Mana visits Sakaiminato where her aunt and uncle live. In order to cheer Mana up after she learns that the festival has been canceled, her uncle Shouji goes out fishing to catch her a lively fish, but he never comes back. Mana goes out on a boat with fisherman from town to search for him, and gets attacked by marine spirits on the open water. The ghost ships turn out to be Shouji and the other missing fishermen. When the boats are sunk, Mana is the only one to reach shore. Kitaro, who came to help, heads out to sea where mist from the boats rises. There, he and the marine spirits face a yokai that was supposed to have been sealed away, Umizatou.
If you fear change,
you'll drive people away!
!سينفر الناس إن خشيتم التغيير
¡El miedo al cambio aleja a la gente!
¡El miedo al cambio aleja a la gente!
À craindre le changement,
vous ferez fuir les gens !
Se avete paura dei cambiamenti,
 la gente si terrà lontana!
Se tiverem medo de mudança,
afastarão as pessoas!
Люди отсюда уезжают, 
потому что вы что-то менять боитесь!
