CHAPTER 1:

Mmmmmmmm... So soft...

I felt the soft blankets around me and decided to curl up around them, wrapping myself in them like a cocoon. Were they always this soft? It was unbelievably nice, but it felt rather unfamiliar for some reason. Opening my eyes I immediately noticed they were not my beloved white blankets. They were of a different color and had a completely different design, and I don't remember having switched them out recently. Wait a minute... this isn't my bed either! The hell is going on!

Startled by the sudden change in bedding I sat up and quickly glanced around. Observing my surroundings I quickly deduced that I only was not only not in my bed, but upon moving my body and staring at my hands it struck me that my physique had changed too. They looked something like, I wouldn't describe as cleaner, but like they'd been touched up somehow. What was going on... did the rest of my body change? If that was the case then what did I look like now? Uh, where to tell... OH! Over there, a mirror!

Getting out of bed I walked towards it through the strangely clean and fancy room, thankfully and for some reason the mirror was oversized, and gave me a view of my whole body. I was now tall, a little- a lot more lean, and with delicate looking light blueish hair, and a pretty male face that had no right being that attractive. Obviously due to me being a fan of the series this particular man came from I could clearly tell that was... the famous A Class Hero Rank 1 from One Punch Man... by the name of Sweet Mask! Amai Mask? Handsomely Masked Sweet Mask? Whatever translation it was, or what this world used. But that's besides the point, I was now many things! A hero, pop idol slash celebrity, physically strong, and most importantly... attractive!

Did I have his memories? Or was this some sort of weird surreal dream? My question was answered by ear splitting headache, followed by myself falling to the ground screaming and writhing in pain for a few minutes straight. Like a seizure and full body stroke. When the pain went away I miraculously found that I possessed all the guys memories. The entire life of Beaut, Secret Mask, and Sweet Mask, up to this point in time, at the age of twenty three. So not a dream. Definitely one of these weird displacement scenarios.

Was this good? Bad? I couldn't tell, but I was leaning towards this being positive. Being handsome was definitely a very big plus since in my previous existence I was about average or so, and could be visible compared to one of those male nerdy Disney protagonists with curly hair and a big nose, a completely and utterly average looking young man. My previous life was also painfully normal, and painfully boring, so a to be able to life life in another world as a world famous celebrity was fucking amazing!

There were however two very minor minuscule things that I thought could potentially be maybe problematic for me living here. Firstly the fact that I was not human anymore as my memories had told me, and the other fact being that Cities around here had the possibility of being vaporized near instantly by randomly appearing monsters, aliens, of pseudo God empowered evil humans. So this world wasn't exactly safe to be in. Well... Tatsumaki and Saitama could deal with those threats pretty easily, so I probably didn't need to worry too much about any world ending threats in all honesty. I wasn't the protagonist here, and I was god thankful for that.

But I was important... and I guess I was technically a hero too. A Class rank 1. Damn, and here I thought I could finally escape the responsibilities of life and hermit out. But now that I had suddenly been displaced into an anime character with a pretty good sized influence over the world I guess I had to go and practice that whole 'With Great Power Comes Great Responsibility' thing. Theoretically I could just hide somewhere... and play video games in isolation like I normally so... but... since I had the power to easily help people I couldn't just avoid these problems. Also Beaut's obsessive desire for justice added onto my own consciousness seemed to have given me an overwhelming desire to help people using my future knowledge, and so that wouldn't allow me to let people die off that where I could easily prevent it with little effort.

Might be a monster now but me and Beaut were also a good normal people at heart, berating heroes for not fulfilling Sweet Masks impossible standards notwithstanding, and so as how any well adjusted morally good person would do I decided that helping society and preventing people from dying was at my sole responsibility, for now.

With Sweet Masks memories and my own seeming to have merged together, for some inexplicable reason, I now found that I had also gained quite a bit of combat knowledge and his own acquired abilities. Singing, dancing, acting... modeling... and many other miscellaneous skills for the celebrity life. But the knowledge of my own abnormal strength was good, at least I wasn't going into this blind without knowing how to fight.

