Before the Season 4 of SnK comes out I will uploading a few extra chapters here, that I make on my own.

Chapter 28 (Memories)

Our heroes were still at the beach, night time had come. Sasha was resting on Saitama's lap while he was next to Genos and Erwin. They were watching the endless sky with countless of stars.

"I can't believe what we have discovered about humanity and our brand new foes. And it's all thanks to you heroes, if you wasn't with us in Shiganshina we wouldn't make it without casualties like hundreds deaths of soldiers." Erwin said and grabbed Saitama's attention.

"Oh, it's our job to protect and help people, we can't let them risk their lives out there against villains and monsters." One Punch Man stated whilst he was patting Sasha's head.

"Exactly! Commander Erwin, as long me and my Master are around, humanity has NOTHING to fear of! We will exterminate whoever try to destroy the innocents called subjects of Ymir." Genos exclaimed and took both Saitama's and Erwin's gazes.

"Ah, yes the subjects of Ymir... It seems me, Levi, Hanje and everyone else in the three Walls are those called 'subjects'"

Erwin continue while he was toying with the cold sand and placing his palm underneath it.

"Unfortunately I don't think the same about you heroes, since you came from another world, you have nothing to do with the 'Curse of Ymir' nor the history of our cruel world. But you are really here and helping us with your immense strength and superpowers. That's enough for everyone to believe that freedom exists outside of the Walls." The Commander stared at the stars and finished his words.

"From... Another world... Yeah..." Saitama mumbled with a neutral expression while he was staring the dark sky being lighted with stars.

"How about you tell me more about your world now? I want to know like everyone else here." Erwin got interested in finding out more about the world of the heroes.

"Good point, how about you tell us too." Levi and Hanje approached them and sat down around them.

"Genos, can you please tell them cause I feel sleepy."

Saitama's disciple nodded and shifted his head at Levi while Hanje and Erwin were watching and hearing with particular interest.

"Alright, I have a lot of memories from our world. From where should I start?" Genos holded his chin thinking.

"Tell us about your society." Erwin said with a serious and excited tone at the same time.

"Very well, here goes." Genos cleared his throat and began the tale of their own world.

"Our society lives in freedom, they have built cities with countless and multiple story buildings, our world's technology is far beyond of what you people know, and the brainless beasts you call titans are nothing compared to the monsters of our world."

"Saitama told us a year ago a little bit about those monsters. Are they truly how he described them to us? With claws and sharp teeth?" Hanje asked while she gave a big smile toward Genos.

"That's the most common features you will see on a monster of our world, most of them possess powers like us and they trying to cause terror and chaos but that's why the hero association exists! To send all of those monsters back to hell."

Genos took Eren's, Mikasa's and Armin's attentions, who were sitting a few meters away.

"From what you saying, our blades would be useless against a monster from your world right?" Levi raised his eyebrow and told Genos with his serious tone.

"If the monster's threat level is beyond tiger yes, they would be completely useless." Genos said and nod.

"What you mean threat lev-" Hanje cut Levi off and reply "There was ever a time you and Saitama spar against each other?"

Genos changed his glowing eyes gaze and placed it on Hanje. "I'm surprised you're curious about something like that, yeah there was once long time ago. When I had doubts about my Master's power. I asked him to fight me in the first place, he agreed and then we set off."

"What happened next?" Hanje asked with blushed cheeks and a massive smile.

"I failed miserably, in the entire fight I thought I had a chance against my Sensei, but I'm was only fighting his afterimage. He was too fast for me to notice at the beginning, at the end when I told him to be serious for the fight he changed mood, he appeared front of me serious and before I could react he reappeared behind me and launched a punch so big that could be described with only one word... Death." Genos stopped and stared at Hanje, she was shocked from hearing such battle.

"How didn't you die?" Levi asked and Genos answer him.

"He stopped 1 inch before his punch land on my face, I would be dead if that was a direct hit. But my Sensei showed mercy, after that his mood changed into his calm looking one and patted my face, telling me it's time for lunch. Of course I agreed and followed after him with utter shock."

Erwin smiled and said "Good for everyone to have Saitama on our side." Genos nod and responded

"Indeed, my Master is the strongest hero, no monster, human or titan can defeat him." Saitama looked away and focused his gaze on Sasha while she were sleeping on his lap.

"Your society lives in peace you said?" Eren asked calmly Genos "Yeah, like I said before." The cyborg stated with a serious expression.

"Would you mind joining us here?" Eren asked Genos with interest in his tone. "Alright." Genos stood up and left his Sensei and the others, he sat down next to Eren's trio group.

"So, so Genos. We heared quite a lot of impressive things your world have." Eren replied and Genos answered immediately.

"Compared to this world, yes I agree." The cyborg's gaze shifted on Mikasa whilst she was staring the sea.

"Hey, are you okay? Mikasa." Genos asked her with a slightly nerve. "Me? No, no, it's nothing."

