This is going to be a really cool idea that I wanted to do. Now that I am a fan of High School DXD I wanted to put my hands in making some stories. I got to that show was thanks to two stories: A Devil Diamond by Mugiwara N0 Luffy and Hero Academia by dinocam3. My only issue with High School DXD is Issei I just think he is not that great of a character. I liked him in A Devil Diamond because Josuke was a great person to be pair up with him to help out, but on his own he is not that great and kind of annoying.

This story is like this: It's a mashup of both stories with new content. Instead of Issei is Izuku and his best friend is Josuke Higashikata, while Izuku life is turn upside down by his new life Josuke learns about his powers and lineage. This is a story of friendship and love, since both these two are getting a large Harem. Who will have more girls at the end?

I got permission from dinocam3 to do this and A Devil Diamond is pretty much dead so I wanted to do something. Here is the main thing, I wont just copy and past both stories, they are both super different. In Hero Academia DXD pretty much is on season 2 of High School DXD while A Devil Diamond didn't even got to the ratting game. I want to my own spin, and I am planning to put some characters that will be interesting to see.

Some say that Diamonds are Unbreakable but lets see if they can hold up against the powers of demons and heroes.

The Earth was not a regular and simple planet. It was a bizarre and weird world. Ever since the appearance of quirks nothing was the same, these powers were called as miracle given by the gods while others called the next step of human evolution. During these years of adaption, the earth suffered something that happened during the pre-quirk era, meteorite that hit Earth pretty hard and even destroyed some areas but nothing major.

The main difference is now that 80% of the human race was now users of a power called Quirks, while the rest 20% was the minority and seemed as lower by the rest of society

''Not all men are created equal. This is something I learned a long time ago''

That phrase was said by a boy that had his whole reality retold in just a year.

At a Playground

A little boy with green haired was protecting a kid with chestnut hair. The boy with green haired was crying and shaking in fear.

''You´re being mean to him Kacchan.'' Said the boy named Izuku Midoriya.

''What are you saying?! We are just playing.'' Said an ash blonde boy named Katsuki Bakugo.

''if you don't stop hurting him...I will never forgive you!" Said Izuku.

The boys in front of him were some bullies that were picking up at another kid for some stupid reason. The leader of this group was Katsuki Bakugo, a very loud brat that was never the same once he awoke his quirk explosions and he received praises all the time.

''You really think I am going to listen to you.'' Said Bakugo with a smirk.

''Please.'' Said Izuku nervous.

''AAAAAH.'' Said Bakugo using his explosive to attack Izuku.

The boy soon got attacked by Bakugo and his toon lackies. He couldn't do anything since he didn't have any quirk. He was a meek child with no powers, he couldn't protect himself from that lunatic child.

''As if I would receive order from a deku!'' Said Bakugo ready to beat Izuku even more.

Before he could do another attack someone grabbed Bakugo arm.

''What?'' Asked Bakugo confused

''Stop hurting him.'' Said a tall kid with a weird haircut.

''Who are you?" Asked Bakugo now pissed.

''I hate bullies and you are one.'' Said the tall kid.

''Oh really! Who is going to stop me? You and your stupid hair?!'' Said Bakugo pissed.

The kid didn't like that and soon Bakugo for the first time was beaten by someone as the bigger kid tossed him to the side.

''aaaah!'' Said Bakugo being tossed to the side.

''Wow bakugo got overpowered.'' Said one of the lackies.

''Leave them alone!'' Said the bigger kid.

''I am not going to be bossed by someone else!'' Said Bakugo.

''Oh really?!'' Said Bakugo ready to attack.

Bakugo tried to scare the bigger kid with his explosion but that did little damage. The bigger kid had a lot more of stamina and strength and soon Bakugo felt being beaten for once, getting bruises and cuts.

''Argh!'' Said Bakugo in pain.

''Bakugo stop. He is too strong!' Said one of the lackies.

''You got lucky Deku! But I will be back!'' Said Bakugo running away.

