Sin kept looking at the sky as it rumbled, and then grinned as a massive blue pillar of lightning fell right towards them.
"Playing with Lightning?" He disappointedly shook his head. "You can create and control it, but it will never be enough against me."
As soon as his words fell, the pillar of Lightning stopped in the air, and then simply disintegrated into specks of light.
"Surprised?" He chuckled before he disappeared from his spot in a flash, rushing towards the Upper Yard, and then up the Giant Beanstalk, arriving at a small Cloud Island, where the God's Shrine existed.
The people, including the women, who were in the harem of the God of Skypiea, and his Divine Servants, all stared at Sin in shock as he suddenly appeared out of a Lightning Bolt, but the tall man who was lying on his side on top of his throne, indifferently looked at him with his half-lidded eyes.
Sin curiously looked at the man's long earlobes, which fell near his chest and held a big red gem in each of them. And then there was the conspicuous grey ring, centrally hooked into his shoulder blades where his Wings were supposed to exist as a Birkan.
On that ring, there were four wooden drums, with four mitsudomoe on them, all associated with a certain Mythical God of Lightning, who was called Raijin.
"A wingless Birkan?" Sin smiled and noticed Enel's eyes narrow at him.
"Are you a God too?" He asked in his heavy voice as he lazily sat up, and then picked up his Gold Trident before standing up on his feet.
"Of course," His smile brightened. "My name is Black D. Sin. And I have taken a liking to your throne and Shrine."
"Black D. Sin?" Enel's brows furrowed as he heard his name, and Sin clearly sensed the rage bubble up in the man's heart. "Are you his son?"
He surprisedly looked at the Birkan and immediately understood who he was talking about.
However, he still decided to ask the question.
"Who?"
"Mors," The man kept an indifferent expression on his face, but his emotions were all over the place.
"No. He was my Uncle." He smiled. "How do you know that Madman?"
Enel kept looking at him, now obviously seeing the resemblance he bore to Mors, especially his cold grey eyes.
"Doesn't matter." He said and then rushed right at him at a speed that any other person would have failed to keep up with.
Sin blocked the trident that was headed for his neck with his bare hand, and Enel's expression remained indifferent.
Just when he noticed a small ring around Enel's pupils, he saw and heard the red streaks of lighting surrounding them, and Sin's heart thumped hard against his chest in sheer excitement.
"Ahahahahaha..." He laughed at his excitement, and soon a dangerous glow appeared in his eyes. "I will give it to you that you are full of surprises."
Twisting his hand and grabbing the trident, Sin threw a kick right at Enel's face, who, to his dismay, effortlessly dodged it.
He sensed the punch coming at his side, and there was no way he could dodge it in time.
A loud thud sounded out as he blocked the attack with his arm, and his brows furrowed at the strength behind it, which sent him crashing into the nearby tree.
He saw the Lightning Bird that Enel had created rush at him, and he simply raised his hand to block it and then ruptured the man's control over it.
Enel finally showed some surprise when Sin created a similar bird and sent it towards him, returning the courtesy.
The God of Skypiea tried to block it with his hand in a similar fashion but failed to rupture Sin's control over it and was pushed several metres back before it exploded.
"I told you. Your control over it will never be enough against me."
Sin already knew that the Lightning attacks wouldn't do much against his enemy, but when he saw Enel come out unscathed, he still sighed in his heart as he felt his blood brimming with even more excitement.
"Let's fight in the sky." He said, and then rushed hundreds of metres up, waiting for Enel to follow him.
A pair of dark greyish-blue wings sprouted from the Birkan's back, wings which he was very familiar with, and then the man shot up in the sky, coming to float right in front of him.
"What Devil Fruit did you eat?" Enel curiously asked, and Sin smiled at him.
"Rumble Rumble Fruit. I am Lightning."
The man narrowed his eyes at him and then smiled.
"A Logia, hah? Truly a power befitting a God."
"Thanks." He nodded. "Mind if I ask you a question?" Seeing that Enel was indifferent about him, he continued. "Where did you find that Fruit? I searched for it in all of Birka after I killed Mors, but I did not find it. And I don't remember sensing you in the city either. Did it spawn someplace else?"
"You killed him?"
The rest of his words were completely ignored, and it was clear that he would not receive his answer.
Then again, he had answered his own question.
"Yes." He nodded.
