Nico Robin was the general of an army. She was known as the Devil's Child, mostly because she had entered the army at a young age, due to the death of her parents.
That was 20 years ago, now she was the army's leader. One night, her superior Trafalgar Law, requested to see her in his office.
"You asked to see me, sir?" asked Robin.
"Yes, I have a present for you, it's in the bag by the door." Law smirked.
Robin carefully approached the bag, she'd known for her entire life that anything can go wrong at any moment.
She opened the bag and saw a young man with green hair. He didn't look older than 20. At his waist she spotted 3 katana.
"What is the meaning of this?!" Robin demanded.
"He's a weapon. He's called the Demon Cutter for a reason." Law explained.
Robin quickly took him out of the bag and laid him in her arms. The boy slowly opened his eyes and looked into the general's eyes.
"He's in your battalion now, Nico-ya. I'm sure he'll be helpful to you and your soldiers." Law said as he bid her goodnight.
Robin couldn't believe what had just happened, where had this man come from? And who was he? She'd be sure to ask Law tomorrow.
"Hi there, my name is Nico Robin. I'm the general of your new battalion. What's your name?" Robin asked the boy lying in her lap.
"Zoro. Roronoa Zoro, ma'am." He replied.
The next morning, Robin went to speak with Law.
"That boy is a weapon, nothing more, nothing less. He doesn't have feelings or emotions. All he knows how to do is fight."
Robin sighed, she didn't want someone so young to waste their lives on the army. There was life after battle, she couldn't let him stay like this forever.
"Zoro, I'm going to teach you how to read and write. Okay?"
Zoro saluted before asking, "I didn't see you at breakfast ma'am, may I ask where you were?"
"Speaking with my superiors about any problems within the military." she lied, she didn't want him to think he was incapable.
"I see, allow me to begin my studies." Zoro replied.
As weeks went by, Zoro was fully capable of reading and writing, even his speech had improved. He still had the obedient tone in his voice though.
Robin noticed Zoro didn't need much physical training, so on the weekends, she'd take him out to see the world and experience what she knew he hadn't before.
Two years went by and they both went through physical changes. Zoro's hair became a lighter shade of green and his build even more muscular than it was before he'd met the general. Robin's hair had grown longer and her skin tone much paler.
"General Nico, Captain Law says we will head into war a month from now." General Franky told Robin one day.
"The day has finally come." Robin sighed as she sat down to eat dinner with her battalion.
"Who was that ma'am?" asked the swordsman.
"General Franky of the Water Seven battalion. He's part of our military." Robin answered as she drank her coffee.
"Is this the last battle?" asked Zoro. It was a huge war between the two countries of Paramount and Grand Line.
"Yes, win or lose this will be the last one." Robin sighed.
Robin met with Franky the day prior to the war.
"What is it? You rarely come to see me." Franky said to her.
"You've said you were starting a business once the war is over. If I don't make it back, I want you to hire and take care of Zoro. And if he asks, it's an order." Robin smiled sheepishly.
"Of course. I'll see you on the battlefield Nico Robin." Franky saluted her as she walked out the door.
Later that day, Robin took Zoro to a street market.
"Hey, it's our first battle together, so why don't we celebrate with something. Pick something and I'll buy it for you. Okay?" Robin smiled.
"What should it be?" asked Zoro.
"Whatever you want. Pick something that interests you." she added.
The two of them walked past stand after stand until Robin stopped as she heard Zoro's footsteps fade away.
"Did you see something?" she asked.
Zoro was looking at a pocketwatch. He watched the hands move slowly and steadily at the best of the ticks.
"You like that watch?"
"What does it do?" Zoro inquired.
"Tells you the time. Remember? I taught you how to read clocks too."
Zoro picked it up and opened it to see an empty slot. "What do you put inside?"
"Most people put pictures of loved ones or people close to them." Robin replied as she poked around at some other stands.
"General? Do you have a picture of yourself? I'd like to buy the pocketwatch." Zoro asked.
Robin gave her soldier a confused look. "Here's the money and I can get you a picture of myself later." She said giving the money to Zoro.
Zoro rushed back to her with the pocket watch in hand. It was an unusual color for a watch. It was a bright blue.
"Zoro, that's quite a unique pocketwatch you have there. Why did you pick the blue one?" Robin asked.
"It reminds of you. Your eyes." Zoro answered.
