Mahiru Kasumi

Possessing a natural talent for modeling that rivals her older sister, Yozora, this mature young woman harbors deep-seated resentment toward her sibling. Her commanding presence and intense aura often make her appear intimidating or unapproachable to fellow students. However, her cold exterior begins to melt following a small act of kindness from Koharu, whose simple gesture of offering cough drops allows for a surprising and rapid friendship to blossom.
