A few days go by and Hisashi Midoriya aka the hero known as Chronos Rose walks into Izuku's room at the hospital and sees that his son was dressed in a pair of jeans, a t-shirt, and his signature red shoes.

"Are you ready?" Hisashi asks, leaning against the door.

Izuku nodded before he frowned.

"You said you were hit by Priestess's Quirk, right?" the Ninth Successor asked his father.

Hisashi nodded.

"Who were you in your past life?" Izuku asked.

Hisashi smiled sadly.

"I'll keep that to myself, Izuku," Hisashi said. "All that you need to know is that I was someone you did not want to cross."

Izuku nodded in understanding before he grabbed a bag that his mother had given him just a few days before and then followed his father out of the room and to five vans that were waiting outside the hero hospital. They stopped In the lobby, where Izuku found his friends waiting for him and was surprised to see Mashirao in a wheelchair... with no tail.

"Wh-What the hell?" Izuku muttered. "What happened?"

His friends were a little more than surprised to hear that he talked without a stutter and with more confidence. He held himself higher as well, his eyes were moving around as well as if he was looking for any hidden enemies.

"Good morning everyone," Hisashi said smiling. "Are you all ready?"

They all nodded, and without making a sound, before exiting the building and entered the vans to go to UA.

The next three hours were spent in silence, as the five students just stared out of the windows watching the cars go by and ignoring their parents asking questions about the USJ. Memories they saw were flashing through their minds and it wouldn't stop. It was as if they were watching a movie on repeat several times, but this movie was trying to break them, make them lose their minds from the death, the hell they went through. They could also feel new power rushing through them granting them immense strength. Izuku closed his eyes and he was brought back to the world he saw right before he woke back up.

Izuku's Mind

Izuku found himself on a hill once more. Thousands of blades littered the ground sticking up as if they were gravestones for warriors long dead. He looked up and saw that the sky was cloudy with the sun shining through, he could feel the sun's rays on his skin and he closed his eyes as if he was relishing in the silence this place brought him. As if he could stay here and think for all of eternity.

"Hey Ninth!" a woman's voice spoke out.

Izuku opened his eyes and he saw a beautiful woman who had black hair and was wearing a hero suit. She had a beauty mark on her face as well. She had a voluptuous frame and her grey eyes showed her confidence and strength befitting of a hero. Her black hair was in a ponytail and its shiny color complimented her fair skin tone. Her hero suit consisted of a black sleeveless bodysuit that hugged her figure well with a high collar. She had on yellow elbow-length gloves and white knee-high boots. Around her waist was a belt with an angular golden buckle, a small cape attached around the back which went down to her knees, and over her shoulders was a longer cape, buttoned to the shoulders of her bodysuit.

"Welcome back to your mind, number nine," the woman said smiling. "How ya doing?"

"Who are you?" Izuku asked, his eyes narrowing and several swords came out of the ground and hovered around the two. "Where did you come from?"

The woman pointed up to the sky and Izuku saw the slap of rock he saw last time.

"As for who I am," the woman began. "My name is Nana Shimura and I'm the predecessor of All Might as well as his teacher."

The swords went back to their original position and Izuku looked at the 7th user of One for All.

"How?" he asked. "How am I seeing you in my mind?"

Izuku appeared on the rock that was floating above their heads.

"Because, Nine," a man with white hair shadowing his eyes and wearing a white shirt and pants. "We were affected by that woman's Meta-Power just like you."

Izuku's eyes widened in surprise, but before he could ask what he meant, the Ninth Successor began to fade away.

"It appears that you are waking up," the man said. "We will be talking again soon, Nine. For now, master your powers and then we can talk about One for All."

The real world

"-Zuku. Izuku we're here," Inko, a woman with green hair and eyes, told her son. "Are you okay?"

"Y-Yeah," Izuku replied. "I just had an odd dream."

"What did you see?" Hisashi asked.

"A world of blades," was all Izuku said before the teen got out of the van and headed to the entrance of the university known as UA.

"A world of blades..." Hisashi muttered. "Interesting."

Hisashi left the van and followed his son, and his friends, into the university. When they arrived, Midnight and Aizawa were there waiting for them.

"Finally," Aizawa said. "You arrived. The others in the new dorms that we set up a day after the attack at the USJ. Follow us there and you will give an explanation of what happened. Understood?"

"Yes sensei," Momo Yaoyorozu said with a confidence that wasn't seen in her prior to being hit with Priestess's quirk.

