Chibi Mobile RPG Event Campaign Poster

An event campaign promotional illustration for a Japanese mobile fantasy RPG. Adorable chibi anime characters—deformed heroes and cute mascots—are opening a treasure chest with joyful smiles. Brilliant golden light and sparkling magical particles burst from the chest. The background shows a vibrant lush fantasy island with green forests, floating islands, clear blue sky, and fluffy white clouds. At the top or center, decorative fantasy typography displays the game title "[Treasure Hunt!]", with subtext "[Find treasures on a great adventure island!]" and "[RPG Adventure Action!]". Bright high-saturation fantasy color palette, magical gloss, clean digital cel-shading, soft ambient lighting. Direct full-canvas flat 2D graphic illustration, edge-to-edge, no frame mockup, no photographic perspective, no wall shadows.