"You lie." Enel smiled. "A God like him could have never fallen in your hands."
"You revere him, and hate him at the same time." He curiously looked at the Birkan. "What did he do to you?"
"He stole my wings." The man replied and then grinned. "Now I have his powers and his wings."
"Oh," Sin narrowed his eyes as he saw Enel's body generate electricity, and then the two of them rushed at each other at the same time.
The clash in the sky generated loud booms that could be heard throughout Skypiea, and Sin soon realised that something was not right.
Enel, somehow, managed to evade attacks that should have been impossible to evade, and he knew very well that it was not some simple Mantra that was helping him.
Inadvertently, when he was punched in the stomach by his enemy, he looked at the rings around those pupils again, and a very dreadful thought appeared in his mind.
An echo of a memory...
"Watch these eyes, Kid." A face he was very familiar with surfaced in his head, grinning as madly as he always remembered. "These eyes can see things that you can't."
"Damn it." He cursed as he coated his body in pulsating electricity, attacking Enel with an even faster speed, finally forcing the man to block his moves.
He further imbued his body with even more Haki, which finally made his enemy feel the brunt of his hits, but soon, tables were against him again. And his mind soon drifted to another memory...
"Only a fool would fight me to death." Mors madly cackled as he threw the body aside, his hand red in the slain's blood. "Whose going to save you now, Sin?"
In present, a hard hit landed on his side, and he was sent shooting down to the ground.
Clearing his mind, Sin stopped himself in midair and then dematerialised into Lightning as he rushed back up.
"I am the God." Enel declared, just as he controlled the Lighting in the sky, shooting it down at the Upper Yard.
Sin knew where those pillars were headed, and he gritted his teeth as he snatched the control away from Enel, and then sent them all at his enemy.
A loud explosion sounded out, and the light that it emanated was blinding.
*Screeeccchhhh*
A familiar cry of the bird resounded in the sky, and when the light cleared, Sin looked at the majestic Thunderbird in all its glory, and his heart sank a little with he saw the clouds around its neck.
"Allow me to show you the true power of a God," Enel spoke, and then the bird's beautiful wings started flapping, creating a windstorm that soon took the form of two massive tornadoes, dropping right at the Upper Yard.
Sin realises that Bonney, Augur, and Kuina would suffer grievous injuries if the attacks landed on the ground, and he ignored the bird that was rushing at him and created pillars of Lighting to intercept the two tornadoes.
The sight was truly apocalyptic as the two attacks collided with each other, and though he managed to neutralise the threat against his crew, he took an attack head-on by the Mythical bird, which knocked the breath out of him and sent him shooting down to the ground.
He only regained his senses when he was embedded in a large crater, and his eyes vacantly stared at the beautiful bird in the sky.
"Coward," He spat, but then laughed, admiring the plan of his enemy, even if it was quite vile.
Enel had realised that there would be no swift end to the battle if they continued keeping it fair. So, he was targeting Sin's crew to distract him now.
Sadly, he could not employ such tactics as Enel did not really care about his subordinates.
"I told you. There's no way a man like you could have killed a God like Mors. You lied!" The Birkan spoke and then rushed right at him. "And lying to a God warrants death."
"You can see the future. Right?" He smiled as he forced himself up to meet his enemies. "So, do you know what's about to happen to you?"
He coated his body in Lightning and Armament Haki and rushed into the sky to meet his enemy, and Enel's eyes narrowed when he saw a strange silvery-blue Aura suddenly surround his fists.
Dread whispered in his heart as he saw what was about to happen next, and though he nearly dodged the oncoming attack, Sin proved to be much faster than he could cope with at this moment.
A painful cry escaped the bird's throat when a fist landed on it, hurting it, despite the Ren that was coating its body, but then it reacted by sending Pillars of Lighting down at the enemies who were up against his Priest, managing to distract Sin and escape the second fist.
Enel transformed into his Hybrid Form, where his hands were now talons, and the wings of his back were even longer than before. Around his sounders was a circle of greyish-blue clouds, and his eyes were now the eyes of a predator bird, glaring at him.
He wiped off the blood that was dripping down his lips, and then blankly stared at it.
"You are the first to bleed." Sin grinned and laughed when he heard the clouds rumble in the sky.
"I lost my focus." Enel smiled and then laughed too. "It won't happen again..."
