The album is dedicated to Minazo, who was the only male southern elephant seal in Japan. Minazo was brought from Uruguay in 1995, and was kept at Enoshima Aquarium until his death on October 4, 2005. He was 11 years old; the average life expectancy of an elephant seal is 20 years. In the liner notes, Masami Akita writes that Minazo was made to perform tricks at mealtime, which Akita speculates left him exhausted and may have led to his early death. Akita also laments that many of the aquariums in Japan are mere amusement establishments, and hopes that they will eventually end the exhibition of animals and only function as shelters for those that are endangered.
Minazo was previously depicted on the cover of Merzbeat.