Bakugo and the lackies run off in fear. Also the kid that was crying left because he was scared of the new kid, the only one in the area was Izuku since he was still in bad shape from the beatdown.

''These guys are nothing but trouble.'' Said the kid.

''Yes.'' Said Izuku nervous.

The bigger kid helped Izuku get up and the green haired kid was still crying.

''Stop crying. They are gone.'' Said the bigger kid.

''I am fine.'' Said Izuku.

''Are you hurt?'' Asked the kid

''No. But were you mad for what they said about your hair?" Asked Izuku.

''Yes, this hair means a lot for me. I don't care what people say to me. Insulting my hair is like insulting the things I like.'' Said the kid.

''I think your hair is pretty cool.'' Said Izuku.

''Thanks. So why were they picking on you?" Asked the kid.

''because I am quirkless. I can't defend myself.'' Said Izuku.

''So what I am also quirkless.'' Said the kid.

''Really?'' Asked Izuku in shock. He meet another quirkless person.

''People look down on us because of the lack of power. We can still be as competent as the rest of them.'' Said the kid.

''So what do you wanna be when you grown up?" Asked Izuku.

''I want to become a hero.'' Said the kid.

''Me too, do you think that people like us can become heroes?'' Asked Izuku

''Yes, if we work hard we can become heroes. Nowadays we can become anything.'' Said the kid.

Izuku felt a sense of inspiration. This kid was like nobody he ever before, he was strong and wasn't scared of Bakugo.

''What is your name?" Asked the kid.

''Izuku Midoriya.''

''My name is Josuke, Josuke Higashikata. If you want you can call me Jojo.'' Said Josuke.

This was the start of a powerful friendship. Izuku and Josuke would become best friends from that day on. They would talk about new heroes, new things and pretty much be good with each other. Nobody would beat these two for being quirkless, some would try with Izuku but then Josuke would appear, and they would regret it. Despite everything nothing would stop them for being heroes.

10 Years later

Izuku and Josuke were now in the same middle school, Aldera Junior High. Despite Josuke having the look of an 18 year old he was only 14 years old. According to the doctors it was genetics, but he didn't know who his father was, he lived with his mother and grandfather and had a regular happy life, while Izuku lived with his mother while his father had to be transferred to work outside of country to make a better life to his family.

The era of quirks was far more for Izuku. Specially, when All Might first appeared.

All Might, the Symbol of Peace. Whenever he arrived, the villain was capture and nobody was hurt. He would always appear with the widest grin on his face, his booming laughter echoing through the air no matter what kind of danger he plunged into

Izuku was in his school were he was sketching a crude drawing of All Might face into his notebook. He couldn't help it. Thinking about his idol always put him into a great mood.

''I wish I could see todays video of him taking out those bank robbers earlier today. I can't believe it that just happened a few blocks from here.'' Thought Izuku

As he was sketching on his notebook, he heard the bell of his school announcing that the classes were about to start soon. While he was doing this, he started mumbling a lot, a bad quality of his.

''Not only that, All Might actually teamed up with Ingenium for that! It will be the first time I would ever seen him be partnered with a speed quirk user. I can see how Ingenium stacks up against All Might in that depa…'' Said Izuku mumbling making people looking at him weird. Soon that was cut when someone shout ouw.

''HEY DEKU!'' Said a rash voice.

Bakugo now 14 years old haven't changed that much since he was a kid. He was just taller and a lot stronger since then.

''Stop with this mumbling shit!'' Scream Bakugo.

''Sorry Kacchan. I am working on it.'' Said Izuku a bit sad.

''And what that hell are you doing obsessing over the speed of All Might and Ingen whatever.'' Said Bakugo.

''Its Ingenium.'' Said Izuku in a lower voice.

''Did you just corrected me?' Asked Bakugo in a murderous tone.

''No.'' Said Izuku a bit sad.

The rest of the class started to mutter about this scene. They loved to look down on him.

''Here we go again with Midoriya.''

''I know Bakugo has a powerful quirk, but he is too hot head it.''

''Hey, better he be an ass to Midoriya than to us. At least he doesn't attack the rest of the class.''

