This is something that I wanted to try. I know I just started this story a month ago, but for some reason I am deeply invested in here. I finally found out the actual canon ending of what happen at the end of High School DxD, it was fine and I guess this is what most of the characters would do. Also, I read a one shot called ´´The Immortal King´´ and since that was one was abandoned I am going to implemented some ideas from there in here. If you look closely, you know what I am talking about. I am not going to spoil much of what I am going to do here, but let's see. Enjoy.
On the halls of Valhalla
A little young Valkyrie was running for her first day of training. She had small purple hair and looked like she had 10 years old, but she was over 1000. She was going to have her firt day of training with the head Valkyrie Brunhilde.
She soon see the beautifl long haired woman, with a gorgerous black and blue dress.
''You are late child.'' Said Brunhilde
''Sorry miss Brunhilde.'' Said the Valkyrie know as Mist.
Mist was the new Valkyrie in the area and she was going to receive direct training from the head Valkyrie herself.
''Alright, it's your first day so I could imagine this happening. Come with me.'' Said Brunhilde.
The two started to walk on the halls of Valhalla, possibly to the training grounds where all the warriors get their start.
''Have you studied all the weapons and spells from your training book?'' Asked Brunhilde.
''Yes, back to cover. I know old spells and the new ones.'' Said Mist.
''Good, I will see that later right now we are going to learn a bit of history.'' Said Brunhilde.
''What?! Aren't we going to train?" Asked Mist confused.
''Are you questioning me?' Asked Brunhilde with a serious face.
''No!'' Said Mist in horror.
''Good, now let's go.'' Said Brunhilde.
The two soon arrived a huge door that was about 100 meters tall. It was one of the largest room in the realm.
''Behold the hall of heroes.'' Said Brunhilde.
The place was a museum where objects and history of the greatest warriors and beings are preserved in here.
''Wow!'' Said Mist in amazement.
''Yes, the greatest beings in the whole multiverse tell their tales here. From Angels to simple humans, there are relics from so many wars that it would take me centuries to count all of them.'' Said Brunhilde.
The young Valkyrie saw all those relics and description of some of the greatest heroes of all time. She was going all fan girl all around.
''Fa Mulan, Jean d´Arc , Sun Wukong , Hercules…'' Said Mist listing a ton of heroes and other amazing peoples.
''You have great knowledge of these great men and women. It's truly amazing seeing these pieces.'' Said Brunhilde walking around.
The young Valkyrie was with stars in her eyes upon seeing some of the greatest weapon in the history of mankind. While walking around she see a hall with a name plastered on the top.
''What is that?' Asked Mist seeing the other section of the museum with had a huge name in big Greek letters.
´´Straw Hat/ DXD´´
''Oh that is the area reserved for two of the greatest heroes of all time and their teams.'' Said Brunhilde.
''Of whom are you referring too?'' Asked Mist
Brunhilde just had a smile and hold her right hand on her face, pretty much doing a dramatic phase.
''The Immortal Pirate King and the Red Dragon Emperor!'' Said Brunhilde with a smile.
The young Valkyrie had a look of shock in her face, it was almost like someone told her the meaning of life. She was now full fan girl mode.
''What! The Immortal Pirate King and the Red Dragon Emperor! The greatest fighters and protectors of the multiverse! You are telling me there is a section just based on them?" Asked Mist in super excitement mode.
''Yes, we have some relics, documents, videos and all kinds of things from the time that they saved the whole universe numerous ways. Do you wanna go there?" Asked Brunhilde.
''Uh…'' Said Mist nervous.
''lets go.'' Said Brunhilde grabbing Mist hand and dragging her to the section.
The Valkyrie open the doors and a bunch of relics are in there. Blueprints from the Thousand Sunny, some original pieces from Rias Gremory, one of Chopper Rubber Balls, a box of chocolate with an autograph from Koneko and numerous other items.
''Wow!'' Said Mist in full exicitmenet.
''Yes, impressive. This is regarded as one of the most precious and memorable places in the hall of heroes.'' Said Brunhilde.
The young Valkyrie was just mumbling a ton of stuff about each piece. However one thing caught her attention at 100%. An old straw hat being on display, that Straw Hat was knw all around the entire realms and the whole multiverse.
''Is that the real straw hat of the Immortal Pirate King?'' Asked Mist in shock.
''No, the real one is still with him. Only gods and others higher ups wore the real thing, we made this replica, and nobody knew the difference.'' Said Brunhilde in a whisper.
''Miss Brunhilde you seem very familiar with the Immortal Pirate King and the Red Dragon Emperor, did you meet them?"
The old Valkyrie just smile at that, her mind going on a nostalgic sense remembering those days centuries ago.
''To tell you the truth yes. I worked with them very closely, the Pirate King and his crew and the Red Dragon Emperor and his peerage. It was something that I never thought seeing in action, we thought we were going to die, and they come and do the impossible.'' Said Brunhilde remembering Luffy and Issei charging into action and ending a huge battle.
The young Valkyrie hears that and she felt like she was about to hear the most amazing thing she ever heard.
''Really! You saw them in action!?' Asked Mist.
''Yes, but to tell the truth they are more impressive while fighting. When they are off duty they are really difficult to handle, one of them wouldn't shut up about he was going to be just a regular Pirate King and the other kept shouting on how he was going to be the Harem King.'' Said Brunhilde remembering the numerous times that the two shout those words over and over again.
The young Valkyrie had a look of confusion in her face, she never imagined those two legendary heores shouting things so childish.
''Harem king and Pirate king?' Asked Mist.
