The household falls into constant arguments, and its calm everyday life seems gone. Black Jack crosses paths with the family by chance and uncovers the reason behind her apparent greed, a secret rooted in her love for her son. The short film was made for a theater at Tezuka Osamu World in Kyoto, where the Phoenix introduces it and then tells of the capital's move to Heian.
