Author-chan; Hehehehe...
*calls Ivancov by Den Den Mushi*
Ivancov; Hee Haw! Ivancov here!
Author-chan: Can I borrow your Epolio Female Hormone nail and Epolio Male Hormone Nail?
Ivancov; What's that for? HEE HAW!
Author-chan; Gender-bending. Send Sabo over with them. I'll use him too for it...
Ivancov; Hee Haw! I'll get it ready as soon as possible. I need a price later.
Author-chan; Sure, Sure.

I woke up with 'that'

"Arrrrgggg!!!" was heard from the deck.
One by one a scream was heard. Brook who was absolutely clueless went out to the deck to see a girl with green marimo hair. She was in a green clothing that Zoro was wearing.
"Ummm.... Who may you be?" Brook asked.
"I'm Zoro. How the f*ck am I a female?" He questioned.
Zoro's voice was higher than usual.

"All the females turned into males," (y/n) added as she walked towards Zoro. 
Her voice was deeper. Her (h/c) hair was shorter and her eyes were (e/c). He had a very toned body.
"WHY DO YOU HAVE A BIGGER BREAST THAN MINE! IS THIS HATE!" (y/n) yelled as she tried to rip it off. 
"OI! Are ya trying to kill me!" he shouted. 
"Ummm... Why are you half-naked?" Brook asked.
"I sleep with a shirt. Is it wrong?" (y/n) said, "Plus I'm a male now."
Nami popped behind as well.
"Though, I think it's a bit embarrassing." she.... I mean he added (Nami), "Also..."
Nami had a little deeper voice too. Still, though she had the same fashion style.
"Could you give us some clothes. Some boxers too if possible." Robin said as she walked around half naked too.
Robin had short hair and blue eyes. It was a marvellous scene for fan's to see.

Zoro stood up to get some clothes. Until the ship heard a Luffy-ish scream from the captain's room. A little red figure popped out.
"(y/n)-nee!! I turned into a female!" Luffy shouted.
You could see the shirt was about to rip from the size of his chest.
"Luffy. Follow me. You need a few thing to get changed." (y/n) said, "We need to switch clothing."

(y/n) followed Luffy into the female rooms to get changed. While Robin, Nami and Brook wait for another scream.
"AAARRRRGGGG!!!" this time it was Chopper.
Chopper ran around with a panicking face.
"I'm a female reindeer now! What's going on!" he... she yelled (Chopper).

Chopper actually looked like a woman human for once. Robin and Nami giggled at the scene. The boys were the one that panicked the most. (y/n) came out of the room with Luffy in (y/n)'s clothes and (y/n) in Luffy's clothes. Luffy was rather beaten up though.
'Why did I have to get pulled?' Luffy thought. 
'Why did those breasts be so stretchy?' (y/n) grumbled. 
"Hey! Where is Sanji? I'm hungry." Luffy said.
By the mention of the name the ex-females sweatdropped. You can't image what he might be doing.
"I'm a woman!" Sanji cheered as he ran out of the room.
Her (Sanji's) voice was a little higher but he looked rather same but with long hair. Sanji then stopped when he saw Zoro. 

"Why are your breast bigger than mine!" Sanji yelled.
"I don't know but these are annoying. How do Nami and Robin fight with these?" Zoro asked.
"HEY! I MAYBE FLAT CHESTED BUT I STILL HAVE ONE TOO! NOT NOW THOUGH!!" (y/n) yelled in anger, "THIS IS DEFINATLY HATE! I WILL PULL THEN OFF! 
Franky then came out. He wasn't 'that' surprised.
"I thought this was a dream! But this is SSSUUUPPPPERRR COOL!!" he yelled.

Everyone was laughing at each other and fighting each other. Franky had a bit of a big stomach though. (y/n) then walked over to him and put a hand on her (franky)'s shoulder.

"Thank you." (y/n) muterd.
"I don't get it." Franky said as he tilted his head. 
Until someone noticed one thing.

"Where's Ace and Sabo?" Luffy asked.
"Sabo is probably asleep. He did a delivery for Author-chan." (y/n) answered.
"How about Ace?"
"He's ... I forgot.. He had no shirt."
(y/n) slowly walked towards the guest room on Thousand Sunny.
(y/n) knocked on the door.
"I'm not letting anyone in!" Ace yelled from inside in a rather feminine voice.
"It's me! (y/n)! I came to bring you a shirt." (y/n) said. 

Ace instantly opened the door pulled (y/n) in and closed the door.
"Sabo came into my room and we are hiding here since the morning." Ace whispered.
Ace kinda looked.... cute...

"Oh, it's fine. I've become a male too. Everyone became opposites... Except for Brook. He became.... neutral?" (y/n) stated.
Sabo came out of the blanket that covered his body.
"What are we going to do?" they both asked.
"I don't know!" (y/n) replied.
(y/n) then pulled the blanket to reveal him. 

'He looks hot as heck.' (y/n) thought. 
"HEY! Stop your bloody nose!" Sabo shouted.
(y/n) quickly rubbed it off. 
'He still has a bigger chest than me' (y/n) grumbled. 

After getting changed (y/n) forced them to go out of the guest room.

Sanji was trying to peel all the clothing to look at himself while Robin stopped him. Nami was trying to electrocute Luffy for having a bigger boob than her. Zoro was sleeping and Brook was simply having tea. 

"Brook, did you change?" (y/n) asked.

"I think I changed. I feel no difference though." Brook said as he sipped some tea. 

(y/n) then glare at me. What can she see me? 

"AUTHOR-CHAN! IM GOING TO KILL YOU!" she yelled at me.
'Crap' I thought before running around. I was about to go past Zoro until I tripped over his leg. 
"Author, I'm going to kill you for this," Zoro grumbled as he got ready to slice me up.
"KKKYYYAAAA!!!" I shouted. 

I think every single one of them were looking at me now.

"Ummm.... HI!" I awkwardly said.
Some death glares were sent my way.

Zoro, Luffy, Sabo, Ace, (y/n), Usopp, Nami, Robin and Chopper were chasing me now. I dashed for safety. 
"Bye!!" I yelled.

NO POV

Author-chan ran around. Most of the crew were chasing her until they lost her. 
"Where did that dawn Author go." (y/n) said.

"I will kill her." Zoro grumbled, "This chest thing is in my way."

"The nails of Ivan's was probably the one that changed us." Sabo explained, "How do females fight with this?" 

"My back hurts. Probably because of this." Ace puffed.
"This chest is annoying" Chopper huffed as he tried to pull it off. 

"I think I would like to stay male." (y/n), Robin and Nami said in union.
