Raining Darkness
Prologue
Disclaimer: I do not own Harry Potter or Bleach. If I did I wouldn't be writing this.
Summary: What if Harry wasn't who everyone thought he was? What if he had been a shinigami captain once and the very first Vizard before Aizen began his experiments? What if he remembered everything? Pairings Harry x Yoruichi. Begins the summer before 3rd year.
Harry sighed as he washed the dishes from breakfast that morning. It was extremely hot this summer. The only thing he was glad about was for the moment his relatives were gone and wouldn't be back till later. Although he really wished that he could use his true power. 'I hate people thinking I'm just some weak kid that gets lucky all the time.' He growled inwardly. A figure that looked like a human but was covered in shadow and had a long cloak covering his features.
"This was your idea master. But at least part of my power is at your command when you choose to wield it again. But as you already know bankai is still out of your reach for now but you will eventually regain it as well as your other powers." The figure said standing right behind Harry and looking at him.
"I know that Yamigetsu. I don't know why but I get the feeling that I might need your power soon. Most likely this school year." Harry said turning and looking at the figure. "It's probably a good thing that normal witches and wizards can't see you since Dumbledore no doubt has people watching me." This got a nod from the figure.
"Master when are you going to do something about that thing attached to your soul?" Yamigetsu asked looking at Harry seriously.
"If I'm right and I need your powers this year then I'll do it then. After all if I'm right then I think I know what it is." Harry said looking at Yamigetsu who nodded. Harry finished washing the dishes and started on the rest of the chores, which took about two hours. "The Durselys are probly on their way back now we'll continue this discussion later Yamigetsu." Harry said getting a nod from the zanpakuto spirit that disappeared back into Harry's inner world.
True to Harry's prediction the Durselys pulled into the driveway and got out with a rather fat woman this woman was Marge. "Boy get out her and bring in Marge's bags NOW." Harry's uncle Vernon yelled loudly.
Harry sighed but went out and got the bags out of the trunk. He carried them in avoiding the dog. He thought about using a low level Bakudo to pin the dog and leave it there. But then figured that would just cause more problems. 'This life really sucks the only time it's good is when I'm at Hogwarts.' He thought to himself.
*Time skip that night*
Harry was in his room thinking when he heard a loud roar. 'A hollow here? What the hell is going on?' He thought then silently opened his window. 'Thankfully I've regained enough of my power to do this.' With that last thought he jumped out of the window and onto the air using his reiatsu to condense it into a solid platform. He then jumped off in the direction of the Hollow's Reiatsu. He was shocked when he saw an Adjuchas class Hollow. "Well now I'm shocked to see such a powerful Hollow here. I mean the only significant source of Reiatsu around here I'm aware of is my own and I've kept it below the level of a seated officer so what drew you?" He asked looking at the monster.
"Hahaha you really think your going to get an answer from me shinigami? Your stupider then you look but I'm sure you'll still be delicious." The Hollow said charging at him.
Harry just sighed and raised his right hand. "Hado 33 Soukatsuio." Harry said launching a ball of blue fire at the hollow's mask head on. The hollow howled in pain. Harry held his right hand out and a katana with a half moon guard appeared in his hand. "Your finished hollow." He said showing up in front of the hollow and cutting its mask in half. The hollow dissolved and Harry turned around just in time to see a Shinigami appear. One who was much younger in his past life. "Well now this is a surprise. How are you Bya-kun?" Harry said smirking at the look of annoyance on the man's face.
"I don't know who you are or how you know my name. But at the moment that's not important. What is important is how you have that and how you knew about the hollow." Byakuya said glaring at Harry.
"I'm not surprised that you don't remember me Bya-kun. After all it has been 100 years since we've seen each other. Also back then I looked much different." Harry said resting his sword on his shoulder and looking at Byakuya calmly. "My name now is Harry James Potter. But 100 years ago before I was killed my name was, Komari Raizen." Harry said looking at the captain whose eyes widened.
"That's not possible." Byakuya said drawing his sword.
"Don't be dense Bya-kun you can feel my Reiatsu. But if that's not enough proof for you allow me to show you my Shikai." Harry said holding his sword in front his face with his hand on the dull edge of his sword. "Devour the light Yamigetsu." Dark reiatsu then swirled around Harry and his blade. When it died down the sword had changed. It was now a long black and white katana with a circular guard and chain with a crescent moon hanging from the handle. Byakuya's eyes widened at this. "If your still not convinced I could show you my Zanpakuto's special ability." Harry said as black flame enveloped the blade.
Byakuya sheathed his sword knowing he couldn't defeat the former captain. Harry caused the flames to die down and sheathed his sword in the sheath that had appeared out of nowhere. "Lets go somewhere else where we can talk." Byakuya said getting a nod from Harry before using Shunpo. Harry followed him to an abandoned house. "Now then you have some explaining to do." Byakuya said looking at the reincarnation of the former captain.
"While then where do you want me to start Bya-kun?" Harry asked noticing Byakuya's eye twitch at the nickname.
"Why don't you start from when you died how did you die?" Byakuya asked.
Harry sighed then proceeded to tell him about finding out that Aizen was trying to make hybrids of Shinigami and Hollows and how he had confronted him. He told him about his battle and how he had underestimated him. After words Harry leaned back. "Now you know what happened." He said.
Byakuya had a thoughtful expression for a minute. "If what you say is true then this could cause problems. But Aizen hasn't shown himself to be a traitor in anyway at this time anyways." Byakuya said.
A/N: Ok I'm going to end it here. Yes this takes place before the Rukia rescue arc. This is even before Ichigo got his powers. Also Harry's zanpakuto is not related to Engetsu or Zangetsu. He does not have the Getsugatenshou.
