In the year 2011, scientists with the help of the other-dimensional people found out that a third dimension is going to merge with the main dimension in less than 2 years. They together built a machine that helped people to travel through dimensions so that they can go to that dimension and bring some information of that dimension so that they can prepare early for the dangers that the dimensions bring after merging. Later they found that this machine can only allow people with special souls with high soul power to travel through dimensions. Later with the help of the mana satellite, a total of 128 children with the age of 6-10 were born with special soul required for dimensional traveling machine and called them the chosen.
