"Are you ready to watch the execution of the previously acclaimed champion of this COLOSEUM!?" An announcer says as the crowd goes wild once the older folk in the stadium recognize the beat-up Buster from decades ago, the one who defeated the previous Emperor and earned his freedom.

  "Holy shit, is that Buster?" "No way, that's Buster?" "Geez, he looks in bad shape, and all his hair is gray now. Why is he back?" Most people started questioning what someone like him was doing in that Arena, and so did Buster, who had a couple of his bones broken by the Emperor himself before sending him to the Colosseum.

  'This place brings back bad memories, but if this is where I die, then at least let's give a good show.' Buster thought of standing up on his good leg, which was his right leg since his left leg had been fractured the morning before. The cage around him soon dismantled itself at the click of the Emperor's hand, finally letting everyone see the beat-up old guy standing firm in the middle of the Arena.

  "And to challenge the previous champion, we have none other than the current popular warriors of the Colosseum! THE DEATH STALKERS!" The announcer screams into a microphone-like device that amplifies his voice, making the people even more excited as the younger, healthy-looking fellows show themselves in all corners of the Arena.

  The death stalkers were a trio of warriors who had been dominating the current fights and were practically unbeatable. Only a death stalker could take on another and vice versa, with them being two guys and one girl. The two guys wore regular clothes for Coloseum fighters, with them using as little armor as possible, a small round shield, and a short sword.

  The girl, on the other hand, was the one with a lot of gear. She almost used an entire body armor with small-scale cuts of metal all over her body, like the skin of a reptile. "Tell you what, old man. Because you're a legend, I'll end your suffering in two seconds!" One of the guys says to Buster as he cracks a smile.

  'If beating these guys will allow me to stay alive, then forgive me for breaking my promise, Alexandra; I will kill in the Colosseum again.' Buster's thoughts went straight into the previous love of his life, a woman he loved. A woman Buster promised he would never participate in Colosseum duels ever again, but as always, fate had other plans.

  "KP ENGINE! GRADE FIRST!" The all-too-usual steam from the KP technique soon manifests in Buster's body as well, and his wounds start closing up while the announcer continues to speak. "This will be a no-holds fight! THE ONLY WAY A WINNER WILL BE DECLARED IS WHEN ONE MAN OR WOMAN REMAINS STANDING!"

  The people in the Colosseum all start cheering for whoever they choose to place their bets on, albeit most placed their bets on one of the Death Stalkers instead of Buster, as only the old folk bet on him, remembering how he used to fight in the past. "And now prepare to hear the start of the duel from the only one great enough to receive such honor! EMPEROR MAIDAS!"

  The announcer suddenly hands over the microphone-like device to the Emperor, who reveals himself to his people with his usual attire, which is a red cape and robes that barely cover his upper body, letting everyone see the perfectly shaped toned muscles of the king along with all his red tattoos.

  The people all cheer when they see their dear leader in good health and looking better than ever as he continues with the announcements. "Decades ago, this fighter earned his freedom with a duel against my father, but now he is back to entertain all of you with possibly his last DUEL! LET THE GAMES BEGIN!"

  The Emperor's sharp eyes direct their attention toward Buster's eyes, which are quickly met with fierce determination from the retired fighter. The Emperor, for once, felt fear down his spine as the match of 3 against 1 took place below his feet in the Arena of fighters.

  "YOU'RE MINE OLD MAN! DOORAA!" The first fighter quickly rushes against Buster, who doesn't even bother dodging him, instead choosing to grab him and hold him against the upcoming secondary guy, forcing them to run around him again as he prepares his third-grade technique.

  "This piece of shit thinks I am surrendering that easily!? What do you say, bones!? AHHHHHHHGG!" Buster's incredibly powerful aura suddenly falls upon everyone as his body steams like crazy, covering the entire stadium with a fog that is so thick and hot that it makes everyone sweat like little piglets!

  "UUUUUUUUUUUHHhHGGGG! EHHHHH! AHHHHHHHHHH! GRADE! THIRD!" Buster's frame quickly expands to triple his original size, with it all being mostly enormous musculature, which scares almost everyone, including the fighters who had weapons pointed at him.

  "How is he able to use third grade!?" "The Emperor said he was weakened!" The death stalkers all soon stare at their Emperor, who simply vats an eye as he moves his hand around, almost expecting them to keep fighting, which they suddenly start doubting as the first guy who Buster initially grabbed gets his brains blown out by sheer pressure.

  The crowd soon goes ballistic once all the blood from the first guy flies everywhere, with the old folk cheering Buster on as the people who bet on the dead fighter cry out loud not to pay up. "What's wrong? I thought you were going to finish me in two seconds." Buster provokes the younger male into attacking him, which he does.

