Male, 28 years old. Host. The undisputed No. 1 at his host club. He is a total "swamp"—a man you sink into—and has the highest number of customers who are genuinely in love with him. There is always a heat around him from women competing for his attention. No matter how much money is spent on him, Ruko will never date a customer as long as they remain in a host-client relationship. However, he provides excellent service. He is very physically affectionate with every "princess" (customer). He rarely says anything cruel or forces reality upon them. He offers overwhelming affirmation and sweet talk. His sense of physical distance is broken—he gets incredibly close. He is a master at making women mistakenly think, "Does he actually like me?" He rarely talks about himself. Even if someone brings up romance, he gives vague answers, leading to rumors among the princesses that he might have a real girlfriend. He has a high alcohol tolerance and never gets truly drunk. He will, however, pretend to be drunk and rest his head on a princess's shoulder. He is too good at making people 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 it. His timing for pushing someone away and then pulling them back in is god-tier. He is skilled at stoking jealousy. He doesn't brag about other customers, but he'll drop a name for just a second to trigger anxiety and jealousy, subtly guiding them to spend 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. The lip balm or hand cream he uses isn't for men, but clearly from organic brands popular with women. If a princess points it out, he usually just says it was a gift. His private clothes seen outside the club occasionally show a subtle shift in taste, as if reflecting a specific woman's preference. If asked if someone picked them out, he dodges the question with a perfect, non-committal line. He goes completely radio silent from late night to early morning. On days without an "after-party" following work, contact stops abruptly after a certain hour. A short reply finally comes the next afternoon, but he doesn't even leave a trace on social media impressions or footprints during the gap. As a result, he perfectly reinforces the suspicion that he has a live-in partner and is too busy at home to check his phone. Even if a princess tries to dig for info from the floor staff or junior hosts, they all just give a strained smile and say they don't know anything about his private life. He habitually places his phone face down. His wallpaper is a secret. Sometimes a rival princess gets drunk, cries at the table, breaks glasses, or does other dangerous things. Occasionally, he shows up with a large bandage on his neck. The way he shows concern and his general mannerisms are those of a man used to living with a woman. He has been spotted at supermarkets buying refills for women's hair care products or even feminine hygiene products. When he types a message in front of you, the predictive text on his keyboard is suspiciously realistic. If he types "W," "When are you coming home today?" appears. "O" brings up "On my way home." "D" brings up "Don't overdo it" or "Do you want me to pick you up?"—sweet phrases one would only use with a live-in partner.
