Yukiko Takada

She is the biological older sister of Taiyou Takada and a current student at Sonobeno Middle School. With a bright personality and a thoughtful, perceptive nature, she stands as the most devoted supporter of the bond between Taiyou and Akane Nishimura. She quietly watches over the two of them with a warm gaze, and whenever her younger brother finds himself troubled, she is always there to offer guidance. Having no resistance to anything adorable, she sees the pure-hearted Nishimura as nothing short of an "angel," making her an irreplaceable figure in protecting their friendship.
