[Grandora City]
As a person who first accomplished synchronization with his weapon, Greg has an abundant amount of experience when undergoing such phase. In fact he is far more experienced in synchronization than the head general of the chaos breaker organization.
Because of that his control, and mastery of such form is truly exquisite as if both weapon and man had become one. Coupling this with genetic lock which breaks through the human limit and achieve a realm above superhuman, he became far more formidable than any opponent that the three sentinels had faced in their past battle.
All three of them realized this fact when the air around Greg suddenly changed as if he himself had become a beast eyeing it's enemy. At this point, they can't afford to underestimate him, as they all entered their respective stance.
In that instant red strings suddenly sprung out from behind him, as it covered Greg's whole body and became a body fit armor which is far stronger than any defensive mechanism in their uniform.
The next moment Greg instantly charged forward, as it suddenly appeared in front of Nueve and blew him away in a single unexpected punch.
Slightly shocked that Greg somewhat caught them off guard and manage to slip pass through their formation, Sies then quickly unsheathed his sword and swung it towards Greg himself. Alongside him Ocho then swung a kick at the same moment when Sies attacked with his sword.
However Greg simply blocked Sies sword with his arm, as a tentacle made up of strings popped out behind his back and pushed Ocho flying away.
After that he left hand morphed into a spiked ball made out of strings, as he swung it towards Sies, only for the latter to parry it upwards and counter him with his sword skills.
"Arachne sword Spider Thread!!!"
Hitting Greg all over his body as if weaving a spider web, Sies manage to attack Greg multiple times, only to be proven futile as the string armor around his body, protected him from such strikes coming from Sies sword.
Due to that Sies then quickly aimed towards Greg's head, only to be blocked again when a string helmet resembling a knight helmet, suddenly to protect Greg's head.
Failing to take him down even to that extent, Sies then quickly jump away when Greg suddenly counter back in brute force.
After Sies jumped away and Greg missing his attack, a huge container suddenly crashed towards Greg, forcing the latter to tank the attack, before slicing the container in half with its tentacle like strings on his back.
But the moment he did this, Nueve suddenly closes in, as it poured out white mana unto its fist and begun attacking him with an initial uppercut. However this attack coming from Nueve was also blocked, as Greg simply glared at him, before sending him flying with his own punch as well.
This time when Nueve was sent flying once more, Sies then re-entered the battle as he swung down his sword, only for Greg to dodge his attack by blinking behind him, before he grabbed his nape and threw him straight towards a nearby crane.
But before he could catch up to Sies, Ocho's had her whip wrapped around Greg, as she used her superhuman strength to pull him for a spin, before she led him to crash towards the polar dormitory building where Nueve awaits in ambush.
The moment Greg crashed at the dormitory, completely destroying the upper floors and destroying the living room, Nueve then didn't gave him a chance to regain composure, as he begun throwing in punches towards Greg's helmet.
But on Nueve's sixth hook, Greg somehow caught his hand, as he clenched his fist and sent out a counter punch towards him. However despite having his dominant being caught, Nueve simply used his other hand and punched Greg three times in an instant.
On his head, on his shoulder, and on his guts. Each punch carries a force yhat was strong enough to destroy a building in one strike. Such powerful attack was currently being tanked by Greg as he tried to fight off three sentinels.
However he didn't give up as a one handed axe made out of string, appeared on Greg's hand, and swung it down towards Nueve's shoulder. But a simple physical swing wasn't enough to penetrate through Nueve's mana defense and durability of his body. Due to that Greg started imbuing his attacks with mana while also finally using his chaso eyes ability.
In that moment Greg's body burst into flames as he became an incarnation of fire that brings down judgement towards the alien invaders.
With a scream, Greg finally broke through Nueve's defenses and manage to slightly bury its axe on Nueve's shoulder, before the latter disappeared by blinking away.
In that moment Ocho from outside had already whipped together a tantamount amount of 300 containers, and made them all drop on top of the dormitory building, which completely buried the whole establishment under the metal.
As if that wasn't enough Sies then appeared from above and used a sword skills which completely destroyed the harbor and sinking everything beneath the ocean surface.
"Descending sword Daraku shita kami!!!"
In one move the place where Kanzaki and the others call home, had completely disappeared, as the whole harbor came crashing and sinking as Sies wreak havoc on the area.
With the harbor completely destroyed to something unrecognizable, Ocho, Nueve, and Sies retreated back on the city streets as they observed the destruction.
"Your shoulder... what happened to it?" Asked by Sies as he saw Nueve's wound
"Well naturally because of him, that guy suddenly pulled out a flaming axe and begun pushing it down towards me... luckily I was able to get away" answered by Nueve
"Just what is happening here? How did that guy suddenly grew stronger? I don't know what he did, but whatever he did had somehow made him get closer to our strength" Asked by Ocho in confusion
"I don't understand why either, we need to report this to Uno, we need to tell him that this people has the means to grow as strong as us" said by Sies
"Indeed! Looks like taking down this world would take more effort than we anticipate" said by Nueve
"This doesn't bode well to me... this is their last fortress, why are we having a hard time destroying it in comparison to other places?" Asked by Ocho
"Its because they are cornered and if they are cornered then they are desperate.... in desperation they will do anything to fight back" answered by Nueve
But just as everyone thought that the battle was over, a dozen of string like tentacles popped out of the sea surface, as it attacked all three of them, forcing all three sentinels to dodge and get away from the destroyed harbor.
Not long after the water near the harbor begun boiling, as the string like tentacles pulled Greg out of water, and flames begun spreading towards the surrounding.
Seeing this even the sentinels forgot who was the invader and who was the defender.
