Chapter 1: All It Takes Is One Small Change In Fate!

It was peaceful in the town of Morioh, it's been three month since Kira Yoshikag'se Death and Jotaro Kujo and Joseph Joestar depart from Morioh. Josuke Higashikata was well with everything returning to normal and enjoying the day with his close friend Koichi Hirose who was with his girlfriend Yukako Yamagishi, they were at a cafe enjoying a drink. Not too far from them was Rohan Kishibe working on his latest volume of his manga. Everything looked like it was going to be perfect.

Save for one thing, where was Okuyasu Nijimura? Well he was at the graveyard in Morioh, more specifically at his deceased brother's grave Keicho Nijimura. Sometimes Okuyasu would come and visit his brother's grave sometime to let him know how he was doing, sometimes to just stand there and look at the tombstone in silence, and even bring his father or flowers.

He was heard for the silence today, after everything that has happened with Kira, Okuyasu was reflecting on the battle. He never thought about it, but he cheated death, twice even. Sure most people avoid close calls, but he dodged death twice, first was with RHCP and the second was when Kira blow a hole in his side.

"Ha, you never know how lucky you are until you think about it. Right bro?" Okuyasu said to the tombstone.

He was only alive because of Josuke, he know that if it wasn't for Josuke he be dead. Yeah he save Josuke life by taking the bomb for him, but for RHCP he had the guy right where he wanted, he did! But he let himself got played for a fool, and if he was doing it by himself, he would be done for.

"You know, I have one of probably the most dangerous Stands in the world, it doesn't really help that I can't use it properly. You always told me to use my head and think for myself, I never truly took what you said to heart. I miss you Bro, I hope you got to see mom even if it was just once." He said in soft tombstone looking at sky. "It's been pretty peaceful, I hope you meet Reimi, she really nice and pretty cute, she would have been my type if she was still alive. And Shigechi he was a pretty cool guy, if it wasn't for him we never have got Kira. Oh! Dad been doing better, I still haven't found a way to turn him back yet, but he is getting smarter and he even learning more words!" He said with a smile.

He then sighs and takes a knee in front of the tombstone, he put a hand on it and then clenches it a bit as a few tears fall from his eyes.

"I can't tell sometime, if I'm strong or weak. I have a powerful Stand but a weak mind. Not unlike you, your mind was sharp and even though your Stand wasn't that much, your where stronger than me. I wanted to be just like you, I wanted to be as strong as you, but I'm not sure if I'll ever be. I don't want the people and friends in my life to be taken away from people like or even worse than Kira, or the rat bastard DIO. I want to be able to protect what I have now, even though I'm an idiot I do it." He said with a serious tone in his voice and he got back up. "I'll see ya around, love ya and hope you can rest bro." Was all he said as he walked away.

Fate works in mysterious ways, we can never tell what can happen next. Even if we can see the future! Fate remains a mystery to us all! Some say that we are slaves to fate, but some don't believe that and make the impossible possible and defy fate! All it takes is one event that changes everything forever.

Once Okuyasu was done with his semi sulking/self pumping at his brother's grave, he left to get some Black Tea, he was almost out at the house and needed to get some more, he saw Josuke hanging out with Koichi and Yukako, he smiled, He was glad after the hell they been put through that they could smile without a care in the world.

He wanted to join them but he needed the Black Tea plus he didn't want his father to freak out for him being gone for so long without him letting him know he was alright.

He took one more look at his friends and walk off, he thought Koichi was lucky, well as lucky as one can be when a girl is obsessed with you and kidnaps you and then tried to kill you. But after that she cool down and they look to be really happy, something Okuyasu wish he had, he wasn't one that caught the ladies eyes, with him hanging out with Josuke so much. The Joestar got all the girl after him, but of course the Josuke was too shy to make any real moves on a girl that caught his eye.

"It looks like some people have more luck than others." He sighed a bit.

He never thought about much, but it still bug me a bit playing third wheel to those two. It was never fun being the third wheel, but he was glad for his friend. But at times felt lonely, he was glad to have friends, but he felt lonely in a different way at a subconscious level he wanted more than a friend. But he never thought about too much because it hurt his head. He made it the to store found the Black Tea and grab it, after that he paid for it and left for home.

