Chapter 15 (Heroic Entrance)

After the relinquish of the makeshift king and the fall of the fake government

Hanje and Moblit came to inform Levi and his team with some awesome news.

"And there you have it. The coup d'etat was successful. Premier Zachary has control of the capital and administrative district. For the time being, the nobility hasn't rebelled." She explained while everyone had surrounded Levi to read the news paper.

"What about the Boss Reeves incident?" Armin asked, the Section Commander reply with a smirk.

"We got a confession that prove the changes unfounded. His son Flegel really pulled through big time."

With Flegel

Flegel pushed a middle age man against a wall, it's the man who create and edit the news paper.

"Don't you get it?!" Flegel didn't finished "The government doesn't give a shit about saving any of us! Face the truth now, because it'll be too late when you're dead!" Flegel replied to the man threateningly.

"That's right! If titans attack us again, there'll be nothing left this time! Not the company! Not our families! Let's print the truth before that happens!" A younger man with glasses stated to the old man, who now had widen eyes, they start printing news papers.

Back with Hanje and the others

"Just like it's written right there. It shows the charges were bogus, they abused their power, and that King Fritz was a total fake. All our actions were justified self-defense. In other words, we're free people now."

Hanje declared, making everyone to cheer and scream loud, excluding Levi who was reading the paper, they all cheered as one. "Woohoo!"

Levi answered to Hanje with a slightly amazement expression.

"Looks like the gamble paid off."

"Yeah. It wasn't just Erwin though. The lone choices of many managed to change the world." Hanje retorted and shook her irises left to see her short Friend taking a step next to her.

"And I managed to kill the three people you loaned me. I'm sorry." Levi apologized to her and resume the discussion. "The thing is, part of the interior Police, their leader, Eren and Historia are somewhere else. If we don't find them soon..." Hanje cut the Captain to inform them about that too.

"Saitama won't let anyone hurt them. Keep faith in our hero Levi. Plus I may have a clue about to where they are, including our bald comrade." She showed them a black book and finished the conversation by saying determined. "Let's get there and put an end to this battle."

As a result of Erwin's actions, it was declared that the current regime would be ousted. That announcement came immediately after the military gained control of the capital and administrative dinstrict. And took place upon the gallows constructed specifically for him. As for Saitama he's still with Eren and Historia, our hero doesn't feel threated, doesn't matter if he'll meet new enemies among the way to help humanity of this world, to get rid of the titans and the bad guys.

Night time

Hanje and Moblit joined forces and took off with Levi and his squad on a carriage, Jean and Moblit were lighting the way on their horses, with torches in theirs hands.

"Hanje. You might know where they are?" Mikasa asked and face Hanje.

"Yeah, I'll explain." Hanje remarked, clearing her throat, she begun.

"Erwin gave me this Scout investigation report regarding Lord Reiss' land. Most of it has to do with an incident five years ago that shook up the Reiss family." Armin's irises shifted to Hanje. "Five years ago?"

"Right. On the day Wall Maria was breached. The day we didn't had such allie as Saitama. I'll summarize the important bits from the beginning." Hanje replied and blink her eyes, she continued.

"As the lord of his territory, popular opinion of Rod Reiss wasn't all that bad. He had five children, and his eidest daughter Frieda was a down-to-earth girl, that even the peasants adored. But that night, five years ago, disaster struck. With the world hacing plunged into pure chaos, some bandits raided and set fire to the only chapel around. Unfortunately, that night, the entire Reiss family was there praying together." Hanje resumed the story of Reiss family.

"And so, the whole family, save for the head of the house, Rod Reiss... ...was massacred that night by the bandits. To top it off, this incident occured just a few days before Historia's mother was killed by the Interior Police. In other words, immediately after losing his family, Rod Reiss sought out Historia. There must be a reason he and his lackeys are after Historia." Hanje finished, making everyone taking in this information.

"The same bloodline?" Levi asked and continued with both of his arms crossed together. "Is there some secret to their blood?" Hanje shifted her head and exclaim towards him.

"I don't know for sure yet. But what really makes me curious is that parts of the chapel are completely wrecked. The chapel itself is stone. It would take tons of time and effort to destroy it. Bandits would take what they can and make a quick escape. Plus, the only one who saw those bandits was Rod Reiss himself. Soon after, he used his own fortune to rebuild the chapel. But why?" Everyone stare back to Hanje.

"If you think about it, it's actually stranger that there were no traces of titans. Even if I'm jumping to conclusions, something this suspicious deserves us checking it." She finished with her theory, Levi thought about it.

