No matter that Plague Reaper was a Top-1 monster, he was still a Purple Threat monster and not someone who could easily defeat even K3-Phantoms.
Plague Reaper and the Phantoms before him were on the same level and were each other's natural enemies. Golden Light Squad, and especially Adam, were not simple K1-Phantoms, and neither was Plague Reaper just a strong monster.
Plague Reaper couldn't just kill them all in one attack or break their bones with his aura, he wasn't that omnipotent.
Thus, their attacks were dangerous to Plague Reaper, which was why he did his best to repel Erla's shot because he knew what would happen if her attack hit the target.
And... Oskar's massive sword, empowered with light energy from his Second Nexus Trait, was a real threat that could end Plague Reaper's life in one precise swing.
In a few seconds more Oskar's sword would plunge into Plague Reaper's neck, severing his head.
Could Plague Reaper have let that happen? Of course not.
Katrin's roots were holding Plague Reaper in one place, in any other situation he would have been able to destroy them utmost quickly, but now he didn't even have a few seconds.
Tremble. Tremble. Tremble.
The Plague Reaper's coat began to shake vigorously, revealing that the material from which the coat was made was not cloth at all, but something more complex and sinister....
Whooooooooooooosh.
Plague Reaper swung his arm, lifting his coat, covering the right side - where Oskar was. It seemed as if he was going to defend himself from Oskar's attack by putting his coat under the strike.
But... if Plague Reaper only possessed black air and impressive physical power, he wouldn't be able to become a Top-1 monster.
There was the sound of clamping teeth like a piranha before devouring its prey.
Then, a ghastly jaw with many white teeth and four long fangs emerged from the black coat, a long red tongue twitching from side to side in anticipation before a delicious meal.
"Agh...?" Oskar's eyes went wide.
Suddenly, Plague Reaper spat out a clot of blood with a pained face before looking at his right arm, the bandages on which had been torn apart by such a powerful blow.
'I see...' Adam internally muttered carefully studying Plague Reaper's reaction, 'That punch was incredibly powerful, but he won't be able to use his strange coat too often.'
Adam glanced at Plague Reaper's coat whose jaw had already disappeared.
'To do that he needs the coat to absorb someone's flesh, transfer its energy to him, and Plague Reaper will attack, releasing that power but also facing destructive pressure. The recoil would simply destroy his body if he did this several times in a row.'
Adam as well as the others didn't know that Plague Reaper had such a dangerous trump card, but he tried to learn as much as he could about his opponent while he had the chance.
Step.
Plague Reaper stepped forward, but he wasn't heading towards Adam or the others but towards Oskar as if he wasn't done yet.
Oskar's massive sword lay at his feet, he cast a quick glance at the weapon and effortlessly picked it up with one hand.
"What, what is he doing...?" Lero muttered in a trembling voice.
He watched as Plague Reaper bent backward, drawing his sword for a throw, like a spearman ready to strike his target with a precise attack.
"NO!" Adam exclaimed turning into a lightning flash, but it was already too late.
Crackle.
With a cracked stone platform beneath Plague Reaper's feet, he threw the massive sword hurtling through the wind currents, heading straight for Oskar.
Oskar's eyes went up, seeing how his own sword, was about to take his life.
'Fuck... Is this really my end?'
Oskar muttered before his eyes reflected the white flash crashing into his sword.
