Character 'Participation Screen' Reveal Prompt

A highly structured, multi-layered prompt for Nano Banana Pro designed to create a dramatic 'Participation Screen' or reveal splash image for a character based on a reference image. It strictly preserves the character's identity and style while placing them in a 16:9 composition with a headline text ('参戦!!' - 'Participate!!') and a simple, atmospheric background.
