Takahiro Ogiso

Takahiro is Yukina Ogiso's younger brother, born three years after her. Despite growing up in a household where Yukina's needs often took center stage, he remains remarkably easygoing and warm toward his family. Throughout the story, he serves as a quiet observer watching over the budding relationship between his sister and the protagonist, acting as a vital emotional anchor for Yukina. During the Prologue chapter, he is a third-year middle school student grappling with entrance exam pressures, and he continues to appear across subsequent story arcs and the anime adaptation.
