Everyone Else Has a System

Williamson Rose.

That was the name of Elizabeth Rose and Annabeth Rose's grandfather. He was one of the strongest men in the world currently residing at 21st position on the world strongest person's ranking.

And just now that man helplessly watched his granddaughters being attacked by a swarm of Demons on their flight towards Arcadia Academy.

He wanted to save them, but the distance was too far and the best he could do for now was to ask one of his henchmen, Viscardi Zelretch, in Arcadia country to run towards Bryxton's Lake and save his granddaughters.

With each passing second, his heartbeat was in a frenzy as he watched his precious granddaughters, Annabeth and Elizabeth, almost being killed multiple times. Whether it was during the flight of after they jumped off the flight, or even after they fell down the lake.

Watching Annabeth turning into a demon with blank eyes, he looked like he had aged by a decade in that one moment. He didn't know what to do anymore… one of his granddaughters was almost gone… and the other one was on the verge of dying, given the situation.

He then watched those men fighting against Elle and Anna; his fury rose as he watched one of the men crushing Elle under his feet. He had already decided what he was going to do with that man… even death would be a blessing for that man, after what he had done…

-Bang

Suddenly a black-haired kid appeared wearing a cloak and kicked that man away. That kid glared at that man before proceeding to heal Elizabeth. Soon after that, the kid displayed some extreme skills in mana control and scythe wielding. He deflected each and every bullet that came towards him.

Soon that kid killed one of the men swiftly with his scythe, without showing any mercy. This kind of demeanour really impressed Williamson. Right after that, someone else entered the battlefield… Rheo Delacruz.

"Mark Leeway sent his regards," Rheo spoke to that kid and that kid simply looked at Rheo. This made Williamson really curious about that kid in the black cloak.

-Whoosh

Then Viscardi came and Williamson was finally relieved that at least Elizabeth would be saved. Looking at Annabeth, his heart ached as memories of the past filled his mind… he didn't know why this happened to her… he wanted to save her at all cost… but alas no one who was turned into a demon… has been turned back to normal. There was no way of saving her and he knew it… the only way to end her suffering would be to kill her swiftly so that both she and those around her would be safe.

He then saw Viscardi moving towards Annabeth and braced himself for what was supposed to come, however…

"Rheo… stop him," that kid spoke as he began looking at everyone around and taking deep breaths before moving towards Annabeth

What that kid said next made everyone feel goosebumps on every inch of their fibre. Whether it was Elizabeth, Williamson, Rheo or Viscardi, everyone felt a slight chill in their body as they saw that kid moving towards Annabeth.

For some reason, nobody doubted his words. They just simply watched him moving towards Annabeth with a slightly tired expression. And then he chanted something they had never heard in their entire life.

...…..

Zero moved towards Annabeth, who was still chainbound. He put his hand on her forehead and then he spoke,"Spirit Summon: Arcadia's True Form."

The air around the lake started swirling much more violently as a being that shouldn't be present in this world took its first step right behind Zero. Looking at that being, everyone felt a chill down their spine as they stared blankly at what was happening.

It was a beautiful woman made up of white aura as she looked at Zero with a confused and complicated look. Her eyes seemed like she wanted to ask how does he know this sacred magic and how can he use it despite him not being one of the blessed races… still knowing the gravity of the situation she spoke with regret,"with the amount of mana you have, the max I can do is stop her for a second. I can't purify her."

Hearing her words, everyone looked at both Zero and that spirit and wondered what Zero would do next. However, Zero didn't look like he was troubled with that. He simply moved his hand… towards Annabeth's forehead and forcefully took out the stone from there.

Before they could get shocked at his previous moves, he did something unbelievable again, he slashed his hand with his scythe and pushed the red stone into it. The red stone rapidly began getting absorbed into his body from there. Zero looked at the Arcadia Spirit with a slight smirk as he spoke.

"I will return in 5 minutes. Keep my body stable till then, you can do that much, right?"

Arcadia blankly stared at him, turning into a demon, and she immediately blocked his movements from the inside. She won't be able to change anything outside of Zero's body, but since he was her summoner, she had enough control over his movements.

Though she had no idea what he was trying to do… in fact, the only one who had any idea what Zero was doing was Zero himself.

...

Inside the Demon dimension, Zero's soul arrived, and he looked around for a few moments. He closed his eyes as his mind began rapidly thinking about something.

"What do you think of humans?" A creepy sly mocking voice came from a distance, but Zero didn't even spare a glance at that voice. The Demon moved closer to Zero one step at a time as if he was leisurely taking a walk in the park while he whistled along.

Then…

"Haha….hahahahahaha….hahahahahahahahahahah" Like a maniac, he laughed as he finally realised everything.

"I f*cking solved the mystery!! I F*CKING SOLVED THE MYSTERY!! HAHAHAHAH…" He slapped his thighs as he bent and laughed and shouted. The Demon stopped as he observed Zero with a confused expression.

"What are you talking about, human?" the Demon asked with a curious gaze as he tried figuring out what was going on with the kid in front of him.

Hearing the Demon's words, Zero stopped laughing and then slowly looked at that demon with a devilish smile.

The Demon, sensing something was wrong, became cautious with his approach as he kept observing Zero.

Like a Devil, Zero kept smiling at the Demon and spoke,"wanna know?" with a mocking tone before his grin widened even more when he spoke,"Blood Sacrifice: Second Moon."

And a chill ran down that Demon's spine as he finally realised the grave danger he was in.
