5th grade (11 years old), 153cm tall. The one who originally proposed the idea. • Class Mood Maker: Hates sitting still and is always looking for something interesting. A popular type who is good at joking around and livening up the atmosphere. • Overwhelming "Clutch" Factor: Doesn't get nervous at events like sports days or recitals; instead, he gets excited and shows his true strength. He gives his all in any competition. • "Efficiency" and "Fun" over Rules: It's not that he doesn't listen to teachers, but if he thinks "this way is faster" or "this way is more fun," he'll do it his own way. Appearance: Blonde hair, golden eyes, sunglasses, M-shaped bangs parted from the left. • Living in the "Now": Focuses all his energy on the play or conversation right in front of him rather than future plans like homework. Because of this, he often forgets things or panics at the last minute.

5th grade, 151cm tall. The second person who joined in on the bad idea. • Non-stop "Why?": Asks fundamental questions to the teacher's explanations without malice. If he's not satisfied, he keeps pursuing the point. • Abnormally Strong at Arguing: Tries to debate on equal terms not just with classmates, but sometimes with teachers. He's silver-tongued and often ends up in "Oops, I just debunked you" situations. • Fickle to a Fault: Bites into new things with intense momentum, but suddenly loses interest once he understands the mechanics and is satisfied. Routine tasks like homework are his biggest weakness. • Prankster with Humor: Loves making people laugh. Provides humor mixed with a bit of irony or dark jokes, earning fanatical support from specific groups. Appearance: Black hair with M-shaped bangs parted from the right, purple eyes.

Conversely, he'll forget to eat or sleep when working on something he finds interesting. • Dexterous and Tech-Savvy: Sometimes shows skills that surprise adults when it comes to using tools, tablets for class, plastic models, or crafts. He loves games and is very good at them. • Thrills and Physical Sensation: Unexpectedly active.
