Well I couldn't wait for posting this, since I did accept the challenge. Just saying that I am probably going to update this story only once a month or so, just to make sure I have plenty of time to write the next chapter and hoping I won't get writers block on this one due to stress about school and stuff. Luckily I only have about less than a half year to go.

Chapter 1

Harry sighed as he stared up to the sky from his spot high up in a tree. Dudley and his friends had been 'Harry hunting' again. They eventually had chased him up into this tree. Dudley as well as his group of friends hadn't been able to climb up into the tree after him.

They had stood under need the tree for hours, until they had had enough and had gone back home. Harry hadn't been really in the mood to get out of the tree again. If he went back home his uncle would probably punish him for being late.

There was also the point that it was Dudley's birthday tomorrow and he wasn't really looking forward to it. His aunt and uncle never took him with them when they went on a birthday trip with their son. Dudley's friend, Pier, always was invited to go with them.

They always went to do something fun. They would go to an amusement park or see a movie in the bios. This year they were planning to go to the zoo. As every year his aunt and uncle would probably take him to Mrs. Figg's, so she could have an eye on him.

It wasn't like Mrs. Figg was a bad person, rather she was very nice, but she was also a little bit too obsessed with cats. She had like a dozen cats roaming her house and every time he was forced to stay with her she would go on and on about every cat she had ever owned.

Harry had had enough of that so this year he just wanted to do what he liked. So he had decided to just stay outside for the night and the next day too. He then would try to get back inside the house, hopefully without too much trouble. He would probably get a beating, but if he would go home now he would get punished anyway. He rather wanted it later.

A sudden scream ran through the air, causing Harry to immediately sit up and looking alert around him. A girl came running into view. There was a broken chain attached to an iron plate on her chest. The girl was a ghost, Harry immediately recognized.

He had seen ghosts before. When he had been younger he had made the mistake to point out a ghost in trouble to his uncle. His uncle hadn't been able to see the ghost and had slapped him in the face for being freaky and being so in public too.

Ever since then Harry had been able to tell the difference between the dead and the living. The funny thing was he had made more friends with the dead then with the living.

The frightened girl suddenly turned around as a huge monster came into sight. It was probably the thing that had made the girl run in fright. Harry jumped out of the tree as the monster was about to swipe a huge claw at the girl.

Suddenly in a blur a man in around his twenties appeared in the front of them and blocked the claw with a sword. Harry looked at the man confused.

The man was wearing Japanese styled black clothing with white clothing under need. The sword he had in his hand was a Japanese Katana. The man had as unruly black hair as he had and also wore glasses.

Taking his eyes of the man he looked the monster over. It was a huge canine like monster. Its body was covered with black fur with a purplish glow to it. It had a bony white mask where its face should be and there was a gaping hole right through its chest. Harry was surprised it was even moving.

"Run, the both of you!" the man shouted.

Both Harry and the girl hesitated at first, but then Harry decided to take up to the advice the man had given them and ran, pulling the girl with him. They hadn't run far when suddenly the monster had moved in front of them. Harry looked around and could see the man seemed to be confused at the beast speed.

The girl screamed again as the huge and monstrous canine swiped with his claw at her again. The man was suddenly in front of them again, only this time he hadn't been able to block the swipe with his sword. He was thrown back and into them instead. The impact made both him and the girl tumble down.

"Mr.!" Harry said alarmed as he sat back up and saw the huge claw marks on the man's chest.

He was bleeding heavily from that wound too.

"Don't worry about me. It's that Hollow you should be worried about." The man said through gritted teeth as he was trying to bite the pain away.

"But, you're the only one that can protect us from that monster. You have too." Harry said, a little bit panicky.

"No, that's not exactly true. You can save us as well, if you accept my gift, that is." The man replied.

"What? I can?" Harry asked confused.

"Yes, you can. I can give you the strength to fight that Hollow as an equal. All you have to do is pierce your chest with this Zanpakuto." The man started, holding out the Katana towards him.