''Honestly Midoriya doing this to compensate is very sad.''

Midoriya just look down sad. He knew he was quirkless and he is reminding of that every day on his life. At least he had a good life, some others quirkless people had very horrible life's because of their status. He was lucky to have a very carrying mother who loved him and a good friend.

''Why the fuck were you doing this crap?" Asked Bakugo now pissed.

''Well you know I like gather information.'' Said Izuku nervous.

''Dream on! You are just trying to compensate for your pathetic look. Your scrawny little ass couldn't even hope to catch up to them. I mean, have you seen yourself in Phys Ed? It's a disgrace you´re even competing against me, let alone all this…'' Said Bakugo humiliating Izuku but them his ramblings were stop by someone arriving at the class while opening the door in full force.

Bam!

The new arrival was a tall pre teen. He was almost the side of a senior in high school and he had a huge pompadour hairstyle. Despite the weird haircut nobody ever dare to messed up with him, Josuke was a nice guy and sometimes a bit shy but once he saw his friend in danger he would snap at the bully.

''Hey guys what was that all about?'' Asked Josuke all serious.

The other students look a bit nervous. They feared Bakugo, but they feared Josuke even more. Despite Bakugo having a super powerful quirk, Josuke had the physics of a superhuman, he was the strongest in the class despite being quirkless which made Bakugo super mad.

''Oh hey Josuke.''

''Hey there man. How are you doing?''

''Yes, what up.''

Josuke saw Izuku looking nervous and Bakugo nearby he knew what this meant.

''Were you all picking on Izuku again?'' Asked Josuke.

''No!''

''Yes, we were just talking about…All Might! Did you know he teamed up with a hero nearby?"

''Izuku is a cool guy.''

Josuke just scoff and look at the other kids.

''Stop pretending. You all are a bunch of liars.'' Said Josuke very serious.

The tall teen then went to see his best friend and the other kids just walk away. The difference was Izuku was a meek and shy boy, Josuke was a tall and very muscular one that could break someone nose within a few minutes.

''Bakugo beat it!'' Said Josuke.

The blonde hated Josuke as much he hated Izuku, he could never beat this guy despite him not having a quirk. That was making him go mad, but he knew that he would get rid of him this year.

''You are lucky that the freak likes you.'' Said Bakugo in a whisper.

''What did you say?!'' Said Josuke serious.

''Whatever, it was nothing about your hair.'' Said Bakugo leaving. After years of getting his ass beaten by Josuke he learned to leave his hair out of the insults.

Once Bakugo was gone Josuke went to check on Izuku.

''Are you ok there man?" Asked Josuke.

''Yes, thanks Jojo.'' Said Izuku

''Midoriya-san are you ok?' Asked a new person.

The two turn their head to see who was speaking. This was Milia Takamaki, one of the few girls who didn't appear to think of them in any negative light, and t he only girl who even bothered to talk to the two. Because of that, she was the only girl that they knew they could count to if something happen, and they felt good around them. She was very cute too, having shoulder length light ocean blue hair tied in a ponytail by a purple ribbon and deep purple eyes along with thick long black eyelashes. Over her eyes were a set of huge circular glasses, which made boys and girls alike view her as a cute meganekko (glasses girl), Her figure was slim and petite and she had a bust size that made most girls jealous and always made the two boys blush madly.

''I am fine Takamaki-san.' Said Izuku blushing.

''I told you to try to talk back. Don't be afraid of him anymore. This the last year of middle school, if UA hears that he is a bully they will kick him out.'' Said Josuke.

''Sorry.'' Said Izuku

''Josuke-kun is right. Bakugo depends so much in getting to UA, if they accept the likes of him then anyone can get in there.'' Said Millia.

''Yeah man we made that promise to get there. Me and Izuku will go there and we will become heroes.'' Said Josuke with an optimistic smile.

''This is so nice Josuke-kun.'' Said Millia with a smile

''Thanks guys.'' Said Izuku

The class soon started, Josuke and Millia went to their desk. While the teacher was talking Izuku was deep in his thought.

