Portal Scene Generation Prompt

A detailed Japanese prompt for Nano Banana Pro that generates a scene where a character passes through a glowing oval portal, separating a 'real world' scene from an 'inner portal' scene. It strictly maintains the character's original style (illustration, anime, or photo) from the reference image while depicting the inner portal scene as photorealistic and cinematic. The character is shown looking back with a slightly sad expression. Via YouMind OpenLab prompt library (MIT).
