Meg is a seasoned magical warrior combating parasitic Yuragi demons that possess humans, feed on negative emotions, and threaten humanity. She fights alongside allies Ai and Rin. Once enslaved by the powerful Mega-Yuragi Shin, she implanted a fragment of her heart within human Akitoshi Okajima. This safeguard ensures she can reclaim her free will if ever controlled by Yuragi again, as the external fragment remains beyond their reach.

Serving as vital support for her trio, Meg creates portals enabling travel between the human world and her native magical realm. This power secures essential supplies and reinforcements. Kind and helpful, her comrades respectfully call her "Onee-san." Despite this nurturing demeanor, her extensive combat experience fuels strong confidence in her abilities. She believes she can face both Shin and his mutant daughter Mayu simultaneously.

In battle, Meg maintains composure and strategic foresight, consistently planning several steps ahead to adapt to threats. Her primary combat ability is "Hyperregeneration," instantly and fully restoring a wounded ally's fighting capabilities. While significant, this power is insufficient to match Shin's raw strength. Her past includes severe trauma: capture and intense tentacle torture alongside comrades, inflicted by Shin in his campaign to destroy humanity.
