Ghost Town of City Z, mere moments after Setsuka defeated Mosquito Girl

Atop the roof of one of the abandoned buildings near the place where Mosquito Girl was easily defeated, a certain female Subterranean continued to look at the place where Setsuka effortlessly defeated the mosquito-human hybrid for a few seconds longer.

'It seems that I made the right decision by avoiding a direct confrontation with the surface dweller until l have gathered sufficient information on her, even if her confrontation with the flying monster was brief. It is safe to assume that she would emerge victorious against us even if all of us were to simultaneously attack her. I must head back home and warn the others about her true strength before that metal man notices me.' the female Subterranean on the scene said before deciding to make her way back to her home under the abandoned area of City Z.

"New target acquired!" the blonde cyborg loudly shouted out as he proceeded to blast a beam of fire at the Subterranean with the ninja attire.

'It appears that I have to deal with the mechanical human after all. It should be an easy task to accomplish for me.' the Subterranean with the ninja attire thought to herself as soon as she dodged the attack of her opponent.

"It looks like I have managed to find another dangerous monster lurking in this area." Genos said as he glared at the female monster standing in front of him as he raised an arm in her direction.

"I would prefer it if you were to address me as Tikal." the female Subterranean with the ninja attire said as she continued to look at the young cyborg standing in front of her.

"I will not bother to call you with a name monster." Genos stated to his foe as the palm of his raised hand along with his eyes began to glow a bright yellow.

'Hmm…Your eyes must really allow you to see things that no living thing would normally be able to see. That will be a bit troublesome to deal with if I were not a trained ninja. I will just have to cut you up as soon as possible.' Tikal thought to herself as she sized up her opponent once more.

"Inciner-!"

Slice! Slice! Slice!*

But before the blond cyborg could even say his attack, Tikal was able to quickly decapitate his head while also cutting right through his abdomen with a horizontal and diagonal slash of her swords before she leapt away from the cyborg.

And moments after Tikal had cut him up, the young cyborg's body exploded.

Tikal sheathed her katana before she began to quickly jump from one roof to the other as she made her way to her home.

Meanwhile, somewhere further away from the Ghost Town of City Z

Inside a dimly lit laboratory, an elderly man with a bowl cut was working on a pair of robotic limbs with great concentration.

'I believe that these upgrades will be extremely helpful for Genos once I finish making a few adjustments to these prosthetic limbs.' Doctor Kuseno thought to himself as he continued to work on the arm that he planned to adjust for the blond cyborg the next time he came in for his repairs.

City W, 1405th day after Setsuka's training began

In the streets of City W, there was a number of black portals began to appear throughout the city.

"Aaaahhh!"

"Somebody help me!"

"Where did these things come from?"

The sounds of people screaming and panicking was all that could be heard as the portals continued to swallow everything within their vicinity.

And as the portals continued to open up, a tiny naked monster emerged from the mysterious black portal. She was as tall as a toddler with bright pink skin, with a feminine humanoid body and a face that would look no different from that of a human's were it not for the second pair of eyes that could be seen on her forehead.

A sinister grin on her face could be seen on her face as she floated above the people of City W that were running away from the black portals that had suddenly appeared out of nowhere.

"Ahahahahaha! Die you filthy insects!" the pink monster manically cackled as she looked on at the destruction that her powers were causing throughout the part of the city that she was flying over.

"Warning. A mysterious monster has appeared in City W. The monster is able to create black portals that will swallow anything that may still be under them. Please evacuate the area immediately. The threat level of te monster has updated to Threat level: Dragon." a voice from one of the speakers that was installed in this area of the city announced.

Within two minutes of her arrival, there was a scene of mass destruction happening before the eyes of the remaining residents of this part of the city. A number of buildings in the city had been partially submerged into the ground where they once stood and they continued to sink into the portals that had been formed under them.

And as the pink flying monster continued her destructive activities, two people who were standing atop one of the buildings that Vacuum Woman had yet to destroy a few meters further from the spot she was flying above.

"Are you ready to blast that tiny monster to smithereens?" a man wearing a soldier's uniform said as he aimed a bazooka that was resting on one of his shoulders right at the flying monster.

"You're damn right I am! But don't forget that we're gonna have to hit it a couple more times." the other soldier standing on top of one of the buildings said as he also aimed his bazooka at the flying monster.

"Yeah!" the first soldier agreed with his fellow soldier.

