This Japanese animation tells us the journey of a young man named Rei. Rei is a young inventor living in the United Kingdom in the middle of the 19th century. This anime story starts shortly before the first ever World Expo, when a marvelous invention called the “Steam Ball”, behind which a menacing power is hidden, arrives at his door from his grandfather Roid. His grand father Roid was living in the United States. Meanwhile the nefarious Ohara Foundation has sent men to acquire the Steam Ball so that they can use its power towards their own illicit ends.
