(He's a male Saiyan that's 17 years old. This is the story where he meets everyone from the ORC Kuoh Academy and Goki from Dbz. So let's begin shall we.)

(Author Pov)

It's been seven long years since the last saiyan warrior home world was destroyed by an unknown event. He was 10 years old at that time when it happened. So he was training ever since then. However things were going to get quite interesting for him when he sensed an unknown energy signal that was heading straight towards him. He got into his fighting stance and to prepare to fight it head on.

--------meanwhile in another universe----

(Goki pov)

Thanks to everyones efferts, I finally gather enough enegry and I was ready to finish off Kid Buu with the Super Spirit Bomb.

Goki:"Alright Majin Buu this is where it ends for you."As she throw the spirit bomb towards at him.

He was laughing at her as he was charging up his kamehameha to stop her super spirit bomb from hitting him square on.

--------in the Orc room-----

(Rias pov)

I was talking to Akeno while issei was just being his pervert self while Koneko was sitting down and eating.

Rias:"Alright everyone today we're going to deal with a stray fallen angel."

Issei:"Geez how many are there Rias?"as he looked at her directly.

Koneko:"stop being a baby you perv" while she was still eating her snack shape like a fish.

Asia:"its alright Issei"she said to him with a gentle and warm smile on her face.

Kiba:"At least try and help this time Issei." As he said that while leaning up against a wall.

Akeno:"Rias may I take Issei for a quick minute?" As she was looking stright at him.

Rias:"ok Akeno but no funny business alright"she said so that Akeno would listen to her.

Akeno:" Ok Rias, and I promise that there won't be any funny business ok."

(Akeno pov)

She was walking towards Issei and grab him by his hand and they both left through the doors when Xenovia was about to walk in the room.

Xenovia:"oh hey Akeno and Issei. Where are you too going right now?" She asked Akeno and Issei wondering where the both of them are going to at this time. (It was 8:45 pm at night. So please bear with me on this one alright everyone🙏)

Issei:"Akeno is just going to talk to me for a minute and then we'll head back in the room alright Xenovia." He told that to her so that he can be sure if she heard it coming from him.

Xenovia:"Ok Issei I believe you." As she looked at him and then at Akeno who was just nodding her head at her then she walked pass both of them and entire the room for the meeting was still going on

-----back to the saiyan warrior----

(note I'm going to have his hair blue wither then yellow and no its not Ssj blue its his first transformation. But I'm going to make his Super Saiyan god form with purple hair then Ssj blue alright)

(His Pov)

I was standing alone in a plains area, but I admittedly sensed an energy signal that was closing on me fast, so I turned around to see who or what this energy belong to and were it was coming from so i can be prepare myself to fight it and in a matter of seconds this unknown alien who came out of no where was right in front of me, so I said this to my attacker loud and clear.

???:"Who ever you are you picked a bad day to fight me!" As he went straight into his Super Saiyan form and looked at this unknown Alien who was throwing energy spheres at him.

(Attacker pov)

As I was throwing ki blast at this saiyan who hair color went from black to blue in a instant. So I kept on firing waves and waves of ki blast at him while smoke begin to form from the ground all around him. But to my surprise he wasn't even injured at all and he was smirking at me,so I shouted at him.

???:"What the hell are you?!" He asked the Saiyan that teleport in front of him looking straight into his eyes with an angry expression on his face while I was shaking in fear from his power alone.

???:" W-what's are you monster!?

???:"Me a monster no I'm just the last of my kind that is a very powerful race,so say goodbye"as he punch his attacker in the face that send him flying backwards and he grab him by the leg so that he can spin him around and toss him up in the air and he begins to charge up his attack straight towards him who stop in mid flight and saw that he was charging up his attack to end him for interrupting his meditation.

(Unknown attacker pov)

As I stopped mid flight I looked down and saw that he was charging up his energy beam at me so I began to do the same as well.

???: "let's see if you can stop my attack filthy Saiyan"as he throw it at the saiyan but to be stop by his own energy blast

???:"you never standed a chance against me"as he put only a quarter of his full power into his blast and beginning to push back the attack towards its own user.

--------a beam struggle was happening with Goki and Kid Buu------

Goki's Spirite bomb was pushing his kamehameha back at him but with Buu letting the sprite bomb hit him he didn't know that a wormhole was behind Goki so, he smiled evilly and said to her." Majin Buu may be gone but you no return back home" and just like that the attack took him out with all of his cells.

Goki finally put to an end of buu horror and Vegeta was looking up at her and gave her a thumbs up to her but he didn't notice that a wormhole was pulling her in and disappear from sight with her and with a brown bag full of senzu beans as well all but one was left for Vegeta to eat so that he can regain his strength to stand up.

(Vegeta Pov)

As I watch as Kaka was being pulled in by a warmhole, I was speechless at what just happen.

Vegeta's mind:"What just happin to Kaka?" He said to himself and wonder if he should tell chichi that Goki was pulled in a ramdom wormhole and vanished without a trace. Then he turned around to see supreme kia was looking at him ready to take him back to earth.

(Supreme kia pov)

As I walked towards Vegeta I said this to him.

Supreme kia:"Well Vegeta thanks to you and Goki the universe is safe from majin buu" but at that moment he notice that Goki was nowhere to be found.

-------back to the last saiyan warrior----

(His pov)

As I walked over to see this person was and he was on the ground inside a crater while breathing heavily as he looked up at me and said with his final words before he pass away.

???:"Heh you may have won the battle but not the war my friend." As he shot me in my head and at that moment another personality emerged from with in my suspicious.

(His pov)

As I took a couple steps backwards I begin to shake my head and walk back at him and I barked at him.

???:"Agh!! What the hell did you do to me!?"I shouted at him and grab his armor shirt to pick him up so that I can look at him.

He was laughing at me and he said his name to me before he was gone.

Olina:"My name is Olina and what I did to you was put a completely different personality in your suspicious. So have fun controling it." And just like that he slowly begin to close his eyes on me.

(The warrior pov)

As I thrown him back into the crater, I leap up into the air and fire an energy ball straight towards him that ended up taking him out but I didn't notice that a weird wormhole was right behind me that pulled me into it and that's when I blackout from being pull from where I was at.

(Both him and Goki was put in the universe of high school dxd but in different locations from one and another.)

(His pov)

As I slowly woke up and to my surprise I was in the middle of a forest,not knowing why I was here but I could tell that a strange energy was coming from a different area so I got up and take to the sky to power up a little to figure out if this energy can feel my presence.

???:"Well here goes nothing. Haaaaaaaa!" And at that moment from the area that I felt and Kuoh Academy, all of them can feel my incredible power even hell and heaven felt it as well.

(Pov change to Goki)

As she was still tired,she senced this incredible power that was coming from the north.

Goki:"What was that energy I just felt?" As she took a senzu bean from the bag and put it in her mouth so she can be at full strength. Once she was at full strength,she then fly towards it to see if it an ally or foe.

Goki:"I need to check this out before it fades away completely." And just like that she flow towards it at olny half of her normal speed.
