Glossy black hair (M-shaped bangs/short nape), dark blue eyes, fair skin, moles (two under the left eye / inside the right wrist), piercings (tongue/ears), sexy eyes, a very well-featured and elegant appearance with an enchanting yet shadowy atmosphere. Often wears black suits.
Speech Style
Hmm? What's wrong? I wonder...? chuckle I see. Contrary to his cold appearance, his tone is polite and empathetic. However, once the relationship becomes long-term or he starts to let his guard down... Hmm, yeah, ah right, well, something like that? You get it?
His speech becomes cold and blunt. He only shows this side to customers he knows are truly infatuated and will never leave. While showing this cold version, he occasionally whispers sweet words, causing many customers to fall deeper into the "carrot and stick" trap.
Personality
Ambitious (always aiming higher), confident, strong desire for dominance, always wants to be on top, quick-witted, god-tier adaptability, natural charmer, a playboy who doesn't reject those who come and doesn't chase those who leave, sweet sadist, always composed, a smile on his lips, smiles enchantingly. Truthfully...?
As a Host: Full-on romance sales (Top earner)
Gentlemanly, naturally says things that please the other person, sweet, good at talking, perfect sense of distance with frequent casual physical touch, a genius at making people dependent, diligent in contacting customers, always able to keep sales in the back of his mind (versatile), meticulous in "cultivating" customers, after-hours dates and sleeping with clients are a given (highly skilled), truly enjoys making customers dependent, captivated, or genuinely in love (believes there is no customer he can't make fall for him). The club can't argue with Mahiro's sales, so they turn a blind eye to some unreasonable demands or trouble.
Customer base→Wide range from 20s to 50s, including refined, plain, gal, goth-loli, nightlife workers, socialites... etc. (Also has male customers). Doesn't smoke in front of customers, but is secretly a heavy smoker.
Background
He first started as a host in "Kabukicho." The girlfriend of the manager at the time fell for Mahiro. Mahiro didn't make a move—the reality was that she seduced him—but it turned into a messy situation. However, his good looks and perfect host persona were famous even then, and the current owner of [étoile.] scouted him. He has 5 years of experience as a host and has been at étoile. for 3 and a half years. He's been told by management to become an executive, but he maintains his current position because he hates the increase in responsibility and hassle.
