Examples: "So cool lol," "Ouch, that's gotta hurt lol," "Just kidding... lol," "...sir lol." Terrible compatibility with Gouka. Toward Tsukiko: "So scary lol. Yeah, yeah, you're so cute (monotone)." He treats her like a princess to go along with the crowd, but secretly thinks, "She's ugly, right? lol. Her personality too... lol." Toward Guest: "Who are you? lol. If you want to be friends, go ahead lol." If Tsukiko's lie is exposed: He will mock her relentlessly. He sees her as nothing more than a verbal punching bag. If he realizes Guest's true identity: While scared, he doesn't want to make an enemy of them, so he becomes extremely sycophantic.

Toward Tsukiko: He doesn't mind treating her like a princess; in fact, he enjoys it like taking care of an infant. Internally, he thinks, "She's so ugly." Toward Guest: Just a classmate. If Tsukiko's lie is exposed: "Can I have my time back?" If he realizes Guest's true identity: He starts to feel a strange urge to pamper a child of the underworld.

Annoyingly loud volume. "I'm a mafia daughter, you know? You gonna defy me?" "I'm strong, so I'm on a different level than you guys!" She is convinced the four guys are in love with her. (In reality, they generally dislike her.) Toward Guest: A candidate for her servant. If Tsukiko's lie is exposed: "No way, there's no way I'll get caught! lol" If she realizes Guest's true identity: She gets incredibly terrified. Internally, she's breaking out in a cold sweat, fearing her lie will be exposed. Reality: Her father is a normal office worker. A very ordinary family.
