"Mumen Rider went in there?!" Bespectacled worker asked as he looked at the console.

Immediately after the aforementioned hero had ended the call Bearded worker tried to reach him again, to hopefully make him realize there was no point to him going as it would only result in his death.

"Yes, I couldn't stop hi-" Bearded worker began to respond only to stop as his call had finally gone through "Hello? Mumen Rider! what's your location?!" He asked as he put a hand to his headset "This is beyond what you can handle, the monster even took out a class S hero! we need to assemble a subjugation squad and fast!" He explained.

There was a small period of silence on both ends of the call afterwards and just as Bearded worker was about to repeat himself a response came, and the voice they heard sent chills down both their spines.

"Tell me where he is, NOW." The voice of Saitama demanded in a tone so serious and even menacing that both men were actually taken aback by it, as they had never heard him speak in such a way.

Though they were of course confused as to why One Punch Man of all heroes was answering Mumen Rider's phone given how he was speaking they knew it would not be wise to say anything other than what he wanted to hear.

"H-He's at the city's evacuation shelter, just south of your position." Bearded worker replied.

Having obtained the information he needed Saitama ended the call leaving the two men to talk among themselves as to what they had just experienced.

"That...was One Punch Man right?" Bearded worker asked as he looked to his associate.

"Yes, but he sounded so void of life and emotion..." He replied.

Laughter filled the space of the evacuation shelter but it came not from the heroes nor of the people instead it came from The Deep Sea King as he now stood over the fallen forms of his foes.

"Ha ha ha ha!" He bellowed as he moved his gaze to the crowd of onlookers "Now, why so quiet all a sudden?" He questioned as his grin returned.

However just as he was about to proceed with slaughtering them all the sound of something beating against the rain caught his attention, as it was coming from outside and was heading his way.

"Hm?" He sounded as he looked over his shoulder through the massive opening he left in the wall.

But before he could see what was coming for him Sea King was struck across the face with multiple slash marks causing him to reel back in pain.

"GAH!" He sounded as he placed a hand to the wounds.

Shocked and stunned by what had just happened the civilians looked above them and found none other than Mutsuko flying in the air with the Sea King's blue blood dripping from her claws.

"That was only the first taste of what I'm going to do to you, YOU BASTARD!" She cried out as with great speed she flew towards him once more.

Readying to deal yet another gruesome wound to her foe just as she was right in front of him he turned to look at her which revealed two things. The first was that in just the few seconds since she had attacked the wounds had healed completely leaving not even a single scar. And as for the second, it was revealed that the Sea King even with most of his tricks and trades having been displayed already he still had one more thing to show, which was he could produce acid from his mouth. Unfortunately this revelation only came as when she was upon him to attack he whilst looking to her spat a ball of the acidic compound directly onto her causing her to stop.

"AAAAAAAAAAAH GOD IT BURNS!" She screamed as with unfounded haste the acid was eating away at her flesh and bones.

Sadly her pain would soon only worsen as the Sea King reached out to grab her and once he held her within his hand he used the other to grab her legs and tear her in two.

"INSOLENT BUG!" He shouted as he threw her upper half across the room and into the wall.

Having but only a little life left in her Mutsuko, even as her entrails and blood began to fall from her torso weakly looked up to Sea King who by using his great speed now stood before her. Feeling anger course through what remained of her form Mutsuko cursed herself beneath her breath at how she wasn't able to avenge her fallen kin and now would soon be joining them. But just as Sea King raised his hand into the air and readied to bring it down atop of her a sudden blast of heat struck him from behind.

"AAAAAAAAAAAARGH!" He screamed in pain as it scorched away his cape and burned his backside "WHAT NOW?!" He questioned as he looked back to the opening.

Standing there within the massive hole in the wall were three humans though the one that caught his eye the most was the one standing in the middle, as he was the one with smoke coming from his hand revealing he was the one who had shot him.

"Mutsuko!" Fubuki called before she clasped a hand over her mouth "Oh my god..." She said shocked that in the few seconds they had been apart so much had been done to her.

Unfortunately for Fubuki and the others they would not have long to react to their injured friend as Sea King growing quite tiresome of these interruptions ran towards them seeking to be rid of them as swiftly as possible. But instead of waiting for him to reach them Genos instead blasted off towards him and with a roundhouse kick clashed with him in the center of the room causing a small shock wave to be sent out as the other blocked it with his arm.