Eren opened his eyes slowly, after he saw a vision about Frieda, combing her hair slowly. Eren was shirtless and chained from both hands, he was kneeled on a tall edge.

The entire place was made with hardening titan skin, like Annie's ability that only Saitama could shatter at this point. The crystallized pillars seemed to hold the ceiling from above his head, the titan shifter thought with widen eyes while he was moving his head around.

'What the hell?!'

"Before the night is over, we'll have soldiers all over Reiss' land. I doubt he'll be waititng that long. Only Saitama might be able to save Eren from this point. If we or Saitama don't hurry and get there, Eren may end up being eaten. I just hoping our bald comrade is there to rescue him and Historia."Hanje exclaimed, Armin who was a little bit worried thought about it.

'If a titan eats a person who can change into a titan and thus inherits their power... if that's actually true... When and how did Eren become a titan, and who did he eat to gain his powers?'

Eren attempted to escape but the chains were preventing him. Even his ankles are chained and fastened on the crystal floor. 'Shit!' Eren cursed those chains and continued. 'If Saitama was here, he could rescue me and Historia!'

He shifted his head forward to only see Historia in a long white dress and Saitama with a piece of bread in his hand walking near him.

'Saitama? Historia?' The hero ate the last piece of bread and reply. "That's some tasty bread, oh Eren are you okay?" "Let me calm him down, Saitama." Historia's gaze shifted towards Eren. "Eren, you're awake? Just hang in there a while longer. Everything's fine." Saitama scratched his nose and asked her.

"Are you sure everything's fine? He might catch a cold, he doesn't even have a shirt on! let me help you." Saitama made a small jump and reached Eren with no effort. Historia's eyes widen in nervousness and ordered the hero. "Saitama, don't rush anything! I'll explain to you and Eren everything!" Saitama showed slightly disbelief in her words.

"Are you suuuure?" "Yes, Saitama. Trust me, now come down here." Saitama got confirmation from Historia, so he jump down again stepped back, right behind her and retort Historia with a bored expression.

"Okay, whatever you say, 'Queen.'" He tried to make a joke, but nobody laughed or even smiled, the hero didn't care either about his bad comedy, only the night was getting even more boring for him.

"Eren, Saitama, listen to me both of you. My father has been an ally to all of humanity within the Walls, for many years past and many years to come. We were clearly mistaken about him." Saitama lifted a finger and asked "I don't understand much but I'll try to." Historia shifted her head and gave a small smile towards Saitama.

"I'm talking about my father, who brought us here Saitama and it's true that he's been a problem for the Scouts, and his people did kill Pastor Nick... But he didn't have any other choice. Everything he's done, he had to do for the sake of humanity." Historia finished.

"Historia. Let me explain the rest to your protector and Eren." Rod took everyone's attention, Eren thought to himself.

'It's coming back to me... Yeah... The last thing I can remember is those three. How long has it been? Captain... Armin... What happened to the Scouts...' Eren's gaze turned towards the crystallic pillars before he thought once more with curiosity.

'What's up with these Walls, glowing like that...? I can't tell if it's day or night... No, hold on a second... Haven't I been to this place before?' Saitama, Historia and Rod reached Eren by using a staircase behind him.

"What's wrong? This is the first time you've come here. Though, it wouldn't be strange if you recognize it." Rod stated, while Eren was staring behind at them.

"No, I have never been to this place before. Also you can use a harder material to reconstruct this facility?" Saitama made Rod to shift his gaze and answer.

"I'm talking to Eren, of course you have never been here before, now please protector let the royal blood do the talking from now on." Saitama didn't get almost everything from this conversation. He could easily release Eren from these chains, but even Historia hold him not to do so.

'What does he mean by that?' The chained titan shifter thought in his mind, while Rod extended his arm with opened palm towards Eren's back.

"F-Father, explain to Saitama and Eren." Rod agreed "Yes, I intend to. However, there's something I want to try first, with Eren." His answer made Saitama to smack his forehead, the hero's face were completely bored now.

Him and Historia extended their hands, reaching Eren.

"If we do this, he may remember all on his own." Rod ended his words. Both him and Historia touched Eren's back, forcing him to remember the fight between his father and Frieda, also Eren remembered the night he ate his father.

Eren's gaze's completely empty "Did you remember? Your father's sin..." Rod exclaimed.

Historia had placed her hand on her head, she remembered her life as a child, Frieda were always with her.

