Early Reins features six beautiful women on a train en route to Sunshine Hill in the early 1800s. When the train is highjacked by robbers and the soldiers on board are caught unawares, another surprise is in store: these lovely ladies can fight! The heroine emerges as Margarette, a young woman determined to become a sheriff although she is somewhat lacking in experience. She gains plenty on this trip, however, and the ragtag team of Western warriors joins forces with another passenger, Spencer, to fight some nefarious bandits and guide the train to safety.

The age of the demons has begun. Dr Faust has foreseen this rise of evil. Unfortunately, he is near death and is unable to personally battle this upcoming threat. Faust entrusts a young boy, Shingo Yamada, to take the responsibility of ridding the Earth of this new evil presence. Faust finds a birthmark on Shingo's forehead that signifies that he is the chosen demon fighter. Faust summons from hell what may be humanity's only hope of surviving: a less than enthusiastic devil named Mephisto rises. After signing a pact in blood to save humankind, Shingo and Mephisto set out to battle the supernatural world. (Source: AniDB)
