"Ostentatious."
Black scoffed and fired a kiai against Haruto. He was a bit surprised by the sudden influx of power but he still considered that as a fluke. Although it was just a light attack, it was powerful enough to shatter several massive structure into countless pieces.
*BANG!*
Haruto did not faze as he raised his hand and eliminated the kiai with just a slight motion.
"....What?"
The other side squinted his eyes, not expecting his opponent to defend against his attack that easily. His evaluation regarding the boy had to be changed since it happened twice.
'Incredible.... I feel like becoming a different person, is this really me when I mastered all of Goku's power?'
Even Haruto was surprised on his current strength. Right now he was overflowing with power and energy, the sensation was so addicting as if he was set free from his shackles, far different than when he was given restrictions.
It's not merely an increase of power as his senses were sharpened while he could move his body light a feather for how light it was felt. Even in the case he did not receive an increase in power, he estimated that he could fight ten times better than usual.
"...."
Without saying anything, he launched his fist, sending a strong shockwave across the air. It hit the corrupt god's body, knocking him off the ship as the latter blocked the attack using his arm. But the wave was a bit unstable and slightly damaged the nearby surroundings.
'Looks like I need some time to get used on the sudden increase of power, fighting in full power immediately would not be wise...'
He frowned and analyzed his current situation carefully. If not for the fact his senses true capabilities were 'freed', he might already cause a friendly fire on his own teammates, worse he would severely injured them in an accident.
As of now, the enemy was acting cautious from his sudden 'change' and did not act aggressively but instead tried to observe him more. Seeing this, Haruto decided to make use of the situation and stalled the fight so he could adapt on his new situation.
The effect of the item from Eisha would not last for long, he could only maintain this 'full release' state for at most an hour depending on how hard he pushed himself. He could only pray it was enough for at least surviving this menace.
There's no need to win or even better, kill the enemy as even with his current state, Haruto could not imagine himself able to triumph against the evil counterpart of his source of strength with limited time much less killing him.
"Looks like you've done something to your body, lowly mortal. But you're far too haughty if you think that's enough to stand against me!"
Above them, Black sharpened his gaze and stuck out his right hand.
"!? Oh no!"
*BOOOMMM!!!!*
Haruto was startled and just in a flash later, the ship was blown into pieces alongside the sea around them. It produced a giant hole more than hundreds of meters large. The depth was unknown as the hole was very dark, showing it definitely was not nearly shallow.
Outside of the great hole, several people were hovering in midair with some of them carried on the young man's shoulders. The girls were barely saved by Haruto just before the fearsome attack landed. He moved very fast and able to carry Fia, Elsie, Rikka, and Asami while Selliana was saved by Kaori using her full power Godspeed.
"T-Thank you Haru-kun, that was so close...." Rikka let out cold sweat, imagining her obliterated without traces if she was hit.
"B-But the other passengers and ship crews..." Elsie put on sad looks, the other people was just alerted of the disturbance thanks to Haruto's unstable shockwave attack but they're unable to save them.
"....We don't have leisure to care for other people, El-chan." Asami said with solemn face.
"...." Kaori gritted her teeth and averted her eyes. She couldn't resurrect the people back as they were destroyed into atomic pieces, no matter how great she was, she needed at least some of their core body parts to remain in order to restore their body.
"Nee-san's right, we can think of that later. Right now you should all escape while you can as his attention was back on me."
"....Just make sure you'll come back to us okay?"
Rikka and the others did not hold Haruto back anymore as they're fully aware there's no survival without him fighting. In addition, they knew he wouldn't be defeated easily anymore. Although they're frustrated but they preferred to bit their lip than causing troubles for him.
Haruto nodded with serious face and resolute eyes. He did not say a word but his expression told them everything they needed to know, that's why they smiled and left without turning their heads back.
They headed towards nearby desolate island several tens of miles away. Even if they retreated, they still wanted to observe the situation after hiding themselves by using the projection from Elsie's celestial robe.
"Do you think Nii-sama can win...?" Elsie asked the others timidly.
"""""...."""""
All of them did not say a word to her question because they didn't know the answer either. They focused their attention to the image of Haruto and unfamiliar man in black clothing fighting intensely.
....A few minutes ago, back to the the place Black and Haruto faced each other amidst the boundless ocean.
"Kukukuku.... I see now."
The former observed the latter before he began to laugh eeriely.
"This energy, this sensation, it was a bit different than the Son Goku that I know but somehow or another you have gained access to his full power...."
"...."
"I wonder from which timeline did you take his power young mortal?" Black smirked.
"....Don't lump me with you, a lunatic thieving god. Unlike you, I did not take nor steal anything from him. I am his inheritor and cleaning up my predecessor's mess is my job!!"
The youth charged forward, aiming his fist filled with strength and vigour against the enemy ahead of him.
"Kukuku."
Black kept his laugh and moved his body, easily dodging the incoming punch. He evaded a few more strikes before delivering a roundhouse kick on Haruto's side.
