3rd person pov:

We see a boy with green hair sitting with a black haired girl under a tree, it was currently day time so they stay under the tree's shade, the boy is 11 years old, his name is Roronoa Zoro, and the girl, who is about 1 Years older than Zoro is named Kuina, they are childhood friends.

Kuina and Zoro was telling scary stories to each other,  Zoro was the one telling stories this time..

"Ok so, here is my story, so Pirates-"

"Pirates again..?? Why can't you tell stories about ghost or something..?" Kuina cut Zoro off

"I..I dont know, but this is a scary story!" Zoro said enthusiastically 

Kuina only noded not believing him one bit

"Ok so this crew saw a ship... and then they heard music.."

"..." She stayed quite letting Zoro continue his story

"and then they saw a skeleton was the one playing the song... and then.."

"BAH!" Zoro suddenly shouted startling Kuina 

"AH! ZORO!"

"Gyahahahahahah! I scared you-!"

"Grrr.. anyways Its my turn, after this we're going back to training!"

"YOSH! THIS TIME I'LL BEAT YOU AND SHOW YOU WHAT THE STRONGEST SWORDSMAN LOOKS LIKE!"

"mhm in your dreams anyways, I'll be the strongest.. even if I am a girl! anyways, so... I heard that there are demons in this world, they wonder the night and eat people..."

Zoro at first was dumbfounded but then was scared.

"hahaha.. y-you can't scare me.."

"and--- Z-Z-Zoro.. w-what's that behind you.." Kuina cut herself of and pointed behind Zoro

Zoro looked behind him frightened, but he saw nothing there, but he was still scared though, that was when kuina pushed him scaring him and making Zoro stumble

"H-HEY!"

"ehehe.. anyways lets go back to the dojo.."

"ok..." 

Zoro and Kuina walked back to the dojo to continue their training, even though Kuina being a girl will be weaker than Zoro, he has never beaten her ever even after 50  spars, but through out these 50 spars they have become friends.

"by the way, how do you kill the demons you told me about earlier..?" Asked zoro

"hmm? why? you still scared?" answered Kuina teasingly

"n-no.. I just want to know"

"Its sun light, or so I've heard, I only know this from dad.."

"o-oh ok then"

and so they continued there way back to the dojo..

Time skip 5 months later, night time

'I've been having the same dream over and over and over again..'

'every night' 

thought Zoro to himself as he is laying down on his futon and looking up at the celling