''Yes, they didn't wanted the tittle that we gave them. However over time they accepted, when you have two stupid nicknames on the table you do whatever you can to make them sound cool.
''Wow! So they didn't want these tittle at first?'' Asked Mist.
'Yes, I still think they are still one thing after all these centuries.'' Said Brunhilde.
''What is it?'' Asked Mist.
''They´re both idiots.'' Said her remeberign how much hard work it was to deal with Luffy idiotic nature and Issei perversion. If it wasn't for the rest of their teams, she would have quitted from day one.
The young Valkyrie had a confused look in her face. She heard rumors that both the Immortal Pirate King and the Red Dragon Emperor weren't the smartest beings all around, but she never imagined her teacher telling that they are both idiots.
''So what about families? Do they have wives?' Asked Mist.
''The Immortal Pirate King has over 20 brides and the Red Dragon Emperor has over 15 wives. I don't want even know how many kids those two have made with their brides.'' Said Brunhilde with an annoyed look in her face.
The Young Valkyrie had a look of shock in her face, her mouth going all the way down.
''Wow! I didn't know that the Immortal Pirate King had more wives than the Red Dragon Emperor. Many talk about his brides but I never imagined it would be the opposite.'' Said Mist.
''They are good friends and the Immortal Pirate King let the Red Dragon spread rumor around he had more wives. It took some time for that Rubber idiot to finally understand a relationship works and I didn't expect him to go overboard.'' Said Brunhilde still in disbelief that Luffy made a lot of brides, but she knew of his over powered charisma and it was something she couldn't stop.
''Does the Red Dragon Emperor complain that the Immortal Pirate King has more wives?" Asked Mist.
''He complains to this day, but his wives make sure he is loved every night.'' Said Brunhilde with a hint of perversion in her voice.
The young Valkyrie blushes at that and Brunhilde let a chuckle.
''So how to they live right now?" Asked Mist.
''Well they are both super busy. The Immortal Pirate King has both adventure and meeting with his wives, while the Red Dragon Emperor is doing multiple meetings with various enterprise. Those two are busy for the next 300 years.'' Said Brunhilde.
''And what do you think they are doing right now?" Asked Mist
''Probably, who knows what these two legends are doing at the moment.'' Said Brunhilde thinking of Luffy and Issei having a great battle agaisnt an enemy god.
On the top of a mountain in one of the Nine Realms
Two young man that looked about their mid-20s where on the top of one the largest mountain in all of the nine realms. Luffy and Issei were now two of the most powerful beings that ever existed, and they were able to do things that nobody would ever imagined.
''Come on Issei, lets do this!'' Said Luffy excited while having a regular outfit that he would use when he was a regular human. Red Shirt, jeans and his trustworthy straw Hat.
''Luffy this is ridiculous, I don't know why you are still trying to do this? I am going to get a lot of damaged from these mountains. Besides I don't know why I am here; I have a meeting with your wife later.'' Said Issei while wearing a regular business suit.
''Oh come on, you and me have grown a lot stronger. Besides I want to try this out, it's going to be metal.'' Said Luffy.
''Well after centuries of hard work and training I guess we could try this. But I haven't transformed in a while, I fear that I might got a little rusty.'' Said Issei with a chuckle.
''You need to try! I know you want to do this Issei, come on!'' Said Luffy with a smile.
The brown haired man gaves a chuckle, he knows how his best friend can persuade people to do things for him.
'Fine, but you owned me a basket of Sanji dumplings. My kids plead for that nonstop.'' Said Issei.
''Deal!'' Said Luffy.
The two soon saw the edge of the mountain, they had a look of determination in their eyes, it was crazy but they were used to do these types of things.
''Ready?'' Asked Luffy.
''Yes!'' Said Issei.
The two soon run towards the edge of the Mountain and they jumped over. Soon they two started to transform into the two form that they were most well know. Issei became a giant red scale dragon that could almost rival Kaido in size, while Luffy enter his god form but this time he was like 2 kilometers of size and soon Luffy plan happen: Be on his giant size while riding on Issei in dragon form.
''Whohoooooo! I knew this was going to be awesome!'' Said Luffy with a booming voice echoing among the realm.
While Luffy was having the time of his life Issei was having a hard time.
''This amazing!' Scream Luffy.
''I can't contain all this, you are too heavy.'' Said Issei in his dragon form.
''Oh come on. You can hold a mountain to save a bunch of girls but cant hold me?" Asked Luffy.
''You weight several tons in this form, and I was trying to see some new colleges babes at the time. Wait a second why I am doing this? You can fly! Asked Issei.
''Uh I thought the red Dragon Emperor was able to sustain a lot of damage. I guess it was a lie.'' Said Luffy with a smirk.
''Urgh fine, mostly because you and me are pals for centuries!'' Said Issei.
''Alright, I am leaving you pal.'' Said Luffy getting off from Issei and getting on a regular human side near Issei, despite being a small size Luffy power was something that couldn't be luahg at.
The two soon fly around and look around the realm, having fun before going back to their duties. Despite being adults the two are still teenagers in their hearts, their wives still comment about that.
This is just something I wanted to do. Its still a long way until we reach the end of the story. My plan is to adapt the anime, have some original arcs and then I will adapt the Light Novels. This is going to be something big and I want to keep going.
I had a lot of fun making this. I won't tell the full list of wives that each one has. I already spoiled some girls in recent chapters. I want to make Luffy take responsibility, I will explore this more in future chapters, also there are One Piece women in both men harem. They are going to take a great amount of pride for their family, also its hilarious to have a ton of Will of D kids running around, which would make the World Government have a heart attack. Well see you guys later.
