Rias and the rest have completely their training and now they are ready to face Risee and his household so Rias will not have to marry Riser.

They teleported to the Rating games and they appear but this confuses Isses as they see they were teleported into the Occult research club as he looked around and said.

Issei: Um why are we at our club?

Rias: (smile) It may look like our club but look outside.

Issei did so as he look out of the window and was shocked to see the sky completely different, showing a purple galactic like sky above them.

Issei: (shocked) Wow! This is soo cool!

Asia: (surprised) So this is what the Rating game looks like.

Akeno: (smile) Well we can make the battlefield to be anything we want, in this, its the copy of our school.

Y/n: (smirk) Huh nice. This place gets a gold star for good digital and other things.

Akeno let out a giggle and then a voice of Sona can be heard.

Sona: (speaker) Rias Household has enter the Game, the Rating Game can begin now.

Issei: Was that Sona?

Koneko: She and Tsubaki must be the announcers of the Rating Game.

Y/n: (smirk) Make sense. So got a game plan here Rias?

Rias: (smile) I'm glad you ask. If I'm right, Riser and his house hold must be being held inside the school. We need to reach to the school and defeat him so we can end the game. My plan is simple, Y/n, Akeno and Koneko will scout ahead and see what you three can find. The rest of us will stay here and call us once you see something.

Y/n: Sure thing Rias. Be back possibly a long while, Issei try not to do anything stupid while we're gone.

Issei: Just go alright!

Y/n: (smirk) Sure thing, bye~!

Then the trio walked off and leave the room while Rias smiled while Issei sees this and gets a bit jealous while outside we see a mysterious figure watching them as the figure goes after Y/n so he can complete his job.

(Later)

We see Striker is seen flying through the sky, searching for anything while Akeno's tiny demon creature we're on the ground and Koneko's kittens named Shiro is seen leaping through tree branches as three of Y/n, Koneko and Akeno's familiar scout ahead while we see the trio standing and waiting for their return.

Y/n: (smile) Gonna say Koneko, your familiar is one adorable kitten.

Koneko: (little blush) Th-Thanks.

Akeno: (giggle) Don't be like that, he's being nice.

Y/n: So how powerful you thinm Risers household are? They can't be that strong right?

Akeno: Well we maybe outnumbered but I'm sure we can take them on.

Y/n: (smile) Yeah. Your right.

Then Striker fly back and landed on Y/n's arm as Striker hawks like he is telling him something.

Y/n: Seems Risee is splitting off his members to different points of the rating game.

Akeno: Right, I'll inform Rias.

Akeno does so while Striker noticed something and glare at something behind Y/n which he noticed and turn around and sees what looked like a fog rolling in as Akeno and Koneko turn and see it.

Akeno: Where is this fog come from?

Koneko: That's not supposes to be here.

Y/n:.........You two go. Looks like this one is my fight.

They turn to Y/n and soon agree as they head off and now it was just Y/n and the fog. Then he sees a figure appear in the fog as the figure came out of the fog. The figure was wearing all cloak with a hood over his head while wielding what seemed like a chain mace as he spines it around and around.

Y/n: And you are?

Mist: They call me The Mist, a being who make others dissappear within the white, cloudy, fog.

Y/n: So your some sort of a ghost or a spirit?

Mist: It doesn't matter what you call me, because you will be gone either way.

Y/n: (smirk) So your apart of Riser's house hold or something?

Mist: No. I was hired by him to kill you.

Y/n: (thought) Well not only he's a jackass but a fucking cheater.

Y/n: (smirk) Listen here, we can do this the easy way, or the hard way.

He then summon his The Screams of Triumph battle axe while he gives Mist a smirk while he just let out a chuckle and said.

Mist: No matter how strong you are, you can never defeat...the Mist.

Then a huge fog was poured towards Y/n and he was hit by them. He was now surrounded by fog as he look around and sees figures around him as they appear and disappear.

He looked around, trying to catch him and when he thinks he's coming towards him, he swings his axe but only for the figure to poof away.

Then he turn only to dodge the mace as it slammed to where Y/n was standing. He land on the ground and looked around as he swing his axe around at the figures but they poof away over, over, and over which made Y/n a bit frustrated.

Y/n: Come out and face me like a man you coward!

Mist: So be it.

Suddenly he turn and gets hit by the incoming mace as he stumbled back. Then a chain mace wrapped around his leg and he was pulled into thr air and slammed hard onto the ground. He then sees Mist leaping over to stab at him but he slice the chains with his axe and then swings his axe but he poof into air.

Y/n: Fuck!

Mist: Now you see what you are facing with! You can never defeat me, I can control the fog around me. There is nothing you can do now.

Then Y/n had an idea as he swap his axe to his Spear as he swings it back while he thinks to himself.

Y/n: (thought) This might be crazy but here goes nothing!

He opens a void while at the same time he stabbed his spear onto the ground and seconds later the void starts to quickly suck everything into the void, including the fog as the fog gets suck through the void.

Soon the fog was clear and there was Mist as Y/n smirked and then closes the void and open another one as he rushes over, picks up Mist and then tosses him into the Void as he goes through and then Y/n shuts the void.

Y/n: (smirk) Hope you enjoy the hot boiling lava pool, You gonna need it!

