Micro science fiction + urban fantasy, well I really can't think of any other label.
When the earth was angered by war and the monstrous flood wiped out the world like a myth, the remaining humans had to flee into the universe. As one of the survivors, Rampu was tasked with finding a new home, but the destination was also called "Earth" among the indigenous people? Is this Rampu returning to his beloved hometown, or is there another Earth at the end of the universe? In the illusion of familiarity and unfamiliarity, Rampu unravels the cruel truth.
