I'm Metia

A young man with dark hair holds a golden mirror, initially showing his own face, then revealing a pink, round creature with large eyes and a mustache inside the mirror's reflection. The scene cuts to a confrontation with a green-skinned, monstrous figure in a dark robe, who points an accusing finger, while the mirror's reflection shows the creature now wearing a black mustache. The setting is an outdoor area with green foliage and stone ruins.