Midnight turned to look at the parents and told them, "They will explain after we have found out what they now remember. Okay?"

The parents nodded, but Midnight could tell they didn't like what she said.

The five students walked, with the exception of Mashirao who was still in his wheelchair, behind the teachers followed by Hisashi who had a thoughtful expression on his face.

Not long later, they arrived at the new dorms where their friends were already waiting for them and waiting for an explanation of what happened to them. The silence was deafening until one of them mustered up the courage to ask what exactly happened at the USJ.

"What the hell happened nerd?" Bakugo asked. "We were told by Thirteen that you were forced to remember past fucking life. That can't happen, reincarnation does not exist. So what the fuck happened!?"

"Bakugo!" shouted Hisashi.

Bakugo immediately went silent.

"Sorry Uncle," Bakugo muttered.

Hisashi sighed. "I understand you want answers, that you all want answers, but give these five a chance to explain without demanding answers. Now as for your statement regarding reincarnation... I'll say this once, it does exist as I have had the memories of a man known as Kiritsugu Emiya for the past 20 years. A man who was an assassin and who would take no prisoners. While his methods were... not exactly heroic, he was still considered a hero by Kami herself and was sent into the cycle of reincarnation."

Izuku then began chuckling, getting odd looks from his classmates and his father. Ochako, on the other hand, was frowning at Hisashi.

"Like father, like son," Izuku said through his chuckles. "Both of them were killers in their past life and even were reborn into the same family in this life!"

"What do you mean?" Shoto asked, his eyes narrowed.

"I was a man named Shirou in my past life," Izuku told them. This got Hisashi to smile widely as both Momo and Ochako smiled happily at the information they just received. "A third-rate magus who had only one specialty. Projection."

At that word, several swords appeared behind Izuku and everyone backed up.

"He made a deal with a being known as Alaya in that life," Izuku told them. "The Will of Humanity was another name for it... I don't know if Alaya even has a gender... Anyways, he made a deal with Alaya that was basically this: he would work for her to make a world where no one had to cry. A stupid thing to do as he would be summoned to whatever human-made disaster and be forced to kill over and over again for all time."

"W-What?" Kirishima asked, shocked. "Why would he do something like that?"

"Because he had taken a dream from the man who adopted him after saving him from a hell that would shape his life," Izuku informed them. "The man who adopted him was Kiritsugu Emiya."

"So my son in this life was the son I adopted in the previous life," Hisashi said with a small smile. "I'm happy to have a second chance."

'Guess I was wrong,' Todoroki thought. 'Izuku Midoriya is not the son of All Might...'

"What about Momo-chan?" Mineta asked. "I bet she had a big rack in her past life!"

A tick mark appeared on Momo's forehead and, with a reinforced kick, sent Mineta through the wall.

"Stay down you damned perv!" Momo shouted at Mineta, a fire appeared in her eyes and she glared at the hole in the wall. "If you say something like that again, I will convince Izuku to puncture you full of swords and leave your body to the sharks!"

She then turned back to the class and her teachers with a smile on her face and her eyes closed. She didn't see the sweet drops nor did she see the look on Izuku's face when realization hit him.

'She's...' Izuku couldn't even finish that thought when he was brought back to the real world by Momo saying, "I was a woman named Rin Tohsaka a... good friend of Emiya-kun."

She blushed at the memories she saw before shaking her head and continuing.

"She was a mage, and a master, in the 5th Holy Grail War that took place in Fuyuki, Japan in the year of 2006," Momo explained.

"What's a mage? And what do you mean by Master?" Denki asked.

"A mage is someone who can use what is basically magic," Izuku explained. "But it's called Magecraft to the ones who use it. Think of Magecraft as anything that can be done by science but in a quicker time frame. In fact, my powers are a type of Magecraft called Projection. It's actually very basic and one of the very few he could use without any problems."

"As for a master," Momo began. "There was a war that Shirou and Rin both played a part in. The war was called the Holy Grail War. In this war, there were seven mages who summoned seven servants. These servants were each a different class based on their legend."

"Legend?" asked Mina.

"King Arthur would be a Saber-class," Ochako told them with a small smile. "Hercules would be a Berserker class."

"The other five classes are Archer, Lancer, Assassin, Rider, and Caster," Momo continued on. "And the Mage who summons a servant from one of the seven classes is called a Master. I was the master of Archer in the Fifth Grail War while Shirou was the master of Saber."

"Why was the war fought?" Aizawa asked.

