ensemble poster design — Collage / Montage · Oversized Title · Bottom Title

A vibrant anime ensemble of a dozen fantasy characters against a night castle: a blue-haired slime-humanoid youth in black holding a staff at the center, red-haired horned warriors, a purple-haired demon girl, a pink-haired girl, a dark-suited demon butler, a green-haired queen praying above before a moonlit fortress; magical water effects swirling. Top right vertical white-and-gold tagline; bottom center the quoted text "TITLE" in large blue and dark-blue rounded anime characters with a red subtitle beneath. Glowing magical lighting, electric blue, red, and gold palette, isekai anime style, epic adventure mood.
