Author's Note: Laziness took over me, I'm skipping over the meetings of Pearl and Hades, and straight to Beacon Days. In return I will explain H and P's bios.
Pearl Blackmist -
Age: 17
Gender: Female
Semblance: Hyperaction (Pearl can react to any situation coming towards her, a semi-passive Semblance. It is constantly active, but Pearl can shut it off to preserve Aura and her stamina. It also costs glucose and calories to use for extended amounts of time. Once active, Pearl can automatically dodge, counterattack, and get stronger quickly in a fight. She can also lock people's Aura if they are too powerful of a person to beat normally.)
Hades Blackmist -
Age: 17
Gender: Male
Semblance: Realm of Shadows (A Semi-Passive Semblance, just like Pearl. Hades can activate and deactivate it at will, but it is active whenever he isn't trying to keep it inactive [like when he's asleep]. With this Semblance, anything related to the concept of darkness [whether it be shadows, Grimm, or anything else], are able to be controlled by him. He can Shadow Travel, he can take control of Grimm that Salem doesn't control, and he can heal people with this darkness.)
Hyperion - 03
-RWBY VERSE, THE KINGDOM OF VALE, BEACON ACADEMY-
Ozpin was curious. He felt that the "R" of Team HPRN was hiding something, even if subconsciously. He closed his eyes, sitting in his office chair.
He thought to himself, before the old Headmaster's eyes snapped wide open. Realization hit him like a truck. He knew who young Ryutensei was… or rather, used to be. He quickly called for Glynda.
The moment the golden-haired Assistant Headmistress came into his office, he gave her his task. "Bring Ryuuto to me. I have to speak with him."
Glynda nodded, but asked a question. "Ozpin, if you don't mind me asking, why do you want to speak with him?"
"I'm going to ask him a few questions, see if a theory I have about him is right." Ozpin smiled, giving her a cryptic answer. Glynda nodded, and left.
-RWBY VERSE, THE KINGDOM OF VALE, BEACON ACADEMY, HPRN DORMS-
Ryuuto awkwardly smiled at his teammates, who've been glaring at him for the last hour or so. "So… how've you all been?"
Pearl and Hades' glares intensified, causing Ryuuto to flinch, as Nero shook his head. Ryuuto then heard a knock on the dorm's door, and got up quickly. "I'm… going to open this door now!-" He rushed to it and opened said door, surprised to see Professor Goodwitch. "Professor! What are you doing here?"
"Ozpin wants to talk to you." She said bluntly, before walking away. Ryuuto looked at Nero, who shrugged, and sighed. He then followed Glynda to Ozpin's office.
Ryuuto quickly arrived in said office, where the old Headmaster sat. "Professor Ozpin. You called?"
"Ryuuto, yes, welcome. Take a seat." Ozpin smiled and gestured for him to sit down. Ryuuto did so quickly. "Question, what's your favourite fairy tail?"
"...what." Ryuuto blinked. This is not what he expected Ozpin to ask.
"Fairy tails. Stories from your childhood." Ozpin pressed, with Glynda narrowing her eyes. She had a feeling about what Ozpin was trying to do, but she didn't know why Ozpin was trying to bring a student (former assassin or not, he was still just that) into the Guardians business.
"Well… there's the Tale of the Two Brothers, I liked that one. Oh, and the Warring Cousins was interesting." Ryuuto answered after some time.
"How about the Story of the Seasons?" Ozpin raised an eyebrow.
"The one where 4 young women helped a grouchy old man out, and got immense power from him in return?" Ryuuto hummed. "Yeah, I've heard that one a few times before."
"What if I told you that the Story of the Seasons and the Warring Cousins were true?"
Ryuuto was floored. "You're joking, right? This is just a prank?"
Glynda spoke up for the first time. "I'm afraid not. Everything Ozpin is saying to you is the truth. We haven't encountered nor heard about an incarnation of the Cousins in a long, long time, due to how they only come back every one-hundred years."
"Until today." Ozpin smirked. "I believe that you, Ryuuto, are the incarnation of Peace."
"You're saying I'm some God reborn." Ryuuto skeptically said. Ozpin nodded.
"More or less." Ryuuto looked slightly to the side, seeing a hard-light depiction of General Ironwood. "While normally I'd be against bringing a Student into our business, Ozpin has a point. You look almost like a carbon copy of the first Incarnation of Peace."
"My mother named me after him…" Ryuuto muttered, looking down. He then got up and looked Ozpin in the eye. "If you're telling the truth, why don't I remember anything?"
"Most likely your Reincarnation process supressing your memories until you can handle them. I believe you can now. All we need to do is unlock your Aura." Ryuuto blinked.
"But my Aura's already unlocked."
"Exactly. But if we do it again, I'm sure your memories, and by proxy your powers; will be unlocked." Ozpin stood. "Are you willing to go with this?"
"...If you're telling the truth, then I want to help you… help Remnant." Ryuuto firmly said. "Do it."
Ozpin smiled, before getting serious and putting his hand out. "For it is in determination that we achieve success. Through this, we become a paragon of light and humanity to rise above her. Infinite in death and unbound by time, I release your soul, and by my power, condemn thee."
At first, Ryuuto felt nothing. Then his head started to pang, pain and headaches overwhelming him as hundreds upon thousands of years of memories pouring into his mind. His eyes widened as he found a gate in his mind and pushed it open.
Mistake.
Unfathomable, immeasurable pain wracked his body as he fell to his hands and knees. He tried to keep himself from screaming, breathing heavily, but then he couldn't hold it back any longer.
He screamed a blood-curdling, demonic scream before falling unconcious. Ozpin and Glynda rushed over to Ryuuto, with Ozpin's eyes narrowing. "He's alive, but barely. Perhaps he wasn't as ready as I first assumed… Get him to the medical bay."
"We have our Peace, but where is War?"
