After two weeks has passed, Rias and the rest of the members of his peerage were all ready to face off Riser and his peerage in the Rating Game.

We now see Y/N getting up from bed after his afternoon sleep, eating a little snack to build up a little energy in his body, walks out of his house, and gets on his Blue Spader as he puts on his helmet.

Y/N: All right... Let's do this. 

Y/N turns on the engine and revs up his bike all the way to Kuoh Academy for the Rating Game at late night.

Y/N: I'm so glad I'm not late every time I go to school thanks to my bike.

(Old School Building)

(Occult Research Club Room)

Everyone was already at the club arming and preparing themselves for the Rating Game against Riser.

Issei: It's not surprising that you ladies are so composed. 

Then they all turn their heads and see the student council president, Sona Sitri, and the student council vice-president, Tsubaki Shinra, walking in the club room.

Sona: Excuse us.

Rias: Good evening, Sona.

Akeno: Welcome~!

Issei: The student council president and vice-president...?

Y/N: Why are they doing here?

Rias: Rating Games are broadcast to the members of both families. They are responsible for it.

Issei: I see.

Sona: I volunteered for the task. It's your first game, after all.

Rias: I'll show you a fight that won't insult our rivalry.

A magic circle appeared behind them and Grayfia appears out of the magic circle.

Grayfia: Everyone, are you prepared?

Rias: Yes, anytime.

Grayfia: When it's about to start, you will be teleported to the battlefield. 

Issei: Battlefield?

Akeno: An alternate space created just for this game. It's disposed of after each game, so you can run wild all you want.

Inner Issei: W-Wild, huh?

Sona: I will be going back to the student council room to manage the broadcast. I wish you the best of luck, Rias.

Rias: Thank you, but make the broadcast fair, okay?

Sona: Of course. I do not expect an even match against him, however. 

Sona and Tsubaki then walked away and walked out of the club room.

Grayfia: By the way, the demon lord Lucifer will be watching this fight as well.

Rias: I see... My brother is also...

Issei: D-Did you just say "brother"? Did I hear it wrong?

Y/N: No, you heard it right, Issei.

Kiba: Her brother is the demon lord.

Issei: T-The demon lord?! Your brother is the demon lord?!

Rias: ... Yes.

Kiba: Sirzechs Lucifer, known as the Crimson Satan. That's her brother. Sirzechs-sama succeeded the previous demon lord Lucifer-sama that passed away in the war.

Asia: So that's why the President became the heiress of the Gremory family...

Y/N: So that's what it was.

Toshiaki: ...

As everyone kept waiting, a big red magic circle appeared inside their club room.

Grayfia: It's about time.

Rias: Well then, let's go.

Everyone stands up on their feet and walks over to the magic circle and then they stand on top of it as they were all starting to disappear one by one.

Y/N: I've got a feeling... this will work out!

They appeared out of the circle, but as they look around, they see that they're still at the Occult Research Club room.

Issei: Huh?

Asia: Nothing changed... 

Issei: Did the teleportation fail? Did I screw up again?

Toshiaki: No, it did work.

Grayfia: Everyone... I am Grayfia, a servant of the Gremory family, appointed judge between the Gremory and Phenex families. Taking Rias-sama and Riser-sama's opinions into consideration, we prepared a replica of Kuoh Academy, the school Rias-sama attends in the human world, as the battlefield. 

Y/N: So it's a replica for our battlefield, huh?

Rias: Take a look outside.

Y/N: Y-Yeah.

Y/N opens the window and him, Toshiaki, Issei, and Asia were all surprised that the sky was completely different and weird.

Asia: The sky is...

Kiba: We're in an alternate universe. 

Akeno: With a replica of the entire school in it.

Issei: J-Just how amazing are the demons' powers?

Y/N: You can say 100%... No... 1000% amazing.

Grayfia: Both parties have been teleported to their main base. Rias-sama's base is the Occult Research Club room in the old schoolhouse. Riser-sama's base is the principal's office in the new schoolhouse. Thus, pawns can be promoted when they manage to invade the enemy's schoolhouse.

Issei: So I just need to enter the new schoolhouse and the promotion will make me as powerful as a queen, the strongest piece!

Akeno: Ara ara~ It won't be that easy.

Issei: Huh?

Kiba: It also means their pawns can be promoted if they enter this building. You should expect the main base to have the strongest defense. 

Issei: You have a point...

Koneko gives Y/N, Toshiaki, Issei, and Asia a small energy orb.

Y/N: What is this?

Rias: This is how we'll communicate on the battlefield.

Toshiaki: So it's like a transceiver. 

Then they inserted the small orbs in their left ear.

Grayfia: The game begins now.

(Principal's Office)

Riser: They might be too weak for you, but don't hold back. Crush them completely. The only reason we're playing this silly game is to break down that crimson-haired girl's pride... And... Beware of Blade and Garren, when it comes to the Undead, they're bad news and dangerous. So be careful. Do whatever you can with them and don't let those two get close to me. Got it?

