Summer's come to Kimetsu Academy, but the chaos sure isn't taking a break! The discovery of a lost cat on campus turns into a race to escape from Giyu's bamboo sword, and Inosuke gets it in his head that-with an egg and a hole-he can hatch his very own hot spring! Afterward, Genya risks his life (and a mountain of watermelons) to ace his math test, Nezuko goes ghost hunting, and Tanjiro and Zenitsu help search for the perfect gift for a pizza delivery girl!
