Mahoro, a classmate of Arajin Tomoshibi and sister of Marito Jin, navigates complex relational dynamics with unyielding self-assurance. Though positioned as a potential love interest for Arajin, she rebuffs his advances with palpable disdain, dubbing him “rock guy” and maintaining deliberate emotional detachment. Arajin’s persistent romantic pursuit clashes starkly with her indifference, underscoring his obliviousness to her contempt. Her bond with Marito anchors her narrative significance. She admires her brother intensely, yet her devotion remains non-romantic and unreciprocated. Defying any expectation to conform to Marito’s tastes, she clings fiercely to her personal style and identity, framing her resolve to prioritize self-autonomy over external approval. A defining moment arises when Mahoro confronts Akutaro Shindo of the NG Boys. Despite her physical vulnerability, she challenges his hollow persona and lack of authentic self, refusing retreat or compromise. This act cements her as a symbol of resolute individuality within the story, contrasting characters mired in internal conflict or societal pressures. In the epilogue, Arajin mimics Marito’s appearance in a final bid for her affection, implying her admiration for her brother influences others’ assumptions about her desires. Her reaction remains undisclosed, preserving ambiguity around her romantic trajectory. Throughout, Mahoro’s consistency in valuing self-identity above validation aligns with the series’ emphasis on integrity and earnest self-expression.
