Jakarta, Indonesia

"Jadi…..ending-nya begini? (So...that's the ending...)" A teenage boy can be seen scrolling through his phone as he reads the final chapter of BnHA. This boy is Will and he is enjoying his college vacation in his home country, trying to take breaks from college-related stuff.

"Jujur saja, saya agak….kecewa…(To be honest, I was a bit...disappointed)" The boy sighs as he close his phone. "Gua harap ceritanya ga berakhir begini, Midoriya kehilangan kekuatannya, dan walaupun timeskip-nya berakhir dengan Midoriya balik menjadi pahlawan bersama teman temannya, saya merasa kalo orang orang di Jepang melupakan apa yang Midoriya korbankan demi seluruh Jepang….(I was hoping the story didn't end like this, Midoirya loses his powers, and even though the time skip ends with Midoriya return as a Pro-Hero along with his friends, I feel like people in Japan forget what Midoriya sacrificed for the entire country.)"

The boy looks at the phone once more and yelps in panic, noticing that he has spent most of his time binging the remaining chapter of BnHA. He can't help it, especially when these few months he had to deal with his college's final year project, assignments, and homework, which leads him to always sleep late at night. It had become his daily routine that he tends to forget what time he's supposed to sleep.

Right now, the clock on his phone displays 2:50 AM. Will never felt so panic in his life, especially when spent the entire night reading without taking any dinner. He curses himself for getting addicted to the last remaining chapters of BnHA that he forgot to take care of himself. Immediately, he could feel his stomach growling as he sighed. He got up from his bed and started to walk out of the room, hoping he could cook some instant noodles, especially given how everyone in the house was sleeping like a baby right now.

"Gua benci diri gua sendiri….(I hate myself...)" Will mutters in annoyance. "Bego….tolol…kenapa lu harus ampe lupa makan, jir…(Idiot...dumbass...why do you forget to eat again?)" Will sighs as he reaches the kitchen and turns on the light. "Oke-! (Okay-!)" Will froze when he saw a masked figure trying to crawl in through the window and another one trying to help the figure, both froze when they saw Will.

"Maling! Bangsat! (Thief! Bastard!)" Will grabs a nearby frying pan and slams one of the masked figures on the head before he tries to pull a knife from his pocket, causing the figure to yelp in shock and pain. Will immediately targets the one trying to crawl in by smashing his fingers, causing him to yelp and fall, making Will freeze in shock and letting the gravity of his action sink in. The other figure roars in anger and tries to stab Will, but he hastily smashes the frying pan onto his head, causing the man to cough blood.

Before he could do anything, he heard a gunshot and he felt an immense pain in his back as he violently coughed out blood. Will turns around and widens his eyes in shock as he sees a third masked figure holding a gun, pointing at him with smoke coming out of the hole. Before Will could register anything, he felt a sharp pain in his head before everything turned black, with one thing left in his mind.

'M-ma….Pa...semuanya (Mom...Dad...everyone).'

"Gah!" A boy with messy green hair gets up from his bed in panic as he holds his head in pain, wincing as he holds his head, feeling like he has just been shot.

"W-what was that dream!? I…." The boy mutters before looking at his hand. "Scars…..right, cleaning those beaches and dealing with Bakugou…." The boy blinks at himself. "Bakugou? Wait, I always call him Ka-!" The boy instinctively shudders.

"…..god, I….my head was a mess….why is that dream feel so real…?" The boy shakes his head, his vein throbbing. "I…..why can't I recall my name….wait no, it's Izuku Midoriya….Deku…" In an instant, images of manga panels and anime scenes flash in his head, causing the boy, Izuku to clutch his head in pain. "Argh!"

"I-Izuku!" Izuku flinches when he hears a familiar and somehow, unfamiliar voice calling him before the door is open, revealing a short woman with long green hair, sharing the same face as Izuku. "Is something happening, dear? I know I should've stopped you when you started to overwork yourself while training for UA's entrance exam!"

