Your POV
You and Issei were standing outside on the battlefield waiting to start the fight when Sirzex said something to both of you
Sirzex: If both of you are victorious in this fight, what would both of you like in return? It can be anything
Riser: What? That's mad
Sirzex: They went to all this trouble to get here, it's only fair that they receive compensation of they're victorious, so what would you like? Power, fame?
Issei: There's only one think I want, Rias Gremory
Rias: *Gasp* Issei
Sirzex: And what of you Y/N? What would you like?
You: I want answers from Riser
Riser: From Riser, what could I possibly know?
You: I want to know why you killed my parents, and who the other person was that was there with you
Rias: Oh Y/N, I had no idea Riser killed you're parents
Riser: Oh I remember you now, you're that pesky little saiyan brat who escape long ago, very well, if you win I'll tell you why
Sirsex: With that out of the way, may the fight, begin
You: Haaaaa!!!!!!
You instantly transformed into Super Saiyan Blue and got ready to fight
Riser: What?!? It can't be, that light, it's a power that rivals gods
Issei: Alright lets do this Drage
Drage: Remember, you only have ten seconds
Issei: That's all I need
Drage: Welch Dragon, Balance Breaker
Rias: A balance breaker, where did that come from
Issei: Balance Breaker Boosted Gear, Scale Mail!!
Riser: Alright lets do this
Riser rushed at Issei and quickly sent him flying into the air, he then spin kicked him into the pilar behind you
You: Issei, you alright
Issei: I'm fine
You flew at Riser and punched him in the gut and then grabbed his arms and spun him around and threw him to the ground, although he got up and rushed at you and kicked you in the stomach which sent you flying into the same wall Issei hit
You: Issei, go get him, I have a plan
Drage: 10
Issei: Alright
POV change Issei
I rushed at Riser and punched him into the air using my right hand, I then flew after him and he charged me and we punched each other in the face at the same time although I was the one who started falling
Riser: Hehe, you can't *cough blood* what the...how could you injure me, is that a cross
Drage: 9
I got up and started to walk towards Riser dangling the cross in my hand
Riser: That's impossible, a devil can't hold a cross, wait, you offered that dragon your arm didn't you?
Drage: 8
Issei: So what if I did, who cares, all I care about is getting Rias back
Drage: 7
Rias: *gasp* Issei
Drage: 6
Issei: No one is going to take anything from her that she doesn't want to give
Drage: 5
I was still walking slowly trying to buy Y/N as much time as possible, although I don't think it's going to be enough
Drage: 4
Issei: You tried to get her to marry you, when she clearly hates you
Drage: 3
Riser: You fool, you'll be ruining pure blooded devils for years
Drage: 2
Issei: Don't you understand, I din't care!!
Drage: 1
I rushed Riser with tremendous speed and was about to punch him in right in his smug face until something I didn't want to happen happened
Drage: Time
I stumbled out of the Scale Mail and Riser sent me back to where I started with a single kick
Issei: Come on Drage, give me more time, what else do you want, an eyeball, my leg, come on I'll give you anything
Drage: I'm sorry, but I can't do anymore, I've left a small amount of power in the sacred gear, but I'm not sure it'll be enough to take him down
You: Don't worry Issei, I have a plan, just boost your power and be ready to transfer it to the holy water and me, so give me the water
I handed him the holy water, the look in his eye reassured me that we were going to win
POV change You
After Issei handed you the water, you stood there staring Riser down
Riser: What can you possibly do to me boy? He had a cross and he still couldn't win, so what chance do you have?
You: More than you think, lets do it Saphira, Sacred Gear, Aura Dragon
You deployed Saphira and looked at Riser, you knew neither Koneko or anyone watching would like what you were about to do
You: Haaa!!!
A red aura formed around you blue aura and you looked at Riser and he had a look of fear on his face
You: Thanks for the time Issei, you allowed me to properly use this technique, Kaioken!!!
You rushed at Riser and in an instant, you were in his face and had punched him in the gut and then punched him repeatedly in the face and then kick him in the stomach
Riser: Gahh, how the hell did you get so strong and fast in an instant?!?
You: My sacred gear doubles my power just by deploying it, and the Kaioken doubles my power and speed on top of that, speaking of which, Haaaaa!!!
Riser: What?!? He's multiplying his power even more?!? By how much times 4, times 5, no...
You: Times ten!!!!!! Saphira deploy the dragon blade
Saphira: Right
The blue energy blade enveloped your hand as you stood their looking at Riser, you charged at him and kicked him in the stomach and then uppercutted him which sent him flying into the air, you flew after him and were soon behind him and you then used both you hands to smash his head which sent him flying into the ground
Saphira: Y/N, this form won't last much longer, you need to end this now
You: I guess it's time, Issei do it now
Issei: You got it
You flew down to where Riser was and it looked like he was unconscious, but he then grabbed you and pulled you up by the collar of your shirt, you could barely move your muscles due to the Kaiokens effect on your body
Riser: Now I'm going to kill you, just like I did your father, but since you wanted to know so badly I'll tell you before you die, the devils and the church knew of your family's Saiyan powers, they thought you could benefit one of the sides, but your father didn't want to join either side, so the church and devils both hired one person to hunt down and kill your parents, I don't know who the other person is, but someone from the church might
You: What?!? But who hired you?
Riser: I was hired by non other than the devil king himself Sirzex
Rias and You: What?!?
Rias: Brother, is this true?
Sirzex: *sigh* Sadly it is, although I was not aware at the time that Y/N was the son of those two
Issei: Y/N I'm here, let's do it
You: Right
You pulled out the holy water and opened it and Issei transferred his power to you and the water, you then threw it in Risers face
Riser: Ahhhhh!!!
Akeno: Not even Riser can regenerate when his mind is under this kind of attack
You: Time to end this...once and for all
You kicked Riser into the sky and teleported behind him using instant transmission and did a backflip and kicked him back into the ground, you flew down to him and he was still in pain from the water, unable to heal, you pulled out the cross and rushed up to Riser and grabbed his shoulder and lifted him to where his eyes met yours
Riser: Your both idiots for ruining pure blooded devils
You: Silence fool
You punched him as hard as you could with the cross in you hand and he fell to his knees unconscious and unable to fight any more, that's when his sister flew in to stop you from ending Riser which you were about to do with the Dragon Blade
Ravel: Stop!! Please don't hurt him
You: Unless you want to be next, you'd better move aside girl
Ravel: *gasp*
Rias: You both did it, you did it, Issei, Y/N, I owe you both
Your transformation ended because your body could no longer handle the pressure it was taking, suddenly the floor disappeared and you could barely move, you were in no condition to fly, that's when noticed you were no longer falling, you looked to see who caught you and it was none other than Koneko
You: Hey...Koneko, when did you...get here
Koneko: I've been here the whole time, I'm so proud of you, you did it, you beat Riser
She started to hug you and you would have returned the hug except for the fact that you were unable to hug you at all due to the stress and pressure your body had taken during the fight
You: I...I think I'm...going to rest for awhile
Koneko: That's a good idea you do that big guy, I love you
You: I love you to Koneko
You felt her give you a kiss on the lips which you gladly returned and after 10 seconds she broke the kiss and you felt your self pass you, however before you did, your thoughts were that only half of your mission was complete, you still needed to find out who the killer from the church was, the only was to that was to find someone from the church who would be willing to talk
