Hello there reader. I've been reading fanfiction for a while and decided to give this little thing a spin and see how it goes. I hope you enjoy.

I don't own Dragon Ball Z or Highschool DxD. They are owned by their owners and companies. Support the official releases. Before anyone asks, No Tien is not going to be in Rias's peerage. Tien would never let that happen. Even if somehow he died, Rias doesn't have even a fraction of the power to turn him.

"WHAT ARE YOU DOING?" - SHOUTING

"What am I doing?" - Thinking

"Why did I do that?" - Speaking

What drives a man to become a warrior? For some it's the need to prove them self. For others it's to gain power over themselves and the world around them. For others, it's tradition and heritage. For Tien it was to survive. Times of peace are fleeting and never last long for the weak. So the story goes for Tien, the sole survivor of the Three Eyed People.

What drives a man to be a Hero? Pride? Honor? Fame? A good heart? A will to protect those who could not protect themselves? A hero is many things and many more. A Hero forges the way forward for oneself and others. A hero is a light to fight away the darkness.

-Introduction-

The fight with the monster Majin Buu was over. The universe ending danger had passed by much to the relief of quite a few of the defenders of the earth.

One of those brave defenders by the name of Tenshinhan or as his friends and acquaintances called him, Tien.

He was meditating in a quiet room of his Dojo. The room was rather empty. If not for the red and black cloth mats on the floor, the weapon racks filled with quarterstaffs, poleaxes, blades, and the larger mat he was hovering slightly above in the air, it would be an empty wooden room.

There were two thin rectangular windows at the back wall near the ceiling, letting in some much-needed mid-day summer light.

Tien sat in the air with his legs crossed in front. His hands hung by his sides, his arms slightly bent to align with his legs.

His large muscular chest was bare and exposed showing his massive rippling pecs and abdomen.

His lower body was garbed in dark green cotton pants that were quite loose and gave quite a lot of room.

His boots were dark black with a white cloth wrapping at his heels.

His third eye was glowing slightly as his psychic energies were constantly aligning, growing, and realigning to compensate for the increase in energy.

He stayed in that position for four more minutes before righting himself midair and touching down.

Opening his eyes, Tien let out a deep breath. It was a successful training session.

Not only did he take a strong focus on physically improving, but he also took a sincere focus on maximizing his psychic potential.

Walking across the room, the psychic practitioner opened the dark green curtains that served as the door to the meditation room by pushing them aside with a slight 'thhwp' noise as they slid across the metal pole that held them and hit the walls.

Today was the day he took time off from teaching his students and focused on his own physical and mental improvement. He took one day a week to do so every week with almost no exceptions.

The room he entered was his personal quarters. The room was not very large, barely more than a two-room square apartment.

It had the necessities, being a bed, clothing dressers, a table next to the bed with two chairs, and a bathroom.

The bed was across from the meditation room in the middle of the wall. The table was to the right of it and the dressers to the left.

The floor was wooden with a simple and soft wine red rug.

On the table were two picture frames, one with a picture of a younger Tien looking slightly flustered as Launch in her blonde form was on his back over his shoulder with a large grin as she pulled his ears.

The other was a picture of him as a small child, his mother, and father standing over him with smiles, each with a hand on his shoulder. It was the only thing that tied him to his past in the Three-Eyed Clan. Walking over to the table and picking up the picture of his family, a small tear formed under his left eye.

Even though he had lost many of his abilities due to his time working under Master Shen, he had not lost all. He still in spirit was connected with his ancestors. Looking at it for a few moments, Tien closed his eyes savoring the memories of his past while he still remembered them.

However, he was broken out of his reverie when one of his students came running to his room before stopping at the door and bowing to him.

"Master Tenshinhan! A green portal opened up in the middle of the stairs to your building.

What do we do?" The student asked Tien with wide excited eyes.

Tien placed the picture frame back on his table and looked seriously at his student.

"I will investigate this, make sure nobody goes near. If anything happens to me, go to Bulma Briefs. We're not the best of friends, but I'm sure she would help with an incentive" Tien said before striding by his disciple and leaving the building.

The land where the dojo Tien owned was quite sizable. Not only was it a place for fighting, but he also owned the villa below the dojo that was settled at the top of a small mountain. There was a long line of steps from the foot of the mountain to the Dojo.