'Overwork? Training? UA? Entrance exams…?' In an instant, more images of manga panels and anime scenes flashed in his head, he winced in pain before then he heard another familiar and unfamiliar voice.

"Morning is here! Morning is here! Morning-!" The woman immediately turns off the alarm. Izuku turns to see the alarm clock with a familiar color palette, before looking around to see the image of a bulky blonde-haired man. Slowly, his mind starts to be clear as he finally remembers everything.

"…..fuck…" Izuku mutters as his eyes turn wide, his face turning pale.

"I-Izuku?" Izuku turns to see his mom giving him a concerned look. Izuku shakily smiles at her.

"I-I'm fine…I….just having a headache f-from nightmare…" Izuku lies at her, his hand gripping the blanket tightly. His mom (Inko Midoriya, the fandom's best mom) gives her a concerned look. "I'm fine now, mom. Just….having a weird dream…" (My mom's Inko Midoriya….what…)

"…okay..." Inko says before she left Izuku alone. After she left, Izuku gripped his head as his eyes grew wide, and his entire body sweated like crazy.

'Fuck, fuck, fuck. This can't be real, this cannot be fucking real! I'm in BnHA and reincarnated as Izuku Midoriya of all people?!' Izuku (Will) thought in panic, wondering how this happened in the first place. 'And why did it take me 15 years of life to finally remember my past life?! I live through as Izuku Midoriya in a blank state, an actual newborn, dealing with the bullshit named Bakugou Katsuki, and-, and-, everything! GAH! Why now, why now!?'

Izuku let the gravity take over as he collapsed into the bed, staring blankly at the ceiling while wondering what exactly is his life now. He wasn't unfamiliar with his current situation, as he reads isekai manga besides BnHA. One particular manga he read is Trapped in Dating Sim since it reminds him of his current predicament. Going through life for several years while oblivious to his past life until one particular moment of his life.

'But, unlike him, I didn't remember until a very long time. Wait, what date is it?' Izuku turns to see his calendar and widens his eyes. Today's the entrance exam and he's supposed to accept One for All today! Izuku hastily gets up before pulling out his tracksuit (It's one ugly tracksuit!) and rushes towards the bathroom, brushing his teeth and washing his face, then changing his clothes before rushing off.

"Bye, mom! I'll be back later!" Without waiting for his mom to reply, he closes the door and immediately runs towards where Dagobah Beach is. He had gone there every day for the past 10 months, so he remembered which path he should take. It takes him a while, but he manages to get to the beach. He pants for a moment before noticing the leftover trash he hadn't finished cleaning before he went to clean it. As he cleans the beach, his mind goes into overdrive.

'Okay, calm down, Izuku (I should start calling myself that, it's my name now…..I guess?). Think of the bright side, now that I remember my past life and thanks to my knowledge of BnHA, I could use it as an advantage. One of them is my knowledge of OFA. That means I won't have to shatter my bone like some masochist. All I need is to let the energy flow around my body, like how microwaves heat the entire side of food instead of just one side. Ah, fuck, that metaphor again…..I wanna facepalm when I read it, and now I made one myself. The fucking irony. I should control my cursing or else mom will kill me. Ah, fuck, my mind's a complete mess. Am I Izuku Midoriya or am I Will, or am I both!? Why does reincarnation have to be so confusing!? Does this count as classic isekai, or the usual transmigration, because I no longer know!' Izuku thought as he tossed away the last trash away with more force than normal. He's at the top of the trash, looking at the sun slowly rising from the sea.

Izuku blankly looks at the rising sun before he takes a deep breath, annoyance builds up in his chest as he clenches his teeth. Flashes of memories of his past life, more specifically the moment he got shot twice in his back and his head, the time he accidentally committed murder, and then, his past life's family, their fates are unknown. To make it worse, it's been 15 years since he died and was reborn, the possibility that they have died struck him like thunder. With all the thoughts running in his head, he let out a yell.