(Occult Research Club room)

Y/N: So, what's your plan, Rias-senpai?

Rias: The enemy's main base is the new schoolhouse. It'd be quickest to across the schoolyard, but... 

Toshiaki: We'd be in plain sight, right?

Rias: Indeed, it's too risky.

Issei: Then maybe approach the new schoolhouse from the back across the track field?

Rias: They are probably expecting that. I expect a few of their nimble rooks and knights to be placed around this clubhouse.

Akeno: It's a classic but foolproof tactic.

Kiba: President, why don't we take the gym first, which is near both the old and new schoolhouse? It's pretty close to our base and would need help keep the enemies in check. 

Rias: The gym is like the center of a chessboard. Taking it first would give us a tactical advantage. It's decided then. It's indoors, so a rook's power would be better suited than a night's mobility.

Asia: Fighting is difficult, isn't it...?

Issei: Well, we just need to believe in the president and follow her orders.

Y/N: Anyway, we just have to keep fighting and win. We can't give up and we must have faith in ourselves. And I hope Rias-senpai had faith in all of us. I can feel it.

Asia: You're right.

Rias: First, we need to secure the defensive line. 

Rias looks at Kiba and Koneko.

Rias: Yuuto, Koneko, go set up traps in the forest. 

Kiba: Yes, ma'am!

Koneko: Roger. Come, Shiro.

Koneko then summons her familiar.

Kiba: We'll be going, then.

Rias: *looks at Akeno* Akeno, once the traps are set, use illusionary magic on the forest and the sky above it.

Akeno: As you wish.

Rias: *looks at Y/N and Toshiaki* And Y/-

Y/N: Ahem. Say no more, Rias-senpai. Do you still remember our conditions, Rias-senpai?

Toshiaki: We know where this plan is going. So don't order us around as you owned us. You haven't forgotten about our promise, haven't you?

Rias: O-Oh, right... I almost forgot about that... All right. Do whatever you can, then.

Y/N: We know about the plan, so we know what to do. But don't worry, we're not gonna lose this Rating Game. You can count on us.

Y/N and Toshiaki then left the club room.

Rias: *sigh* I hope so...

(Timeskip by another DxD meme)

(Outside)

Y/N and Toshiaki were laying back on a tree branch taking a small snooze while they were watching over any nearby enemies coming over.

Y/N: Hey, Tachibana-san. Aren't we supposed to be aware of the enemies coming by? 

Toshiaki: We're just taking a little break. The others are probably still setting up the traps.

Y/N: Are you sure? Maybe KFC and his peerage have already made their first move.

Toshiaki: Let's just wait and see.

Y/N: ... Hey, Tachibana-san.

Toshiaki: What?

Y/N: It's... It's always been on my mind lately.

Toshiaki: What is?

Y/N: Well... The peerage... Riser's peerage... They all looked afraid and scared when we introduced ourselves as Blade and Garren. And I noticed Riser clenching his fist when he was talking to us. I really don't know why.

Toshiaki: ... So you noticed about it too, huh?

Y/N: *looks at Toshiaki* What do you mean?

Toshiaki: It's not just Phenex and his peerage... Rias-san, Himejima-san, Kiba-kun, Toujou-chan, and the Student Council, they all had the same frightened reaction when they looked at us...

Y/N: They're afraid, too?! Why?!

Toshiaki: I don't know... But when this game is over, we have to know why they are all afraid.

Y/N: You're right... Let's keep that in mind.

Rias: Kenzaki-kun, Tachibana-kun, can you two hear me? Have you two prepared your plan?

Toshiaki: Yeah, we are.

Rias: Are you sure you know what you're doing, you two? I know I have to follow your conditions, but...

Y/N: We'll be fine. We know what to do. Don't worry about it.

Rias: ... Okay. I believe in you. Good luck out there.

Y/N: Thanks... Hm? Wait a minute...

Toshiaki: *looks at Y/N* What is it?

Y/N: If my prediction is correct, I'd say Akeno's lightning attack should hit the gym right about... now.

BOOOOOM!!!

Further, in the distance, explosions were heard.

Grayfia: Riser-sama's three pawns and a rook, knocked out.

Y/N: Yup, I called it.

Toshiaki: Looks like Hyoudou and Toujou-chan made it out of the gym on time. It's all according to Rias-san's plan.

Y/N: All right. Let's meet up with Kiba around the track field and annihilate the enemies in the area after he finished dealing with Riser's goons inside Akeno's barrier as the next plan. 

Toshiaki: Yeah.

Y/N and Toshiaki jumped off the tree and then they quickly ran towards Kiba's location.

(Issei/Koneko)

Issei and Koneko were hearing Rias' instructions about the next phase.

Rias: The real challenge begins now. We're still outnumbered It'll take some time for Akeno to be ready to fire another shot. We'll join you on the battlefield as soon as she recovers. Until then, both of you should start getting ready for the plan's next phase. 

