Gloria, also known as Gloria the Wrathful, is a formidable opponent encountered deep within a dungeon by the protagonist Ornest. Her background is shrouded in mystery, as she is considered one of the most enigmatic members of an ancient organization, with many aspects of her past remaining unknown even to her peers. Despite medical examinations classifying her race as human, her immense knowledge and capabilities are highly unusual, with records of individuals matching her description appearing throughout the histories of various civilizations.

Gloria's personality is defined by a deep appreciation for knowledge and human wisdom, paired with a strong aversion to unreasonable situations and illogical people. She is a master strategist, frequently devising plans for her organization in both missions and日常 meetings, demonstrating that her power is matched by her cunning intellect. This serious and calculating demeanor is balanced by her distinctive combat preference; although a master alchemist, she favors creating various types of swords and combining them with martial arts techniques amplified by her unique power, simply because she has a personal fondness for cold weapons.

Her primary motivation appears to be a private, undisclosed personal goal that drives her to leave her organization's base frequently to travel across different dimensions. One of her few known joys is to serve as a "blind sage," wandering through worlds to传授 countless technologies and knowledge to humanity, thereby fostering the development and evolution of civilizations. She takes supreme delight in cultivating talented or strong-willed individuals, a pursuit that has earned her the title of "Blind Sage" among the people she has aided.

Within the story, Gloria serves as a powerful adversary and a source of significant tension. Her confrontation with Ornest is a character-driven clash that highlights his practical combat instincts against her unsettling blood-based abilities. This battle is not merely physical but also provides insight into the characters' motivations, setting the stage for larger, more troubling developments beyond the immediate fight. Off the battlefield, she holds several important relationships within her organization. She is the personal teacher to a character named Ashet, instructing her in both basic combat techniques and cultural knowledge. Gloria is also the only person who can easily communicate with the mute member Dies, and she often engages in swordplay and academic discussions with him. Furthermore, as the organization's second-in-command, she regularly debates various topics and organizational matters with its leader, Aranaga.

Gloria possesses a unique power tied to her Truth, or inner understanding, which is called "Glory," representing the symbol of honor and a future of victory. This Truth allows her to know all of human wisdom and perform high-level alchemy. However, this power came at a terrible price: the loss of her eyesight. In combat, she can unleash even more fearsome transformations. Her most powerful form is activated by releasing the "Chimera Blood" within her, which transforms her from human into the "Inscrutable Beast". In this state, her white Glory becomes a "black Glory," but her human reason is gradually consumed by brutal兽性, and the transformation causes irreversible damage to her body the longer it is maintained. Another special form is the "Sediment Water Sword," where she manifests her soul as a massive flaming sword. This form boasts power that even other powerful figures find threatening and has the ability to burn any civilization to ash, but it seals her "Glory" power, drains her energy immensely, and risks her own destruction if used for too long.
