When Hikaru confronts Chiaki Enno with hostility, Michiru intervenes, striving to de-escalate tensions through gentle diplomacy. Her actions stem from a deep-seated devotion to her sister’s safety, clashing painfully with Hikaru’s willingness to die as a sacrifice to the Anki Kitan. Michiru openly resists this self-destructive path, pleading for mutual survival over martyrdom.

Bound by unwavering loyalty, the sisters ultimately reject their family’s ritual by facing the Anki Kitan together, their intertwined fate sealing the tradition’s demands through shared death. Though their mother opposes the practice and seeks outside intervention, Michiru’s allegiance to Hikaru overrides external salvation, anchoring her choices to protect their bond at all costs. Her story weaves quiet resilience with emotional fragility, illustrating a struggle to reconcile love with the oppressive legacy dictating their lives.
