The Hard Part
It seemed that there had once been a Human Domain in this Dimensional Verse, or rather the Sea God Verse as they called it, but it had been invaded and, unlike in Leonel's world, they hadn't managed to withstand the blow.
Unsurprisingly, many of the great powers had retreated to their territories in hopes of protecting their foundations instead of going all out to meet the enemy together.
This happened in Leonel's world as well. The difference was that this Sea God Verse didn't have a Leonel Morales or his father to pick up the slack. So, the stupidity of the humans ended with their powers being wiped out systematically, one after another, until now there was just one bastion of the Human Race left.
In truth, Leonel and Aina's appearance wasn't all that surprising because many humans had fled their Domain.
