Anzu Takanashi, younger sister to the popular Mitsuya, becomes entangled in a web of deception after obeying her brother’s directive to seek help upon getting lost—an act that spirals into falsely branding Hikari Tsutsui as a lolicon. The misunderstanding stems from her panicked compliance, but Anzu later confronts the consequences by confessing the truth to Iroha Igarashi, dismantling the rumors and restoring Hikari’s reputation.

Her path intertwines with Kaoru Tsutsui, Hikari’s younger brother, sparking a romance that evolves after she uncovers their sibling connection. This bond draws her back to the high school, where she engages with Hikari and peers to mend lingering tensions from her earlier actions. Anzu’s journey reflects a transformative arc: from complicity in her brother’s manipulations to proactive accountability, driven by remorse and a resolve to amend past harms.

Her name, Anzu (杏), evokes the apricot tree, while Takanashi (高梨) blends “tall” and “pear.” Visually distinct with light orange hair and cyan eyes, her characterization centers on her pivotal role in the conflict, with narrative focus on her actions and growth rather than extraneous backstory.
