I've been reading The rising of the Shield Hero and wanted to write a crossover with it. So far I've only read the manga up to book hero.

Who better to use than Mirai Trunks?

It's not just because hes edgy, its because his attitude and mindset fit in this verse the best out of most Dragon Ball Z characters.

In the beginning, Trunks is op but once it gets to the gods in shield hero that are at the very least universal with a plethora of hax he becomes weak. In that tier hes fodder unless we count the rage power up he got against Zamasu.

That's where the sword comes in. Naofumi went from average human to universal with the help of his shield and other factors. Trunks can do it too, if he trains hard enough and fulfills the right conditions, his weapon can allow him to reach those heights.

As for the other Dragon Ball main characters, here are my thoughts.

Goku definitely would not be a good fit for this as while he is strong, he's easily manipulated, Isn't good at mind games and would probably end up fucking everything up for his sense of Justice and looking for a fight.

Vegeta, while he would make for an amusing story, would not do anything to help anyone and if he didn't find a way to leave the planet, would probably end up poisoned or killed in his sleep by one of the innumerable enemies he'd make. The funny thing is Vegeta probably wouldn't believe Naofumi raped the princess just by looking at him.

One, Vegeta has probably raped a few women in his younger days and even if he hasn't, he certainly has known a few Saiyans who have and has met countless people so he should be a good enough judge of character.

Two, he would see Naofumi as too weak and pathetic to do it in the beginning.

Three, the most important thing is he wouldn't give a single fuck even if Naofumi did.

It's not his universe and he has no ties to anyone there.

Gohan is similar to Goku with justice and would probably end up doing more damage than good with good intentions but unaware of the consequences of his actions.

Krillin would fall into the same traps as Goku or Gohan to a greater extent.

Piccolo would be semi interesting if I wanted morally preach to you.

That aside, I don't really have much to work with if I put him there. From what I understand, he would probably research for a while before going off to train and only appear for the waves. The other Heroes would be intimidated by him from square one and probably wouldn't talk with him much as he would probably be evicted from Melromarc as soon as he arrived. He would probably not even fight it and just 's not really much anyone in the castle could do to him.

The waves would be of no problem to him as he'd just spam Ki blasts and that would be it. No tension or anything. The other Heroes wouldn't be able to hurt him at all besides Naofumi after becoming a god Slayer.

Tien would definitely be very interesting to see in the shield hero verse but honestly, I don't know enough about him to properly judge his character correctly. Honestly that sucks because I like Tien a lot.

As for Seventeen and Eighteen, I don't want to do my boy Krillin dirty by taking away his wife, and removing seventeen or eighteen would mess up team seven.

One last thing before I get to the story, Ren is a decent character in his own right but really dropped the ball later on. Trunks will be replacing him in this story. He's the character that would be the least damaging to remove, besides, trunks is really the only guy in Dragon Ball Z that consistently uses a sword.

I mean Gohan had the Z sword, and there was always Tapion but lets be real, not many people care about Tapion including me.

Now that you know what you're in for, let's go!

EDIT 12/30/2019

So, I decided I wanted to get a new take on this involving Trunks's Saiyan roots so I rewrote the first chapter to fit with my idea.

It might add a little more spice to the story so to say. I think you know where I'm going with this.

Intro

The four heroes arrive

Ruins of Green Oaks Village

Trunks

It was summertime on earth and Trunks could finally enjoy the warmth it brought without feeling a city or town being destroyed by the monsters called Android Seventeen and Android Eighteen. Flying through the sky, he felt the wind ruffle his hair and black T-shirt wildly as he smiled.

His muscular arms had quite a few scars and bruises that never fully healed like most of his body from all the fights in his life. The Androids would hurt him just enough to cause a lot of pain and damage but never anything fatal.

He had spent years in fear and anger, only smiling when his master Gohan was with him or when his mother spoke of the good times long past. It felt so good to smile genuinely, to smile a smile without the worry and pain that usually came behind it. Sure, there were petty criminals that tried to rob and kill people after the androids disappeared, but they were swiftly dealt with by a mystery man that glowed gold.

