Faria presides as student council president at Granseed Academy and leads the new generation of Seven Knights, warriors who inherit powers from legendary heroes via the Succession bonding process. Her soul is bonded to her ancestor Yunomia, an original Seven Knight, granting her formidable combat abilities; she wields a double-bladed axe spear as her primary weapon.

Her story opens with her rescuing a boy named Nemo from monsters connected to the destructive cult Physis. Recognizing his potential, she secures his enrollment at Granseed Academy for warrior training. Initially serious and duty-bound in their interactions, Faria gradually reveals a warmer, protective side, particularly towards Nemo. This protectiveness intensifies dramatically when false evidence leads to Nemo's attempted execution; Faria risks her life to intervene, resulting in her infection by a destructive power sealed within the academy's old library. She consciously accepts this curse to prioritize Nemo's safety above her own well-being.

As the conflict with Physis reaches its peak, Faria confronts the cult's true leader, Sophitia. During the final battle, she witnesses Nemo sacrifice his powers to recreate the Book of Time, an act that seals Sophitia and the dark forces but permanently severs his connection to the heroic legacy. With the immediate threat neutralized and her curse lifted, Faria resigns from Granseed Academy. She chooses instead to accompany Nemo on a journey beyond the academy, dedicated to discovering a way to permanently destroy the Book of Time and prevent its future misuse.
