Reine Murasame is the brilliant and mysteriously sleep-deprived Head Analyst aboard Fraxinus, and the dependable assistant homeroom teacher at Raizen High School. Known for her calm, motherly demeanor and logical mind, Reine serves as Shido Itsuka’s indispensable guide and support in his missions to seal Spirits.

However, beneath her composed exterior lies the secret of her true identity: the elusive Spirit Phantom, whose manipulations have altered the lives of many, transforming humans into powerful Spirits. Reine’s ultimate goals remain as murky as the mosaic that shrouds her Phantom form, but one thing is clear: her past and her deep ties to Mio Takamiya harbor a wish that has influenced the very fate of the world.

Personality & Appearance

Credits: Studio AIC Plus+

Reine Murasame is a paradoxical figure—a blend of warmth and cold detachment. She is compassionate, offering sage advice to Shido and calming even the most chaotic Spirits, often acting as a maternal figure to the group. Yet, her emotional core appears scarred, haunted by an unrelenting insomnia linked to nightmares of tragic loss, which she claims has prevented her from sleeping for 30 years. Her calm is nearly unshakeable, but when angered, her fury is bone-chilling, a rarity that Kotori Itsuka only witnessed once.

Reine’s appearance captures her exhaustion yet maintains an ethereal beauty. With long, pale blue hair tied into a messy side ponytail, dark circles shadowing her intelligent blue eyes, and round glasses perched on her nose, she seems perpetually weary. Her slender frame is usually clad in Ratatoskr's uniform or her white lab coat over a V-neck top and miniskirt, complete with blue teddy bear slippers—a quirky touch to her otherwise professional attire. A small blue teddy bear is a constant companion, fitting snugly in her breast pocket.

As Phantom, Reine’s form is obscured by a mosaic effect, distorting both her voice and appearance. When needed, she can assume other shapes, such as Rinne Sonogami. Her full power manifests through an Astral Dress reminiscent of Mio Takamiya’s, adorned with translucent water-like fabric, golden jewelry, and floral designs.

Powers & Abilities

Reine, as Phantom, possesses a range of abilities tied to illusion, manipulation, and deduction. Her powers, though rarely showcased in full, are formidable.

• Phantom Disguise: Reine surrounds herself with a shimmering, noise-like mosaic that alters her appearance and voice. This defense mechanism can withstand powerful assaults, such as Kurumi's bullets and Metatron’s beams.
• Memory Manipulation: Phantom can alter or erase memories, a skill she has used to keep Spirits’ transformations secret or to influence key events.
• Shape-Shifting: She can take on the appearance of others, such as Rinne Sonogami, to manipulate or deceive.
• Deductive Genius: Reine is a master strategist, able to deduce complex scenarios, such as time travel events, and predict her opponents' moves with chilling accuracy.
• Spirit Form: When cornered, Reine can summon her Astral Dress and wield tremendous spiritual power, though full access to her abilities requires merging with Mio Takamiya.

Reine’s influence stretches deep into the heart of the series’ conflict, manipulating events to further a mysterious wish. Her abilities and intellect make her a formidable force, one both feared and respected.
