Pyra

Pyra (Japanese: ホムラ, Homura; English dub: /ˈpaɪ(ə)rə/) is one of the female protagonists in Xenoblade Chronicles 2. She is the Aegis, a Legendary Blade who can grant tremendous fire-elemental power to her Driver, Rex. Pyra and Rex embark on a journey to search for Elysium, and Rex is devoted to protecting her. Due to sharing her life force with Rex, Pyra is not able to recover from injuries like other Blades, and is as vulnerable to damage as any other human. If either of the two were to die, the other would follow.