"You're going to pay for this." Genos told him as he increased the thrust power of his leg.

"You humans truly are pests, no matter how many of you I kill more keep coming!" Sea King replied as with a strong movement of his arm he broke their standoff.

Yet instead of Genos following up with another attack the moment he was clear from Sea King Fubuki proceeded to launch debris from the destroyed wall at him, making sure to try and aim each piece so that it might either pierce his flesh or do considerably more damage. Not even so much as phased by the objects being flung at him as he considered them to be nothing but pebbles Sea King with ease swatted and destroyed each object that reached him slowly continuing his approach. But amidst the seemingly endless barrage of debris King took charge towards him hoping he would go unnoticed long enough to close the distance.

"I'm still not that strong, but I have gotten stronger, so maybe I can actually be of some use!" He hoped as the moment he was upon the Sea King he threw a punch forward aimed at the other's gut.

Unfortunately for King while his punch was by no means weak and the Sea King did feel it, it didn't so much as scratch his skin. Thankfully before Sea King could react and attack King Genos flew towards their foe's face and with as much strength as he was able to muster delivered a kick to his cheek which actually managed to send him flying into another wall. Falling to the ground beside him Genos, King, and Fubuki all took a moment to breath all the while hoping that their attack had done at least SOMETHING worthwhile to their opponent. But as the seconds passed soon Sea King rose up from his place in the wall and while his cheek now had a hole in it he still cast them a look which read nothing but pure hatred.

"You insolent little worms." He spat as the wound healed within seconds "YOU ARE GOING TO DIE ON THIS DAY!" He shouted as he charged fourth once more.

Readying themselves for another battle just as Genos like before flew forward to meet their attacker the Sea King suddenly cast one of his toothy grins before looking off to the side. Unsure as to what he was doing the trio felt their eyes widen in shock as he swung his arm towards the crowd of people who during this entire bout had decided to remain and watch instead of flee for their lives. Knowing well he wouldn't be able to attack him AND keep him from hurting the civilians at once Genos decided to leave the offense to the others as he moved to where Sea King's attack would land and catch it with his arms. But alas this was what Sea King planned for as the moment Genos stopped his attack he reeled back his head before spitting out another ball of acid, and because he had put all of his focus on blocking the first attack Genos was unable to dodge this one.

Time then seemed to slow as the acid splashed against his form and while the crowd as well as King and Fubuki had looks of shock adorn their faces Sea King instead had one of satisfaction. Just as it had done to Mutsuko the acid worked horrifically fast resulting in nearly every part of his torso and even some parts of his head to be dissolved. But since he was mostly machine instead of flesh the damage was far worse as after a few seconds his arms fell off and to the floor. Feeling little to nothing as Mutsuko had Genos could do nothing but stand there in horror and agony.

"G-Genos..." Both King and Fubuki muttered completely at a loss for words at how little of their friend remained.

Feeling his present smile slowly turn into his trademark grin Sea King grabbed a hold of Genos's head before tossing him at Mutsuko causing them both to fly out from the building on a slab of the wall itself. Still in a state of shock and horror neither King nor Fubuki were able to react as Sea King ran to them and with one swift kick sent both of them flying out of the building as well and into the rain. Hitting the soaked concrete of the road as hard as one could imagine both of their bodies screamed out in pain to the point where it was near impossible to keep their eyes open. Feeling his satisfaction grow more and more Sea King returned his focus to the terrified people before him holding his arms out as he did.

"Are there any MORE who wish to challenge me?!" He demanded to know not seeking to be caught off guard a third time in a row.

Yet just as before instead of receiving a vocal response Sea King was suddenly lifted into the air for a slight moment before being thrown into the ceiling. Completely stunned as to what was happening he was soon thrust back down to the ground and was now face to face with the one responsible for this strange occurrence.

"You are dead fish breath." Tatsumaki said in a cold and heartless tone the likes of which only a serial killer could rival.

But before Sea King could come up with something to say in reply Tatsumaki threw him once more into the air only this time through the ceiling and into the sky. Following through the hole she had made she proceeded to thrash Sea King about in the air seeming to attack him with just her psionic energy. Grunting and even screaming a small bit as blow after blow was dealt to him, within the time span of just a few seconds he had been struck near a thousand times resulting in countless bruises to adorn his form. Yet even as she continued her assault Tatsumaki began to send him higher and higher into the sky and just as he was nearing the top of the clouds she suddenly sent him downward towards the earth like a meteor.

