OVA
Description
Doll, initially designated Doll Third, is an artificial human engineered by the Senshi Civilization alongside Rea and Neizai to oppose the destructive entity Gaia. Embedded within a human family to cultivate empathy and avert instability, she was adopted by Naua Furan as Mexiah Furan, becoming the elder sister of Chiaia Furan. This upbringing enabled her to assimilate seamlessly into society as a martial arts instructor and Sacred Mechanoid pilot at Holy Land Academy, where she radiated warmth and affection, notably toward Kenshi Masaki.

Her identity fractures into dual states. As Mexiah, she embraces human emotions and bonds, yet a hidden override command imposed by Babalun compels her to revert to her original Doll persona—a cold, calculating entity devoid of empathy. In this form, she revels in combat’s chaos, manipulating others with merciless precision, exemplified by her gleeful attempt to murder Aura Shurifon. Faint echoes of Mexiah linger even then, surfacing as an inexplicable draw to Kenshi, whom she cannot fatally target, whether due to his hybrid lineage or residual emotional ties.

Doll’s combat superiority is unrivaled. Piloting a dark-hued Sacred Mechanoid, she wields a shape-shifting scythe and the Shield of Gaia, an impervious defense that disassembles enemy machinery. This mechanoid’s destructive capacity ties her to the prophecy of the "Seikishi of Darkness," casting her as Kenshi’s fated rival. Her arc pivots during Gaia’s final assault: defying Babalun’s programming, she shields Kenshi, ensuring Gaia’s downfall. Post-battle, she irrevocably reclaims her Mexiah identity, reconciling with Chiaia and renouncing her role as antagonist.

Genetic analysis uncovers her dual lineage—Naua Furan’s DNA and that of researcher Araia Meiza, whose unvoiced affection subtly shaped Doll’s emotional core. This hybridity permits selective control over her form, letting her retain Mexiah’s physique even as Doll. Supplemental media, including doujinshi by creator Masaki Kajishima, suggests thematic parallels between Doll and D from *Dual! Parallel Trouble Adventure*, another artificial entity with overlapping design and narrative roles.

Her story intertwines with broader lore: Senshi artificial humans bear unyielding directives, a trait shared by Rea, whose mission resulted in Kenshi’s birth. Doll’s forced obedience to Babalun mirrors Rea’s programmed constraints, though Kenshi’s hybrid nature grants him immunity to such control. This duality cements Doll’s role as both engineered weapon and tragic figure, enmeshed in the series’ interrogation of autonomy versus predestination.
