Since thousands of years ago, all of the worlds have lived side by side in peace, undisturbed. Until the Gods made a mistake, the Nine Gods thought the living beings on the surface were mere a show, but...
That mistake was the beginning of a total destruction. A single power that was made to entertain the Gods fell into a world where magic did not exist.
That power seeks the most suitable owner, and when it finds the owner, all the worlds are connected by that single power.
For centuries, a family from Earth used the power to collect wealth, take resources from other worlds, and provide that family with the most glamorous life that could be imagined. Passed down for generations, that power makes the family escalate, higher and higher.
One day, all the living things in the world where magic exists, found that power existed, greed controlled them to get that power the heir possessed, but the heir wasn't a weak man, he unleashed the true power in his hand, challenged everyone, every kingdom, every races...
But the Nine Gods, decided to step in, after generations of the power had passed down, a final war, an unimaginable destruction, happened, and ended with...
A loving man of Earth got killed in front of his wife.
A caring, cursed witch got killed in front of her husband.
By all the living things, and with the Gods alongside them.
Leaving a boy on earth, became an orphan, not knowing what awaits him.
