Shiori

Shiori makes her debut in the third season as the daughter of the neighborhood's resident police officer. A chance encounter with Renge—sparked by Shiori getting lost—blossoms into a genuine friendship, as the two girls quickly bond over their shared sensibilities and mutual interests. She affectionately calls Renge her 'big sister,' and her wide-eyed wonder at the world around her makes her an endearing presence. By the story's conclusion, she officially joins Asahigaoka Branch School, becoming the very first kouhai in Renge's life.
