Rules

Another day passed and Sirius and Zero could be seen again outside the fortress training with weapons again.

This time Sirius was not training with a sword but a spear.

"Once we have your mastery of all the weapons, I have taught you to reach beginner level, then we will continue with other activities. It shouldn't take up much time considering your potential."

"I thought yesterday you said I had no potential." Sirius made a fake gasp and exaggerated his body movements.

Zero's brows twitched, "I see you want the training to be even rougher, well I'll give you what you want."

"I'm good." An immediate response by Sirius!

Sirius lightly chuckled. He tried to lessen the tension between the two ever since "that time".

Despite the short grudge against Zero that was buried deep in his heart, he knew that it was best to bury it further if he wanted to gain everything, he can from Zero.

"Get in your stance and let's go again." Zero got in his stance as well as Sirius.

"I'm too old for this shit." Sirius joked as he panted on the ground with sweat dripping down his forehead and new bruises born on his body.

"Speaking of age, how old are you?" Zero asked.

'How old am I? Wait, how old am I?' Sirius repeated in his head as he realized that he didn't know his age when he came into this world.

'I was 16 years old in my past life, so should I just keep that age in this life too? When I checked the mirror, I did look young, but I didn't know how old I was since sometimes even adults look as young as children.'

"How old do you think I am?" Not deciding for himself, he decides to have Zero decide.

Zero cupped his chin with his index finger and thumb and carefully inspected Sirius. "Well, judging you by how you look and more so your mental age during the short time I have spent with you and since you also have closer height and mental age similar to my daughter. I'll say you are about sixteen years from birth."

'Wow, you really accounted for all of that. Wait? His daughter? This is the time to ask the question I have been meaning to ask since I first heard his last name was Partas.'

"You have a daughter?"

"I never told you?"

Sirius shook his head. "All we ever really do is a train or talk about things that involve training."

Zero thought about it for a moment and then shrugged his shoulders. "Well, my daughter looks about the same age as you so maybe that was what first attracted my attention to you,"

Zero walked to the bench he had created a few days ago because he didn't want to stand all the time while watching Sirius train. Sirius, seeing Zero sitting on the bench, went and sat next to him since he knew that Zero was about to tell a story.

"Many years ago, my wife passed away, so I took care of my daughter most of the time and taught her how to survive. I taught her everything I know but maybe that was just too much,"

Sirius kind of wished he had popcorn since he was hearing everything personally from the father of the main antagonist of Akame Ga Kill.

"I taught her what I am teaching you even though I was definitely easier on her than I am on you." Zero laughed a little while Sirius had a dark expression on his face but then Zero's face turned melancholy and he sighed.

"I taught her the rule that I teach you, the strong rules the weak, and the weak are mere ants in front of the strong and they deserve to die. I have taken you hunting with me once, so you saw my methods."

Sirius couldn't say anything, and his face scrunched up at the memory of Zero gutting a wolf while it was alive. Zero's methods are brutal and don't care for the pain the animal faces.

Seeing Sirius's expression, Zero knew what he was thinking, "I taught my daughter that method and it seems I am getting more and more worried about her mental state,"

"However, this is a way to get strong, a way to keep your mind strong and ignore the mercy and cries of the victim."

Zero sighs once more, "It's hard to raise a daughter without a mother. My wife was kind and that is something that she gave my daughter, but it seems the more I teach you and the longer I raise her, the more she becomes like me."

Sirius finally realizes the true past of Esdeath but he knows that the reason that Esdeath was the main antagonist was because of the man next to him, but he also knows that the reason why Esdeath got so strong and survived a long time was also because of the man next to him.

'You can say that the man who created Esdeath was Zero.'

Zero sat up and looked at Sirius,

"Alright, no more of this. I can't believe you got me to spare you a few minutes of rest when you weren't supposed to. For that, I will train you even harder today."

'What?! Noooo!'

"Oh, I also forgot, Yesterday I sent one of my subordinates to invite my daughter over to Newcastle and I will train her with you. We should expect to see her in two days."

"…"

'Ahh, shit.'

"Alright, what are you waiting for? Get up and pick up your weapon. I'm going to give you a beating for distracting me."

Sirius didn't know whether to cry right now or cry later but might just decide to do both.

A girl with blue hair and blue eyes could be seen riding a horse along with two other people who could be bodyguards.

"Daryl, why did father call for me again?" The girl asked.

"Well, your father has been training a boy, so I think he wanted you to meet him." The guy named Daryl responded.

"Oh really? Father is training someone?" The girl's eyes gleamed with interest.

"Are you ready to meet your father's student young lady?" The other bodyguard asked.

"Of course, I will see if my father's student deserves the recognition of I, Esdeath!"