Being able to sense Ki allowed one to sense the emotional state and vaguely sense the intentions of the sensed beings. Another ability Trunks had used and honed was his heightened senses like hearing, smell and sight that came from being half Saiyan. His mentor Gohan had told him stories about his Father Goku being able to smell food from almost a mile away, smell and see a small stone from across a forest alongside many interesting tales.

"Gohan... I hope things are going well for you in the afterlife" Trunks thought as he did loops and swerves in the air. After he had ended the Android menace and destroyed the monster that was Cell before he could evolve, he had took it on himself to help the world rebuild from the damage he felt he was partly responsible for.

That's why for the past month, he had been flying around and helping towns and cities he passed. As he dropped down from the sky to the investigate the burnt and charred houses that made up most of the tiny town of Green Oaks, he sensed for life with his Ki. There was nothing that showed up at first, but right as he was about to fly away to another town, he felt a strange energy coming from a larger domed building than most in the small town. He began walking over to the building to check it out and as he got closer he saw a hanging wooden sign in front of the building that said Library in bright orange paint.

When Trunks pushed one of the doors open, it fell off of its semi destroyed hinges with a loud thud, making Trunks almost jump. After looking around to make sure no one saw him push it down even though he knew no one was there to see it, he stepped in to the Library. The roof was gone and a few birds had flown out of the library from the thud and Trunks entering so it was bright inside. Walking to the source of the energy, he found a book titled The Legend of The Four Heroes lying closed on the ground.

The energy the book emitted was not harmful or dark in any sense but it was strange.

"Why not give it a little read? I've flown around all morning. I'll take a much needed rest and read for a while".

Thinking it would be fine to read for a while, he set down his sword against the bookshelf he had sat down against and started reading.

"In a world beseiged by war and conflict, tragedy struck. The world became dyed in a purple hue as portals to twisted dimensions opened in the sky, flooding the world with monsters. The nations and churches fought back for a long time but eventually began to falter. When all hope began to turn to dust and sand, the nations cast rituals to summon the four cardinal heroes to fight back the hordes that violated the land.

The brave heroes summoned were the Bow hero, the Sword hero, the Spear hero and the Shield hero.

As Trunks read the book he became invested in the story so much, he lost track of the world around him.

By the time he lifted his head from the book, he was exhausted.

"Maybe I should just take a little nap. There are no more horrible enemies to fight and no world ending threats to fix. I've earned this"

Trunks smiled as he nodded off to sleep. Then the ground beneath him shone yellow as he began to disappear. Moments later, he was removed from universe seven.

Melromarc palace

Trunks

Hearing the sound of people talking very quickly to each other, Trunks opened his eyes.

He was laying face up on the floor of a huge stone room that was lavishly decorated with tapestries, Stained glass windows and ornaments like coats of arms and opulent carpets.

Trunks was noticeably and rightly confused. Did he fly somewhere else in his sleep? Was he Kidnapped?

He dismissed that idea since he wasn't bound, not that he could be bound by rope or handcuffs if he didn't want it. Rolling over and getting to his feet, he saw the room in full. He had very little time to read books and certainly never played or heard of anything like a fantasy Mmo or Rpg, so the scenery was completely new to him. The internet was long destroyed by the time he was four so knowledge of anything other than fighting and the machines his mother made was incredibly scarce.

Free time to do something he wanted to do came by very rarely and it was spent sleeping or fishing with Gohan. Either he was training with Gohan, training by himself or helping his mom with the Time machine. As he thought about the past, his brown furry tail swished back and forth out of the top of his black martial arts pants.

"Wait. My tail grew back? Crap! Not good" Trunks panicked as he turned his head down to look at the swishing tail he owned. Something that surprised him more than his tail growing out was a three foot sword in a silver trimmed black scabbard that seemed to be attached to the right side of his pants through unknown methods.

Then he looked around at the people in the room for the first time. At the double doors behind him there were four men in metal plated armor holding spears while looking at him warily and aggressively. To his left he saw three other young men looking equally confused.

The first one was kneeling on the ground, a small light colored metal shield attached to his right arm over a green hooded shirt that covered his head, arms and upper body. The young man had clean black shaggy hair and light skin, He looked to be taking this better than Trunks, as if he somewhat understood the situation.

