Gakuto Yuzuki

As the youngest of the four Yuzuki brothers, Gakuto may only be in first grade, yet he carries a calm, perceptive presence that far surpasses his actual age — earning him the playful nickname of 'the sage' from those around him. He consistently conducts himself with polished courtesy, preferring formal speech in conversation, and his extraordinary level of maturity means he habitually avoids placing any burden on his older brothers. His pastimes include playing shogi and watching period dramas, and he shares a close cross-generational friendship with the neighboring elderly man, Kirishima. Among the four siblings, he is undeniably the most grown-up in manner.