"For an object that could grant any wish," Ochako answered. "The Holy Grail was a wish-granting device that could grant any wish the winner of the war wants. Whether it be immortality or money. It can grant you anything you ask of it."

"So I could ask for a harem of hot babes with huge oppai!?"

Hisashi stopped Momo from sending him through another wall with a reinforced kick.

'That was a quick recovery,' was the thought that ran through everyone's head.

"Ever heard of the saying, 'Be careful what you wish for?'" Ochako asked. The teachers and students nodded. "That goes double with the Grail. Let's take Mineta's wish for example. If he wishes for a harem, then the Grail will twist that wish and corrupt it. So instead of it being a harem of women, it might be men or even... well... you know."

Mineta's face went white as the images he came up with in his head.

"That is what the grail does," Ochako continued. "Even if it's a wish granted for someone with a pure heart, it will be corrupted. And it will be disastrous in some way."

That silenced the room for a good ten minutes as what they said settled in everyone's mind.

"I think we should continue on with the introductions," Aizawa said at last. "Mashirao. You're next."

Mashirao Ojiro sighed.

"I don't understand much of the life I saw," the blond teen said. "But I do know that I... no, that he was trained by a powerful and dangerous warrior. A woman named Scathach. She had a spear, a powerful weapon in her hand."

Mashirao placed a hand on his head as if he was in pain.

"I won't be telling you guys much," Mashirao stated. "I was a man named Setanta, known later by Cu Chulainn, the Hound of Ireland. It means "Culann's Savage Dog" in Gaelic. He was the demigod son of Lugh and a mortal woman named Deichtine, who was the younger sister of a king named Conchobar mac Nessa. Cu Chulainn was trained by a powerful sorceress named Scathach and it was with her that he learned all he could do when he faced off against an unnamed Archer in the 5th Holy Grail War."

"So we got a Demigod, a third-rate, and another Magus," Shoto commented. "Who are you two?"

He said that last sentence towards Ochako and Tooru. Ochako gave a small smile while Tooru looked at Shoto as if he was prey.

"In my past life-" Ochako began.

"I was known as the "Poison Girl", in history," Tooru said. "An assassin that would frequently get close to her targets as a lover or fiance. I killed hundreds of people ranging from kings to generals of armies. All in their sleeping quarters. No one suspected me. After all, who would suspect an innocent-looking woman to be the killer of their leaders?"

The young woman spoke softly, and when she finished, she looked away from her classmates and her teachers. She was afraid of what they would do, of what they would say, now that they know she is the reincarnation of an assassin who used poison to silently kill her victims.

Izuku scoffed and everyone looked at him.

"You haven't seen what I did, Tooru," Izuku told her. A scowl was on his face and it seemed to fill the air around them with a dangerous feeling. "You were not the one who killed entire armies on his own. Who killed, and killed, and killed just because he was ordered to by the will of humanity."

Izuku's hands were clenched tightly.

"I saw him take many, many, many lives after he died when he was framed for causing a war that he helped stop," Izuku told her. "He, and by extension me, has more blood on his hands than any one of us do. If anyone should just leave here, it's me."

"That's not what I saw, Deku-kun," Ochako said softly. Izuku looked into her eyes and he could have sworn that he saw something familiar in them. "I saw a man who was willing to do anything to save the world, including sacrificing his own happiness. I saw a man who faced himself in a world of unlimited blades and came out victorious. That is who you are, Archer. A Hero of Justice."

"Wh-Who are you?" Izuku asked, confused.

Ochako smiled and for a split second, her image was replaced with that of a European woman with blonde hair in a bun and emerald green eyes.

"I was a noble in another life," Ochako said, her brown eyes showing confidence and power the likes her classmates and the Pros in the room have never seen before. "You all know her story. For it is one of the most well-known legends in the world. Even if the legend was wrong about her gender."

"What do you mean?" Mineta asked. "What, were you an Amazonian queen with a big rack or something? Cause that would be really hot!"

Ochako's eye twitched.

"No," Ochako told him. "I was Artoria Pendragon, the King of Great Britain."

And the room went into complete silence. Everyone was too stunned to move, too shocked to say a word. That is until Bakugo spoke up.

"Sorry Uncle Hisashi," the explosion Quirk user said. "But I have to say it."

Hisashi sighed. "Go ahead. I'll let it slide this time."

Bakugo nodded, before he exclaimed, "WHAT THE ACTUAL FUCK!?"
