All his life, Scarlet has always lived in Hell like any demon, with no particular purpose or role in the demonic hierarchy. Scarlet has always wondered how the outside world is like, the Earth and all its creatures. However, his wish to leave the confines of Hell might come true when he is sent to Earth in search of a missing demon commander, but soon finds that earth may be as dangerous, or even more, than Hell. Talking cats, dark magic-wielding dragons, a group of unfriendly demons, a mysterious creature form the sewers, a bad-tempered teen girl taken as a hostage and an organization of demon-hunting warriors can make his first visit to earth a complete disaster, especially since a dark secret kept from him might come to light, revealing there is much more to him than he thinks. It's going to be a long week.
