OVA
Description
Chiaia Furan serves as the personal bodyguard and escort for Lashara Earth XXVIII, sworn to protect her life unconditionally. She attends Holy Land Academy, where her sister Mexiah teaches, to finish Seikishi training and formally becomes a Seikishi by episode's end. Her combat prowess shines through her ability to replicate Kenshi Masaki's unorthodox Seikijin fighting style after a single observation. Her pink-and-red Seikijin features a fox-like tail and wields a longsword.

Initially blinded by a long-standing crush on childhood friend Dagmyer, she overlooks hints of his plot to seize the Holy Land until too late. She vents frustration at Kenshi's obliviousness and Lashara's risky schemes, with Lashara treading carefully around Chiaia's temper. Despite reservations, Chiaia joins Lashara's plan to hide Kenshi's identity as Lashara's would-be assassin.

Subtle attraction to Kenshi surfaces early—blushing at his compliments, jealousy over his bond with Wahanly Shume—and peaks when she unknowingly repairs his pendant with a love-signifying red thread, leaving her mortified. Yet these feelings remain buried under her Dagmyer infatuation and general irritation with Kenshi. After Dagmyer commands her to kill Kenshi following the Holy Land assault, she cannot comply, confessing to Lashara that Kenshi apologizes in his sleep. Confronting Dagmyer, she abandons her romantic feelings upon seeing his true nature.

Later, spotting the red thread on Kenshi's pendant during an assassination-attempt discussion, she recalls its meaning and acknowledges her feelings. Her demeanor toward Kenshi softens into friendliness, protectiveness, and concern, almost sibling-like, though she still scolds him—particularly for crystal-digging that risks damaging the Swan, dubbing him "Boss of the Koros."

Chiaia's mother piloted a Seikijin against Lashara's mother’s faction; they are distant, implying Chiaia was raised by her father alongside adopted sister Mexiah. With red hair and green eyes, she blends combat mastery, a fiery temper, romantic fluster, and latent kindness. Her growth yields a steadier outlook: unwavering loyalty to Lashara, yet expanded trust and affection forged through Kenshi's influence and Dagmyer's betrayal.