Using his left arm, Haruto blocked the attack, he felt stinging sensation on his guarding arm because of the force contained within the seemingly casual kick.
'Ugh.. what the hell's with that strength, is he really this strong in the original story?'
Haruto was perplexed, Goku's power should not be inferior to Black's not to mention he was utilizing his strength at the time the "Future" Trunks saga was over. He didn't know the exact timeline but at the very least it should be after the Tournament of Power, meaning Goku had become stronger than the time Black fought with him.
"Hngh!"
*BWOOSH!!*
Clicking his tongue inside his mind, Haruto transformed into Super Saiyan 2. He was adapting fast and now ready to bring the fight on the next level.
Even after he transformed, Black still maintained his sinister smirk, as if he was waiting for it instead of raising his guard.
"Kukuku, this reminds me of when I fought against 'him' at that time. The fight ended on my lost but I wonder if you can do the same this time, mortal?" His grin grew wider.
"Heh, who knows? ...But at the very least I'll make sure to wipe that grin out of your face!!"
*BANG!!*
They both moved at the same time, ramming their fist against each other. It produced ringing sounds as the space around them was making ripples and tremors.
*Whoosh!*
Black let out his pitch black aura and thrust his leg to the front but Haruto dodge it by tilting his body, countering with his own horizontal kick to the former's flank.
"Gu!"
The attack successfully landed, drawing a groan from Black. He tightened his face and grabbed the leg on his flank using both of his hands.
"Haa!"
Gripping the leg, Black flipped Haruto's body and threw him downwards fiercely. The youth was launched like a missile, crashing to the deep blue sea that caused a towering splash as large as a massive building.
*Fwip*
A few seconds later, Haruto appeared on Black's behind using Instant Transmission but the latter had predicted his action and immediately conjured energy blade to slash to the person on his back.
Haruto ducked his head to avoid the attack while a barrage of ki blasts bullets came towards him before he managed to regain his posture.
*BOOM!* *BOOM!* *BOOM!* *BOOM*
The energy bullets missed their target as he flew around the air. Some of them hit the sea below, further making more holes and craters that was no less smaller than the first one.
Haruto created several destructo disks on his palms, throwing them all at the same time om various directions.
"Useless little tricks!"
Black used his energy blade to cut the destructo disks in two. They're all destroyed into particles of lights.
"Over here, you dumbass!"
"Guha!?"
Making use while he was distracted, Haruto landed a solid blow on Black's face. He continued with several more punches before making a backflip kick to the opponent's head.
"...."
Even after having the advantage on the fight, Haruto did not feel happy at all. After all, the opponent was yet to show his power yet, there's no way he's just amount to this much.
"Kukuku...hahahaha!"
Just as he expected as Black flew back from the sea with maniacal face and laugh. He didn't seem to be injured at all despite receiving some critical hit blows on his body.
"Subarashii, your strength is more than I expected, even more than the Son Goku I last fought with! This makes it worthwhile of troubling myself to come all this way!!"
*BWOOSH!*
He yelled loudly as golden colored aura erupted with brilliant light. Black transformed to a Super Saiyan, dramatically increasing his power.
"Tch..."
Haruto was expecting this so he was not all that surprise, but it still made him frowned with grim face because the energy coming out from his opponent was surpassing him by quite a large margin.
"Show me what you're going to do now, Son Goku's successor!!"
"Guh...!"
In an instant, Black close the gap between them and launched lightning fast strikes that had vastly different power and speed compared from before. Haruto was barely able to guard his vital spot but his solar plexus received direct hit, dealing significant damage.
*BAM!*
The evil god struck Haruto's chin using his knee, following the attack with a solid right hook to send him flying several kilometers away.
He chased after the launching figure with face full of maliciousness and enjoyment. After spending countless time on his 'prison', most of his emotion was lost as he forgot how it feels like to have a real battle. Not even he was exempted from the trait of a Saiyan after stealing Goku's body.
And now in addition for finding the successor of his arch-enemy, he finally remembered the joy of fighting with a strong opponent, making his way to the ultimate, limitless power he once sought after growing envious of the godly Saiyan's power in the far long past.
"...."
The two people faced each other silently once again. The first to break the silent was the young boy with blood trickling from his mouth.
"It seems you've gone through a lot of things, growing in such absurd rate."
"Kukuku, are you done stalling with time, mortal?"
"....So you've realized." Haruto narrowed his eyes, he was enduring the fight in order to adapt on his power but was seen through.
"Of course, do you lowly human think you could fool a god's eyes? Ridiculous."
"...."
"...."
The two people became silent.
The atmosphere on the vicinity was becoming tranquil and serene despite the chaotic situation just slightly before. It was so awfully silent that it felt eerie like a calm before the storm.
*Whish~*
Wind breezed across the duo Saiyan, fluttering both of their golden hair.
After a few tens of seconds of silence, both party began to make slight movement, they both clenched their fists tightly to their sides. And then two of them was gleaming with two different colors. One of them started to glow with cyanish light while the other started to glow with pinkish dark red light.
""Haaaaa...""
