This figure captures Yumia Liessfeldt in a sun-drenched swimsuit variant from the Yumia no Atelier universe. The sculpt emphasizes flowing hair swept to one side, with nuanced shading across a turquoise swimsuit and gold trim. The pose is dynamic: one knee bent, hand resting near hip, the other arm lifted gracefully as if caught mid-swim along a crystalline shoreline. The costume features a two-piece swimsuit with subtle alchemy motifs etched along the straps, a translucent shawl-like cover-up fluttering behind her. The base portrays a shimmering poolside scene with wave textures and etched runes. The paintwork blends soft gradients on skin, a glossy lacquer on the swimsuit, and metallic highlights on accessories. The overall presentation emphasizes elegance, strength, and a playful summer mood.

Within the story arc Yumia Liessfeldt is a prodigious alchemist who escaped a rigid academy to chase forgotten recipes and luminous crystals found near sunken ruins. In this swimsuit variant, she visits a coastal atelier where she tests new alchemical pigments under the sun, balancing danger and whimsy as rival collectors seek her craft. Her temperament blends curiosity, courage, and a touch of mischief; she negotiates with sea spirits and tinkerers to secure ingredients while protecting her friends. This figure hints at her resilience, her pursuit of beauty, and the idea that science and art can shine together, even in a summer pose.