"RRRAAAAAAAAHHHHHHHH!" Izuku let everything out of his chest. After a few seconds, he stops as he catches his breath. He feels somewhat better, but his frustration remains there. Before he got a chance to break down in tears, he was interrupted by something.

"Whoa!" Izuku blinks before he snaps his head towards the source of the voice, his face slowly turning pale as he recognizes the face of the person in front of him. The spiky black hair with a pair of red eyes and teeth similar to a shark, wearing the usual school uniform. The boy in front of him is Eijirou Kirishima himself, the 'manly' guy who sticks to Bakugou like a lost puppy. "I can't believe it! I thought this place was still a junkyard, based on what the news has mentioned! To think I would see the beach in full glory and the guy responsible for cleaning this place at the same time! This is amazing! Uh, wait, a-are you crying!?"

"I, um, uh…" Izuku was unable to reply, too surprised at the boy's sudden appearance. 'H-how is he here?! I wasn't supposed to meet him until I at least started the first day of school, and that was just seeing him in class and doing the Quirk Apprehension Test! I swear, this wasn't supposed to happen! D-did I somehow cause butterfly effects just by remembering my past!? I get that a small action is enough to trigger it, but this is beyond ridiculous, like that 'Time Travel Sneeze, Entire Timeline Fucked' meme!' He pauses for a moment and remembers what Kirishima said before he wipes his tears off.

"H-hey, you're okay there?" Izuku snaps out of his thought before looking at Kirishima giving him a concerned look.

"Y-yeah, I…was just not expecting someone to be here…It's why I plan to yell in the first place…" Izuku mutters the last part quietly but is heard by Kirishima.

"Oh! Don't worry about it, I won't tell anyone." Kirishima says while giving him a grin and a thumb up.

'That's the problem! I don't want anyone to know!' Izuku mentally cried.

"But….why are you crying?" Kirishima asks in concern.

"It's….personal." Izuku didn't want to tell his problem to a random stranger, despite knowing who the boy was. Then again, he's trying to avoid being a creep.

"Oh, right…" Kirishima pulls out a phone before looking at Izuku. "I was wondering, do you know the nearest bus stop from Musutafu Train Station? I try to search for one but I can't seem to find it." Izuku's mind turns blank when he hears Kirishima's words, his eyes widen in utter disbelief.

'Nearest bus station….from Musutafu Train Station…' Izuku thought, staring at Eijirou incredulously. 'Bro, the nearest one is basically beside the exit, which is like 5 kilometers from here! How did you get from there to here!? You're telling me Kirishima's non-existence sense of direction from the movie wasn't supposed to play for laughs, but a real shit!?'

"….Ya ampun, baru pertama kali gua ketemu orang nyasar ampe sejauh ini. Dia kira dia Zoro dari One Piece….bang, lu jalan liat pake mata, kan…? (...Oh my god, this is the first time I met someone who's completely lost. He thinks he's Zoro from One Piece...bro, did you even use your eyes while walking...?" Izuku mutters before he realizes he talks out loud and turns towards Eijirou, who simply smiles albeit confused at what he just said.

"…..you could find a bus stop near the station's exit," Izuku says in a dead tone, earning a surprised look from Kirishima. "And if you're wondering, there's the bus stop." Izuku points at the left side of Kirishima as he turns, noticing the sign that indicates the bus stop is there. Kirishima has the decency to look sheepish before grinning at Izuku gratefully.

"Thanks, bro. You save my bacon." Kirishima says. "Oh, sorry, how rude of me. I'm Eijirou Kirishima."

"N-nice to meet you, I'm Izuku Midoriya…" Izuku says. "So….why do you look for a bus station?"

"Well, I was hoping I could find a place to eat before I could partake in UA's entrance exam," Kirishima says before he perks up. "Oh, by the way, are you planning to take the exam as well? With all the training cleaning the entire beach, and all."

