(Next Day)

(Y/N)

Currently, we now see Y/N, Toshiaki, Issei, Asia, and Kiba walking together to the old school building.

Kiba: President's worrying, huh? I suppose it's some internal affair of the Gremory family.

Toshiaki: An internal affair?

Y/N: What do you mean?

Issei: Would Akeno-san know something about it?

Kiba: She is her right-hand woman, so she probably does.

Kiba stopped walking and then he felt a strange presence as Y/N, Toshiaki, Issei, and Asia stopped walking and looked at Kiba.

Issei: What's wrong?

Y/N: What is it, Kiba?

Kiba: I can't believe I noticed it only now. What is going on?

(A few minutes later)

Y/N, Toshiaki, Issei, Asia, and Kiba went inside the Occult Research Club room.

Issei: Hey, what's up?

As they went inside, they all see Rias along with Akeno having a conversation with a girl with gray hair while wearing a maid outfit.

Issei: Eh?! Grayfia-san?!

Toshiaki: Gray-who?

Y/N: *looks at Issei* Hey, who is that woman?

Issei: *looks at Y/N* She's the maidservant of the Gremory family, Grayfia. I first met her last night when I was about to have my first time having sex with the President.

Y/N: Oh, I see... 

Toshiaki: Now I get it...

...

...

...

Y/N/Toshiaki: *looks at Issei* HUH?!?!?!?!?!?

Grayfia walks up to Y/N and Toshiaki.

Grayfia: Nice to meet you, Blade, Garren. My name is Grayfia, a servant of the Gremory family. *bows* Pleased to meet you.

Y/N: Y-Yeah, it's nice to meet you too, Grayfia-san.

Toshiaki: Whatever.

Rias stands up.

Rias: Looks like you're all here.

Y/N: *looks at Rias* Hey, Rias-senpai. What brings Grayfia-san here to our club room?

Grayfia: *looks at Rias* Milady, should I talk to them?

Rias gestures at Grayfia to let her talk instead of her servant maid.

Rias: The truth is...

As Rias was about to speak, an orange magic circle set on fire appeared inside the club room and it appears to be a teleportation magic circle and then a man with blonde hair wearing a red suit comes out of the circle.

Kiba: Phenex...!

Phenex: I haven't been to the human realm in a while.

Phenex turns around and looks at Rias.

Phenex: I've come for you... Rias, my love.

Rias: ...

Issei: W-Who is this guy?

Grayfia: This is Riser Phenex-sama. A pure-blooded, upper-class demon and the third son of the Phenex family. 

Y/N: Phenex family?

Grayfia: He's also the fiance of the Gremory family's heiress apparent. 

Issei: The Gremory family's heiress apparent?! You don't mean...!

Grayfia: That is to say, he's engaged to Lady Rias.

Issei: E-Engaged?!

Y/N: Seriously...?

Rias: ...

(Small Timeskip by a Highschool DxD meme)

We now see Riser having his tea served by Akeno while he was sitting beside Rias playing with her red hair and harassing her legs.

Riser: My, Rias' queen prepares quite delicious tea.

Akeno: *bows* Thank you for the compliment.

Inner Issei: This disgusting guy is her fiance?! 

Inner Y/N: So that's Rias-senpai's fiance, huh? But... I got a bad feeling about this guy...

Inner Toshiaki: This Riser guy... I feel disgusted now when I'm with him in the same room...

Rias slaps Riser's hand away and stands up.

Rias: Cut it out already. Riser, I told you the last time. 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. 

Riser: The entire demon world struggles to preserve the lineages of pure-blooded demons after the last war made them a rarity. Our fathers arranged this marriage 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 up and holds Rias' chin.

Riser: You know, Rias, I am the face of the Phenex family. I cannot have you sully my honor. 

Rias: ...

Issei: President! 

Riser: I'll take you back to the underworld. Even if it means burning all of your servants to death.

Y/N: I wouldn't go there if I were you, buddy.

Rias and Riser look at Y/N.