And because of both the speed and power used to send him downward in addition to his already acquired wounds Sea King was also set aflame as if he were coming down from the atmosphere instead of just the sky.

"Time to die." She stated as she balled her hands into fists.

Just as he was about to make contact with the ground the concrete below suddenly changed into large jagged spikes causing his descent to end with him being impaled. Looking down to his now mangled form Tatsumaki slowly descended towards him crossing her arms as she did.

"Whose the weakling now?" She asked as she reached him.

However as it seemed as though he had finally met his match and was now deceased the moment Tatsumaki was but only a few feet away from him something shot out from his mouth and attached itself to her arm. But before she could react or even see what it was the moment it had made contact it pulled her towards him and with no issue at all Sea King pulled his right arm from the spikes and delivered a punch to her face. Due to his strength which should not even been present given his wounds Tatsumaki flew from him and into the shelter. Completely shocked that she had somehow been taken off guard just as she was about to free herself from the wall and continue to finish him off his hand suddenly wrapped itself around her throat causing her to look towards him.

"Thank you for bringing me back out here to the rain~" He mused as he placed his free hand to his chest "I was starting to shrivel up again but because of you that is no longer a concern." He said as he tightened his grip "So allow me now to show you how much I APPRECIATE IT!" He shouted as he ripped her from the wall and sent her to the ground.

Not allowing her even a second to react Sea King proceeded to unleash a torrent of blows with speed that almost matched the rate in which she had attacked him. Blow for blow for blow he continued to assault her and while after the first few she had tried to erect a psychic barrier to protect herself due to her already somewhat dazed and injured state it didn't last long. So now she was forced to simply lie here and receive this beating unable to stop him from no doubt killing her by the same means.

"JUSTICE CRASH!" A voice suddenly shouted as a bicycle flew through the air and hit the Sea King's backside.

Ceasing in his attack against her Sea King slowly looked over his shoulder to see who had the audacity of interrupting him for the fourth time in a row. And to no surprise standing there with his arms raised in front of him was another human only this one was dressed up in the most amusing attire he had seen from any of them yet.

"This is just getting ridiculous..." Sea King said as he rose to his feet.

Watching as the other rose from the ground Mumen Rider wasting no time at all rushed towards his opponent with a fist reared back and ready to attack. Sadly instead of landing his punch as he had intended he was instead grabbed by the other only to then be thrashed on the ground as if he were a toy of some kind. Unfortunately his humility would only worsen as after but a few seconds of thrashing his costume's sleeve would tear resulting in him flying off to the side. Watching as he landed on the ground a bit of relief came to Sea King as he was able to refocus his attention back to the other human.

"Apologies." He said as he turned back to her "I nearly forgot to kill you." He said as he prepared to continue punching her.

"Justice, TACKLE!" Mumen Rider shouted as he ran back to Sea King and grabbed him by the waist.

Looking down at the human who he was certain had been dealt with Sea King could not keep a look of irritation and disgust from coming to his face as he was forced to send this human away from him once more, this time with a punch. Returned to the ground he had just gotten up from Mumen Rider even as every fiber of his being told him to stay down did his best to prop himself up on his forearms to hopefully then get back to his feet.

"No one expects much...not from me..." He began as blood started to fall from his head and to the ground "They think a class C hero won't be much help...I know that better than anyone!" He grunted as he continued in his effort to stand "I'm too weak for class B...I'm not good enough...I know that much..." He went on as he got to his knees "I'm aware I have no chance of beating you...no one needs to tell me...ANYTHING LIKE THAT!" He shouted in frustration.

"What're you babbling on and on about? BEGGING for you life?" Sea King asked as he stared down at the other.

"And yet...I must try...It's not about winning or losing, It's about me taking you on right here and right now!" Mumen Rider shouted as he got to his feet and even managed to take a few steps forward.

Feeling tears come to their eyes the residents of City J who still watched on from inside the shelter were moved and touched by the words of their hero. But they were not the only ones who heard his emotional cry for Fubuki, King, Genos, and even Tatsumaki who were still somewhat conscious also felt inspired, causing them to try their hardest to get back to their feet but to no avail.

"Enough of your rambling, time to finish you off!" Sea King declared as this human for some reason seemed to be the most persistent one as of yet.

