Smirking as the Demon King's power rose to just ten-thousand eight hundred, Hakurei spoke up before the senile old man could. "You think this is my limit, old man? What a joke to think your own strength is so paltry when compared to mine," shushing Piccolo, "No, you don't have the right to speak now, that time has passed so shut up you moron. Now then, prepare for the carefully manipulated feast I've prepared for you! HYAAA!"
Hakurei swelled with energy both released from within as well as attracted from the very air about him. Crimson exploded from all around him like the plume of a great flame as the ground of Terra shook and convexed inwards into a crater. Finally, one quarter of the Mutant's power had been brought to bear. His battle power now rested at forty-two thousand, four times the plateau of the ancient Namekian. "No… NO! It's not possible that such a powerful being exists, not even my goody-two-shoes other half is that strong!"
Lucian summoned a blade of crimson energy along her hand and lunged towards the draconic Cymbal, the blade cutting downwards quickly and shearing the entire right wing from the creature's body and leaving behind a burning sensation. Son Goku leapt into action instantly, delivering a kick that had to have broken the draconic Cymbal's jaw and sent him into the ground. Tambourine was quickly intercepted by Goku, knocking the boy to the side easily and approaching Lucian who had an easier time dodging the attacks of the dragonian.
Hakurei meanwhile, vanished with the application of Zanzoken and appeared to the side of the namekian, avoiding the burst of ki and sending his right arm fingers-first straight into and through the sternum of the namekian. Hakurei's hand, surrounded and swathed with ki, then exit the chest cavity of the Demon King on the other-side with an raucous upheaval of blood of gore. The feared Demon King had been slain before his arrival had any procession to it all! He attempted to speak but instead... he gagged and spit out a large egg.
Hakurei brought his hand back through the corpse of the Demon King, He quickly released a pair of ki blasts, breaking through the binds of Krillin with ease, then stepped towards the battle still ongoing to find that Son Goku was currently in rough shape, that meant that he'd be garnering quite a Zenkai from his fight with Tambourine. By now, however, Cymbal had been handily defeated and knocked unconscious by Lucian. Hakurei smiled to the tanuki girl, then released a small barrage of ki that would fatally wound Tambourine on the spot.
Hakurei sheepishly grinned, not quite able to control his power when brought to this extent. The flaming crimson aura subsided as his battle power was quickly reigned in to reach one-thousand six-hundred and thirty once more though the process took a full minute. By now, Krillin was starting to awaken, prompting Hakurei to look over towards the human. "Ahh, hello Monk. You've been saved from your fate and I'd like for you to join my brother here in training with the Turtle Hermit, Muten Roshi."
"The legendary Roshi-Sensei? Well, there's no way that I'm going to say no to that!" exclaimed Krillin loudly, clearly excited to be able to train with such a legendary figure in the world of martial arts. With that settled, Lucien quickly clapped irons on both draconic mutants and quickly hauled them off to West City Police Department for judgement by the world government. By the time she returned, Son Goku and Krillin had already departed. Hakurei had already taken stock of the castle while she was gone.
"So... What's your plans now that there's nothing in the way of peace for the next untold years? I know that look in your eye, you've got something planned. What is it?" spoke Lucian curiously. Hakurei let out a deep sigh of the sorts which Lucian hadn't seen in the mutant to date, almost as if he was an old soul on the inside and knew that things would not simply end with the demon king, that there was more stresses to place firmly on his shoulders. Well, Hakurei was like family so whatever they faced it would be together.
"Six, maybe seven years of Peace... followed by a threat that makes Demon King here look like a kid playing with matches. They are the same race as Goku - the Saiyans - and they will be coming with a vengeance. I've already got Bulma working on a machine to make training easier, and we will need to train hard to defeat these enemies that will be coming our way... That power which I displayed just won't be enough. I will need to step back with my own training and prepare you all."
"Then let them come." spoke Lucian, giving her friend a hug.