''It doesn't matter what Kacchan says. There is always a chance, this what Jojo always told me. There has a chance for me to become a hero!'' Thought him.

After class

Josuke and Midoriya started to walk in the streets and think of what to do next.

''So you wanna hit the coffee shop next?' Asked Josuke.

''No thanks.'' Said Izuku

''are you still sad about Bakugo?" Asked Josuke.

''I am not.'' Said Izuku but he wasn't doing a good job in hiding out.

''You need to start defending yourself. You can't let him step on you anymore.'' Said Josuke.

''Lucky for you to say. You are the strongest person I know, and this fills the spot for your lacky of a quirk.'' Said Izuku.

''Hey I got genes to help me.'' Said Josuke.

''I know that athletic I am not the strongest, but I can be a scientific hero, who works with analysis or…what I am even saying? Kacchan is right, I can't even lift a single weight on Phys Ed. How can I get to UA if I can't do that.'' Said Izuku all sad.

''Izuku stop talking crap like that!'' Said Josuke.

''Oh what? I might start to have a realistic look. You are gifted while I am nothing.'' Said Izuku.

''Hey don't you dare talk like that! You are the smartest person I know! I would still be in kindergarten if it weren't for you helping me out. Screw Bakugo racist point of view! You can become a hero and if they don't accept you then I will not go to UA.'' Said Josuke.

Izuku still couldn't believe that even after 10 years of friendship. Nobody outside of Millia or his mother would talk nice to him, but Josuke was different. He was someone that deeply care for their friendship and was always there for Izuku on his worst times.

''Why do you always help me out?" Asked Izuku in tears.

''You are my best friend. Nobody ever care to talk to me because I was huge and because of my hair. After that day you weren't scare of me. Besides I suck in making new friends, you are the only person that I can rely on if something bad happens.'' Said Josuke being sincere.

''Wow thanks Jojo.'' Said Izuku smiling.

''Hey let's find something to make you feel better.'' Said Josuke

''Like what?" Asked Izuku

While Josuke was thinking of something to cheer up his best friend, something was happening in the back.

''Look!'' Said a random citzen.

''All Might!'' Said another one.

The green haired teen froze at the announcement. Josuke just smile seeing that, he liked All Might but he wasn't his favorite Pro Hero. The two ran off to see where the number hero was. Several other people had done the same thing, most of them hoping to catch a glimpse of the Symbol of peace.

''Did we missed him?" Asked Josuke to a random person.

'He is over there!'' Said a man with weird things on his head.

The two soon saw All Might in all of his glory. Seeing that Juggernaut of Justice in person was something else. He was wearing his classic blue and red spandex, his cape blowing in the wind. Under his arm, there was some overly large and slightly deformed man, mostly likely due to his quirk, beaten unconscious. The boisterous laughter of the number one hero echoed through the air.

''Wow!'' Said Josuke impressed.

''So cool. I actually got to see him in person! It was amazing!'' Said Izuku going all fan boy mode.

''Are you ok there? Do you two like All Might?'' Said a new voice.

''He is All Might number so…'' Said Josuke to the person but he soon stopped talking once he saw how that person looked.

''Of course! All Might is amazing in every sense of the word! Ever since I was little, I always wanted to….'' Izuku explain but then he saw the new person.

The new person was a girl. He would froze up if was any girl, but this was different. She had cyan eyes and very long, flaming red hair, not to mention a voluptuous figure, which include breasts that a lot of girls would kill to have. She also wore the standard UA uniform. Izuku and Josuke blush upon seeing her, Josuke blush normally while Izuku was red as a pepper.

''Is something wrong?'' Asked the girl.

''Uh…aaaaaha!" Scream Izuku running off.

''What is wrong with him?" Asked girl.

''Sorry he has a stomach problem! I need to see if he doesn't crap his pants!'' Said Josuke giving the first excuse that came to his head.

The girl saw the toon middle school running off like two weirdos. She didn't know what just happened.

''What was that?" Asked her

With the two

Izuku was catching up his breath. He was sweating in nerve because he talked with such a beautiful girl talking to him.

