The opening theme is "Jingo Jungle" by Myth & Roid and the ending theme is "Los! Los! Los!" by Aoi Yuki as Tanya Degurechaff. To have offended God with his immoral conduct and his lack of faith, an ambitious and cynical salaryman Japanese, after his sudden death at the hands of an employee who had been fired, it is made to reincarnate in an alternate world, similar to Europe the Great war, where the German empire is engaged in a never-ending war with all its neighbors, with the promise from God that if it were to die yet after death violent or be unable to express sincere faith in him, his soul will be devoted to hell.