"Umm, yeah…" Izuku is always has been a terrible liar, either in his current life or his past life. Every time he opens his mouth, he can't help but tell the truth, and every time he tries to lie, it is so bad people can only give him a deadpan stare.

"Cool! I hope I'll see you there during the entrance exam! I hope you'll pass, bro!" Kirishima excitedly said before he walked away. Izuku merely stares at the boy in silence, wondering what kind of change will occur because of this small interaction. Given that simply remembering his past causes this much impact on the timeline, he shudders at the future aftermath of butterfly effects.

"Oh, my…..oh, my… GOODNESS!" Izuku yelps when he hears the familiar voice and turns around to see that same hulking blonde man from his room's poster, All Might, Japan's number 1 hero. "You did it! You clean the entire beach, right before the entrance exam as well!"

"A-All Might, y-yeah, I did…" Izuku says nervously as he lets out a somewhat tired smile. All Might simply laughs before patting his shoulder proudly, then pulls out his phone, showing a picture of Izuku All Might took pre-training.

"Yes, you did! You truly surprised me, my boy! Look at you! This is you 10 months ago! There have been ups and downs, but you push through! And here's the result of all of your hard work! You have not only become a suitable vessel for One for All, but you also exceed my expectations!" All Might laughs as Izuku can't help but feel somewhat embarrassed. He once laughed at the scene when the anime was aired, but now that he's the one experiencing the whole thing, he feels like it's no longer something funny.

"All Might….do I….do I deserve this? I feel like I'm cheating." Izuku says. "You…did all of this for me, I feel blessed. But…"

"Young Midoriya, this is the result of your hard work. Don't feel bad for earning something you have deserved! I suggest you not cry because you're crying for the wrong reason!" All Might says as he wipes off Izuku's tears using a handkerchief he pulls out of his pocket. "Anyways, it's time! I was once told 'Something that you receive because you are lucky and something that you receive because you are recognized are different in essence' I suggest you take it by heart because this power, is what you earned through all of your hard work."

"Y-yeah," Izuku replies before his face turns to dread, finally remembering the particular moment that had become one of the early BnHA memes. All Might plucks his hair off and hands it to him.

"Eat this!" All Might exclaims in a dead serious tone as Izuku stares at the hair in a deadpan manner.

"…..why?" Izuku can't help but let out a whine. Why does he have to suffer this? Is this some sort of cosmic joke for a reincarnated, specifically him, the one who becomes the main character of the fiction he used to read?

"To gain my power, you must consume my DNA for the transfer to work!" All Might exclaims.

"…..Are you sure that you didn't do this just because you once had to go through the same process?" Izuku asks in a deadpan manner as All Might look away and cough loudly.

"I have no idea what you're talking about, Young Midoriya!" All Might exclaims.

"….liar." Izuku takes the hair before squinting his face in disgust. "….All Might, please tell you that at least, you have water to help me swallow this?"

"Of course!" All Might exclaims as he pulls out a water bottle from under his jacket and offers to Izuku. Izuku gulps before putting the hair into his mouth and opens the bottle before pouring it into his mouth, swallowing everything.

"Blergh! I am not going through this ever again!" Izuku says as All Might stifles his chuckles.

"W-well, young Midoriya, the good news is that you only need to do it once." All Might says as Izuku lets out a sigh, holding his throat.

"Okay, so now-!" Izuku pauses as his vision starts to turn blurry, his legs feel like jelly, and his body is losing control. "Wha-!?" Immediately, Izuku falls as the last thing Izuku hears and sees before falling unconscious is All Might panicking and holding him before his face hits the ground.

"Young Midoriya!"

?

"Urrrgh…" Izuku groans as he opens his eyes. The moment he saw what was in front of him, his eyes shot wide open out of shock. The familiar world displayed through anime and manga, the black void filled with purple light floating around the sky, 9 thrones in a room, creating a circle, each throne was seated by a person.

