Ch. 12 Aftermath, Returns, Training, and Origin of One for All

After recovering from the injuries Izuku, Ochcako, and Eri said farewell to Gunhead and Gran Torino as their hero names.

The three went back to school there were some amazing stories to tell and some changes. Everyone was talking about their internships. Corazon and Shanks were with their dads doing a very weird and stupid adventure in Luffy's body to remove a laser implanted by Mushroom Alien Overlords (May make an omake), Katakiri was with his Grandmother Big Mama, Angel, Viper, Oliva, and Erza were interning for Boa Hancock, and Mune was also interning for the Beast Pirates since his dad is the first mate and weaponsmith for the Beast Pirates "Hades Forged" Mifune Nobunga (Dog dog fruit Model Cerberus) , Stone was interning for the Revolution Army led by Fleet Admiral/Supreme Commander "Aokiji" Kuzan and Commander in Chiefs Monkey D. Dragon, and advisors Monkey D. Garp, and Sengoku, with Admiral Ryokugyu, Admiral Coby, Admiral Fujitora and Chief of Staff Dragon Fist Sabo.

"And then I was like all right you pirate surrender the Sun Pirates have the high ground. They were like 'we're not pirates'. And I answered with,'well you have fishlike appearance and you're a criminal on the seas', right Asui?" Tiger said

"So, let me get this straight. Achilles' new recruits to the Beast Pirates used an extremely rare Devil Fruit the Original paramecia might I add and TURN IT INTO A FREAKING PIE?!" Shanks asked/yelled

"Pretty much yeah and Eri made the pie too isn't that right?" Izuku stated

"Yes, sir! Papa!" Eri said as she did a salute.

"Hey, guys let's not forget our very own Worst Generation members!" Kaminari yelled

"Yeah! Our very own Ryuma, Kaido, Ochako, Izuku, Tenya, and Shoto fought the Hero Killer and Endeavor saved them." the class said except the pirate kids.

"LIES...HOGWASH...BASELESS SLANDER!" Mune yelled as his honor said to reveal the truth.

"It's okay Mune I know how much you value honor and truth and besides I'm giving everyone in Class 1-A subscription to the World Economic Newspaper anyway," Kaido stated

"Fine if I hear any more of these lies, I'm throwing Mineta OUT OF THE WINDOW!" Mune yelled which Mineta responded with.

"WHY ME?!" Mineta asked/yelled

"You dishonor yourself for just being a pervert," Mune replied.

"Is it my fault that this class has some beautiful ladies!" Mineta tries to hold an argument.

"You saying those words backed up my claim," Mune stated as Aiziwa enter the class.

Skipping Tenya's speech and right on today's training.

Time skip to the training location everyone wearing their costumes except for Tenya's which is in repair.

"HA HA HA! HI FOR I'M HERE! It's been a while right kids today is Rescue Training so keep damages to the minimum. All right so take your positions" All Might said.

The same positions as in the manga

Sero thought he is first but when he saw Izuku jumping like Bakugo covered in electricity (One for All) and using Tremor at small bursts resulting Izuku in first place with Sero in second on his knees crying. All might whisper to Izuku and ask Izuku to talk later.

After that Ryuma, Corazon, Katakiri, Kaido, and Shanks all made to the finish line in order.

Then Mune, Viper, Angel, Stone, Erza, Tiger and Oliva came to the finish line in order.

After that Katakiri's Future Sight haki kicks in and saw that Mineta made a hole in the wall to peek at the girls again but had his eye poked so he decided to write a note to the girls and may add a date proposal to Mina since she is cute... when Katakiri thought of that he blushed

Later Mineta tried to "investigate" the hole, again while the entire locker room except for Katakiri into attack positions as Mineta into the hole Jiro's earphone jack got him in the eye.

"That pervert I can't believe he did it again!" Toru said

"I can't believe Katakiri was right in his note!" Mina said

"Oooohh, Note? Katakiri? Explained!" Toru asked

"Well, Katakiri gave me this note warning me and predicted what will happen just now," Mina said

"And he may offer a date..." Mina said as she blushed.

"Awesome! You got a date!" Toru exclaims

"Good job," Jirou said as Mina blushed even more.

"Well, let's plug this hole and finish changing our clothes," Momo said.

Meanwhile, at the same time in the girl's locker room, Mina told the girls about the letter and starting to plug up the hole.

Afterward, Izuku went to the teachers' breakroom but secretly followed by Kaido

"Lock the door." All Might said as Izuku close the door but not before Kaido turns into the wind and hid in the room.

Skipping the rules of One for All but the end results with Izuku understanding the quirk and said it is like a devil fruit.

"But Izuku you should know that One for All was born from the darkness it originated from a quirk called All for One you see 200 years ago when quirks starting to pop up the line between humans and "monsters" blurred," All Might explain as an image of quirkless humans and quirked humans were on different sides.

"And one man who gained the power to steal and give quirks he forced his brother to have a stockpiling quirk which combines with the power to pass down quirks in transforms into One for All. This man took over Japan he was a monster, and no one was able to beat him." All Might said.

"That's not true my Great grandfather defeated him" Kaido stated which scares All Might and Izuku since they didn't notice him in the room.