Rias: Kenzaki-kun...?

Riser: Huh? Who are you?

Y/N: *points at Riser* Let me tell you this, I don't give a fuck if you're the face of the KFC fried chicken family or your KFC fried chicken honor, but... you shouldn't make a bad scene in front of the maid of the Gremory family.

Riser: *pissed* F-Fried Chicken...?

Grayfia: Please calm down. Milady, Riser-sama, as I am here on Sirzechs-sama's orders, I do not intend to stand idly by. 

Riser: *sigh* When it's you, the mightiest queen, saying that, even I am scared.

Grayfia: He predicted this might happen. As such, I have been charged to carry out last resort measures if no agreement is reached. 

Rias: Last resort? What do you mean, Grayfia?

Grayfia: If you insist on your position, you're welcome to settle the issue with Riser-sama through a Rating Game. 

Toshiaki: Rating game? 

Y/N: Where have I heard that...?

Issei: ... I see! The student council president was saying something like that! 

Kiba: It's a game that resembles chess where upper-class demons fight using their servants. 

Y/N/Toshiaki/Issei: Chess?

Akeno: That is why our powers are linked to chess pieces. Why we're called Evil Pieces.

Issei: I see...

Riser: I've played the game many times and won many times as well. You're not even an officially qualified player, let alone have any experience

Akeno: Originally, only seasoned demons were allowed to participate in a Rating Game. 

Y/N: Then she's at a real disadvantage, huh?

Akeno: That's right.

Toshiaki: That's going to be a problem...

Koneko: It's getting worst. 

Riser: *looks at Rias* Rias, just to make sure, are these all your servants?

Rias: What if they are? 

Riser: Hahahaha! 

Riser snaps his finger and then another orange magic circle appeared and fifteen girls and women came out of the circle.

Riser: I have fifteen! In other words, a full set of pieces. 

Y/N: *sweatdrops* But... why are they all girls? I don't see a single guy in your peerage. Are you some kind of pervert?

Toshiaki: *sweatdrops* Riser really has good taste in girls, but... this is too much. Even the lolis are in your peerage... if they are legal, of course.

Issei: Beauties?! Fifteen beautiful girls?! Unbelievable!

Y/N: Well, at least Issei has finally disagreed on what he likes for once.

Toshiaki: I agree.

Issei: ... *cries* What a true man!

Y/N/Toshiaki: *looks at Issei* Are you serious, you dumbass?!?! 

Riser: *sweatdrops* H-Hey, Rias... Your servant is crying out loud while looking at me...

Rias: *sweatdrops* Forming a harem is his dream...

The girl with blonde hair speaks.

?????: That's creepy.

Toshiaki: You can say that again. Just ignore him. He's a pervert and a loser, after all.

?????: ...

Toshiaki: ...

Toshiaki and the blonde-haired girl then looked at each other.

Toshiaki: I can't believe we both agreed on something for the first time even if we don't know each other... I'm surprised.

?????: Y-Yeah, I'm surprised you agreed with me, too...

Toshiaki: ...

?????: ...

Things were getting awkward between the two of them.

Toshiaki: So, uh... It was nice talking to you, then...

?????: I-It was nice talking to you, too...

Riser: Hahaha. Now I see. 

Riser turns to his queen.

Riser: Yubelluna.

Yubelluna: Yes, Riser-sama.

Yubelluna walks up to Riser and then he pulls Yubelluna closer to him and kisses her.

Rias had a disgusted look on her face after she saw Riser kissing another girl in front of her. 

Y/N: W-What the hell...?!

Toshiaki: And he kissed that woman in front of her fiance, too...?! What is he thinking...?!

Riser looks at Issei as he starts groping on Yubelluna's breasts.

Riser: You'll never be able to do things like this, you lowly imp.

Issei: S-Shut up! I can tell you'll flirt with other girls even after marrying our President, you promiscuous fried chicken shit! 

Riser: You lowly imp... Don't you know your place? 

Issei: Like I care!

Rias: Issei, stop.

