Aries Spring sports light skin and vibrant pink hair, its ends playfully curled, her striking heterochromia casting a green left eye and golden right. Clad in a sleek white-and-pink Hyperion spacesuit with coordinating hair accessories, she radiates cheerfulness, her optimism occasionally punctuated by spatial forgetfulness or tangled words—yet flashes of ingenuity emerge, like repurposing the Ark VI’s components for critical repairs.

A genetic replica of Vixia’s Princess Seira, she was sheltered from royal intrigue by adoptive mother Emma Spring, growing up in rural simplicity before enrolling at Caird High a month prior to the Planet Camp expedition. Throughout the voyage, she bridged connections even with aloof companions like Quitterie Raffaelli, her earnest warmth dissolving barriers.

Her photographic memory proved indispensable: navigating Vilavurs’ terrain, pinpointing the traitor via McPa’s wormhole absorption sequence, and unraveling Charce Lacroix’s fabricated class history. Though initially dismissing her feelings, Aries grew enamored with Kanata Hoshijima after his wormhole rescue, their bond evolving into mutual devotion. Charce, recognizing her cloned lineage, abandoned his mission to eliminate the group, shielding her instead.

Grounded by resilience and gratitude, Aries openly thanked allies who aided her, her resolve to cultivate authentic ties rooted in her origin as a royal organ donor clone—a fate Emma defied. Post-journey, she sustained lifelong friendships, attending Yun-Hua Lu’s concerts and cherishing camaraderie years beyond the stars.