''Izuku! What was that? You scream and run in front of her!'' Said Josuke.

''Sorry, I panic. I didn't know what to do! I thought she would laugh at me and continuing to talk, I never talk with other girls outside of mom and Takamaki-san so I didn't know what to say next and…'' Said Izuku going off in his rumblings and Josuke stop that with a smacking him in the face.

SMACK

''Pull yourself together man. You need to stop being shy and talk with some girls! We are getting to high school, you need to talk with some girls at some point.'' Said Josuke.

''Sorry, I know you want the best for me but I don't know how. You talk with girls all the time so how can you speak with them?'' Asked Izuku

''Hey, it's simple I just talk them like human beings. Try thinking of every girl as Millia, you can talk with her.'' Said Josuke.

''Its different. Takamaki-san I got used but talking with other girls is such a difficult task. I don't know Josuke, I don't know if I could even get a girlfriend in my life.'' Said Izuku.

''Hey at least you can try. I don't know how but I can teach you, but I am more of a guy who wants true love. If a girl has a heart broken, you can be a good shoulder to cry.'' Said Josuke offering to be Izuku wingman.

''I guess this could be something.'' Said Izuku kind likng this idea.

''Really, so you aren't going to date Millia?'' Asked Josuke.

''WHAT! NO TAKAMAKI-SAN IS MY FRIEND!'' Said Izuku in pure shock.

''Calm down man. Dodnt need to blow off my ear.'' Said Josuke.

''I am sorry.'' Said Izuku

''You are so humble. Its cleary that she likes you. Ask her out man.'' Said Josuke.

''I don't know how.'' Said Izuku all shy.

''He is so difficult.'' Thought Josuke.

Then the bus arrived. They saw the time and Josuke saw it was time.

'Hey, my buss is here. I need to get in or my mom will throw my games out.'' Said Josuke.

''Alright.'' Said Izuku.

''See yah tomorrow man.'' Said Josuke

''See you Jojo.'' Said Izuku

While Izuku was waiting for his bus he was thinking on what Josuke told him about Millia.

''Could she like me as a…boyfriend? No! She is my friend. I don't know if any girl could be attracted by me.'' Thought Izuku.

''Uh excuse me.'' Said a new voice.

Izuku looked to his side and saw a new girl talking to him. She was a raven-haired girl wearing a white, double breasted blazer with a high collar and a gold trim that reaches halfway down her thighs, its sleeves elbow-length and cut off by wide pale blue cuffs, a large pink bow at her neck, a dark blue long sleeved shirt with matching dress pants, white gloves and white boots. She was also wearing the uniform of Seiia Academy, an all girl hero school know around the country.

Of course seeing someone like that made poor Izuku blush and shake.

''Uh yes?" Asked Izuku.

''I am sorry are you ok?" Asked her.

''I am talking to another girl!'' Thought Izuku.

''Excuse me, I couldn't help to overhear you saying that you want to become a hero. Is that correct?' Asked the girl.

''Yeah, that's all I want.'' Sid Izuku.

''Well good, my name is Amano Yuuma, and…I think I can help you.'' Said her with a smile.

''Huh? How?'' Asked Izuku

''I know how to help people reach their true potentials. You just have to do me a few favors is all. Can we meet at Wookies after school hours tomorrow?" Asked Amano.

Izuku didn't know why but he felt a bad sensation in his stomach.

''Who is this girl and why do I have a bad feeling about this?" Asked him mentally.

''Do you understand me dear?" Asked Amano.

''Sure. What is the favor?" Asked him.

''Go on a date with me.'' Said Amano with a smile

Izuku just stood there frozen. A few minutes ago, he was mopping saying that he would never get a girlfriend in his life. And then out of nowhere a girl, a pretty one from a hero school appears saying that she wanted to go on a date with him. Sometimes the universe likes to have some pranks with you.

''What!'' Said Izuku in shock.

''Ok, I will see you tomorrow.'' Said Amano leaving Izuku with her phone number written in a napkin.

