Chapter 37

'Why do I feel like I am extremely far away from Marineford for?' Ace wondered with a sigh as he took a closer look at Harry's 'stick', 'I wonder what type of weapon that is, I have never seen anyone that uses just a small stick for a weapon in my travels.'

"Hogwarts is a school for eleven year olds to seventeen year olds," Harry said finally causing Ace's thoughts to come to a stop, "At Hogwarts students learn how to control their magic...the full title of the school is Hogwarts School of Witchcraft and Wizardry."

Shocked silence echoed throughout the room as Harry's words slowly began to sink into Ace's mind, Ace's mind ran a mile a minute as he tried to understand just what had been told to him.

"M-Magic? Witchcraft? Wizardry?" Ace asked with a unconvinced look on his face, "Are you sure that you all have not just eaten a devil fruit and has mistaken its powers for this 'magic'?"

"I have no idea what a devil fruit is, and you are either born with magic or you are born without magic, it is that simple," Harry replied as he looked Ace straight in the eye.

"Prove it then, show me some of this magic," Ace replied unconvincingly as he raised a hand to rest on top of his orange hat, "If this magic stuff is really true then show me some proof."

"Thank Merlin that this happened while I am at school and not back at my aunt's and uncle's house during the summer," Harry muttered softly as for the first time since Ace's arrival Harry pointed his wand away from Ace and at a large open area of the room, "Expecto Patronum!"

Ace watched with unmasked wide eyes full of awe and amazement as a large white glowing stag jumped out from Harry's so called magical wand and trotted around the room with his head down low and its antlers ready for battle. After a few minutes had passed by and the stag had found no threat to Harry it gave him a small nuzzle before disappearing, to where Ace had no idea.

"That was amazing!" Ace cried out excitedly a few seconds later causing Harry to look at him with wide shocked eyes, "I have NEVER seen anything like that before and I have been to a LOT of different places! How did you do that? It should not be possible."

"It is magic," Harry replied simply with a shrug of his shoulder, "I can cast that spell because I think really hard on one happy memory."

"So...you say you can just do magic?" Ace asked with wide yet calculating eyes, "That...you can always do magic?"

"Eerr...yes, magic is a part of a person, it is always there even if we do not know it is there or if we do not use it at times," Harry replied slowly, not really understanding what Ace was going on about.

"So...when I get back to the battle...well war as its turning out to be...do you think I can use an attack like this magic?" Ace asked suddenly with a large grin on his face, "Do you think that if I just believe that I can do it and if I believe that there has been this really cool attack inside of me all the time like you and your magic do you think that I could use this really cool attack and save everyone?"

Harry blinked in shock and confusion as he looked into Ace's excited and hyper face, Harry gulped nervously as he found himself being pinned to the spot by hopeful and excited eyes. Gulping nervously unsure on what to do or even how Ace had suddenly jumped to the conclusion about a powerful attack that he could use to save people if he just believed Harry did not know.

"Errr...I do not know," Harry said softly, he was not willing to break Ace's sudden burst of hope, "I guess you could try but I am not sure..."

"I guess I could always try using one of my attacks in a different way, I could just go for it like Luffy does at times...I wonder if I could change one of my fire attacks slightly so I can try to hit more than one person at a time," Ace muttered softly as a thoughtful expression found its way to his face, "Thanks Harry! You have helped me a lot! Maybe fighting this battle and getting out of it alive with everyone will not be so hard, if I just believe in myself and think in a slightly different way."

"Err...it is alright, do not worry about it," Harry replied slowly as he looked at Ace dumb struck, "But I did not really he-"

"How can I thank you? Is there anything that I can do in return for all of your help?" Ace asked suddenly cutting Harry off, "Just name it and I will do my best to make it happen!"

"I-I do not need anything from you!" Harry cried out as he stared at Ace in shock, "Really, I hardly helped you, I do not even know what is going on here! You came up with all of this by yourself, we have not even found a way to get you back to where you came from and-"

"Stop being so modest Har, you helped me out a lot, I was about to be executed by the marines, if it was not for your help myself and a lot of other people would be dead," Ace said cutting Harry's ramblings off, "So name it and if I can it is yours, if not I will just get my pops to help me out!"

"I...I really do not need anything, really, everything is alright," Harry replied as he tried to convince the orange hat wearing male, "I do not need anything from you or want anything from you. I am just...errr...happy that I have somehow managed to help you out."

Silence echoed between the pair as Ace stared into Harry's emerald green eyes with a look that clearly said he would not take no for an answer. Harry gulped nervously as he did his best to return the long stare while his grip around his wand tightened and his heart pounded like a big brass drum. A few seconds later a sudden large smile appeared on Ace's face confusing Harry.

"I got it! I know just what to give you as a thank you gift!" Ace cried out happily as he turned and reached into one of the pockets of his black shorts, "Let me just get it out, I found the thing while travelling around a few years ago, a strange woman gave it to me, said that I was to look after it until I meet up with the true owner of the item which then I would give the true owner the item and to me you fit the strange woman's description of the true owner with being from a weird faraway place, having long black hair, bright emerald eyes and having a stick like weapon!"

Deciding that it was safer to just nod his head instead of giving a verbal reply Harry watched silently as Ace let out a cry of victory and removed his hand from his black shorts pocket only to pull out a strange item. Harry could not quiet see the strange object in Ace's hand as the large males large hand was hiding the object. Seeing the smaller male's unhidden curiosity Ace shot Harry a large grin and held out the object, which turned out to be a simple necklace, and allowed it to hang from his fingers while Harry looked at it closely.

Looking at the strange necklace closely Harry found that the necklace itself was made up of a strong leather thick black cord that held a strange looking pendent. The pendent was a thick yet delicate looking wooden cat, to Harry it looked as if someone had spent hours and hours sitting still and carving the cat pendent out of a single block of wood.

"It is...amazing," Harry gasped out as he leant forwards to take a closer look at the wooden pendent, "I have never seen anything like it, it looks so delicate yet at the same time so strong...why did this strange person said you should give it to be for anyway?"

"No idea but you helped me out big time, and I want to give you something to thank you and so I will give you this," Ace replied with a shrug, "And before you start again remember that it is yours to begin with so if you cannot accept that I am giving you a thank you very much for helping me out gift then just think of it as I am returning to you an item that I have borrowed from you for a very long time."

'Well if he does not know anything about the war and he has no idea about who Dumbledore and Voldemort is and he has no knowledge of magic at all I guess it should be safe, I mean how can Ace, a muggle, cast an evil and dark spell on the necklace' Harry wondered as he gazed closer at the beautiful necklace in Ace's hands 'I guess to be on the safe side I could always ask Seto or Grandma or Granddad or even Professor Flitwick to look it over for any dark spells...'

"Here, let me help as you out as your hands are full," Ace said suddenly surprising Harry.

Before Harry could react Ace pulled himself up off of the sofa with a heavy grunt as his injured body made its displeasure known loud and clear. With a gulp and emerald eyes trying not to find themselves glued to the other males chest Harry watched as Ace pulled himself up to his full height of six foot one, the same height as Harry's beloved Seto give or take a few inches.