When Tien arrived halfway down the massive stairs, he looked at the portal swirling there. A group of students stood around it, making sure nothing came out.

"When did this open up?" Tien asked a nearby student who bowed to him and explained the situation. Walking close to it, Tien stretched his psychic energy, and Ki sense to it, preparing for any backlash. Nothing happened.

It was like a small tunnel. Stretching his Ki sensing through it, he could sense some living creatures close to the portal.

He then stepped in front of the portal. "Bring me a poleaxe," Tien said to a nearby student as he reached out a hand. A student ran off to get him a poleaxe. A minute later the student returned with a six-foot-long poleaxe with a large steel head. Handing it to his master, the student stepped back.

Tien slashed lightly at the portal, ready for any form of physical reaction. It passed inside harmlessly. No explosion or retaliation occurred. Placing the poleaxe on the ground nearby, Tien flared his Ki.

"I will go inside of it. Stay back" Tien said before walking slowly into the swirling ten-foot circle of energy. When he passed through, the portal closed behind him leaving the students on an empty staircase without their master.

"What do we do?" was the thought that went through all of the student's heads.

-Chapter One-

When Tien stepped through the portal, he was greeted by an explosion that blasted him from behind, pushing him forwards a few meters before he righted himself mid-air. His Ki had protected him from the shrapnel of the exploding machine that had blown up upon him going through the portal. Having gathered himself, he looked around to figure out just where he was.

Around him were concrete walls and various control panels that blinked and hummed with various lights and beeps. Behind him was a mangled metal mass of what used to be a portal shell. The ceiling of the room was a flat rough concrete with long fluorescent lights that were protected by metal and hard glass.

Around him on the floor were the bodies of four humans in lab coats that were shredded and covered in blood from the shrapnel. All of them were dead. One was a tan woman in her mid-thirties, her frizzy dark hair disheveled and coated in blood. The other three looked to be a mix of young men in similar lab outfits equally disheveled. All of them looked malnourished and were covered in signs of abuse.

Floating down to the floor, Tien checked their Ki. They were all dead. Seconds later, he heard the sounds of heavily booted feet rushing towards him. Most likely security if the feeling of the lab was to be trusted. The humans looked disheveled and damaged even before their deaths. Tien had dealt with similar things before under his master Shen. Men, Women, boys, and girls would be kidnapped from all over the world and sold to all sorts of degenerates and labs for good Zeni. He had stolen things from labs before and had seen the product of human trafficking.

Those four that died were most likely kidnapped and sold to work as lab slaves wherever this was. Tien wasn't excessively concerned as Gohan or even Goku might have been, but it did give him a feeling of disgust. Even though he had changed his ways to an extent, he still realized that some of the strong would always take advantage of the weak.

The only entrance to the room was a set of concrete stairs going up to a steel slab like blast door that didn't seem to be opened from the inside. It seemed a confrontation would be unavoidable if he didn't smash through the ceiling right now. The people coming had warped Ki. It was violent and sharp. Like the head of a halberd.

A rumbling was heard as the door slid upward into the ceiling slowly. The sound of someone speaking came through roughly.

"Those human shitstains messed up again. This is the tenth time" Came the sound of an angry woman, her high pitched voice sounding very angry.

"They're humans, did you really expect any better?" Came the agreeing voice of a middle-aged man closer than the woman.

Seconds later, five humans with black bat-like wings that spread out from their backs a good four feet on each side walked into the room. They held maces in their hands that glowed a sickly green. The woman was a light tan with short slicked white hair and looked to be in her mid-twenties, wearing a gray business suit with a badge emblazoned onto her left breast that was a large white M.

The men wore a similar suit with the same m, all with a light tan. Their hair was white and their eyes all were red with black sclera.

Taking a look around, The woman who was clearly the leader of the group looked Tien up and down before pointing her mace at him lazily. Aside from his weird eye, he was clearly a human. There was no evil, angel, or fallen energy coming from him. He wasn't a direct threat, but she wouldn't underestimate him just yet.

"Hey three eyes, did you do this?" She yelled to him while pointing her mace to the humans dead on the ground full of shrapnel and burns.

