Everyone Else Has a System

Merlin Rose, her full name, Merlin Rosaline Luna, one of the SS-Rank in this world who is hidden from the world's eyes. She is said to be someone who has arrived from the moon itself, which in essence is true, but overall an intricately fabricated lie. Her parents came from the moon and she was born on earth, though they died a few years after the war between Luna and Scarlet broke over a millennium ago.

To be honest, it was more of a one sided annihilation than a war. Still, some strong ones did end up surviving from the losing race. That includes Merlin and a few more hidden ones throughout the world. They are still in hiding because the ancient surviving Scarlet's are still on the hunt for them.

Now, why are the Scarlets still hunting the Lunas even after millennia? That is because of the blood and mana pool. Does the blood of Luna taste good for the Scarlets? Ha! No, it's just the opposite, it is a lethal poison to Scarlets. In other words, Lunas were a potential lethal threat to the Scarlet and will always be. Their blood burns the Scarlet's blood, creating an explosion that is no less than a hand grenade. Though dwindled, the number of Luna is still in the thousands, currently, if I remember correctly.

And other than Merlin, there is one more Luna with SSS-class hiding in this world, living with the other Luna survivors, gathering strength to strike when the time is right.

......…..

"If I use my most powerful move without holding any kind of weapon…. I can obliterate 10 generation's worth of your people in a single strike. Happy now?"

With these words, the atmosphere turned silent. Zero kept smiling at the others with a humble smile that looked more like a devil's rather than a child's. He then observed Williamson's shocked and half panicking face before speaking,

"That skill will be useful for your generation. I wouldn't have shown it if I had the choice. Trust me, it is for the benefit of all of us if you comply… So would you like to make a deal?"

Looking at his expression, he hesitated a bit before speaking,"Can I make a call and then respond?" And I nodded at him. I kind of knew who he would be calling, as there was only one person above him at this moment.

After a few moments of silence, Williamson hurriedly comes back as he speaks,"we accept your condition, but we have an added condition of our own."

Observing the traces of shock on his face, Zero observed him with a little bit of curiosity as his lips curled a bit upwards and narrowed at him. He took a step closer to Williamson as he spoke,"and what would that be?"

Williamson observed him for a few moments before gulping and then speaking,"You have to meet Lady Merlin." Hearing his words Zero's eyes opened up a bit with a sudden realisation as he looked at Williamson with a slight smile on his face despite him trying to keep his composure.

'So she wants to take a risk, huh? Oh! How sweet the lives of Luna are! Revenge resides deep into their hearts, making them burn on the inside, until and unless they set themselves free from the curse of their oaths,' Zero thought as he kept his focus on Williamson, who was waiting for his response.

On the other hand, Annabeth had her eyes widened as she looked at Zero, while Elle had a slightly confused expression on her face. Eliza, on the other hand, just stood at a distance and watched the whole thing play out.

In fact, she had a small smile as she saw Zero making the Rose dance within the palm of his hands without even a fight.

"Well… that shouldn't be hard for me, all right? Then we will go with the first deal. You will provide me your complete assistance when I ask you to do so," Zero spoke and then took out a mana contract before beginning to write on it. After a few moments, he threw the contract towards Williamson, who was still in his stupor. While Merlin did ask him to accept Zero's condition. He did not know whether it was just for the second condition, that is to 'not kill' a certain person, or for all the conditions which Zero mentioned.

Though by the time he caught the mana contract, Zero had already vanished from there as if he had never existed. He tried to sense him but for some reason, his senses were partially blocked and from the looks of it they won't be back to normal for another minute or so.

Instead of finding out where Zero went, Williamson looked at the contract and began reading it over and over.

Each and everything was more or less perfect. With the points mentioned in the contract, the Rose Family should not have any problems whatsoever. Though just for surety, he kept checking over and over until he was 100 percent sure about the whole contract being safe without any possible loopholes.

Basically, other than the above-mentioned points, it also included the point of Zero having to teach Elle and Anna, the Pearl of the Moon Goddess, with some extra moves that could be beneficial to the Rose Family as well.

"Annabeth," Williamson said as he turned to his granddaughter and continued with a serious voice,"I want to know everything that has happened without missing any detail."

Annabeth nodded before

-Tring

A message came on Annabeth's smartphone as [How about you start from looking into your brother on how he managed to get the Red Gem?]

Annabeth's face became shell shocked as she looked at Williamson, who, a bit curious about the message, moved closer to her before noticing the message. However, rather than a surprised expression, he narrowed his eyes at the message and then turned to Isaac Rose, who was still inside the trap.

Williamson waved his hand, and the trap unlocked before he saw his grandson escaping out of the room and then glaring at Williamson before shouting,"what the heck was that for?!!"

His eyes were bloodshot, looking for an answer which he couldn't get no matter how much he thought. He thought of certain possibilities of his plans being discovered before he dismissed them, as everyone involved in that plan was dead except he himself.

"Isaac… why don't we sign a mana contract and have a talk?" Williamson spoke and Isaac narrowed his eyes at him before looking at Annabeth and Elizabeth, who were also looking at him with doubtful eyes.

Before anyone could react, Isaac spoke a chant,"[Selbstmord]" and Williamson arrived right before him… however, his body began melting before turning hotter and hotter.

"[Prison Of materials]" Williamson spoke and a transparent wall of prison formed all around the melted body of Isaac. Just after a few moments, the body exploded into pieces before everything evaporated into air.

Williamson looked at that art and sighed before shaking his head as he said,"he escaped, huh? To think he knew that art at this age… Let's hope it doesn't create any big trouble for us…" before turning to look at his granddaughters.

"Let's go, I will escort you to the Arcadia Academy from here onwards. Tell me the rest of the story on our way," Williamson spoke and began walking towards the lift and Elle, Anna and Eliza moved with him before Eliza spoke.

"I am leaving now." as she moved inside the lift and then sighed as she waited for the lift to go down however…

Williamson shook his head as he spoke,"young girl, you know too much. You are coming with us."

Hearing his words, Eliza's eyes narrowed, and she turned to Williamson, who was looking at the door as he was in deep thought. She pondered over the decision on what she should do from now on. The lift reached downward, and the door began to open as she finally decided to make a run for it, however, before she could do so…

-Ding

The lift gates opened and a familiar face was standing in front of Williamson and the party…

"I have come to pick you up," spoke the blonde haired middle aged man, William Laurentz, as he smiled at Eliza and then observed the face of Williamson, who looked like he was ready for a death battle.

'He is strong… who is he?!' Williamson thought, looking at the blonde man in front of him.

"Now! Now! There are children here. Let's do our own work and not interfere with each other, shall we?" William spoke before taking Eliza away from them and Eliza looked at him a bit surprised as she asked,"how did you know I was here?"

William, not hiding anything, spoke in a slightly high voice so that Willianson could hear,"Zero sent a message about 10 minutes ago, saying it would be better if I were the one to pick you up from this place. Though I did not know what it meant, I thought it would be important, so I came here as fast as I could."

Williamson and the rest gulped as they heard his words, even Eliza was surprised before she smiled at the foresight and thinking process of Zero.

Eliza and William soon left, leaving Williamson and his granddaughters in a stupor before all three sighed before moving towards their destination as Williamson spoke,"tell me how you met that girl too."

Annabeth nodded on that too, as she couldn't help but wonder if meeting Lucia was really just a coincidence. Was it Reaper's plan as well? Just how far has that guy calculated… and what exactly is he planning to do?

Her eyes were slightly shaken as she couldn't help but think that whatever Zero was trying to do… no way in hell it was going to be a small thing.