Issei: The next phase is...

Koneko: We're to meet up with Yuuto-senpai around the track field, and annihilate the enemies in the area.

Issei: I wonder if Kiba is all right?

Koneko: You're not worried about your own best friend, Kenzaki-senpai?

Issei: ... No. Not even a bit. And... he's not my best friend anymore... Not ever again.

Koneko: Issei-senpai...

Issei: Anyway, knowing Kiba, he's probably doing just fine with a handsome smile. Koneko-chan, we should go, too.

Koneko: Don't touch me.

Issei: D-Don't worry. I'm not going to use it on a teammate.

Koneko then walks ahead.

Koneko: Still, that is a terrible technique.

Issei: *sweatdrops* Looks like she's seriously hating me for that... W-Wait, Koneko-chan!

Issei catches up to Koneko and they were both heading for the athletic field until... a magic circle appeared below Koneko and then exploded sending Issei flying and rolling on the ground.

Issei: Argh! Koneko-chan!

Rias: Koneko! What happened to Koneko?! Respond, Issei!

Issei runs up to Koneko and then he holds her in his arms. Her clothes were completely shredded and destroyed from the explosion.

Issei looks up and sees Riser's queen, Yubelluna hovering in the air.

Issei: Damn it! Was that Riser's queen?! 

Koneko: I'm sorry...

Issei looks back down at Koneko.

Issei: Koneko-chan!

Koneko: I wish I could've been of more help to the President...

Issei: Don't worry! Asia will heal your injuries in no time-?!

Koneko: Argh...!!!

Koneko then starts fading away in blue pixies as she yells in pain and then disappears.

Grayfia: Rias-sama's rook, retired.

Issei stands up and looks up at Yubelluna.

Issei: Damn it! How dare you do that to Koneko-chan! Come down here! I'll fight you!

Rias: Calm down, Issei. Those who are rendered unable to fight are teleported outside and treated. Koneko didn't die. You need to stay calm. 

Issei: But...!

Yubelluna: Give it up, boy. No matter how hard you fight, you can't win against us.

Akeno appears.

Akeno: Ara ara~ 

Issei: Akeno-san!

Akeno: *looks at Issei* Issei-kun, I'll deal with her, so hurry along. You need not to worry. I will avenge Koneko-chan with all my might. 

Issei: Okay, Akeno-san!

Issei quickly runs off towards the athletic field.

Yubelluna: I wanted to fight you someday, Priestess of Thunder. 

Akeno: Ara ara~ I am quite honored, Bomb Queen.

(Issei)

Grayfia: Riser-sama's three pawns, retired.

Issei: Three?!

As Issei kept running, he then was pulled aside by someone. 

Kiba: *smiles* Hey.

Toshiaki: Jeez, what took you so long, Hyoudou?

Y/N: I heard what happened to Toujou-san.

Issei: Oh, it's you guys! Wait, those three just now...

Kiba: Thanks to Akeno-san's barrier, it was pretty easy to beat them all by myself.

(Later...)

Y/N, Toshiaki, Issei, and Kiba were now hiding inside the storage room.

Issei: Sorry, but Koneko-chan was...

Kiba: We heard. She's usually not that outgoing, but she seemed pretty excited today. It's a pity.

Y/N: We all thought everything is all according to plan, but... I didn't know this would happen.

Issei: Don't drop the flag now, Kenzaki. Let's win this, no matter what! 

Y/N: *smiles* Yeah.

Kiba: Of course.

Rias: Yuuto, Issei, Kenzaki-kun, Tachibana-kun, can you hear me? Asia and I will launch a surprise attack on their main base, so distract as many enemies as possible to buy us some time.

Issei: A surprise attack?! 

Rias: I don't have any other choice. The plan was to wait for Akeno to recover and destroy each building individually, but that won't work since he's already brought out his queen. 

Kiba: But, President, it's way too risky for the king to leave the base! 

Rias: The enemy must be thinking the same. That's what I'm going for. Phenex's body might be immortal, but his mind is not. If I deliver a strong attack enough to make him lose his fighting spirit, I can win. I'll break down Riser's spirit myself!

Y/N: His body is immortal, but his mind is defenseless... I see! Now I get it! I know what to do now!

Issei: *looks at Y/N* What is it, Kenzaki?

Y/N: I finally know what to do now! Of course! Why didn't I think of that?! Every enemy has a weak spot! 

Kiba: You have an idea, Kenzaki-kun?

Toshiaki: What's your plan?

Y/N: I finally figured out how we can beat Riser and make him quit the game. We'll just have to follow Rias-senpai's plan and I'm going to get the chance to do my thing to Riser.

Kiba: What are you going to do?

Y/N: You'll just have to wait and see.

Rias: Well, I can't really argue with you if you have a plan. I hope you know what you're doing, Kenzaki-kun.

Y/N: Don't worry, Rias-senpai. My plan... is a full proof plan.

To be continued
