Chapter 147 Bringing Up Old Matters Again


Edited by: Kanaa-senpai


 The ones who finally stepped up to end the lives of the three yokai were Hamazaki Reina, Obata Yui, and Shinohara Misaki.


 The abilities of these three leaned heavily toward support, meaning they rarely had the chance to see blood in direct combat.


 This was the perfect opportunity for them to take that crucial first step.


 Looking down at the three yokai slumping on the ground and incessantly begging for mercy, the three girls did not hesitate for long.


 Mana¹ condensed in their palms as they aimed straight at the fragile, exposed necks.


 With a gentle wave of their slender hands, blood splattered violently across the floor, and the world finally fell silent.


 ”Wow… that was way less of a psychological burden than I thought it’d be…”


 ”Me too.”


 ”It’s probably because we saw how hideous and monstrous those yokai looked before. It doesn’t even feel like we’re killing actual humans…”


 Listening to the girls’ murmurs, Aki nodded with thorough satisfaction.


 Generally speaking, this combat performance deserved an excellent evaluation.


 Setting the matter of raw combat experience aside—since that would naturally accumulate after a few more encounters—the girls’ tactical awareness, cooperation, and mental fortitude had given him a pleasant little surprise.


 Aki had never expected them to become peerless powerhouses or cold-blooded killers overnight.


 He simply wanted them to be able to harden their hearts and completely root out the threat whenever they faced enemies, especially types like the blond punks or NTR thugs.


 After this battle, he could confidently leave them to handle certain complications on their own, giving him much more faith in the overall operations of his organization.


 Controlling his signature azure-blue flames, Aki began to clean up the battlefield.


 Except for the three explicitly executed yokai, the bodyguards scattered across the floor were no exception to the purge; every single one was incinerated until not a single trace of ash remained.


 ”Alright, now only you are left.”


 Aki clapped his hands clear of ash and turned his gaze toward the blond youth standing frozen on the spot.


 Watching Aki—whose aura and demeanor had completely transformed—slowly close the distance, Miura Akira scrambled back in sheer panic.


 His knees buckled beneath him, causing him to collapse flat on his ass.


 ”You… you actually dared to kill Lord Nue and the others…”


 He desperately dragged himself backward against the pavement, his voice trembling with false bravado.


 ”Lord Dragon will never let you get away with this! You’re going to die an absolutely miserable death!”


 ”Instead of worrying about me, you should probably worry about your own skin.”


 Aki didn’t harbor a single shred of goodwill toward that hybrid freak, who was a bastard mix of God knows whether it was a snake or a lizard.


 The creature hadn’t even touched the threshold of becoming a true flood dragon, yet it had the audacity to style itself a dragon; it was truly the height of shamelessness.


 ”My old man is Miura Kazuya, the president of the Miura Corporation! And I am the adopted son of the patriarch of the Mitakai Yakuza! Do you honestly dare to touch me?!”


 Miura Akira was so terrified he was on the verge of pissing his pants.


 Yet, the moment his eyes locked onto Aki’s face, an inexplicable surge of unbridled rage and deep-seated hatred erupted within the blond youth’s heart.


 The pleas for mercy that had traveled to the tip of his tongue instantly twisted back into venomous threats.


 Gazing down at Miura Akira’s completely vacant, delusional eyes and the jarring contradiction between his sheer terror and arrogant words, Aki simply extended his index finger.


 A beam of deep-blue light instantly pierced straight through the center of the boy’s skull.


 Spreading outward from the hollow puncture in his forehead, the azure flames gradually consumed his flesh.


 Within a mere ten seconds, the person Miura Akira completely vanished from the face of this earth.


 ”Calculating the time, their reinforcements should be arriving right about now.”


 Aki scanned the perimeter, and after confirming that nothing had been overlooked, he dissolved the localized barrier.


 The town street remained completely peaceful and serene, looking exactly as if nothing out of the ordinary had transpired.


 Only the slightly torn-up pavement and the cluster of abandoned luxury cars stood as silent testaments that Miura Akira had indeed brought an enforcement squad here.


