Ouja's rebirth Chapter 3 I will take alternate timelines for 500
After a nice lunch of homemade curry Harry asked Yui what some of those words that Yui and Shiro said meant so she told him what each word means in Japanese.
When they made it back to where they left Shiro he was just coming to after being knocked out for a hour. "Who used a final vent on me?" Shiro groaned out as he got up off the ground only to find Yui looking at him with her right eye twitching. 'Shit I am so dead!' Thought Shiro, as he back away from his sister. "What was that about a final vent hitting you nii-chan?" She asked in a sickly sweet voice that promises pain if he answered wrong, luckily for Shiro, he was save by Harry asking what's a final vent was getting both of there attention.
"It seem that we have some explaining to do Imouto" Said Shiro trying to get Yui to forget about his final vent comment. "I guess your right nii-chan." She said but gave him a look that clearly said that he was are not off the hook. "You see Harry both Shiro nii-chan and I were what you call a muggle born wizard and witch." said Yui, "What do you mean by were?" Asked Harry, confused "Well, one day Yui and I were drawing a variety of different pictures when we accidentally used all our magic and brought our drawings to life and made copies of ourselves in the mirror that was in the room at the time. Because of that, I became a Squib from the lost of that much magic and Yui, she literally dropped dead." Said Shiro.
"I panicked as I tried get Yui to wake up when her mirror double said she could save Yui and keep her a live but it would only last till Yui turned twenty, so I agreed. Yui was awake again but the power her copy used had started a fire and took our parents life's. After that we were separate, Yui went to live with our father's sister and I was taken by are mother's sister and her husband to America. You can imagine are enthusiasm at that idea." He said the last part dripping with sarcasm.
He took a deep breath before continuing his tale. "In America, I became a scientific genius and with the help of my mirror double was able to figure out how to draw magic from the surrounding areas and made the advent decks." He said as he took a bronze case with a picture of a gold bird on it out of his pocket "This Harry, is a advent deck. One of the fifteen that I have in my possession, I made them to save Yui by drawing magic in to the deck it can create a suite of armor for the user. Here, let me give a demonstration." Just as he finished saying that he took the bronze deck in his left hand and thrust out his arm, just then a gold belt materialized around his waist that had a hollow slot in the centre for the deck.
With a cry of 'Henshin'! Shiro inserted the deck into the belt, a strange noise unlike anything Harry had heard before sounded. Just as it end three golden images appeared on both side and in front of him and started covering him then a flash of gold light. Gone was Shiro Kanzaki and in his places was a man in a gold and dark bronze color armor model after a phoenix his shoulders guards resembled golden wings. The helmet look some what like the ruffled feathers of the back of a birds head the armor had a royal and intimidating look to it. This, was Kamen Rider Odin.
"This, Harry, is what a Kamen Rider is. Impressing is it not?" Harry heard Shiro ask him. "That was so cool can you teach me how to do that?!" Asked a excited Harry. "Maybe" Said Shiro "Now were was I? Ah, now I remember." He said as he took the deck out and the armor shatters in to golden glass and falls away "After the decks were made I knew that I had to find riders fast to save Yui. So my mirror double gave me an idea if I was in Mirror World I could find them much faster. I used the first prototype I made to fuse myself and my copy together so I could move freely throughout Mirror World." He said.
"So I started searching for those that would fight to the end and kill to be the winner and get the prize of one wish." Shiro said "But a man named Hideyuki Kagawa found the notebook that contain my blueprints for the advent decks and my plans so he duplicated my work making the alternative decks to stop the war." He said.
And so the tale went on for hours, in the end Ryuki was mortally wounded while protecting a little girl. Knight died after wining the war and just shortly after he used the wish to save his fiancé Eri's life. To say Harry was in to the story would be a understatement, he was entranced by it. The heroes, the villains, he loved every moment of it! His favorite was Asakura, the only word he could think of to describe him was a word he heard a tourist say 'wicked awesome'.
In the end Harry told his new friends about his life and what he remember. When he was done his new friends had looks of disgust on their faces, he was about to asks what was wrong when he was swept up in to a hug by Yui. "Oh how could those horrible people do that to you?!" She asked with tears in her eyes. "Harry, how would you like to be a part of our family?" Asked Shiro. "You mean it?" Harry asked Shiro just nodded his head as Harry smiled and started to hug Yui back as hard as he could. Shiro could not help but feel that he made the right decision.