Although most of the larger threats tend to get obliterated by Saitama quite easily, so there was also that to take into consideration. That made me feel better about the monster fighting part of heroism. Even though apparently I was strong I had no clue what sort of enemies I should measure myself against, most if not all demons probably since I remember Sweet Mask was able to hold his own against Black Sperm... Well a hero didn't always do fighting though! Gotta help rescue little girls cats too, and uh... look good doing it? Memories alerted me that the original Sweet Mask pre-transformation would've done that with no complaints, but now as celebrity and icon that was something Beaut would say to be left to the C Class. I understood that a bit, even if they were above humans a lot of C were pretty much fodder, but I wouldn't let that new ego get to my head and cause me to disrespect people for their hard work. The little things mattered too, and I wanted to rescue cats! They were one of my favorite animals after all.

Oh! Ringing, from a flipphone on the table, dammit why did it have to be one of those. Whatever I knew how to use it now, guess I'll pick that up and listen. Still trying to figure out what to do with myself here, maybe it's the self insert random omnipotent being calling me that'll give me all the exposition I need to figure out what's going on through the use of witty remarks? Ha ha...

"Beaut! Did you have a good morning?!" Nope, I was wrong. I did not recognize that peppy female voice whatsoever, why was that?! But of course I couldn't tell her that. Needed to play it cool, at least my own lack of significant social skills were replaced by Sweet Masks own above average ones. However the lack of knowledge of who she was concerned me.

"I'm as great as always, but what about yourself?" I spoke softly, surprising myself with how smooth my voice came out. Damn, this was kinda trippy.

I decided to redirect the conversation back to her, hopefully she'll mention something so that I can learn what's going on... and who she is.

"Of course! Honestly as your new secretary I'm really excited to be working with you! Hopefully I can meet your expectations, since I just got the job from the recommendation of your previous one. Sorry for rambling!"

New secretary... OH yeah now I remember. Okay that made sense, the old one retired and was going to have their replacement call me. I was thankful for having a secretary. Delegating someone else to make appointments for me made realistic sense, me being a busy and important man after all. Although the downside here was that I was now personally conflicted if I really wanted to do any of that pop idol, acting, or singing stuff that the actual Sweet Mask did. I mean I can it easily now since I have the memories of how to, but with my with my new personality and other set completely different memories I was reconsidering if it was the best use of my time. Relative to being a full time hero who was actively saved lives. My Sweet Mask psyche was telling me that it was fine either way, since lives were on the line if I ignored things, but things would also be resolved if I kept up the image.

Before I could think up a response to stall having to figure out what to say, my secretary continued speaking.

"Anyways we have a pretty slow day today! A commercial at two, another one at three, then a hero association meeting at four, a movie scene at six, and finally an interview at seven."

Slow day you say...? Well in comparison to going to different gig every hour yeah. Being inhuman gave me nigh infinite stamina, so all these activities wouldn't make me tired per say, but as I thought about before it'd take up time of me being a hero. So with being a full time hero I just might have to retire from all this idol work. As ego boosting as it was for my new psyche I needed to help fix a few plot related things before I start being lazy, putting Saitama in the limelight being one. fixing the Hero Association being two, and dealing with the Monster Association being three.

"Hey, do you mind if I make a few adjustments to my schedule?"

"Absolutely! What do you need to change?"

"Could you cancel everything today except the Hero Association meeting and interview?"

"Oh, uh, okay! Did something else important come up?" The secretary asked me with a little concern in her voice.

"I just wanted the day off today, that's all." I said nonchalantly.

"Will that be all sir?"

"Yes." Click.

Now I was now free... sort of... I needed to figure out what of my current three objectives I should do first, and if there was other things I needed to do to either save lives or help out mankind.

Something.

Uh.

Hrm.

Maybe I could play some video games a little first? Just a little personal indulgence you know, to clear my head for the future.

Can I- no Sweet Mask, or Beaut doesn't play or even own video games does he...? Shit, I wanted to play a little before I do important stuff.

Suddenly it dawned on me, someone in this world did indeed exist who was capable of understanding my plight and who also played video games, and was very plot related. The S Class Hero King! He's probably read an isekai manga or two, so surely he could be my confidant in this peculiar situation I've found myself in! Yeah, maybe I'll go see where I am in the timeline from him too, a good starting plan! To City M!

Mmm, I need a shower, and to get out of this robe. Where is that again?

...

Hmmhmm closet, open, this should not be as big as it is. There's probably hundreds of outfits in there... guess I'll go search for something to wear.

Suit? No. Any of my normal clothes? Maybe, my new psyche at least gave me an idea of what was stylish and professional, so that was helpful.