He let out a sigh of relief as he look around to see he is still in the forest as he heads off while he thinks to himself.

Y/n: (thought) Well, better go and help out Rias and eveyeone else. Hopefully they are doing alright without me.

(Soon)

He burst out of the bushes and arrived at the school itself and sees that Rias and the others were busy as holes can be seen around, cost by explosions as Y/n says to himself.

Y/n: Looks like they have busy. Hopefully I'm not too late.

Rias: Riser stop!

He looked over at the roof to see Rias as he sees that something bad is happening so he rushes over into the school building, rushing up the steps and then break through the roof to see Risee beaten the hell out of Issei.

He turns to see only Rias and Asia are the last once left, realising that Koneko, Akeno and Kiba must have been eliminate during the battle.

Riser: (smirk) This is where you will die!

Rias: ISSEI!!!

Riser fist burst into flames, ready to end Issei but then Y/n grabs his arm and then he tosses Risee back, slamming him into the wall while Issei fell onto the floor and gets up to see Y/n as he gives Riser a serious face.

Riser slowly gets up and sees Y/n as he gets angry and called out.

Riser: (anger) I thought you will be dead!

Y/n: By a Bounty hunter you sent to kill me? Tch, nice try chicken face.

Riser: (anger) Fine! I guess I have to kill you myself and then I will mqrry Rias for sure!

He then smirked which Riser noticed as Y/n tells him.

Y/n: (smirk) Rias would never love you, you know why? Because she can love anyone she can want and I can respect her. She deserves someone who is kind, brave, caring, understanding and most importantly of all....someone to be with her no matter what. That's what true love is.

Rias: (little blush) Y/n.

Y/n: But....what I don't like is someone like you forcing someone to marry them even though they don't like. To them, they are a huge piece of shit, and they must be punished.

Then there was a huge dark energy shot out as Y/n changed into his first armor in front of Riser as was shocked to feel soo much power.

Y/n: Now then Riser. Are you ready to meet your punishment of being a huge asshole.

Riser: (shocked) Th-Th-That. I'm not gonna be scared by the likes of you! Show me what you got you piece of shi-

Suddenly Y/n slammed his hand at Riser, slamming him into the wall and forming a huge crack around him. Riser was shocked and didn't have time to react as Y/n's red eyes glare at Riser and then he strike a powerful blow at Riser over and over again.

Riser gets even more beaten up more Issei as Y/n keeps punching him onto one punch cost him to crash through the wall and land hard into the class room.

He slowly get up and look up to see Y/n gone. He then hear some foot steps around him as Riser grind his teeth and burst his two hands into flames, while the flames revealed Y/n behind him.

Y/n: Boo.

He quickly turn and he was slapped very heard, sending him flying and crashing through the classroom wall as he slowly gets up. He then shoots fire into the classroom while he laughs.

Riser: IS THAT ENOUGH FOR YOU!!!

Y/n: No. What about you?

Suddenly Y/n rushes out of the flaming classroom, pulled back his fist and striking a powerful punch which sent Risee flying as he slammed into the floor and sliding on the floor while Y/n appear as he punch and kick him across the school.

Explosions can be seen all around the school as Rias, Asia and Issei watched in shock. This goes on until Riser burst through the wall and land hard outside of the school. He slowly sat up and looks over to see red eyes glowing within the darkness as Riser was immediately struck in fear as he crawl backwards.

Riser: (scared) N-Nonononon! Get back! Stay back!

Y/n came out of the darkness as he walk slowly towards him while glaring at him as Riser shoots fire at him but they just bounce off of him as Y/n approaches him and glare down at him.

Riser immediately tru to get up but his feet got stumped by Y/n who yell while he turn to see Y/n pulling back his fist, ready to give him the most powerful punch he get. Riser shakes in fear as he try to break free but there was no use as Y/n swing his fist towards him but he called out.

Riser: (Scared) STOP!

He immediately stop his fist which he a huge blow while Riser sees Y/n's fist was inches to his face as Risee called out in terror.

Riser: (scared) Okay, okay I surrender! I surrender, just please don't kill me!

Y/n stare at him and remove his fist from his face as he stood over him and then ask him.

Y/n: You'll leave Rias alone and never bother her every again.

Riser: (scared) I swear! I'll stay far away from her just please don't hurt me!

Y/n: Pfft.....what a chicken.

Sona: (speaker) Risee as surrounded the match, which means Rias house hold wins the Rating game.

Rias was surprised how they won as Y/n remove his feet from Riser and then walk away as Riser lay there in fear while Rias came down and then hug Y/n.

Rias: (smile) We won! We won!

Y/n: (chuckle) You sound like we're never gonna win.

Rias: (smile) Still, thank you Y/n. I really appreciate with it.

Y/n nodes to her while his helmet disappeared as Y/n smirked at her and then ask her.

Y/n: (smirk) So you gonna go and find your true lover or what?

Rias: (giggle) I've already have.

She then kiss Y/n on the lips which Y/n kisses her back while Yubelluna and Risers peerage approaches Riser and seeing him scared and shaking all around which disappointed them but either way, they take Riswe away while Rias and the others celebrated their victory as they return back home and celebrate their win.