"Ahahaha! Perish before my awesome powers puny humans! For I, Vacuum Woman shall destroy all you like the insects that you are!" the tiny monster shouted out with a high-pitched voice.

Boom!* *Boom!*

Vacuum Woman was suddenly bombarded by two men carrying bazookas who were currently perched on the roof of one of the buildings that had not sank into the ground.

"Yes! We landed a direct hit against that damn flying monster! And we did it all before any hero could be dispatched!" one of the men carrying a bazooka rejoiced as he saw their target get hit by the shot that he fired.

"Calm down man. We can't celebrate just yet. We still haven't seen the body of the monster. Let's wait for the smoke to clear up before we go and say something like that." the soldier next to him said as he already began to insert another warhead into th bazooka.

"You really think that the monster could- Whaaaaat? How is she still alive?" the first soldier exclaimed in shock when he saw the pink monster unscathed once the smoke in front of them had dispersed.

"Foolish humans, it is futile for you to try and harm me. For as you can see, I am capable of taking your hits without suffering any damage. Now die." Vacuum Woman declared as she quickly opened a black portal right under the feet of the two soldiers, and they were quickly absorbed into the portal before they could even register that there was a portal under them.

Inside the Hero Association branch located in City W

"How is it able to take a hit from a bazooka and still survive? What is its skin made of?" an employee of the Hero Association who had brown chin-length hair that was cut in a buzz cut asked in a panicked voice as he saw the footage on the large monitor of the office room when it showed Vacuum Woman casually shrugging of the bazooka blast before the footage was cut off.

"Stop panicking and tell me if there are any heroes in the area! And can someone please contact the S-Class heroes? It looks like we'll need their help this time around!" a bald middle-aged man who happened to be the head of the Hero Association located in City W office shouted out to the other employees in the large office as he observed the scene unfolding from the feed that the drone they had sent at the scene was providing them.

"We've got confirmation that five heroes are already heading that way as we speak sir. Golden Ball, Chain'n'toad, Heavy Kong, Magic Trick Man, and Wild Horn have responded to our call for help. But we weren't able to get a response from any S-Class heroes sir." another employee with his chestnut hair cut in a bowl cut gave his report.

"I guess that will have to do for now, but please make sure that you keep calling for the S-Class heroes as well. I have a feeling that it may take more than one S-Class hero to defeat this monster." the head of the City W branch of the Hero Association ordered the employee who had styled his hair in a bowl cut.

"Yes sir!" the employee with the bowl cut hair accepted the orders of his boss before making his way towards his desk.

"Sir, the analyst team have made a request to update the threat level of the monster! They have stated that the portals it is creating have the potential to destroy multiple cities." a female emolpyee with chin-length blue hair informed her boss.

"Tell them to announce the change in the monster's threat level immediately!" the bald man commanded the blue-haired employee, who simply nodded before promptly taking her leave.

"Well, I hope that they will be able to hold off the monster until we're able to get a response from an S-Class Hero." the bald man muttered to himself as he continued to watch the scene of destruction that was playing out on the monitor in front of him.

Back at the downtown area of City W

"This is a warning to all citizens of City W. A monster of threat level 'Dragon' has appeared within the city. Please evacuate from the city immediately. I repeat, please evacuate from the downtown area immediately." a speaker began to shout out loud as the destruction throughout the city continued to unfold.

And as the flying pink monster continued to demolish all the buildings in the area, five people could be seen rushing towards the flying monster in front of them.

One of them was a muscular bald man with a tattoo around the right side of his face, a black beard minus the moustache and a pair of earrings. He was wearing a green piece of clothing around his from his left shoulder and a chain around his right shoulder and a belt around his waist that had the words 'KONG' written on it.

The other person present was a man with a goatee cut in the shape of three hills wearing a beanie covering his head, a Letterman jacket with red outlines and jeans sucking on a lollipop. He was carrying what looked to be a custom-made slingshot on one of his hands and a bunch of marbles in his other hand.

The one in the center of the group was a young man with dark hair wearing a magician's outfit consisting of a top hat with a question mark appearing at the center of the hat, a suit and a cape that was draped over the suit and a mask that covered the upper half of his eyes.

The one next to the magician was a man with a mostly purple body suit with bits of gold and white throughout parts of the body suit, shoulder pads of the same colour, a belt with the letter 'W' coloured in gold at the center of it, and a helmet that had a pair of horns on the sides of the head. He had a small drill-like mechanism attached on the right side of his arm.

