That enemy of flies…

A purple-skinned character with a gold headband and a red scarf stands close to a man in a black hat, their faces nearly touching in a tense confrontation inside a traditional Japanese building. The scene cuts to a man with a white headband and gold beads shouting angrily, then to a man in a red robe running across a balcony, followed by a shot of him standing in a library, and finally to him peeking through a doorway with a book, his expression shifting from surprise to shock.