  "Don't grow too cocky old man! I still have my tricks! Dust warrior! Dust armor! ARMAGEDON!" The younger guy conjures some sort of dust mecha armor, which, apart from looking cool, boosts his power and strenght by multiple factors, almost like the KP engine, with just one minor flaw that the Engine didn't have.

  "Perhaps letting Buster return to the Arena was a mistake, my lord; he is clearly still strong; shouldn't we just keep him jailed?" One of the Emperor's advisors says to the Emperor, who quickly corrects him. "Buster is a beast, an intelligent, useful beast. Why not entertain the people with him for a little while? Besides, he is not leaving the Arena alive, not if he chooses to challenge me, which he will most likely do."

  Meanwhile, in the Arena, the fight between Buster and the two remaining warriors was still a close tie between them as Buster kept repealing almost any attack thrown at him with pure raw strenght. "Open gate! Lemon Squeeze!" The lady finally joins the battle with magic, trying to stay away from Buster as much as she can while the Dust-armored guy gets slowly pummeled by a much stronger Buster.

  'I have to retreat and let him take some heat off with Sandra; he is hurting me quite badly,' The dust armor guy thinks as he slowly starts moving toward the lady who keeps moving around so she doesn't have to directly join the fight forcing the Dust guy to abandon his dust armor after getting a tremendous shakedown.

  "Why aren't you helping me, Sandra!? You know he is beating my ass, right?" The dust fighter angrily shouts at the girl in his team, who only looks like a deer in the headlights, as Buster charges directly at her without regard for her gender or power.

  "Sandra!? SNAP OUT OF IT! Sandra!" Sandra finally turns right at the end, letting the Dust warrior see her fearful eyes in the face of absolute power. Sandra's quick and effective death by Buster makes the entire crowd cheer as her body parts explode everywhere once he hits her with all his might, sending viscera and blood all over the crowd behind her.

  However, even though victory was so close to Buster, his movements suddenly began to seem a bit heavier as his breathing slowed down, clearly showing signs of exhaustion after only a short amount of time, for he was no longer in his prime. Keeping such technique active for so long at his age, along with all of his previous injuries, started to slow him down considerably as his muscle mass gradually decreased to Grade Two.

  {Heavy breathing}

  'That's it! He is old and injured! I just have to evade him long enough for him to run out of stamina, then I'll finish him once he is tired!' The Dust fighter then sets out to play the long game as Buster tries to recover his breath after running around for a while. He is clearly tired and is already going back down all the way to First grade.

  'I was hoping to kill the guy second and the girl last; it seems like my bet failed; I barely have the energy to keep first grade for a couple of minutes more, and then I am completely out.' Buster looks at his opponent and then at the Emperor watching from the podium, which finally motivates him to rush the younger fighter, who chooses to flee, running away from Buster like lightning.

  "BOOOOO!!!" "BOOOOOOO!" "FIGHT YOU COWARD!" "STOP RUNNING AND FIGHT!" "SHAMELESS!" The entire Arena soon turns on the cowardly younger fighter, who doesn't seem to care as he realizes he stands no chance of winning until Buster's out of energy, so he keeps running until it stops working.

  While the Dust warrior ran around in apparent circles, Buster ran around picking up weapons from the dead gladiators, which finally allowed him to start chucking stuff at him, aiming primarily at his torso and legs. {Knife cutting the air} "AHHHHGGG! Son of a bitch! UGGGH!" The Dust warrior falls to the ground as a sharp throwing knife hits him right in the thigh, forcing him to the floor as Buster slowly walks to him.

  "HEY! HEY! You don't have to do this, man! We can end the duel! Just call a vote! Let the Emperor choose if you kill me or not!" The dust fighter, clearly thinking Buster is stupid enough to believe his lies, gets a sudden surprise when Buster mercilessly picks him up from the hair just to stab him with his own sword.

  "I already got betrayed many times by the same trick, kid; bad luck for you; I've seen many like you before; good night." To end the man's suffering, Buster just takes the sword out of the man's abdomen and uses it to chop his head off with a single strike, causing the crowd to cheer at the sight of death and violence.

  However, as everyone cheers, Buster's name on the same guy who has just had a great display of power suddenly stops moving. His heart finally gives up, and he decides to stop working, causing the sudden collapse of the retired fighter. Buster's hand goes directly into his chest as he falls to his knees and accepts death.

  'This is it. This is the way I go; at least I go out with a bang. At least I go out with a victory and not a humiliating defeat. I'll take it at this point. Anabel, wherever you are, continue my journey for me. I've told them nothing about your abilities or if you have access to my technique. I hope you grow to be a healthy, happy woman one day; I would love to see it, but I can't. Goodbye to my disciples. Please continue in the ways of the KP.'

  Without any more sudden movements, Buster's body completely collapses, his eyes turning gray and his body becoming stiff all in an instant, causing the crowd to worry about him as the Emperor laughs. "I told you he wouldn't make it alive, didn't I?"