Izuku took the napkin and started typing the number in fast speed. He felt a sense of pride at the moment. He felt he would end up alone but now he got a date with a pretty girl. He felt so much joy in his life.

''I GOT A DATE!' Said him super loud.

At the bus

Josuke was playing a game at his phone and he was doing badly. He wanted to beat his highest score and have a sense of victory.

''Man, these levels keep getting ridiculous sometimes. Who the hell wants to buy that much armor?!' Asked Josuke seeing the adds for buying new equipment.'' Said Josuke.

As he was keep trying out to not buy this crap, he got a message from Izuku.

Buzz Buzz

Josuke soon clicked the message and saw Izuku mumbled crap all over the message.

´´Jojoyouwonteverbelivewhatjusthappenedtome….

´´Calm down man! Spaces! Tell me a very abridged version of what happened? ´´

´´I got a date! With a pretty girl.´´

Josuke soon saw that and got into shock mode.

''What!'' Said Josuke out loud in the bus. Izuku got a date before him.

At a small club in UA

''Izuku Midoriya and Josuke Higashikata from class C-3.'' Said the red haired girl from earlier.

The girl was talking in a room with a very gothic atmosphere. There were some couches surroudnign a small table which held a chess set in the middle and a desk table sitting at the end of the room. Sitting at the desk was the red-haired girl, who was reading some profiles about Izuku and Josuke. She was also in the presence of a black-haired girl, a petite white haired girl and a blonde boy.

''that's all the info I could get. It was easy because they are from my neighboring class.'' Said the boy.

''It says here that both are quirkless?'' Asked the black haired girl.

''Really? What about this Josuke? He looks way too beefy for someone quirkless.'' Said the red haired girl.

''Apparently Higashikata is gifted in the athletics. His grandfather is a captain in the police and has trained him since he was a kid in self defense and making him train.'' Said the boy.

''So he is already superhuman.'' Said the black-haired girl.

''Also they are best friends since they were kids. Nobody like to talk with them because they are quirkless. His classmates try to attack them but Josuke always protect Midoriya. One of them named Katsuki Bakugo always wanted to attack them but never gets the chance. The only person that talks with them is Takamaki-san.'' Said the blonde boy.

''What is this all about? Why are we looking at these two?" Asked the white haired girl.

''Even if both of them are quirkless, I could feel that there was something only about those two. I just couldn't put my finger on it.'' Said the red haired girl.

''You mean that both of them have Sacred Gear?'' Asked the white haired girl.

''Yes and no.'' Said the red haired girl.

''What do you mean bunchou?'' Asked the black haired girl.

''I mean one of them has definitely a secret Gear, but the other has something lurking inside of them. Is like something that not even I can make of it.'' Said the girl looking at a picture of Josuke.

The trio felt a bit nervous. If their boss didn't know what it was then they were scared.

''Do you want us to look into this?" Asked the black haired girl.

''No, I will look at this by myself. If something happen, I will contact you three.'' Said the red haired girl.

The trio just nod as they look at the file with focus and a bit of fear.

''Izuku Midoriya and Josuke Higashikata. What are you two hiding?" Asked the red-haired girl.

This is the set up for things to come. Izuku and Josuke have a good friendship and Jojo makes sure nobody messes with his best friend. Remember even before Crazy Diamond Josuke was crazily strong.

Here is something that I will take from A Devil Diamond. Koichi unfortunately will get the boot here. Izuku kind takes his role of his best friend and the person that will help him while he gets used to his new world after hearing about the stands and his lineage. I am also not going to fully have things 100% from that story, I will have some major elements but there are moments that drag on and I want to have things from High School DXD on the run. We will have things moving.

On the Hero Academia DXD its pretty obvious that Akeno and Asia were replaced by two characters. This won't happen here, lets just say we will get the best of both worlds here and you will be surprised on which boy the girls want to go towards.

I hope you all enjoy the first chapter. This will be a crazy story and I can't wait to show the power of stands, demons and quirks all around. This is going to be a super awesome story and let's keep showing that Diamonds will always be unbreakable.
