Canon Hazama, born Canon Memphis, emerges as a battle-hardened Fafner pilot within the Neo United Nations' Human Army, her identity forged by the destruction of Dublin, Ireland, and the loss of her family four years before the central story. Adopted by soldier Hino Michio, she evolves into a disciplined warrior stripped of personal autonomy, her existence tethered to survival in an unending war.

Her transfer to Tatsumiya Island disrupts her worldview. Confronted by the community’s tranquility, she initially reacts with distrust but gradually bonds with residents like Sakura Kaname and Yōko Hazama, whose guardianship inspires Canon to adopt the Hazama surname—a testament to their deepening kinship. These connections reawaken dormant hope, paralleling humanity’s fragile pursuit of peace amid decades of strife.

As a pilot, she transitions through multiple Fafner units: beginning with the Babalon model, briefly commanding the Mark Drei, and ultimately spearheading operations in the Mark Dreizehn. During the *Heaven and Earth* conflict, she shields the island from Festum assaults, mentoring novice pilots through encouragement over censure—a shift underscoring her maturation into a leader.

The *Exodus* arc amplifies her burdens. Sustained interaction with Tatsumiya’s core grants her fragmented precognitive visions, a power eroding her vitality. In her final days, she channels fading strength into engineering the Einherjar-model Fafner and countermeasures against pilot assimilation, solidifying her strategic legacy against the Festum.

Unspoken feelings for Kazuki Makabe linger beneath her stoicism, while bonds with Sakura and Yōko trace her journey from isolated soldier to integral community member. Her arc culminates in a sacrificial gambit: leveraging her disintegrating visions to rewrite the war’s trajectory, her body dissolving into light. This act bridges devastation and renewal, echoing her dual role as both warrior and harbinger of reconciliation.