He was walking, and saw it was getting late, he was almost home and on his way he smell something, it smells like something was burning, he saw smoke and his heart sank when he saw it.

He ran as fast as he could, he saw fire as he closes the distance he saw his house, was on fire!

"Dad!" He shout in concerned.

He ran to the house as possible, he even scrape away space to close the distance. When he made he was horrified to his house was a blaze!

"Fu-Fuck, Dad! Dad!" He shouted in worry.

Not even given it a second thought he rush in smashing through the doors! He check the kitchen first where Stray Cat hissed and meowed in fear, he grabbed the planet and then rush up stairs but before he could get to the top step a flaming beam fall and block his path.

"Fuck! Dad! Dad can you hear me!?" He shouted again.

He didn't have time to find another path so he moves the flaming beam with The Hand and continue to search for his father. He checked every room, he checks his room and see nothing but he grab photo of him and Keicho as kids. And then his brother's room and still nothing, meanwhile the fire grow stronger and more flaming debris started falling, he then heard the familiar squeal of his mutated father.

"Dad!" He then rush to where the squeal came from.

When he made it, he saw his father being held a chain, and trying to get away from someone holding the chain, they flame cover them so Okuyasu could only make a feminine silhouette. But he was enraged by this and was ready to attack them

"I don't know or give a damn who you are, but you better release my dad or-" He didn't get to finish as he was hit in the right side by something fast making blood burst out.

He cough up blood as his dad only squeal louder, and as Okuyasu world got blurry he falls to the falls to the floor, he then saw the figure sprout wings and soak through roof with his father, faster than he has ever seen in his life.

"D-Dad… n-no." He said as he pointlessly reach out.

He saw the photo of his hold family before everything turned bad, he grabbed it and clenched it as tears pour from his eyes down his face. He holds Stray Cat closer as the fire looked like it was going to consume him that or he'll be crushed by falling debris, or maybe blood-loss will get to him first.

"Not like this…I'm not going out…like this…I promise whoever you are…I'll find you…and make you pay!" He shouted with all his strength and then his world went black.

Sometime later, Okuyasu woke up and shot up as he frantically look around, he was on the front lawn of his now burned down house. His wound was healed and Stray Cat was next to him.

Next to him was Josuke and Koichi, they were glad that Okuyasu was alive. Once Josuke saw the fire he panic and rush in using Crazy Diamond to get through and when he saw him, he was bleeding out and getting burned, but Josuke was able to save him. As for his house the flames where too strong so he had to leave before it fall on top of them.

"What the hell happened?" Okuyasu asked as he rubbed his head.

"Your house was on fire, I saw it and rush to help. When I got there you where on the floor bleeding out. What happened to you?" He said not sure what happened.

"I don't remember, I was on my way home and-" He widened his eyes as he remembered what had happened with his father. "Jo-Josuke, my dad… wa-was he in the house." He asked nervously.

"N-No, I couldn't find him. And with the Flesh Bud still fuse with his body, I doubt the fire killed him." He said as it was true, he couldn't find Mr. Nijimura.

"I…I see, so I wasn't dreaming… that really happened." He said grimly as he clenched his fist.

"Okuyasu, what happened?" Josuke asked again with a serious tone.

Okuyasu get up and then walks up to the ashes of his house, he picked them up with one hand as some of the ashes fall through fingers.

"I don't know who they are, but the set my house on fire and kidnapped my dad. For who knows what, I don't know. But I know that their going to pay for what they have done to me!" He said in anger as he clenched the ashes.

After that the trio got in touch with Jotaro, Okuyasu explained what had happened and was pleading Jotaro to find his father, Jotaro said he would do all he could, and he did after doing some long and intense investigating, he learn rumors of a creatures screaming late at night like it was crying. The only catch was that it was in an area of Japan that had a school, so Okuyasu would need to transfer to a school called Kuoh Academy. Jotaro already made arrangements so that Okuyasu didn't have to worry about being homeless.