 After waiting for a short while without any of the remaining supernatural entities actively delivering themselves to his doorstep, Aki decided he would have to hunt them down himself.


 Before departing, he placed a quick call to Himejima Akeno, debriefing her on the situation that had occurred and the clean-up that would immediately be required.


 He instructed her to notify the logistical clean-up crew to handle the aftermath in a timely manner.


 In truth, there wasn’t a massive amount of physical evidence to process; it was mostly a matter of assigning people to drive the abandoned vehicles away and then sending personnel to take over the management of the Miura Corporation.


 He wanted to prevent the company from spiraling into operational chaos, which would cause the ordinary working-class employees to lose their livelihoods.


 Oh, and then there was the Mitakai Yakuza; they would also need to dispatch men to systematically seize their various illicit businesses and territories.


 The Mitakai Yakuza, who were deeply entwined with the Miura Corporation, were similarly devoid of any redeeming qualities.


 Given how incredibly close the two factions were, Aki thought it over for a brief moment and decided it would be best to pull the Mitakai Yakuza up by the roots along with the corporation.


 Compared to dismantling a legitimate corporate entity like the Miura Corporation, dealing with a criminal syndicate like the Mitakai Yakuza was significantly simpler.


 Uncontrolled turf wars and internal restructuring within the yakuza were everyday occurrences.


 A rising syndicate crushing an established family, subsequently absorbing their territory and manpower, was an entirely commonplace matter that wouldn’t raise any civilian eyebrows.


 The process of pulling up these roots went far smoother than Aki had initially anticipated.


 He had originally assumed their delayed reinforcement was because they had caught wind of the danger, or were stationed too far away to make it back in time.


 As it turned out, when he tracked them down to their stronghold, he discovered the remaining A-rank Great Yokai and another B-rank yokai were completely entangled together.


 Aki stood aside and watched the spectacle for a brief moment, silently admitting that this female yokai’s figure was genuinely spectacular.


 He wasn’t entirely certain if she possessed the bloodline of a fox spirit, but she displayed an absolute abundance of seductive, wild charm in bed.


 It was no wonder this self-proclaimed ‘Lord Dragon’ hadn’t deserted his pleasures to answer his underling’s desperate cries for backup; he was entirely too busy hammering away diligently in the bedroom.


 To be fair, one couldn’t entirely blame this ‘Lord Dragon’ either.


 When the man with the gold-rimmed glasses had initially called to notify him, his report had been incredibly vague and muddled.


 After all, at that exact moment, Baku had never imagined his trio would be completely powerless to fight back, let alone that they wouldn’t even be able to flee after activating their Berserk states.


 Consequently, he had only managed to gasp over the phone that they had run into some unexpected trouble against an enemy with superior numbers and momentum, mentioning an individual whose exact strength was unclear but estimated to be an A-rank existence…


 After watching the display for a few moments longer, Aki realized the two had absolutely no intention of stopping anytime soon.


 He decided to act directly, sending this pair of illicit lovebirds straight to the next world right at the absolute peak of their ecstasy.


 Up until the very moment their life force was snuffed out, this toxic pair—who had brought ruin to countless innocent people—never even noticed Aki’s presence in the room.


 With all of the supernatural combatants belonging to the Miura Corporation officially dealt with, the next step on the list was the thoroughly rotten upper management level.


 The very first person to bear the brunt of this purge was Miura Kazuya.


 Compared to his pathetic son, this man possessed fewer of those stereotypical blond-punk attributes, but during the rapid rise of the Miura Corporation, the sheer volume of illegal and heinous crimes he had personally committed was staggering.


* * *


 Three hours later, with a dull, echoing thud, the azure flames incinerated the final target into absolute nothingness.


 Aki rolled his stiff shoulders and let out a long, slow stretch.


 Compared to this kind of repetitive, mind-numbing clean-up work, he would vastly prefer to test his mettle against a genuinely powerful combatant.


 It proved that training Hamamazaki Reina and the rest of the girls while systematically building up his own organization was an absolute necessity; in the future, whenever these kinds of tedious matters arose, he could simply leave them to resolve it on their own terms.


