Baseado na história do mestre de mangá Leiji Matsumoto (O Cockpit, Rainha Emeraldas), a curta-metragem de 55 minutos continua um ano após os eventos do Expresso da Galáxia 999, no qual um garoto chamado Tetsuro e seu companheiro Matel trabalham em conjunto para livrar o universo do Império Mecanizado que havia dominado a Terra.
Kitaro is a yōkai boy born in a cemetery and, aside from his mostly decayed father, the last living member of the Ghost Tribe (幽霊族 yūrei zoku?). He is missing his left eye, but his hair usually covers the empty socket. He fights for peace between humans and yōkai, which generally involves protecting the former from the wiles of the latter.
After a storm hits their island, Yusuke (driving his jet-ski) finds a baby dinosaur. He show it to his dad, they keep it and call it Coo. But there are other parties interested in a 65 million year old creature...