Tien looked back at her unintimidated. Her weird Ki was of no threat, barely equal to some of the martial artists in the twenty-second Budokai. The men next to her were also relative to her.

"If I said I did? What would you do?" Tien responded, stretching a little in preparation for what he might do. Not intimidated in the slightest.

"It looks like the translation magic put into the portal works. As for humans, they were cheap trash. I don't care about them in the least, but you destroyed the portal our master Malthus spent so much time and money on. We can't have that. If you cooperate, we'll make you a slave. If not, you're just another dead body" She said before exploding towards him with the other men at her sides, maces ready for striking.

"It looks like I'm going to have to kill you," Tien said, flaring his Ki. He wasn't a champion of good and didn't really care too much about the dead humans around him, but he wouldn't allow himself to be enslaved. If he knocked these people out or flew away, they might go to their master and cause him trouble later. If he wanted to escape quietly, he would have to kill them.

Faster than any of the devils could comprehend, their necks were instantly snapped midair. The thuds and clanks of bodies and maces dropping to the floor in front of Tien resounded across the room.

Tien lowered his right hand he had extended to utilize his psychic powers. He had snapped their necks with his delicate telekinesis. None of the outfits would fit him and he wasn't proficient with a mace so he let the bodies lie on the ground and walked up the stairs. Entering a hallway that was in stark contrast to the room he had just entered, Tien looked around.

He was in a long thirty-meter hallway in what seemed to be a basement. The walls were polished redwood and the floors were carpeted with opulent red a gold-threaded rugs. On the walls were portraits of men and women that looked similar to the ones he had killed. This seemed to be a very large family.

At the far left end was a staircase going upwards and the right end was a wall. Going toward the stairs, Tien sent out his Ki while feeling for more life. It seemed there were five floors above him all with more weird Ki. Those winged people had a strange Ki, similar yet different to humans. He had two choices, Fight his way through or speed through the house so fast he couldn't be seen.

He took the latter. Faster than the devils could begin to comprehend, Tien sped through the house and out of an open window into the blue sky. At least he thought the sky would be blue. Instead, it was a swirling mass of red and gray energies that twisted and turned. Now sufficiently high, easily miles above the ground, Tien came across floating islands of dark obsidian. On them were some kind of red and white gemstones that were pulsing with energy that flashed out into the sky. When Tien approached one of the islands, he came to a forty-foot wide square platform with glowing crystals.

The gemstones were as tall as him in close clusters. Reaching his hand out to one, he hit a force field. It wasn't very strong and he could break it, but he didn't want to draw attention to himself so he retracted his hand and flew higher. The islands continued for the next two miles before they fell under him eventually becoming specks in the distance. Flying further and further, he eventually came to a massive area.

It was a large obsidian platform that spread for half a mile in every direction.

There were old decrepit benches made of rotting wood forming two lines near the middle. Empty granite white oval portal shells stood like gaping maws on each side of him as he walked. Near the far end, he heard a light and faint humming from one of the shells. It was unnerving in the silence he had gotten used to. This area had clearly been long forgotten if the state of the place was to be taken at face value.

Speeding up, Tien flew towards the portal and quickly arrived. It was eight feet tall and a box shape. A thin translucent film of white energy flickered weakly in the box. At the right side was a granite plaque that had "Ja**n Earth" Carved into it. He didn't know what the JA**n meant but he did recognize Earth. Staying wherever he was was most likely a bad idea and if this portal took him to Earth, things would be better.

Stepping through to portal, Tien was hit in the face with branches. When he stepped out, he arrived in the middle of a small forest.

Turning back, the portal was nowhere to be found. Pushing the low branches to the side, Tien saw the blue summer morning sky above.

Sensing with his Ki, he sensed many many humans. Far more than he recognized on Earth before. However, he couldn't sense anyone he knew. Nobody.

"This seems like trouble," Tien said before flying into the sky.

And cut.

Thanks for reading the teaser. Let me know what you think.

I know some people are going to say Tien won't kill, but I disagree. He's not Gohan or Goku, he has no problem killing. That's not to say he's some edgey Lucy or Ken Kaneki serial killer, but he has no problem killing people if they try to kill/enslave/maim him etc.
