Soon Rias Got Dressed and quickly called up A Family Friend as you were both standing in her personal room in the ORC Waiting for her to arrive.

Just then A Blue Summoning circle appeared and suddenly A Maid appeared from the floor in A Flash of Blue Light.

Grayfia: I'm Glad you finally picked out A Man you would like to be married to Rias-Sama. He is Cute~

Y/n: (Blushing) W-Well thank you...

Rias: Grayfia can you take us to the coliseum?

Grayfia: Of course Rias-Sama.

Y/n: Excuse me what?

Grayfia then teleported you all to the Coliseum in the realm of devils as of course Rias's Older brother and the Current King was residing waiting for you two to arrive.

Sirzechs: Rias, I see you finally Picked the man who will be fighting for your hand, so Nice.

Rias: That's right, He's the Man I truly love, Not Riser, So He will fight for my Hand.

Sirzechs: Good, Good. He should be here-

Riser: Riser is here Now, And... (Glares) L/n.

Y/n: Chicken.

Riser: IT'S RISER AND YOU KNOW IT! I-

BAM!!!

His entire head then Blew off into Bloody Bits.

Sirzechs: How do you remember he's Immortal after all this time?

Y/n: Huh? Damn, I forgot.

Riser then got up his head in flames as he then revealed his entire head Grew Back.

Riser: WHY YOU LITTLE! RISE WILL NOT-

Sirzechs: RISER STAY DOWN!

Riser then Backed down knowing how strong Sirzechs Is.

Sirzechs: May the Battle Begin Now!

Suddenly you and Riser were teleported down to the Arena floor as You Looked at Riser with A Slightly angered Look.

Y/n: Look Riser, You Lost to Issei once before and It's A Well known Fact that I am Far stronger than he is so Just stay down.

Riser: You Can shut your Mouth Now! Riser will eliminate you! Take this!!

He then shot out A Flurry of Fire attacks towards you which Lit up the entire area and he then Jumped back!

Riser: HA! How do you like Riser's- GAH!

One of his Knees was Blown out by A precise blast and then his other knee and then both of his Elbows.

Riser: AAAAAAAAAAAAGH!!

Y/n: You Know, That was pretty Pathetic even for you.

Riser: You Know what Happens to A Phoenix when they die right?

Y/n: Let me guess they are reborn through-

Riser: THEIR ASHES!!

Riser was then surrounded by Fire as he had A Giant Susanoo of the Legendary Pheonix!

Riser: DO YOU LIKE RISER'S PHEONIX!? IT IS ALL POWERFUL! YOU CAN NEVER KILL IT!

Y/n:

Sirzechs: Wait, what is he doing?

Rias: (Smirks) Give it A Minute.

Y/n: Y/n Kick.

Riser: Wha-? GAAAAAAAAAAAAAAAAAAAH!!!

Riser then slammed into A Wall as his healing kept Kicking in to heal Any Damage but you Just slowly Began walking over and then Grabbed him by the neck of his shirt.

Riser: GAH! (Spews up Blood) Riser will Rise again... Riser will-

Y/n: Stop your third person Bullshit. It doesn't work for your dumbass.

You then Punched crushed his Jaw and then punched his chest ripping it out as you Placed it in his now Jawless Mouth.

Y/n: I want you to eat it. Every Last, Bite.

You then began squeezing his school until it blew up into A Shower of Blood, Guts, and Skull Bits.

Riser then Began slowly healing as you Turned to them.

Y/n: Hey we're done here? I didn't even power up and I still Kicked his ass around. I figured he didn't Train... Like at all.

Grayfia: O-Oh My!

Sirzechs:

Rias: Yep, that's my Future Husband for you~ Now you won't have to worry about our "Precious Bloodline" ever again~

You Just began walking off looking for something to eat.
