Affiche Anime Fantastique de Bibliothèque Magique

A cinematic fantasy anime poster in a tall vertical composition. In a vast magical library-cathedral with towering gothic arches, floor-to-ceiling bookshelves, floating paper sheets, and glowing dust, a grand central staircase ascends toward a radiant portal-like circular stained window inscribed with intricate celestial magic circles. From a dramatic low angle looking slightly upward, two childlike adventurer characters stand side by side, each extending one hand forward toward the viewer. On the left stands a slightly taller child with short silver-white hair, soft bangs, and large green leaf-like ear ornaments, wearing a navy hooded jacket over a warm orange inner shirt, dark pants, sturdy boots, and a black crossbody satchel, face partially shadowed by angle. On the right stands a shorter child with a silver-white bob haircut tipped with soft green, large luminous teal eyes, and matching leaf-like ears, dressed in a navy hooded jacket over an orange top, short dark bottoms, boots, and a mauve-purple satchel with small charms including a star. Between their outstretched hands, a brilliant burst of magical energy collides: swirling cyan-blue streams on the left meet warm pink-gold ribbons on the right, erupting into a radiant white flare with sparkling particles. The ambient lighting splits cleanly with cool mystical blue on the left and warm golden-magenta on the right. At the top, centered Japanese tagline in refined white serif font: "わかることと、感じること。2つの力で世界をひらく。" At the bottom, a prominent cinematic title in glowing ornate gold serif typography reads: "[Epix&Ria]". Polished anime key visual illustration with rich atmospheric depth.