She showed tears and took a step back. "What's wrong, Historia?" Rod retorted "Why? Why did I forget about that until now? I was never alone. That girl was always there for me. She gave me books... Taught me how to read and write... And was so kind to me... How could I forget about her?" Rod and Saitama faced her.

"You met Frieda?" Her father asked, Saitama gave his own question. "Can you explain me, what happened and who is that Freda?!" Saitama didn't care to know but this was the only way to avoid boredom.

"It's Frieda Saitama, and if it was a young girl with long, black hair the one Historia saw, it was most likely Frieda Reiss. She was Historia's half-sister." Historia and Saitama stare to him, Historia with widen and desperate eyes while Saitama with his neutral expression, Rod resumed.

"She must have been worried and came to check up on Historia's occasionally. If she was erasing her memories, it was all done to protect Historia Saitama, to protect you Historia."

He shifted his attention to his daughter. "Huh? Erasing my memories?" She asked worried "Yes, but touching your hand to him seems to have uncovered those memories again." Historia absolved from her worries and asked her father, Saitama next to her was picking his nose.

"Um, father? Where is Frieda at now? I'd like to see and thank her." Rod were gazing to Historia and her jumpsuit protector while she continued.

"If she wasn't there for me, I... I need to thank her for what she did for me then." Historia ended and waited her father's response.

"Frieda is no longer in this world. And I don't mean into another one like your protector was." Saitama shifted his shiny head to Rod, finally something interesting to chat with. "Oh? How you knew I came from another world?" Rod crossed his hands together.

"The rumors about you are true, you came from the sky. which means from another world, but Frieda is a totally different version of you." Rod stare back to Historia putting her in his hug and placing his hand on her head.

"Listen carefully too protector." Rod said to Saitama, the Caped baldy agreed "Huh? Okay" Rod begun to explain the story of his family.

"At one time, I had five children. But my wife and all of my children, Frieda included, were killed five years ago by his father, Grisha Jaeger." Saitama kept listening to Rod while Eren remembered what Grisha did.

"Grisha was a person with the powers of the titans. I do not know who the man was, but... ...his goal was to steal the power the Reiss family possessed. This power Grisha sought to obtain... It was the power of the titans residing within Frieda. Frieda's titan was superior to all other titans. You could say her titan had unsurpassable power. However... She did not have the experience to properly wield it. Unable to unleash her true potential, she was eaten by Grisha and he stole the power. But that's not all... He then attacked my entire family. His rampage sought to eradicate the Reiss family."

Eren couldn't believe what his father had done, he only kept listening with wide open eyes. "He crushed the 14 years old Dirk and 12 years old Abel. He trampled over my wife and 10 years old Florian still clutched in her arms. Lastly, he took my eldest son, Ulklin, and squeezed the life out of him. Miraculously, I was the only one who made it away." Rod finished explaining about Frieda and his family to her and Saitama.

"Unbelievable... That's how she... Why would he do such a terrible thing?" No answer, suddenly they heared footsteps coming closer.

"Hey, hey, hey, hey, hey, hey! What the hell are you guys blabbering about in here? I hope you know a buncha shit is going down outs-" Kenny stopped his phrase and place his hands on the handguns around his belt.

"You... ...at long last, we'll settle it." Kenny glaring daggers towards Saitama. "Who are you man? Did we met before? Saitama stated to Kenny with an innocent face.

"Kenny? What happened?" Kenny aimed at Saitama furiously.

"Firstly the Scouts started a coup d'etat and all the regiments changed sides. Everyone knows the king's a big fake, all the big shots ended up getting captured. And now I have the man my men told me about... right here... right front of me!"

"Oh? Ah... So you are Kenny! The boss of the dudes I crippled." Kenny shook his head and answered "Indeed I am bald devil, how about I demonstrate by planting a bullet in your thick skull, I truly want to know if my men were telling the truth about you being immune to bullets, and King is only matter of time till the Scouts show up here!" Rod jointed in the conversation.

"Kenny, lower down your weapons immediately! Saitama is Historia's protector, you won't spar with him. Instead leave us and take your anti-personnel control squad and defend the entrance. I believe I told you already that I need you and your crew to leave for the ceremony."

"Whoa, now, King. Did I make you mad?" No response from Rod "Sorry about that. But you can't be serious about that ma-" Rod said to Kenny with a serious expression.

"Kenny... My choice about him is right. I trust you that you will get along with Saitama too. Go."

