Obaja Yozo's attempts to reconcile himself to na svete po jeho začiatkoch v rannej childhood, continue cez high school, kde he becomes a klaun to mask jeho alienation, a prípadne lead to a failed suicide attempt as an adult. Bez sentimentality, uviedol, že sú casual cruelties života a jeho fleeting momenty ľudského spojenia a tenderness.