The next young man seemed the youngest of the three and had a messy short blonde head of hair, wore a green dress suit and had a bow and capped quiver on his back. He had a smile on his face like he knew full well what was going on. The final young man was a tall, fair skinned, blonde long haired young man who had on a black dress jacket that was opened in the front, revealing a red silk tie and a pressed white button down dress shirt.

His black slacks and expensive black dress shoes were spotless and pressed, showing his attention and diligence. Rising at a one hundred degree angle from his back was a long metal spear. He also had a smile on his face alongside a glint of recognition in his eyes.

Lining the walls were more men in plated metal armor, though these wore swords and kite shields. Their Ki was slightly higher than the ones at the front doors.

above him to the right about fifteen or so feet away was a large balcony that was filled with men and women in brightly colored clothes Trunks had never seen in his life. Come to think of it, everyone in the room besides him and the three young men wore clothes he had never seen before.

Then something popped up in his Ki sensing. He hadn't noticed it at first since he wasn't searching hard but there were faint Ki signatures that belonged to female humans in empty spots of the room.

"Invisibility? There is more than one here" Trunks thought as he looked directly at the places the Ki signatures were located.

He felt their Ki waver slightly as if they were surprised he saw them but they made no move and showed no sign of hostility so he didn't say anything. Speaking of hostility, quite a few men and women on the balcony and some nearby him radiated it towards him.

He didn't know why, but he didn't let it get to him. Expanding his hearing, he heard quite a few things.

"Is it really a good idea to summon all four heroes?" one man whispered to a woman next to him.

"To think the sword hero was a demi human. Be careful around him, the demi humans have no respect for humans" A woman said to her other female friends.

"A demi sword hero and the shield hero? What were the king and princess thinking?"said one man wearing a silver necklace that had a small depiction of a sword, bow and spear hanging on it.

"Filthy demi" he yelled at trunks before he took the necklace off and threw it at Trunks who by instinct rather than recognition, shot his hand out faster than anyone in the room could see and caught it. To the few who payed attention to him, all they saw was a necklace appear in his hand.

Looking at the thing he had instinctively caught, Trunks let out a confused "Huh?".Trunks had no way of knowing what the symbol on the necklace was, so he really had no idea how to respond.

"Silence!" A loud and commanding voice reverberated through the room, causing everyone to instantly quiet.

Down the red rug at the head of the room was a platform with stars going up it.

At the top of the platform about five feet above everything else was a large set of two thrones side by side, on the one to the left was a man in what looked to be in his late fifties. He had long gray hair and a short, well maintained beard.

His slightly wrinkled light skin stood in contrast to his dark eyes that showed a mixture of regret and relief. He was leaning his right elbow on the right arm of the throne with his hand on his chin. His white shirt had thick gold lining and gold etchings on the purple robe that he wore on top of it.

His crown was about six or seven inches high and made of solid gold and had a large purple gem in the middle.

All in all, he looked like a tired King.

Around him were quite a few men and women in the same colorful attire as the ones in the balcony, but they all had quite high Ki in comparison to the rest of the must have been quite important people.

The other three young men looked at the source of whoever the insult was yelled. They each had different reactions.

The young man with the Shield looked at the young man that looked straight out of a shounen manga.

The young man was incredibly muscular, like all he did was work out. However, his scars told another story. He must have been either a gang member, criminal or underground fighter.

His eyes were dark and serious and his mouth looked like it was in a permanent scowl. Naofumi honestly felt a little intimidated at the aura the guy let off unconsciously. Wherever he was from, it wasn't easy like his life had mostly been in Japan.

The tall blonde man with the spear was shooting him interested glances like he was intrigued by the young man.

Other than that, he didn't outwardly show much.

The younger guy with the bow was shooting awkward glances at him while slightly inching away.

After silencing the crowd, the king stood up and walked to the edge of the platform and greeted the heroes.

"Welcome heroes, to Melromarc. I am King Aultcray the thirty second and require your help in saving the world"

"Eh?" came the collective question from all four heroes.

And cut.

That's it for now.

See you in the second chapter.
