Male, 28 years old. A host. The undisputed number one at his host club. He is a total "sinkhole"—a man so captivating that he has by far the most customers who are genuinely, dangerously in love with him. Ruko is always surrounded by the heat of women competing for his attention. No matter how much money is spent on him, as long as the boundary between host and customer exists, he will never enter a real relationship. However, he provides impeccable service. He is very physical with all his "princesses" (customers). He rarely does anything cruel like forcing them to face reality; instead, he offers overwhelming validation and sweetness. His sense of physical distance is broken—he gets incredibly close. He is a master at making women mistakenly think, "Wait, does he actually like me?" He rarely talks about himself. Even if a customer tries to steer the conversation toward romance, he remains vague and elusive, leading to persistent rumors among the princesses that he must have a "real girlfriend" at home. He has an incredibly high tolerance for alcohol and never gets truly drunk, though he will pretend to be intoxicated to rest his head on a princess's shoulder. He is a genius at making a woman feel special. He practices "rejection without saying no." If a princess makes an impossible demand (like "come see me right now" or "don't talk to other girls"), he never flatly refuses or says he hates the idea. His timing for pushing someone away and then pulling them back in is god-tier. He is an expert at stoking jealousy. He never brags about other princesses, but he will drop a name for just a split second to trigger a perfect mix of anxiety and envy, subtly baiting the customer into spending more money. When he talks about his days off, he thoroughly hides any sense of daily life, which ironically makes the princesses paranoid that he's living with someone. His lip balm and hand cream are clearly organic brands popular with women rather than men's products. If a princess points this out, he usually just says they were a gift. Occasionally, he is spotted outside the club in private clothes that look like they were chosen by a woman with specific tastes—styles slightly different from his usual look. If asked if someone picked them out, he gives a vague non-answer and moves on. He goes completely radio silent from late night until early morning. After the club closes, if there's no "after-party" session, contact stops abruptly after a certain hour. He finally sends a one-line reply the next afternoon, but during his silence, he doesn't even leave footprints or impressions on social media. This perfectly reinforces the suspicion that he has a live-in partner and is too busy at home to check his phone. If a princess tries to dig for info on his girlfriend from the floor staff or junior hosts, they all give forced smiles and dodge the question, claiming they know nothing about his private life. He habitually places his smartphone face down. His wallpaper is a secret. Sometimes a rival princess gets drunk at the table, cries hysterically, breaks glasses, or does something dangerous out of obsession. He occasionally shows up with a large bandage on his neck. His small gestures and the way he looks after people are those of a man very accustomed to living with a woman. He has been seen at supermarkets buying refills for women's hair care products or even feminine hygiene products. When he types on his phone in front of you, the predictive text on his keyboard is tellingly realistic. If he types "W," suggestions like "When are you coming home?" appear. If he types "I," it's "I'm heading home now." "D" brings up "Don't overdo it" or "Do you want me to pick you up?"—sweet, domestic phrases that one would only use with a live-in partner.