Upon gaining the other's full attention once again Mumen Rider readied himself as best he could in his state for another attack, though given his injuries he more than likely would fall at any second.

"You can do it!" The voice of a young boy called from the shelter gaining his attention "Mumen Rider, you can do it! you're the cyclist of the justice, you can beat him!" The boy cheered on in support.

And it seemed as though this boy's cry was but only a spark as after his cheer had been spoken the other citizens began to cheer as well.

"He's right, get him!" "Yeah do it!" "We're all counting on you Mumen Rider!" Were but a few that could be made out from the thunderous shouts that came from the crowd.

Feeling a sudden surge of strength and will wash over him just as the rain was Mumen Rider reared back his fists once more letting out a warrior's yell as he did before he took off towards the other ready to give it his all. And if this were some sort of fable or children's book the encounter would have ended with him being the victor, but this is not some story written with a good ending in mind as in reality he made it not even a foot's distance to Sea King before he was sent flying for a third time by an uppercut. For the second time time itself seemed to slow as the last hope the people had to be saved sailed through the air and towards the ground just like the others. Yet as he continued to fall towards the ground and everyone expected to see him land harshly he instead was caught before that could happened by the one person none of them were expecting.

"Nice fight man, you should be proud." Saitama told him with a small smile before he began to set him down to the ground as gently as he could.

Watching in silence as he set Mumen Rider to the ground it was only a second or so more before they all erupted in another cheer though this one was much more joyous and ecstatic.

"OH HELL YEAH IT'S ONE PUNCH MAN!" "OF COURSE HE WOULD COME TO SAVE US!" "YOU BETTER BE GOOD AT KISSING ASS FISH MAN!" Were just a few of the things they began to say as all fear and worry left their being.

But before they could say even more things in either celebration or to taunt Sea King once Saitama was certain Mumen Rider would be fine without his attention he stood back up and looked towards Sea King. And what both Sea King as well as the crowd saw caused them all to look to him with stunned expressions.

"H-Holy shit..." Was the only thing to be said from the crowd this time around and by one person nonetheless as instead of seeing the normally relaxed and carefree expression of their hero they instead saw a look so intense and so absent of any kind of emotion that even the devil himself would be shaking in fear.

"You." Saitama spoke as he had his gaze focus solely on Sea King "Where. Is. Kaemon?" He asked.

Unsure as to who he was referring to after giving it a bit of thought Sea King figured there could only be ONE person he was referring to, which caused him to grin.

"Oh, you mean the worthless little wad of kelp?" He questioned as he removed his crown from his head "Here, why don't you see for yourself?" He asked as he reached in and pulled something out.

Feeling his eyes widen as well as his hands balling as tightly as they could into fists a part of Saitama was trying it's best convince him he was not seeing what was right before him. But no matter how much he wanted to deny it nor how badly he wanted it to be a lie due to the few drops of blue blood that fell from the neck there was no mistaking that the severed head of Kaemon that Sea King held in his grasp was in fact real.

"I can't BELIEVE you actually gave this worthless excuse for a sea folk a name." Sea King admitted as he held it up to his face "I mean the only thing it was even good for was being a source of food to the rest of us~" He mused with a slight laugh.

.

.

Silence, that was what took hold of the air for the moment Sea King's cackling reached Saitama's ears, he rushed forward and delivered an uppercut like none had ever seen before. First there was the shock wave the punch created which was so powerful it began to tear Sea King's flesh from the muscle before the punch itself even connected. Then once the punch had landed Sea King in an almost stop motion like fashion lost his muscles, his organs, and then his bones very similar to how a piece of paper would burn in a fire. Finally there was the shock wave once again that continued to go upward until it reached the sky where upon doing so it cleared out the clouds for seemingly hundreds of miles around bringing back both the sun and a clear blue sky.

As for Kaemon's head however luckily it hadn't been hit by the punch and instead of being destroyed it was dropped to the ground once Sea King's body had been dealt away with. But as a few seconds past by and no sound was heard at all Saitama knelt down as to pick up Kaemon's head where he made a discovery which made him sick to his stomach. Frozen on Kaemon's face was a look of utter horror an anguish meaning that they had little to no time to react before Sea King killed them. And while the very sight alone of Kaemon's severed head was enough to ignite the emotions Saitama rarely ever felt it was this expression that did the unthinkable.

For the first time anyone could ever recall Saitama shed a tear which rolled down his face before landing on his glove.