What's this? Oh yeah that's right, an actual normal superhero costume. Sweet Masks hero persona known as Secret Mask. Yeah, about as creative as you' expect. Especially alongside heroes like Funeral Suspenders or Smile Man... hmm, the outfit wasn't too bad really. Yeah, I'll wear this... when I start my hero work back up again. I think it would help me make up a good excuse for giving up idol work, having a change in heart and wanting to become a hero of justice full time. Mmhmm, I liked the sound of that.

Probably would keep the same hero name for simplicity sake, and not wear a mask. Tried it on and it was surprisingly comfortable. Meh, I'll wear something else for today. I didn't consider myself technically on duty yet, wanted to check in with King before putting on the outfit and jumping into combat. So the hoodie it is! And a mask, a medical one. To hide my identity like how King does.

Alrighty so shower, outfit, check. Not sure what else I could really do in my house besides explore, there isn't anything particularly interesting in here to mess around with. So journey time!

Phone! I know how to use a flip phone now. Ok uh lets see here, contacts, names and other names I recognize... oh there we go 'Transportation'! My own personal transportation service why? It was because I was rich, what a nice convenience.

...

So I had my own on call jet, helicopter, and other drivers, including a limo. This was mainly due to my status as a hero and celebrity naturally, since I was a kind of a big deal around here. If I didn't have all these memories of using it I might find this a bit weird, but calling for a ride felt as normal as any other activity.

To be discrete I chose a simple car ride, and while it took longer to get to City M then the other options I felt it better suited the new me. I wasn't one that really liked to participate in an overly fancy lifestyle, I used to be a normal dude after all.

Alright in the streets now, medical mask and hoodie was on and snug. This is kinda uncomfortable with the sun, but it was absolutely better then being swamped by people. Where does his majesty live? Over there in that familiar apartment building? Hmm, how do I approach him without causing a scene. Didn't know what apartment number, and I wasn't sure about asking them for it.

I'll just go wait around outside in the shade, I'll see him with enough time. Right? Surely he can't just hide in his apartment the whole day...?

With the subtly of a mouse I waited and sat down at around a little nearby coffee shop. Mindlessly staring at the passerby civilians.

I waited around awhile, a few minutes turned to ten minutes, and half an hour passed before one of the female workers asked me if I planned to order anything.

Revealing my face for a split second I explained I was undercover and engaging in an important mission. She took the excuse, naturally. I just got water

Another ten minutes or so passed and I finally saw the man in question, being able to tell it was him by the familiar light blue colored hoodie and his noticeable height. He seemed to be holding bags of produce, most obviously groceries.

Well here we go.

Catching up to him inside the building I followed him into the escalator. Upon us being alone I took off my mask and spoke up.

"King." I said simply said.

"Sweet Mask? What are you doing here?" He seemed surprised.

"King, I wish to speak with you for a moment. I know you're secret."

"W-what?" In that moment the King Engine began rumbling, if I hadn't know that was his heart I might be kinda freaked out right now.

On second thought I was actually freaked out, because it was his heartbeat. That didn't sound healthy at all, if he wasn't S Class I'd recommend he go to the doctor to get that checked out.

"Don't worry, I just want to talk. That's all. It's nothing you should be concerned about. Really we're both in a similar situation." I explained.

I could hear the legendary King Engine ever so slightly calm down. The rest of the time waiting in the elevator was an awkward silence and the Engine's rumbling. As the door opened I promptly followed him into the Strongest Man's messy apartment.

...

"So that's my situation here." I explained to King my unusual circumstances in full. Being from another world, this world being a manga and anime from my point of view, me being displaced into Sweet Mask's body and mind, then me having knowledge of certain events that occur in the future.

King had a softer, less but still scared, and more thoughtful expression. "Well uh, I'm not sure what to say here. That's an... awful lot to take in. You said you got his memories too right?"

"Yep! It was really painful actually. But it makes life a lot easier, otherwise I think I might've just run away."

"Hmm." King seemed to consider more, before talking again. "That's cool... I guess, it explains a bit, and how you know he truth about me. Uh, why are you here again? If you already know I'm not strong...?"

"Oh I just wanted to come over to play video games. You and I are a kindred spirit you see, a fellow fan of anime and manga... Plus I need you're intimidating aura and reputation to help me out in some situations."

"Do I have much of a choice?"

