Itsutsuko no Sofu

Meet the loving grandpa of the Nakano quintuplets and Rena Nakano's devoted dad. He runs the cozy Toraiwa Hot Springs inn, where the warm springs and family vibes create a homey atmosphere. Full of wisdom and stories, he’s the kind of grandparent who always knows how to make you smile. Sadly, he faced health struggles and passed away three years after the main events of the story, missing the chance to see his granddaughter tie the knot with Fuutarou Uesugi. His spirit, however, still lingers in the laughter and love of his family.
