The sports festival kicks off with high-octane rivalry between Classes C and D. Harry and Togo steal the show during ball toss, Harima and Hanai sprint like maniacs in the three-legged race, and Ichijo and Lala go head-to-head in a tug-of-war that shakes the field!

Someone draws a heart with Harima and Eri's names on the classroom board. Enraged, Harima lashes out—but when Tenma casually says she supports his relationship with Eri, it hits him like a truck: she never liked him back.
