Dog Days

inque Izumi is a cheerful and athletic half-Japanese, half-English boy who studies at Kinokawa International School in Japan, and has a normal life everyday until he suddenly got summoned to the alternate world of Flonyard (フロニャルド Furonyarudo?). 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 (ビスコッティ共和国?), who requested his assistance in their war against the forces of the feline-like Galette Lion Army (ガレット獅子団領 Garetto Shishi Gundan?).
After responding to Millhiore’s plea, he receives a sacred weapon, the Palladion (パラディオン Paradion?), and is appointed as a Hero to fight for Biscotti in a war that unlike the ones in Earth, is 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, Cinque 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.
