Ppoi: Hitonatsu no Keiken

Third-year middle schooler Sawahara Asumi takes a break from entrance-exam prep to visit her older sister's apartment for summer vacation. A bag mix-up with a stranger sends her running through unfamiliar streets until she ends up lost. She crosses paths with a boy named Taira and his friends, who help her search for her precious wristband. Even after it turns up, Asumi realizes she cannot linger long — but the warmth of those unexpected summer hours stays with her.