He was set on doing this, he needed to do this. He already lost his mother and his brother, he was not going to lose his father too, he already lost and abandoned him once, he wasn't going to do that a second time!

After a week of getting everything ready for Okuyasu transfer, Okuyasu was sporting new clothing, he was wearing black tank top, over it was a dark blue leather jacket with white and silver metal detail, on the back of the jacket it said "Bad Company" in gold, he wear jet black pants that had golden detail, and white shoes, he had an old style travel bag with all the stuff he would need.

He was waiting for a boat that was going to take him took Kuoh Academy, Josuke, Koichi, Yukako, even Rohan were there to see him off. Josuke and Koichi wear his friends so it was normal for them to be there, but Yukako and even Rohan were a surprise, for Yukako it was the fact the he was Koichi's friend but also thanks to his brother for shooting her she was able to meet Koichi. For Rohan well he wasn't a complete dick, that and he was able to find new material because of Heaven Door.

"I know how important this is to you Okuyasu, but be careful." Josuke said concerned.

"I will Josuke, this is going to be a long journey. And I'm not sure where or who would kidnap my dad, or even why, but I need to find him." He said firmly.

"I know. But don't forget, you know nothing about these people, so be careful." He warned putting a hand on his shoulder.

Okuyasu remember back to that moment, the silhouette red eyes and wings of darkness.

"They don't know me either, but I'll be careful." He said in a serious tone.

"I don't know what to say, but I hope you find your dad Okuyasu." Koichi said honestly.

"That means a lot Koichi, thanks." Okuyasu said smiling softly as the sun was setting behind him.

"I didn't know your brother, and I don't know your father. But I know the feeling of loving someone, so I hope you found your loved one." Yukako said softly and kindly.

That surprise Okuyasu, but he didn't say anything and just continue to smile at her.

"Hmmph, I hope you don't expect me to say anything nice or heart-warming. The likely of someone like you surviving are slim." Rohan said harshly.

That piss off Josuke and made Koichi frown from the rude comment Rohan made.

"I don't expect you to say stuff like that Rohan, I was expecting a dick comment like that." Okuyasu said back still smiling.

That shock Rohan, who then sighed and rubbed his head and after sometime he look back at Okuyasu.

"I stand by what I said, but if your Koichi friend. I'm sure even someone like you can manage to survive all by yourself. So don't good making me regret praising you because you get finish off by some no-name nobody!" He said dramatically.

"Well what do you know, the Great Rohan Kishibe saying something nice, and now I heard it all." Okuyasu joked making Rohan "hmph" and turn the other way. "I'll try not to disappoint you too bad." He said smiling.

"You better." Rohan said firmly.

"Don't forget that Jotaro and everyone else got your back buddy, where partners in crime now." Josuke said smiling.

"Of course, I not get stupid!" He said smiling back.

The two shared a laugh and after that it was quiet, Okuyasu turn and look at the sunset. He wasn't sure if he was going to find his father, or why he was taken, or what the hell that thing was that took him, but he wasn't going to let this go without a fight.

The boat appeared and on it was Jotaro, he look at Okuyasu, he nodded back and turn his friends for a final goodbye and walk up the ram.

"Once you make it, I look more into what we're dealing with. Because whatever the thing was you saw took your father was not human." Jotaro said to Okuyasu.

"That's all the more reason I need to get him back." He said seriously.

And so the boat was off, Okuyasu just look to the horizon with steeled nerves and a hardened spirit. He's going to find his dad, even if he has to fight his way through Stand Users, monsters, and even the devil itself.

Little did he know the devil was going to closer and different then he could ever imagine in his hold life.

There you have it, now I personally love how The Devil's Diamond is set up and in no way am I trying to rip it off. I just wanted to try my turn at this and see where it goes, let me know what your favor part of the chapter was.

How do you think Okuyasu will feel about Kuoh Academy? How do you think he'll react to Devils and Rias? How do you think Okuyasu will feel about the Perverted Trio? And who should be in his harem? Review me yours answer, and as always thanks for your support!

Peace!