"As you wish... King..." Kenny turned around and left the area who they were, cursing Rod from inside his mind, cause he didn't got a chance to fight Saitama. 'Tsk. That fucker is right there, and I can't even engage him, I know Rod manipulation on him worked, but I really want to test the bullets immunity theory.'

Meanwhile the opm heroes entered the aot world

A green portal cleaved the sky, unleashing the 4 heroes, Blast, Genos, Garou and Tatsumaki, their momentum's getting even faster.

"Hey Tatsumaki! We could use a hand!" Garou shouted to the ESper. "Hmph!" Tatsumaki obeyed, using her incredibly strong psychic ability to levitate Genos, Blast and Garou on the air. A green aura surrounded their bodies and stopped their speed tremendously.

"Deactivate it for me." Blast stated, making Tatsumaki and the others to turn their gazes on him immediately. "B-But Bla-" The #1 hero cut her off, shifting his spiky hair head towards her and saying. "You're not a kid anymore, don't act like one, I can handle myself." Tatsumaki's gaze turned serious while she disabled her power from Blast.

"See? All better." Blast were flying on his own. "You can fly?" Genos asked with awe.

"Fly and so many more, but now focus on rescuing your master." Genos nodded and thanks to Tatsumaki's psychic powers they following Blast.

"Hey? Are those down there people?" Garou asked.

"How the hell, I'm supposed to know? It's dark as fu-" Blast talk over Tatsumaki "Language!" Tatsumaki crossed her hands together and buffed her cheeks in frustration.

"Let's see if they know anything about Saitama, and I do hope they are not hostile or else..." Garou exclaimed and clenched his fists.

Levi and Mikasa had a talk on a carriage about the ackermanns' power. "Has there over been a moment where it's felt like power suddenly awakened inside you?" Levi asked.

"There has." Mikasa responded and finished.

"Who the hell are those?!" Jean shouted in utter shock, seeing and pointing at the S class heroes and Garou who were approaching from the sky above.

"What the..." Levi stated.

"Everyone! Prepare for battle!" He shouted, Mikasa and the rest of his squad pull out their blades.

Blast landed with his fist colliding to the ground, making it bend and shatter, revealing himself front of the scouts, his blue cape was waving heroically with the wind . "Hello strangers, We just want to ask about someone you might know."

"Like hell we'll trust an outsider like you! You appeared from the sky, like the baldy! Captain I'll handle him." Mikasa replied determined and launched herself against Blast.

"Mikasa wait! THEY CAME FROM THE SKY, AND THAT GUY'S WEARING CLOTHING EXACTLY LIK- GHHAH!" Armin was about to reply but a young man with sharp features, yellow eyes, and long silver hair that spikes upward in two large prongs, giving a feeling of a young wolf, launched a heavy kick on the blond's face, forcing him to fall from his horse.

The man had a lean muscular build. He wears a tight black, long sleeved shirt, loose fitting white martial arts pants, a yellow sash around his waist and tai chi slippers on his feet.

"Hey, hey! They are hostile!" Levi cursed the spiky white hair man, he shifting gazes between Armin and Mikasa.

"Damn it!" Levi stare on the sky to see a woman who had an adolescent face with emerald green eyes, and green hair that naturally curls up on the ends. She wears a form-fitting black dress with long sleeves, and four high-cut leg slits that show off her legs and low heeled black shoes. Tornado staring at him with a menacing expression.

"Who the fuck are you?!" Levi demanded to her, propelled himself and spin with his blades against Tatsumaki, but suddenly a glowing green aura levitate Levi and stopped his movements.

"What the hell?!" Tatsumaki float near and came face to face with Levi. "You're about to be REAL sorry for what you tried to do, you short noxious pest!" Tatsumaki slowly closed her palm and Levi was choking on his own, he thought 'What the actual fuck are those people!? My body doesn't listening to me!'

"You won't stop me from getting Eren back Bastard!" Mikasa shouted as she were ready to hit Blast. She missed miserably, the guy's so fast she didn't even see him dodging, he's right behind her.

"Heh you got spunk, you're quite amusing, but you better tell us what you know weaklings or else be destroyed, in the name of justice!" Sasha and Jean had no clue who they were going to assist first.

Genos landed next to Garou and placed his metal arm on Garou's chest. "Enough!" Blast and Tatsumaki heared him, the ESper didn't stop choking Levi though. "Hey Tatsumaki, put him down." Blast ordered and she did so. "Hmph!" She throw Levi on a tree like garbage.

Genos walk forward with Tatsumaki floating, Blast hero posing and Garou smirking behind him. "I'll explain who we are and why we're here."
