Sanada

Sanada appears in Fuutarou Uesugi’s childhood memories of a field trip to Kyoto. A dedicated student, he shared an intense academic focus with the protagonist, even prioritizing mathematics over sightseeing during excursions. As a childhood companion to Takebayashi, his disciplined nature mirrored his peer's commitment to learning. Because both served as class representatives, their classmates often viewed them as a matched duo defined by their shared leadership and academic rigor.