 Including the assets from the Mitakai Yakuza, a grand total of two A-rank transcendent individuals and nine B-rank transcendent individuals—the vast majority of whom were monstrous yokai—were dead, leaving behind not a single corpse.


 The entire executive tier of both the Miura Corporation and the Mitakai Yakuza had been liquidated by Aki’s hand.


 This included the absolute scumbag of a manager who had previously harassed Takamine’s mother, bringing the final body count to exactly fifty-three people.


 This sweeping operation marked the very first time since Aki had arrived in this world that he had unleashed a genuine, uninhibited killing spree.


 Fortunately, because he had taken the precaution of coordinating with the proper channels beforehand, the incident failed to stir up any significant public controversy, though it did mean he now owed Rias another massive personal favor.


 Even with a legitimate nominal justification on paper, generating a disturbance of this magnitude meant that the political pressure Rias’s faction had to absorb on her side was by no means small.


 With everything finally brought to a definitive close, Aki felt a profound weight lift from his chest.


 The persistent, gnawing sense of unease that had plagued him for days on end completely dissipated; it appeared the ‘ultimate move’ the world’s Bitter Parent Template had been holding back for so long had been thoroughly and utterly dismantled by him.


* * *


 It was now the beginning of February.


 More than two weeks had slipped by since he had successfully resolved the catastrophic ‘tribulation’ engineered by the Bitter Parent Template, and Aki’s brief stint of peaceful living was abruptly shattered once more.


 Evidently realizing that holding back a massive, world-ending plot device was entirely futile, the Bitter Parent Template simply reverted to its obnoxious, baseline behavior.


 From time to time, gorgeous girls would randomly attempt to throw themselves at him out of nowhere, and naturally, an endless supply of local blond punks would consistently show up at his doorstep to manufacture trouble.


 These low-tier blond punks were rarely guilty of truly monstrous, capital crimes.


 At the absolute worst, their misdeeds amounted to extorting lunch money from their classmates or using petty leverage to threaten vulnerable girls into doing explicit, shameful things.


 Aki couldn’t exactly go around murdering every single low-life he crossed paths with on the street.


 At most, he would beat them within an inch of their miserable lives or utilize high-level Mental magic³ to completely rewrite their psyche, ensuring they suffered total and absolute social execution.


 While the actual threat level they posed to him was virtually nonexistent, the sheer regularity of it genuinely disgusted Aki to his absolute limit.


 However, it was precisely this incredibly irritating situation that served to remind him of the grand, ambitious vow he had proudly established back when his unique abilities had first awakened.


 He had promised himself that he would claim every single beautiful woman he recognized inside Kuoh Academy, as well as any other location he happened to visit, and firmly tuck them away into his personal collection.


 Whether they were the leading heroines of explicit adult works, mainstream anime icons, or even just minor supporting characters—as long as he retained a clear memory of them from his past life, he intended to take them all down.


 When he had first formulated this grand design, it had been primarily motivated by a desire to farm and acquire as many powerful Talents as humanly possible.


 Bringing up this old matter once again today, however, was done purely out of a desire to aggressively strike back against the annoying mechanics of the Bitter Parent Template.


 Aki had never been a particularly magnanimous or large-minded individual.


 Since the cosmic template insisted on using these trashy tropes to disgust him, he would simply go out of his way to intercept and rescue every single young girl who had either already fallen victim to, or was currently on the verge of being successfully defiled by, these blond punks.


 After all, even if he chose to sit idly by and do absolutely nothing, an endless stream of these stereotypical thugs would still beat a path to his door every single day regardless.


 The moment the thought crystallized in his mind, he resolved to put it into immediate action.


 Using Kuoh Academy as his absolute epicenter, Aki intended to continuously expand his reach outward into the surrounding districts, systematically purging the entirety of Tokyo in one clean sweep.


 He had no intention of letting a single familiar female character slip through his fingers, and by the exact same token, he had absolutely no intention of sparing a single blond punk standing beside them.
