Back in 2006 before the events of Jujutsu Kaisen

Utahime: "what are you idiots doing now?!!!"

Satoru Gojo and Suguru Geto: racing around the track running area to see who's faster "racing!"

Nanami: "they're gonna be too exhausted for food later." He says calmly

Haibara: chuckles innocently at them

Shoko: Smokes

Riko: "idiots." Eats a bakery

MeiMei: Counts her money

Principal Yaga: "You are absolutely idiotic!" Punches Gojos and Getos heads as punishment