Issei: All I'm aware of is my position as the President's servant! Nothing more, nothing less!

Issei summons his Boosted Gear.

Rias: Issei...

Issei: We don't need a stupid game! I'll bring all of you down right here! 

Boost!

Asia: Issei-san!

Y/N: Don't, Issei!

Riser: Mira!

Riser's pawn, Mira jumps out of the crowd and blocks Issei's way.

Issei: This small girl...?! I can't really attack her...

Y/N: Issei, watch out! Don't be fooled by her!

Issei: Eh?

Issei looks at Y/N then he looks back at Mira only to see her that she's already close to Issei ready hit him on his gut but Y/N made it on time and catch the girl's staff to protect Issei. Y/N placed his hand on Mika's stomach and then he pushes her back to the crowd with one hand.

Y/N: Oooo~...!

Y/N: WATCHAA!!!

Mira: Argh...!

One of the women in the crowd catches Mira as everyone in the room was shocked at how strong Y/N was.

Issei: T-That's awesome! Thanks, Kenzaki!

Y/N: You can't thank me later. Be careful, Issei. You almost got yourself hurt by her. These girls are really strong. They are over your level.

Issei: Over my level...?

Inner Issei: All of these girls... are stronger than me...?

Toshiaki: That's really awesome...

Kiba: What incredible hand strength...

Koneko: And he pushed her back with one hand.

Akeno: *smiles* Ara ara~ That's really amazing, Kenzaki-kun.

Riser: Oh? You're not so bad yourself, you lowlife. So, who are you?

Y/N: *looks at Riser* I'm only gonna tell you this once. So you better remember me. I'm Y/N Kenzaki...

Y/N pulls out his Blay Buckle and shows it to Riser and his Peerage.

Y/N: ... Kamen Rider Blade.

The Riser peerage was shocked that Y/N was Blade while Riser found it interesting.

The Riser Peerage: ?!?!

Riser: Oh? So you're Blade, huh? I heard a lot about you. You look different than I expected.  

Y/N: What's the supposed to mean?

Riser: I mean, why would God give the first and one of the most powerful Sacred Gears in history to a weakling like you? I really don't get it.

Y/N: *pissed* What the hell did you say about me?

Riser: By the way, where's the other one? I heard Rias found another one who also possessed the power of one of the belts, too.

Toshiaki steps up and stands beside Y/N.

Toshiaki: I'm here.

Toshiaki pulls out his Garren Buckle.

Toshiaki: I am Toshiaki Tachibana... Kamen Rider Garren.

The blonde-haired girl's eyes were widened after she heard the name "Garren".

?????: No way... That man... is Garren...?

Riser: The warrior of the lightning spade, Blade... And the warrior of the burning diamond, Garren... *smirks* Now this is getting interesting. 

Y/N notices that the girls on Riser's peerage were shaking their bodies a little and their faces were a little scared.

Inner Y/N: Why do look they all look so afraid of me and Tachibana-san...? Is it because I'm Blade...? Or is it something else...?

Riser: I never thought that lowlifes like you two can wield the power of the undead. Heh. You don't stand a chance against me for weaklings like you two. I don't even have to worry about it.

(A/N: Wait until you see and fight against the Joker Undead, you KFC fried chicken bastard!)

Toshiaki: *pissed* Okay, now you're pissing me off.

Y/N: *pissed* It's on now, KFC fried chicken.

Rias: That's enough, Kenzaki-kun, Tachibana-kun. Please step back.

Y/N: ...

Toshiaki: ...

Y/N and Toshiaki stepped back and Rias looks at Riser.

Rias: ... All right. Let's settle this with a Rating Game. 

Grayfia: Understood. 

Rias: Riser... I swear I'll blast you away!

Riser: I'm looking forward to it, Rias, my love. We'll meet again for the game, then. 

Riser along with his peerage then disappeared from the magic circle. 

Y/N: We'll see about that, Riser Phenex... I'll show you what Kamen Riders can really do.

To be continued
