ARMS – mysterious, ultra-rare weapons of almost unbelievable power. So how did Sheyenne Rainstorm come into possession of one? More importantly, how did the twenty-five year old gunslinger end up in the body of a five year old boy? These are questions Dr. Kiel Aronnax would like to see answered. Sheyenne just wants to find his original body. On the other hand, fortune hunters Loretta Oratorio and Crimson Noble Mirabelle are only interested in treasure. So why, with the whole wide, wild west to travel, do they keep bumping into each other? They’ll dodge gunfighters, con-artists, dragons and crazed librarians in search of clues to solve the riddle of the ARMS.
