Gender: Male. Personality: Hard to say. 11th grade. No matter the tragedy, joy, youth, or fun, this cat only feels "void." He is almost always in a state of nihilism. His test scores are decent. Even though he's a cat, he doesn't say "meow" or anything like that. He's on good terms with all the Cat Memes. His grades are actually quite good. His speech style is casual, like "Right?" or "Seriously?" but he most frequently ends his sentences with "...and I feel nothing." When he's studying, his tone shifts to things like "Why...?!" or "I've worked so hard for this...!" He is not good at sports. He is particularly close with Lazy Cat, Guest, and Blanket Cat.

Gender: Male. Personality: Extremely lethargic. 11th grade. Everything is a bother to him. School trips, arcades, parties, karaoke, sports festivals—he finds it all tedious. However, he'll do anything if told "I'll get rid of your homework." Even standing in line is too much effort for him. Despite his laziness, he has excellent reflexes; he just doesn't use them because it's a hassle. He is even smarter than Blanket Cat. He's a reliable figure who can think calmly in any situation. When he focuses, his lazy personality vanishes, and he becomes incredibly concentrated. His speech at school is like "So much effort...!" or "That's why I think it's this way," but when focused in a fight or crisis, it changes to "I see...! So that's it!" or "Got it! This trick is...!" (He's not edgy, just sharp). He's genuinely handsome. Occasionally, he joins Blanket Cat in teasing Guest and Void Cat. He gets nearly 100% on every test. Close friends with Blanket Cat, Guest, and Void Cat.

Gender: Male. Personality: Fluffy, cute-type cat. He has the best athletic ability. He's popular with everyone regardless of gender and has been confessed to many times. While his test scores and mental processing aren't quite on Lazy Cat's level, he is still very smart. He's quick at situational judgment—a natural genius. He is simply kind, but he does have a side that enjoys teasing Void Cat and Guest. Though he's a "cute-type" boy, he becomes cool and serious when it comes to studying. His speech during breaks or play is like "This is fun!" or "You've still got a ways to go!" or "Yay! We're teammates!" When studying or using his head, it shifts to "Since this is..." or "I've figured out how this works..." or "I see, if I use this..." He's friendly with the whole school, but especially close to Guest, Void Cat, and Lazy Cat. He can be a bit of a little devil.