"Wait what do you mean?!" All Might and Izuku asked

"Izuku remember the story my dad told everyone about Captain Lor D. Harlock of the Acadia (Pluton's second name)" Kaido asked as an image of Captain Harlock and the Arcadia

"Yeah, but why don't you tell the story," Izuku said

"Well 200 years ago around the time quirks popped up and the Bermuda Triangle Gate permanently fused to this world. That started the first battle between Pirates and Villains you see this All for One you speak of already conquered Japan and saw pirates as a threat, so he decided to attack the first pirate he meets...heh heh that was his first mistake. You see when the two clashed the end results was All for One found almost dying on his knees and to add insult to injury Lor D. Harlock was quirkless, no devil fruit just haki." Kaido stated as a picture of a young AFO fighting Harlock and the end result in AFO on his knees with Harlock triumph over AFO.

"No way why I haven't heard of this?!" All Might asked since All for One was tough to beat.

"It's because All for One feared my Great Grandfather because he was quirkless and the name D. struck fear to his very core. When Harlock died All for One thought it was the end...He was wrong. 60 years ago, All for One fought the Rocks/Locks Pirates and was defeated at the time it was their era, Garp fought the Rocks and was known as Hero of the Marines. Then 20 years later since the "Rocks/Locks" lost their captain, "Gold Lion" Shiki and All for One teamed up and tried to, asked Izuku's Grandfather Gol D. Roger to become their right-hand man to let them use one of the three ancient weapons he found. Legend has it, it was ancient weapon Uranus. Roger refused their offer and the Battle of Edd War resulted in half of Shiki's fleet sunk, Shiki's retreat and All for One's many injuries from Roger's blade. When the Great Pirate Era began lots of very powerful pirates and marines took up the call at the execution like Crocodile, Gecko Moria, Mihawk, Shanks, Buggy, Smoker, Doflamingo, and Dragon." Kaido finished explaining.

"No way I never knew that All for One feared, pirates or that he was defeated three times before me." All Might said as the thought of AFO being defeated in his prime over and over.

"It wasn't just pirates. Kaido didn't you said that he feared the Will of D.?" Izuku asked which peaked All Might's curious thoughts.

"Will of D.?" All Might asked

"The Will of D. it went by many names the Spirit of D., Demon, Death, and the Enemy of God," Kaido explains.

"Whoa, if All for One had troubles with those from the D. clan then imagine One for All's user as a D." All Might explained (All Might know that the Straw Hat Grand Fleet Top Commanders knows of his secret since One for All is like a DF)

"He may be strong but...I know that I could beat him like my grandfather and Kaido's ancestor." Izuku declared with a smile.

"...Thanks, kids that cheered me up..." All Might said (same thoughts in the manga)

Skipping Aiziwa's speech about Summer Break with the results of everyone going to work hard for it.

Meanwhile in a dark room in an undisclosed location.

"I can't believe that bloodline is out in the world. That man makes my blood boiled. If only I am not in this wretched state, I would have killed him." All for One said.

"I know but there is nothing I can do to heal you faster. If only you obtained a Super healing quirk or something like that." said the doctor.

"Heh...Regardless Tomura will become the next "me" and nothing will get in his or my way." All for One declared.

"But sir, don't you remembered Gol D. Roger, he BEAT you and you had back up and outnumbered him. I'm afraid you won't be able to defeat or kill the new user of One for All since he's..." as soon as the doctor said that.

"IT WAS DIFFERENT BACK THEN and besides at this point, only a supernova-like explosion could kill me even in this weaken state and besides...how powerful is this Gol D. Izuku" All for One said with an evil smile

"..." both in silence

"Uh sir I think it's Portgas D. Izuku or Izuku D. Midoriya." the doctor refuted

"Whatever." All for One rolled his eyes(?)

To Be Continued…

Omake: Inside Luffy Story part 1

During the week of Interning for the Straw Hats near a trash bin.

"Man one last bag and I can eat that meat...hmmm...Meat..." Luffy said as a Space ship in shape of a purple mushroom appeared as light covered Luffy.

"Oooh...Bright light!" Luffy exclaimed as he floated to the ship.

"Oh, No! Mushroom alien overlords!" Luffy yelled

"Silence! Human and hold still," Princess Shroob (Younger).

As machines sounds were made the night turns into day and Luffy was dropped from the ship.

"Huh? Ouch! Hey! Quit it! AAAAHHHHHHHHHHHH!" Luffy yelled as he fell down.

"Ouch! Huh? Okay? How I got here? And why I am I in a garbage bin it's actually comfortable a bit," Luffy said

Luffy went into his house.

"LUFFY! YOU MISSED DINNER!" Nami yelled

"Hey, Dad you missed dinner! And you smelled," Shanks said as he pinched his nose.

"I'm sorry it's just that I was kidnapped by aliens and they did something to me!" Luffy yelled dramatically.

"Like what?" Nami asked

"I dunno? Aaaa...aaaa...AAAACCCCHHHHHHEEEEEWWWWWW!" As Luffy sneezed he shot out lasers from his EYES?! Which hit part of the house.

"We're going to get a doctor," Shanks said as he called Law.

"Umm... hello? Mr. Law?... Yes, it's Shanks...No no one got hurt...Look my dad just shot out lasers from his eyes...no I'm joking can we see you tomorrow?... Really! Thanks!" Shanks ended the called and decided to help his mom to hold down Luffy from sneezing.

Omake Part 1 ended

I'll be doing omakes sometimes for now on.
