Description
B T Jutaim, also known as Je t aime or Jutaime, is a mechanical combat partner known as a B t, belonging to Fou Lafine within the Machine Empire. Her design is directly inspired by the Chinese mythological Vermilion Bird of the South, embodying the essence of a phoenix or hō-ō bird, which dictates her visual identity and core attributes. Her name originates from the French phrase je t aime, which translates to I love you, reflecting the themes of devotion and rebirth central to her character.

In terms of personality, Jutaim is presented as a loyal and dedicated entity whose narrative purpose is intrinsically linked to her partner, Fou. While possessing significant independent combat capabilities, her motivations are centered on supporting Fou and engaging his enemies. She is not depicted as a character with extensive dialogue or emotional range separate from her role as a B t, but her actions demonstrate a fierce protectiveness and a willingness to engage adversaries like members of Crow in solo combat.

Her role in the story is primarily defined by her partnership with Fou Lafine and her conflicts with the antagonist Quattro. A pivotal moment in her narrative occurs when she suffers fatal damage at the hands of Quattro. Following her destruction, Fou resurrects her by playing the song of the angels on his violin. This act unlocks her latent revival ability, transforming her into a true phoenix form. In this ascended state, her appearance shifts from its original vermilion hue to emit a distinct pinkish glow, symbolizing heightened power and purity. This event reinforces her central theme of renewal and her dependence on Fou for her ultimate transformation. The storyline does not explore significant functional changes or evolution beyond this resurrection and her amplified combat role.

The key relationship in Jutaim s existence is with Fou Lafine. Their bond is both emotional and tactical, as his music directly amplifies her abilities and is the catalyst for her rebirth. Her resurrection ability remains passive, requiring the external activation of Fou s violin performance to trigger her rebirth into the true phoenix state. This dependency creates a powerful symbiosis where her survival and transformation are directly tied to his actions.

Regarding her development, the most significant change is the physical and power-based evolution into her true phoenix form. Prior to this, she is a formidable combatant, but her transformation represents a marked increase in her capabilities. However, her core function and loyalty remain unchanged, with the narrative focusing more on the event of her resurrection than on a gradual character arc.

Jutaim possesses several notable abilities that make her a dangerous opponent. Her primary offensive technique is Deadly Carol, a sonic wave attack designed to disrupt or destroy a target B t s control system or electronic brain. This attack induces powerful hallucinations of angels and skeletons, leading to the target s mental collapse. The effects can be negated by disabling auditory sensors, and the technique poses no risk to human beings. When synchronized with Fou s violin performance, this ability is amplified into Fortune Symphonic, which forges psychological and emotional bonds with anyone within range. In the OVA sequel, her body itself acts like an instrument, and resonating with Fou allows them to perform a technique known as the Forgotten Lullaby (Lost Lullaby). Her signature ability remains her resurrection, which, though passive, allows her to regenerate like a phoenix when she hears Fou play the angel s poem, a power she herself was initially unaware of possessing.
