Young Master Ken'nosuke

Kennosuke is a 5–6 years-old samurai very well mannered and very serious. He has a date with a girl named Miss Oden. Not knowing the good practice in a date, Kennosuke seeks advice from his mother and his best friend Shinobimaru, with discretion, so that no one realizes it is his first time. After a visit to the seaside and time passed in a small cafe, Kennosuke gets the opportunity to demonstrate his ability in combat when a gang tries to steal his money.
