Rakuin no Monshou - Volume 9, Afterword

Do you know how this world ends?

As the final dragon lay defeated, Aaran stared at the sky while the rest celebrated.[Awaiting the gods’ response...]He clenched his fists, his heart pounding. A shred of hope flickered in his eyes, only to be extinguished like always.[The attained outcome was deemed unsatisfactory.]Aaran had seen the message for the twentieth time. He had become the gods’ plaything in their desire to witness the “perfect ending”.He regressed once again, but this time as a toddler and charm being the only stat he had.But something was amiss. The world he remembered had changed. Powers that did not exist before had taken hold of the world.Tired of following the traditional route, Aaran chose to fight darkness with darkness… as the gods’ chosen necromancer!

Nero was an orphan boy who one day went to sleep like any other day in his apartment. However, what he did not know that the moment he slept, it would be his last day of life...Or at least that was how it should be.Nero's soul wandered between the worlds and ended up entering the body of a girl who was trapped in a human mutation laboratory. While the girl's soul was still alive, he hibernated inside her body.After so many tortures, the girl named “Zero” in the laboratory died. But, it didn't end there, when the girl died, something very strange happened, something took control of the girl's body and that same thing escaped the laboratory.It was when Nero what that was hibernating in the girl's body woke up and realized was completely naked. In addition, he realized that he turned her into a beautiful winged woman with white hair and some pink strands.

Crossing to One Piece world, he became Roger’s younger brother.