"Absolutely. You could sit here and waste away playing video games, one day leaving the house only for some monster to kill you, or you could use your reputation to help me fix the worlds major problems and save lives, while also being protected by yours truly! Your choice, no pressure."

King sighed deeply. "Jeesh. I guess if you put it like that... I don't have many other options then... I guess I'll join."

"You won't regret it!"

...

Naturally as a starting bonding exercise we played a cooperative RPG, as I planned to do with him before. And King was fucking stealing every item in sight.

"How strong is Sweet Mask anyway? I know he's at the top of A Class, but is that just because he's famous or is he stronger then he looks?"

"Nah he's the real deal. I could probably solo a few dragons. Actually I'm not even human, apparently I can survive dismemberment and shape shift."

King choked upon hearing that, yet that didn't seem to deter him in game as he still was able to steal all the healing potion I needed by just a hair. Damn it!

"Wow r-really? How did- do people find out?" King spoke in a worried tone.

"He had to transform, technically sacrificing his Sweet Mask persona to fight a dragon. But otherwise I'm pretty sure my disguise is perfect. I'd experiment with it... but I don't wanna risk it."

"A-alright. He didn't have any murderous urges while he was in human form did he? I think I would've liked to know about that..."

"Sweet Mask was a great hero at heart, having sacrificed his persona to save more lives... he was just a little too obsessive with justice, and maybe just a little murderous, but I think my merging with him cooled those feelings down. After merging I developed some memories of the same feelings of black and white justice about the world but it hasn't seem to affect me too much, despite having his mind melded with my own I still feel more like my original self. Can't say why really though."

"Huh. Must be nice being able to live in an anime... filthy rich, and be able to get with any girl from it. Seems like you got easy mode to me."

"You're about half right. But it's not really the same if people like you and base their opinion on you for something you've never done. I mean I've merged with the guy, but this doesn't feel normal. Obviously because it isn't even a real body, just some advanced shapeshifting. I mean everything feels like a normal body... but everything also just feels different." Despite the passage of time I didn't particularly feel hungry, though I could probably still eat.

"Oh, I guess that's true. Not being human must suck. You going to... continue in his footsteps?"

"Tch, hell no! I don't wanna sing and dance for fangirls like some pretty boy, even if I look like one now. I'm an anti-social recluse at heart just like you! I'd much rather wear a costume and kill monsters like a badass. I have the strength to soit, so I don't wanna waste it playing a character."

King nodded "That sounds like the right thing to do. When do you plan to start working again?"

"I was thinking sometime today. Wanna go raid the Monster Association base later?"

"W-what? Monster Association?!" The King Engine started.

"Oh yeah, I planned to mention it... but there's like over eight dragons and hundreds of other monsters hiding under the City Z ghost town. You guys and Sweet Mask raid the base and eventually win, no losses thankfully. In fact we should probably handle that today, maybe even now." I mused.

"R-right now?!?!" The Engine was blaring now, and King himself paled.

"Yep, I was thinking we could go to City Z together, then you could call all the S Class in as reinforcements so we could wipe them out all in one go. With the Monster Association none the wiser. We could probably hide out and pretend to guard the outskirts of the area, actually I was thinking we go and recruit Saitama for good measure."

"Who's Saitama?" King inquired.

"He's the guy who saved you from that Octopus who scarred you. Trained himself to near death for a few years and now he can one shot anything, but the guys kinda bored of life now though. In the original timeline you guys meet and become friends. He lives in City Z too, and he's the protagonist of this world that I mentioned."

King sat silently as the game was paused. His eyes were closed in thought, thinking over Sweet Masks words.

"I-I don't have to fight anything right? Just call in everyone else and we let them take care of it?"

"Yeah. Tatsumaki could probably blitz the base herself, but there's a couple tricky dragons that might be problematic. So as a safety net I was thinking we get the whole gang together."

There was another minute of silence before King responded. "... A-alright I'll do it, just because I know the Association will call me to help come over there anyway... and I guess I want to give Saitama my thanks too."

"That's the spirit!" I gave King a reassuring pat on the back for good measure, though that seemed to have restarted the Engine back to full force.

"I was thinking of wearing Sweet Masks old outfit so I can look the part of my new self, so we'll have to drop by my place real quick yo pick up that up. Then it's off to City Z!"

"A-alright." But King in fact did not look alright, he looked absolutely terrified.
