SMG4 × Highschool DXD: Memes Vs Devils

Prologue: Going To Another Universe and Training

(Author: Guess what? The fat, dumbass plumber ain't going in alone. You, the reader, will be going in with him. Cause someone has to keep him under control right?)

Y/N POV:

I was just lying down on the sofa playing "Pokémon: Platinum Red" on the GBA emulator on my phone since the original one kind of messed me over. In what way, you ask? Well, the frame rate is slow, and the audio is kind of messed up as well and doesn't have the game cover that the other games I downloaded have. Maybe because it's a DS game and not a Gameboy game. Anyway, I felt weight next to me, so I leaned my head to see my friend Tari playing her games as usual. Then she and I heard an explosion outside.

Y/N: The heck was that?

Tari: I don't know.

Y/N: I'm going to check it out. [Gets up from the sofa]

Tari: Be careful.

I walked outside and saw Mario in front of a red pipe with a bunch of words I couldn't make out from over here, so I headed over to see what was going on.

Y/N: What's going on here? Mario, did you do something again?

Mario: Hey! Why does everyone blame me for everything!?

Y/N: Because most of the time it's usually you, man.

Mario: Oh yeah.

Y/N: Anyway... [Reads the words on it] Highschool DXD?

Mario: You can read that?

Y/N: Yep. It seems this pipe goes to the DXD world.

Mario: Hmmm. Let's go in!

Y/N: Why?

Mario:

Mario: Why not? [Jumps into the pipe]
 
Y/N: Ugh... It's just going to be one of those days. Welp, better make sure he doesn't do too much chaos and destruction again. [Jumps into the pipe as well]
 

3RD POV:
Somewhere in the ORC club:
 
Riser: Ahhh, Riser's haven't been to the human realm in a while. I've come for you, Rias, My Love.
 
Issei: Who's this Guy?
 
Grayfia: This is Riser Phoenix-sama. A pure-blooded, high-class devil and the third son of the Phoenix family.
 
Issei: Phoenix Family?
 
Grayfia: He's also the fiancé of the Gremory family's heiress.
 
Issei: Her fiancé?! Don't tell me...
 
Grayfia: That is to say, he's engaged to Lady Rias.
 
Issei: E-Engaged?! (No! It can't be?!)
 
After everyone settled down following the introduction, Riser sat on one of the couches while he had his arm around Rias as Akeno brought him some tea.
 
Riser: My, Rias's queen prepares quite delicious tea!
 
Akeno: [Bows] Thank you for the compliment.
 
Issei: (This disgusting guy is her fiancé?!)
 
Rias: Cut it out already. [stands up] Riser, I told you last time. [Looks to Riser] I don't intend to marry you.
 
Riser: But, Rias, I thought your family was with its back to the wall, so you're in no position to be this selfish.
 
Rias: I'm not going to bring my family down; I'm going to take a husband. But I will marry someone I want to be with, and that someone isn't you!
 
Riser: You say that, but the entire Devil world struggles to preserve the lineage of pure-blooded devils after the war made them a rarity. You do know that this marriage was arranged by our Fathers for the common good.
 
Rias: My father, elder brother, and other family members are all rushing too much. I won't say it twice, Riser. I'm not going to marry you.
 
Riser stands and places his hand on Rias' chin and says,.
 
Riser: You know Riser is the Face of the Phoenix Family; I will not have you, Sully, my Honor. I'll take you back to the underworld. Even if it means burning all of your servants to death!
 
As he said this, they locked eyes emanating their aura. Grayfia stepped in and said.
 
Grayfia: Milady, Riser-Sama... 
 
Suddenly a green pipe appeared on the floor, surprising everyone in the room.
 
Issei: What is that? 
 
Just then, Mario jumped out of the pipe, landed on the floor.