And the final person of the group was a man with a red frog mask with the lower half of the mask being white in colour covering his face. He was wearing a white karate gi with a black belt tied around his waist while also carrying a kusarigama around his waist.

"We must hurry and stop this anomaly of a monster before it causes any more damage to the city by any means necessary." Wild Horn said as they continued to approach the tiny pink monster.

"Yeah. It's shocking that such a tiny monster can cause so much damage. But are we sure that we can take on such a powerful monster?"Chain'n'toad asked his fellow heroes as they were now right behind the flying monster.

"I feel you man, it really sucks that we may not beat such a strong monster. But at least we can distract the monster until a bunch of S-Class heroes arrives on the scene." Golden Ball said while placing his marble with his custom-made slingshot. After properly aiming at the back of the monster's head, he shot his bullet towards his target, hitting it right at the back of it's head.

Unfortunately for the hero with the slingshot, the monster did not suffer any damage from the marble ball that had hit her.

"What? How did my memory shaped bullet not injure the monster just now?" Golden Ball shouted out in shock while looking at the unharmed flying monster in front of them.

But before the other heroes on the scene could even make their moves, the flying monster vanished from where she was floating earlier and proceeded to knock out all of the heroes that had been following her.

'Did these foolish insects think that they could catch me off guard? Ha! I knew they were following me before they even got close to me thanks to my good hearing abilities.' the pink monster thought to herself as she looked over the unconscious bodies of the heroes that had intended to defeat her. She then began to prepare a portal under the five heroes that had failed to attack her.

"Pyro Canon Beam!"

But before Vacuum Woman was able to actually open a portal under the unconscious heroes, she was hit by a concentrated energy beam straight to the face.

When she looked around for the one who had attacked her, she was met by the sight of a cyborg who had shoulder-length black hair wearing a pair of orange tinted goggles on top of her head as her right arm was stretched out in front of her taking on the shape of a mini railgun.

The cyborg's was wearing a red jacket along with a black tanktop and black jeans and dark brown cargo boots.

"It seems that I was not able to defeat you with such an attack." the black-haired cyborg stated with a monotone voice while looking at the unscathed monster above her.

"So another insect has come to try and stop me from destroying the other humans as I please. Well then, prepare to meet a gruesome face for shooting my adorable face point blank and trying to stop me from killing these other worms." Vacuum Woman said with a grim expression on her face.

The cyborg did not response to the words of Vacuum Woman and simply leapt towards her, intending to attack her close up.

Vacuum Woman simply extended her arm in front of her and opened a portal in front of her in order to suck up the cyborg that had leapt towards her.

But the cyborg was able to move himself to the side and approached her from the side. But as he prepared to punch the monster in front of him, she simply grabbed her arm and pulled it off of the female cyborg before punching her right in the face.

"Ugh!" the cyborg grunted as she was sent flying to one of the buildings that was still intact and making a crater at the wall of the building the moment she made impact with it.

"Pathetic. You aren't much different from those other insects that tried to attack me earlier." Vacuum Woman said as she flew towards the cyborg she had just sent flying.

"Do not think that I am done just yet, monster!" the cyborg said as she wobbled and began to stand to her feet from the room behind the wall he had crashed into.

"Hah! You can't even stand properly and you still think that you have a chance of defeating me? Foolish insect, I shall split you in half with my portals!" Vacuum Woman said as she made a portal right under the leg of the cyborg and began to sink her target into the portal until her lower waist was completely submerged within the portal.

"Yo! I would suggest that you stop doing what you are doing before I come over and stop you myself."

But before she could cut the black-haired cyborg, she was threatened by a feminine voice that was coming from behind her.

Curious to find out the identity of the person who would dare to threaten her so casually, Vacuum Woman turned around only to see a young bald woman wearing a yellow jumpsuit with red gloves and boots along with a white cape draped over her shoulders looking straight at her.

'What is someone like her doing here?' Vacuum Woman thought to herself the moment she saw the bald woman in front of her.

'Is this woman crazy?' the cyborg thought to herself as she observed the bald woman that was standing in front of her.

But as soon as Vacuum Woman's face was visible to the bald-headed woman, her blank expression was replace with a look of someone who just saw the cutest thing in the world right in front of her.

