AI Prompt for Fantasy Anime Key Visual Poster in Film Style

"A cinematic fantasy anime poster in a tall vertical composition, showing two childlike adventurer characters standing in a vast magical library-cathedral with impossibly high gothic arches, towering bookshelves on both sides, floating pages, glowing dust, and a grand staircase rising in the center toward a radiant portal-like window filled with intricate celestial magic-circle patterns. The viewpoint is low and dramatic, looking slightly upward, with both characters reaching one hand toward the viewer in an inviting gesture. On the left is a slightly taller child with short silver-white hair, soft bangs, and large green leaf-like ear ornaments or animal-like ears, wearing a navy hooded jacket over a warm orange top, dark pants, sturdy boots, and a black crossbody satchel; keep the face partially obscured by framing or angle. On the right is a shorter child with a matching design language, short silver-white bob hair with green-tinted ends, large teal-green eyes, and the same green leaf-like ear features, wearing a navy hooded jacket, orange inner layer, short dark bottoms, boots, and a mauve-purple shoulder bag decorated with small charms including a star. Between their outstretched hands, create a bright burst of magical light where two energies meet: luminous cyan-blue streams curling around the left character and warm pink-gold streams curling around the right character, with spark particles and ribbon-like trails. Split the lighting mood into cool blue on the left side and warm golden-magenta on the right side, blending at the center into a brilliant white flare. Add dense atmospheric detail: glowing motes, magical filaments, floating sheets of paper, layered architecture, and a sense of wonder and discovery. At the top, include centered Japanese tagline text in elegant white serif style: "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, place a very large luminous gold serif title reading "{argument name="title text" default="Epix&Ria"}" with ornate cinematic poster typography. High-detail, polished key visual, fantasy adventure film poster, richly textured, radiant, emotional, awe-inspiring, premium illustrated promotional art."
