Description
Maryu is a deceased former member of the Astraea Familia, a group of adventurers who operated in Orario before the events of the fourth season of the series. Her full name is Maryu Reage, and she is depicted as a secondary character whose story is primarily told through flashbacks, particularly in the second half of the fourth season.

Maryu’s background begins with her childhood on Daedalus Street, where she lived as an orphan. Approximately ten years before the present timeline of the story, she joined the Astraea Familia, a familia dedicated to the goddess Astraea. Despite initial hardships, the familia quickly rose in prominence, and Maryu became a recognized adventurer who ranked up multiple times at a rapid pace. Her last level-up occurred seven years prior to her death, after she and her fellow familia members defeated the powerful adventurer Alfia during an event known as the Great Feud.

Personality-wise, Maryu is described as having a sisterly and fraternal attitude toward her comrades. She was deeply protective of her fellow familia members and harbored a strong hatred for Evilus, a criminal organization responsible for much suffering in Orario. Her motivation was fueled by a desire to retaliate against Evilus for the pain they caused, and she sought to harm them directly whenever possible.

Maryu’s role in the story is that of a fallen hero whose past is crucial to understanding the history of the Astraea Familia and the trauma carried by the elf adventurer Ryuu Lion. Maryu was a close comrade of Ryuu, along with other members such as Alise Lovell. Her death came two years after the Great Feud, when the Rudra Familia accidentally summoned a Juggernaut in the dungeon. The Juggernaut killed Maryu along with most of the Astraea Familia, an event that left Ryuu as the sole survivor and shaped her subsequent actions.

Key relationships include her bond with Ryuu, whom she treated as a younger sister, and her camaraderie with the rest of the Astraea Familia. She was also a teammate of Cecil Blackliza and other former members. Her relationship with the goddess Astraea is implied to be one of loyalty and dedication.

Maryu’s development is shown through the tragic arc of the Astraea Familia’s downfall. Her regret and desire for vengeance are revealed in flashbacks, illustrating how her death contributed to the lingering hatred and grief that Ryuu struggles with. The fourth season highlights the familia’s heroic final stand, cementing Maryu’s legacy as a martyr in the war against Evilus.

In terms of abilities, Maryu was a second-class adventurer, meaning her physical prowess far exceeded that of lower-level adventurers. Her raw power was dramatically superior to any Level 2 or below, and her senses were enhanced through the falna—a divine blessing that grows with each level-up. Her most notable skill was a wide-area healing magic called Rea Vindemia, which could heal wounds and restore stamina to multiple targets at once. This made her an invaluable support member of the Astraea Familia during battles. Despite her abilities, she was ultimately unable to survive the encounter with the Juggernaut.
