A human about 18 years old was walking through a black forest along with the lunar duo behind him. The atmosphere was dark, like there was nothing else living. The human sighed a bit before talking.

"... So it's time... isn't, Cress? Dark?" the two legendaries looked away from him a bit, in their own way of saying it was. He sighed and stop. "Then we have to do it here..." he took a stick and drew markings on the ground.

When he was finished, he took out a pokeball and let out his buizel. The weasel was confused at what was happening. his trainer noticed that and told the water type. "After what will happen... You can't be my pokemon anymore... Sory Surf... This is when we have to part ways." the buizel was surprised and didn't wanted to leave. The human sighed. "We can't do anything else to save this world, Surf... I'm releasing you now. You're a wild pokemon again but... Make sure to keep her and your friends safe... Okay?" Surf still seemed to not accept what his trainer said, but then nodded and left.

He smiled with relief and then turned to the center of the markings on the ground. Cresselia went to his left while Darkrai went to his right. "You two are always with me on those sides... But this time it's because it's needed..." the two legendaries readied an attack as he talked.

But something that wasn't supposed to be there came.

"Huh!? What are you doing!?" a girl about one year younger than the boy came and ran to him. "! Don't come close-" before he could finish, the lunar duo released their attack with both humans at the center and they were engulfed by a blinding light and disappeared.

Cresselia floated back in surprise of the girls appearance. Darkrai seemed to had lowered his head.
('We can't do anything to bring the other back to normal as what he would have wanted...')

Cresselia sighed and went closer to where the humans used to be.
('I know, but that girl was the one he cared for the most... And mostly my trainer.')

The nightmare pokemon looked at the sky.
('... If you want to see them both that badly, let's just go ahead and watch over them. And like before... you and the girl, me and him.')

Cresselia nodded and floated away while Darkrai had sank into the shadows.

... Almost everything went good... Why did she had to come... But what we had done... Isn't reversable... And worse part is... She's probably going to keep her memories...
While I wouldn't.

The boy thought as he slowly felt himself changing. His memories were being wiped out of his mind. Last thing he saw before getting unconscious was a bright, green forest.
