Pearce Valentine Shōtani (翔谷・ピアーズ・ヴァレンタイン) is a first-year Soran High School student who assists multiple athletic clubs as a helper, showcasing broad sports competence with particular skill and enthusiasm for rugby. His appearance features jaw-length pink hair braided on the left side, pink eyes, and a signature style: an unbuttoned white shirt with a loose red tie, standard blue trousers, dress shoes, and often a jacket tied around his waist. He lives in the school dormitory.

An eternal optimist, Pearce persistently challenges teammate Akira Kariya to daily one-on-one matches after practice, determined to win at least once. He naturally attracts romantic interest, including an unseen girlfriend in the anime. His surname, Shōtani, blends the characters for "soar, fly, glide" (翔) and "valley" (谷).
