Thanatos System

Yin thought quick and enchanted the soles of his feet with the black lightning he called forth from above. He sprinted towards Zachary and tackled him away from where the attack was headed towards.

He knew that if he were to pick Zach up and carry him away, he would not make it in time.

The water beam sounded like waves hitting the ground below, that was how strong it was.

Vale Ashford was now rushing at the Seraphim's footing, trying to catch it off guard. But the Seraphim itself was too shook to even move, so it just stood there taking the attacks from the Specter.

"H-How could it be?!" The Seraphim's unnerving voice was absolutely floored.

Vale was confused. "Is it this surprised that we had a third member in our squad or was it surprised that its attack did not reach Zach?" She asked herself.

The Seraphim leaped right in front of where Yin was. It caught him off guard. Yin immediately got up and began to attack the Water Seraphim.

"Why are you doing this, Thanatos?" The Seraphim asked in a sad tone. "She misses you, he has been longing for your touch for millions of years now…"

Yin did not react to whatever this monstrous Archangel said but something peculiar was happening, Zachary saw it first hand as he was looking at Yin from the side. Yin Sohaya's cheeks had tears streaming down from his eyes as though he was weeping.

After noticing it, Yin wiped it off and was confused for a brief moment. "Just what is the connection of these Angels and the System I hold?" he asked himself. But quickly snapped out of it and began pummeling at the opponent right in front of him.

Vale Ashford was now enchanting her blade with the power of the wind and approached the Seraphim while it was still distracted. Zach did not want to be deadweight in this mission just because he was at a disadvantage when it came to his affinity, he picked up his scythe and began attacking in unison with them.

"If I eviscerate these puny humans keeping you chained down, Thanatos, I shall proceed to take you with me."

The Seraphim said.

Yin did not respond but let his fists do the talking instead.

The Seraphim was charging up another water attack, Yin gave the Specter and Zachary a look. They already knew what he meant, the Seraphim still had no idea what his affinity was because he only enchanted the soles of his feet, the black sparks were not that noticeable.

It was trying to make the ground as slipper as possible in order to limit their mobility, plus, the wounds it sustained from the earlier attacks were now beginning to heal.

"Damn, this one is going to be tough. Tch." The Specter said as she clicked her tongue.

Right before the impact of its attack had reached the floor, the three of them cleared out and were now on top of the tree's branches.

"Yin! Now!" Zachary shouted.

Yin jumped down towards where the end portion of the puddle was and called forth the black lightning to hit the water puddle.

The crackling thunderstorms from above came crashing down and electrocuting the water puddle and the Seraphim itself as well.

Yin activated his Binding Chains in order to hold it down at a distance without him being shocked from his own attack.

Vale Ashford took this opportunity to blast it with pure waves of air pressure from afar. Zachary was trying to hit it with his flame spells as well. "You are not able to extinguish my flames without your water attacks!"

Together, they both alternated between Zachary's fire balls and Vale's wind spells while Yin was holding it down. The Seraphim screeched out, it was not expecting that Yin was going to hold it down or that he was a lightning Slayer himself.

"Thanatos! Why do you aid these pathetic creatures!? Leave these despicable monkeys and come with me! She is waiting there!"

Vale Ashford was now looking at Yin. Not because she was anticipating an answer to this provocation, but because it was not a coincidence anymore. There was no doubt, the Seraphim had called him Thanatos two times already.

"Who the hell is Thanatos, Zach?"

She asked the Fire Slayer.

"Believe me, Vale, I am as clueless as you are! Let us dwell on that after we exterminate this thing!" He replied back.

It had been too long ever since Yin used the Binding Chains, his control was far too erratic to stabilize it. He also had not turned many things into dust for awhile so the chain's links were not as long and sturdy as it should have been.

The Seraphim wriggled itself aggressively in order to get out of the conundrum it was in and successfully managed to break the chains into dust.

"There is no doubt about it, your powers, you definitely are him." The Seraphim said with a creepy grin on its face. "Very well, then I will start with your cohorts."

The Seraphim looked towards where Zachary was and extinguished his fireballs with water coming out from the void where it should have had a face in. After that, he aimed his trident at the Fire Slayer. 

"Shit, he is going to throw it! Get down!" The Specter shouted at Zachary but he was frozen in place.

"Am I really going to die like this? Being impaled into a tree by a Seraphim from far away?" Zachary thought to himself as he felt life flash before his very eyes itself.

The Specter jumped towards the same tree Zach was in and attempted to parry the massive trident with her own blade.

She successfully did so but it was not without its repercussions. Her sword was pushed too far back into her that her shoulders were wounded by it as her sword broke off in two.

"Vale!"

Yin shouted from below and then rushed at the Seraphim with his fists enchanted with black lightning.

"A-Are you alright, Vale?!" Zachary could not help but feel this was his fault. "This is nothing, kid." The Specter replied as she removed the blade of her sword embedded on her shoulder.

"I better ask the blacksmith back at Niflheim to have sturdier weapons, though." She joked about the whole situation before leaping down to help Yin who was slowly getting overpowered by the Seraphim. Although he was frightened at the sheer disadvantage in his affinity against this opponent, Zach swallowed his fear and followed shortly after.

Their battle gone on for another ten minutes with the Seraphim clearly holding back, only the Specter was now left standing as she could not really focus on the offensive because of how much the Seraphim was targeting Zach.

Bloodied and bruised, she took out a knife and stood in front of Yin and Zach. "Before you are even able to lay a finger on them, you have to go through me, monster."

"Then I shall gladly pierce my hand through your heart." The Seraphim said calmly.

The attack was stopped by the arrival of someone, though. Right behind the Seraphim was a familiar person. Someone which Yin had seen only once but heard tales of horror about, it was Adam Rosa.

His black single wing flapped about and he had an angered expression on his face. "Are you really one of the Twelve Seraphims if it is taking you this long to finish what you said you would do?" He asked the Water Seraphim.

"H-He is talking to it like it answers directly to him…"

Yin pointed out.

"What the hell are you doing here, Adam!?" The Specter shouted at the blonde SSS Rank Slayer. "Answer me!"

"Be quiet, Vale. I have no time for the likes of you." He said to the Specter right before whispering something to the Seraphim which caused it to back off and create some distance between them.

Adam Rosa's eyes locked in on Yin. "Interesting, so you really did choose to do it, huh?" The white haired Slayer was confused by his choice of words. "What did he mean by 'doing it'?" Yin asked himself. "Could it be that he knows of me merging with the System itself?!"

"The way that you are right now, it is absolutely not worth it to bring you towards the castle in the distance."

The Reaper said poetically.

"A-Adam Rosa…" Zach had already lost hope after seeing him. "There is no way we can take these two on with just the three of us…No freaking way…"

"That might be the case, Zach, but I am not dying dishonorably." Vale said as she turned her head at the boys accompanying her on this mission.

"Come! Adam!" She said while wielding the knife she took out earlier. 

"Do not make me laugh, Vale.. It would be a waste clashing blades with you the way that you are right now. I guess you really are not used to fighting while protecting a couple of weaklings, eh?"
