Dog Days is a 2011 Japanese fantasy anime television series created by Masaki Tsuzuki. The series revolves around Shinku Izumi, a cheerful and athletic half-Japanese, half-English boy studying at Kinokawa International School in Japan who is suddenly summoned to the alternate world of Flonyard. The people there look no different from humans, except for one thing; they have animal ears and tails. The one who summoned him is Millhiore, the dog-like Princess of the Biscotti Republic, who requested his assistance in their war against the forces of the feline-like Galette Lion Dominion. The wars in Flonyard differ from the ones on Earth, and are waged with special rules and no casualties in a fashion similar to a sports competition with the purpose to raise funds for the Kingdoms involved, where the winner faction claims a larger sum than the losing side.
After winning his first battle for Biscotti, Shinku learns that when a hero is summoned into Flonyard he becomes unable to return to his homeworld, a fact that Millhiore also was unaware of. The scientists of Biscotti promise to Shinku to find a way for him to return home in 16 days, the remaining time until his meeting with his friend Rebecca whom he promised to spend the last three days of his spring break with.
Dog Days is produced by Aniplex and Seven Arcs under the directorship of Keizo Kusakawa, with series composition by Masaki Tsuzuki, character designs by Osamu Sakata, music by I've Sound, Maiko Iuchi, Susumu Natsume and Yui Isshiki, and produced by the production company Project DD. The series aired 13 episodes from April 2 to June 25, 2011 on Tokyo MX, Tochigi TV, Gunma TV, Chiba TV, TVK, TV Saitama and MBS, with subsequent runs on CBC and BS11. Six DVD and Blu-ray Disc volumes were released by Aniplex between July 27 and December 21, 2011.[1]