Genos didn't fall for that, he insisted. "You are sweating, there's something you can't tell us?"

Armin joined the conversation worried "Genos is right, is there a problem Mikasa?"

"No, I'm just tired and need sleep. Thank you all for showing interest though." She layed down and turned her head away to end the conversation.

"Nevermind, awwww! I guess we all need sleep." Armin exclaimed to them, both Genos and Eren nodded in agreement.

They closed their eyes and slept peacefully.

Few hours later

It was still night everyone were sleeping but suddenly Mikasa heared a weird cracking noise and woke up.

She thought inside her mind 'Could it be... I need to investigate this alone!' She get up slowly without waking and alerting anyone else, she walk several meters away from the camp, but didn't saw anyone nor a titan.

"You are full of surprises, Mikasa." She heared a very familiar voice behind her and turned around almost immediately to explain.

"Eren! Let me expla-" She got shocked, it wasn't Eren but the guy that had the same voice, Speed-0-Sound Sonic.

"Sonic..." She blushed and covered her face with her red scarf. "You knew I'm was following you all these months, am I right?" Sonic asked her with crossed arms.

"Y-Yeah, I did knew it. I even remember what you told me back then... In Shiganshina." Sonic smirked hearing her words and respond.

"True, I didn't lie about that, stay close to Saitama and you will keep seeing me around."

"Why don't you kill him now, he's asleep!" She said determined.

"You don't care about him at all? You are in the same group." Sonic asked her.

"That bald man ruined my life as long as he first appeared, he has strength, power, speed, courage but most of us lack that! If he wasn't here, I could protect Eren on my own!" Mikasa answered furiously.

"I see." Sonic mumbled "So please Sonic, kill him now! It's your chance! We will all get rid of that bald bastard!"

"No, I need to kill him when he knows about his demise, I will defeat him on 1v1 combat someday!" Sonic finished and clenched his fists.

"Fine, if you say so then, so Sonic, can you tell me when you fought with Saitama?" Mikasa asked whilst her scarf had her shy face all covered.

"I have fought him 3 times. Everytime I'm was failing to even injure him, the guy seems invincible, but I won't stop. I still have those horrible memories when he defeated me again! Front of his appartment."

Sonic walk closer to Mikasa and she exhaled in embarrassment.

"I remember... Saitama decided to fight me seriously due to my persistence, to which I gleefully replied that I will show Saitama my newly developed technique. Even 10 afterimages wasn't a challenge against Saitama, he did one of his moves and it was all over for me."

Mikasa shook her head to consoled Sonic. "Strength is not above all Sonic! Immense and supernatural power only brings negative emotions to everyone else around that person who possess it. Like jealousy, egotism and even greed. Everyone else including you and I lack of that, but we have an unbreakable bond called friendship, hearts and love!"

Sonics raised an eyebrow toward her and they made eye contact. "You talk wise for your age, I won't stop till I get my revenge on Saitama, but I'll keep what you told me in my mind. Thanks Mikasa."

"Your we-welcome..." Mikasa's face went bright red "Sonic... Why you live like an outsider? Accept my request and come with us please!" Sonic stared at her in his serious mood with still his arms crossed together.

A moment of silence between two cold hearts, only the wind were making their red and purple scarfs to move on their own.

"Alr-" Someone cut off Sonic by placing his hand on Mikasa's shoulder.

"Mikasa? What are you doing here all alone?" It was Armin and he seemed worried about her. "I'm not alone, I'm with Son-" Mikasa shifted her gaze to where Sonic was but he had vanished from their eyesights.

"Armin, it was him... the guy..." Armin's eyes widen in shock and reply.

"Th-that guy from Shiganshina?!" Mikasa nodded while she were staring the horizon with sadness planted on her face.

"Commander Erwin must know about this." Armin stated and they procceed to go back to the beach camp.

Mikasa laid down next to Eren and Armin, under the warmth of her sheets and blanket. Her cold face were staring at the star-lit night sky whilst she mumbled in a cute tone.

"Sonic..."

Next Morning

Everyone woke up except Saitama, Sasha was kissing his cheeks gentle. "Hey! Egghead! Avocado! Wake up!" Tatsumaki shouted to Saitama with mad voice.

Saitama woke up and right after he opened his eyes Sasha completely ignored Tatsumaki and gave the hero a kiss to his mouth.

"Good morning too, Sasha." Saitama slightly smiled toward his girlfriend.

"Hey! Stop ignoring me!" Tatsumaki shouted to the couple and grabbed One Punch Man's attention.

"Calm down sassy child please, I just woke up." Tatsumaki shouted on Saitama's bald head even more furiously.

"I'm not a sassy child!"

"Calm down Terrible Tornado, we don't want heroes to fight each other." Erwin stated and calmed Tatsumaki down.

"Hmph! Whatever." She looked away with disbelief.