"Wait a minute. You want me to pierce a sword through my chest? Wouldn't that kill me?" Harry asked perplexed.

"No, it would not. This isn't a normal sword. It can't kill the living. What it can do when a living person is pierced with it is transfer my Shinigami powers over to you. This would be only temporarily, but it would be enough to take down that one Hollow." The man answered.

The Hollow roared in annoyance and was preparing to attack again. Harry looked at it hesitantly, but then turned around back to the man with a resolute look on his face.

"I'll do it. I'll take up your offer." Harry said.

The man nodded and on the moment the Hollow was about to attack he plunged his sword through Harry's chest. Right when that happened Harry felt an energy charging him up from the inside. He started to feel immensely powerful.

As the Hollow swiped his claw down at them that claw suddenly fell down with a thud as it was cut clean off. The man felt really surprised as he wasn't only completely drained from his powers, but the boy in front of him was holding a huge sword that was really way too big for the kid to be able to handle. The sword was about as big as he himself, yet the kid had been able to swing it down at the Hollow and then swing it back over his shoulder.

The Hollow growled menacely at Harry in anger. It then started to lunge for Harry, only for it to be cut down completely in half by the kick ass sword that Harry swung down at it.

The man stared at Harry speechless. Harry had cut down the beast as if it was nothing, while he had having trouble keeping up with the foul beast. As the man looked more closely at Harry he noticed Harry had changed a little and not meaning he had gained a Shinigami garb and sword.

The tips of Harry's hair had turned a bright orange. Harry turned back to the man and grinned.

"That was cool." Harry said.

"Glad you think so, but I didn't think you would actually take all of my powers." The man said.

"Wait, I took all of your powers? I didn't mean it, sir. I'm sorry." Harry said spitefully.

"It is okay, you don't have to apologize and my name is James, not sir." James replied.

"Well, I feel like I should apologize." Harry said, looking down.

"If it makes you feel better there is one thing you could do for me." James said.

"And that is?" Harry asked curiously.

"You ready to move on?" James asked the girl.

The girl nodded gleefully. James turned back to Harry.

"Put the back of your swords handle on the girls forehead. That should make it able for her to move on to the Soul Society." James explained.

"Like this?" Harry asked and did what him was told.

A Kanji appeared on the girls forehead when he removed his sword again. She then lighted up with a light bluish light and sank through the ground, a peaceful look on her face. Harry then turned back to James.

"I have a few questions, if I may ask them." Harry said.

"Sure, go ahead and ask as much questions as you like." James replied.

"First of, what exactly are you? I can tell you're not a living person, yet you are different than the other ghosts I have ever seen." Harry asked.

"You're right, I am dead. I am a Shinigami or in English a Soul Reaper. Shinigami overlooks the balance between the world of the living and the Soul Society, the place where the soul goes after a person dies. We make sure that every lingering spirit moves on by performing Konso on them. Konso is what you just did to that girl. But sometimes we are too late and the spirit morphs into a monster, known as a Hollow. That beast that you just destroyed was a Hollow." James explained.

"Ok, that explains a lot of my other questions as well. So, how am I able to turn off this Shinigami mode?" Harry asked.

"I don't know exactly. It isn't like Shinigami give their power to humans every other day." James answered truthfully.

"Great, just how…" just as Harry began to say that a swirl of energy surged around him, surprising him and James greatly.

As everything settled down again Harry was back to normal.

"Well, never mind then. Looks like I am back to normal." Harry said.

"You should go back home. It's getting late." James said.

"I don't want to." Harry replied, pouting slightly.

"Won't someone get worried about you? And besides you should get some rest after that fight." James said.

"No, my aunt and uncle don't give a damn about me and Dudley just loves to hunt me down. I probably would be punished for getting home late." Harry replied.

"Well, I think I can fix that little problem for you." James said, grinning like mad.

I hope you all liked it and please review. ^-^
