Madoka Kuki

As Chifuyu’s devoted classmate and most intimate friend, this caring individual takes on a nurturing role in her daily life. Often seen tidying Chifuyu's disheveled uniform or brushing her hair, she is dedicated to keeping her friend in perfect order. Whether walking her to school or providing constant support, her protective nature is unmistakable. Though she is known by her formal name, Chifuyu affectionately refers to her as "Cookie" during their close interactions.
