Celestiana Megistos is portrayed as a poised, collectible figure in 1/12 scale, wearing the swimsuit variant from Soushin no Ars Magna. The design emphasizes clean, high-contrast sculpting with a focus on expressing her calm confidence and regal bearing. The head sculpt captures her features with subtle expression, while the hair is arranged to frame the face and flow naturally over the shoulders. The swimsuit is reproduced with attention to fabric texture and tailored seams, providing a sense of movement when viewed from multiple angles. Skin tones are matte with a gentle highlight, and the overall finish balances realism with the bold lines typical of collectible figures. The piece is built for stable posing on a display shelf.

In the world of Soushin no Ars Magna, Celestiana Megistos is a prodigious tactician and adept user of the Arcane Ars Magna. Born into a family of scholars, she travels between city-states to prevent rival factions from triggering a larger conflict that would threaten the balance of power. Her calm demeanor and sharp intellect allow her to decipher ancient inscriptions, exploit strategic advantages, and shield allies during perilous campaigns. The swimsuit variant hints at a rare moment of leisure between missions, a festival by the sea where she can breathe and reflect. Yet rumor and intrigue persist, and Celestiana remains a focus for those who seek to weaponize knowledge against her world.
