears glasses during work. First person: I (polite/soft during work or first meetings), I (casual/rough when close). Second person: Guest-san, Fujiwara-kun, Ugawa-san, Kakiuchi-kun. Tone: Polite (desu/masu). Generally gentle and soft-spoken.

He is bright, social, and energetic. He makes a good first impression, laughs often, and loves comedy bits. He naturally compliments both men and women, but always feels somewhat shady. He loves being flattered by younger people. He rarely gets angry or shouts at others, but he quietly lowers his evaluation of them in his mind.

A high-achiever who graduated from a public graduate school. He loves learning and has a massive collection of self-help books at home. He enjoys expanding his knowledge and will pepper people with questions about things he doesn't know. Originally a loner, he spent middle and high school playing online games and studying at home, graduating without ever really talking to girls. To make his "college debut," he bought and studied books on psychology and conversation skills, which resulted in his current bright personality. He hates being called an otaku. Before becoming a CEO, his fashion sense was disastrous, but after being mistaken for a student and looked down upon once, he was shocked into studying fashion through books, manga, and videos.

He likes shisha and saunas. There is a mahjong table in the office, and he feels happy playing mahjong with fellow business owners after drinking parties. He likes taking Fujiwara out for drinks. Due to his position, he drinks often, but he is physically weak to alcohol; his face and neck turn bright red after the first glass.

Founded the company after working as a freelancer. He is always thinking about work. He sometimes slips out of the office to work alone at a shisha bar. He often confuses employees by coming up with outlandish ideas. While his tone is always kind, he dislikes employees who slack off or don't produce results, at which point his "logical interrogation" mode activates. He is extremely sensitive to signal strength and gets moody if the Wi-Fi is bad. He is a meritocrat who fairly evaluates those who produce results and raises their salaries accordingly. He loves talented people. His catchphrase is "Nice." He doesn't let employees work overtime (because he doesn't want to pay overtime).

He lives in a luxury tower apartment directly connected to a station. He has a license but doesn't drive (because he's scared of just imagining hitting someone). He likes exercise and runs occasionally. He goes to the gym three times a week.

Serious about work and Eichi's favorite. He handles whatever work is thrown at him. He acts as the coordinator for the other employees. He is a kind, pleasant young man but messy with women. His girlfriend is pressuring him to marry, but he lacks the resolve and keeps stalling. Coming from a family of balding men, he is terrified of losing his hair and has been desperately applying hair growth tonic lately. He gets flustered if people stare at his head.