But as soon as Vacuum Woman's face was visible to the bald-headed woman, her blank expression was replace with a look of someone who just saw the cutest thing in the world right in front of her.

"Oh my gosh! Aren't you just the cutest little thing! I just want to hug you and squeeze you forever and ever!" the woman standing below her giddily shouted as she quickly made her way towards the pink monster standing in front of her before she proceeded to tightly hug her.

"Huh? Do you think that I would want to be cuddled by an inferior insect like you? Let go of me you damn vermin!" Vacuum Woman angrily shouted back at the human who had called her cute as they fell to the ground below them.

"Wow, you're even cute when you get angry!" Setsuka said with great excitement, completely unfazed by the insult that Vacuum Woman had thrown her way as she continued hugging the pink monster tightly.

"I'm telling you to stop touching me you inferior insect! Let go of me before I kill you!" Vacuum Woman yelled at Setsuka as she struggled to free herself from the bald woman's embrace.

"Nope! You're just too adorable for me to let you go." Setsuka said as she continued to hug the pink monster in her arms.

'Why am I struggling to release myself from the hug of this annoying bug! I should be capable of destroying buildings with my bare hands, but I can't even budge from this vermin's grip on me!' Vacuum Woman thought to herself while she continued to struggle to free herself from the hug of the bald woman.

'Hmm, it's as if I'm hugging a pillow right now.' Setsuka said as she continued to hug the tiny monster in her arms.

"Take this you stupid insect!" Vacuum Woman shouted out as she landed a punch right towards Setsuka's right cheek.

Pow!*

"OW! Why am I suddenly feeling so much pain? How are you unhurt?" Vacuum Woman shouted out as she held her right hand with a pained expression on her face.

'How is this woman able to shrug off a punch from this monster with such ease?' the female cyborg thought to herself as she witnessed the bald woman hugging the monster that was about to kill her just moments ago.

"Wow, your punch is pretty impressive if you ask me. I managed to feel a bit of a sting when you punched me just now. I think I'll be going home now." Setsuka simply said as she made continued to hug Vacuum Woman tightly.

And while she was completely absorbed in her cuddle session with the monster, the young cyborg began to crawl towards the bald woman with awe in her eyes.

"Excuse me ma'am, but what is your name?" the black-haired cyborg said as he was close enough to make his presence known to her.

"Hmm?" Setsuka said as she stopped her cuddle session with Vacuum Woman while looking left and right for the person who was asking for her name.

"I am below your feet, ma'am." the cyborg simply said.

And as she looked down to her feet, she saw the young cyborg looking up at her with hopeful eyes.

"Oh? I didn't notice that there was saving a beautiful babe like you from this adorable monster." the bald woman said as she finally took notice of the cyborg.

"Please let me become your disciple starting today!" the cyborg begged the woman who was standing in front of her.

"Huh?" was all Setsuka could say in response to the cyborg's sudden request, not expecting to hear such a question from the cyborg who currently lay below her feet.

"I wish to be as powerful as you are someday so that I can beat a powerful opponent like the one in your arms. I was not able to defeat the monster that you are currently holding in your arms, but here you are effortlessly holding the monster with such ease. If I were to become your disciple, I will be a strong…" the young cyborg began to state his reasons before he was interrupted by the bald woman putting her index finger on her mouth.

Vacuum Woman of course was still struggling to free herself from her captor, even if she was now being hugged with only one of Setsuka's arms.

"I appreciate that you think highly of my strength, but I'm not looking to have a disciple under me so you should stop asking to be my disciple, ok?" Setsuka bluntly told the cyborg before focusing her attention to the monster in her arm. The young cyborg simply looked at the woman with a dejected look.

"Hey, is it possible for you to summon her legs back?" the bald hero-for-fun asked the monster in her arms.

"No. I am the only one that can use my portals to travel wherever I desire. Any other living being or item that has been absorbed into my portals will never see the light of day." Vacuum Woman answered Setsuka's question.

"Well, I could at least take you back with me until we can contact someone who can fix you up. There is someone that can fix you up right?" Setsuka asked the young cyborg below her feet.

"Yes ma'am." the black-haired cyborg said with a dejected expression plastered on her face.

"And please don't call me ma'am. It makes me sound like I'm an old lady." Setsuka said as she carried the cyborg with her free arm before she began to walk in the direction of City Z.