The first person is a sickly man with messy white hair, wearing a casual long-sleeved shirt and a pair of trousers with a pair of black and white shoes. The second person reminds Izuku of Katsuki Bakugou, except his hair is red and there's a scar on his face, with a pair of bulky-looking gauntlets (Nevermind, this part also made him look like Bakugou, no wonder everyone theorized that he's related to Bakugou), a black long-sleeved shirt under a green vest, a pair of green trousers, and a pair of black combat boots.

The third person has a similar outfit as the second person with the difference being the absence of the gauntlet and shorter sleeves. The man has long grey hair tied in a spiky ponytail with a black bandanna around his head. The fourth person is a man with short white hair with two scar-like cracks from the left side of his forehead down to his chin. He wears long-sleeved white clothes covered by a tattered dark green jacket, a pair of long white pants with knee guards, and a belt.

The fifth person is a bulky bald man wearing dark leather clothes, a pair of gold goggles, and a bandolier with a lack of shirt underneath his leather jacket. The sixth person is a black-haired man wearing a collared red jacket that reminds him of a certain pro-hero (Best Jeanist), black trousers, a pair of hiking boots, and sports tape wrapping on his wrist. The seventh person is a tall woman with long black hair styled in a half-up-half-down bun, wearing a high-collared, dark sleeveless body suit with a pair of yellow gloves and white boots, a belt around her waist, a white long cape buttoned on her shoulder and a short one attached to the belt reaching her knees {Edna would have aneurysm if she saw her hero costume). The last person is nothing but a yellow silhouette that reminds him of All Might in his skinny form.

"W-what?" The sickly white-haired man exclaims in shock, not expecting Izuku to pop out of nowhere.

"Who're you!?" The Bakugou-lookalike points his gauntlet at Izuku as he growls.

"Whoa, whoa, whoa, calm down everyone!" The only woman exclaims as she shields Izuku from others. "Let's not be rash! He's a kid!"

"A random kid suddenly pops into One for All?! I seriously doubt it!" The same man snarls as he continues to point his gauntlet at Izuku. Before things could escalate, the yellow silhouette suddenly stood up and placed his hands on Izuku's shoulder, not saying a word. Everyone immediately calms down as realization strikes them.

"You're…also wield One For All…" The sickly white-haired man says with wide eyes as Izuku nods while shrugs, still too shocked. "H-how is this possible? D-does One for All reach singularity?!"

"It's possible…I mean, we all remained dormant until suddenly the entire realm shook and everyone was transferred into this room." The black-haired man states. "But, that doesn't explain what is the trigger that causes this."

"We only know it was caused by the boy, and based on Eighth's silhouette acts, he's the Ninth and he just got it not long ago." The bald man points out.

"Is it possible that it's due to Ninth's quirk?" The grey-haired man asks as the Eighth's silhouette shakes his head while making a cross sign. "Okay, he's quirkless, so that's tossed out of the window." Before anyone could continue their discussion, Izuku winces in pain as he holds his head, flashes of anime scenes and manga panels playing in his mind. All of the people look a bit concerned at Izuku's sudden wince in pain, but they are also hit by images from Izuku's head. As the pain disappeared, Izuku looked up and looked at everyone, who either widened their eyes in shock, jaws dropped, disbelief written on their face, and giddiness.

Wait, what?

"Isekai…" The sick white-haired man mutters as he shakes in giddiness. "Ninth is an isekai'd person! Oh, my god! This is amazing! It's official!" The man rushes towards Izuku and holds his hand, stars in his eyes. "You're officially the coolest wielder of One for All."

Izuku blinks at him as two men with similar-looking outfits facepalm and groan, while the rest continue to stare at Izuku in shock.

'…..ah, bangke. Belum 1 hari dan pada udah tau….ini pasti rekor baru… (...ah, fuck. Not even a day and people already knew...this must be a new record...'

To be continued
