Issei was Riding his Bike through the Streets after trying to make Contracts with A Few people but none of them believed him since and I quote "Devils don't ride Bikes" and he's already In A Crappy mood as is.

Issei:  Stupid People, Not Thinking I'm A Devil... I'm A Devil! The only person who even took A Job from me was that Man dressed up as A Woman. That's not what I was asking for.

???: Well, well, well, isn't Little Hyoudou having A Little trouble?

Issei: Vali.

Just then the Heir to the Lucifer family walked out as he Looked at Issei with A Smug smile.

Vali: So no new Contracts Huh?

Issei: I don't know, any more douche moves?

Vali: Yeah, How's that Client of yours? The Man dressed up as A Magical girl.

Issei: I don't know, How that Broken Ego.

Vali: ...

Issei: ...

Vali: ...

Issei: ...

Vali: You Know I am thinking that The only reason why you won last time is your List for Big Boobs.

Issei: HEY! I LOVE BOOBS OF ALL SIZES!

Vali: Yeah, yeah, I Know, You're A Pervert.

Issei: SHUT UP!

Vali: Yeah, You are.

Issei: What do you even want?

Vali: I want to fight you again. A Rematch if you will.

Issei: Yeah I've been Training!

Vali: To Beat me?

Issei: Well... No, But I had gotten stronger!

Vali: Oh Really? Well, I can see you have Gotten Stronger, but I have been Training my Scared Gear. Do you want to go now?

Issei: No, Not now, but we'll meet soon. Star Academy, Tomorrow.

Vali: Any place, any time Hyoudou.

Frenchie: The Next Day...

Issei Had told Rias, the Occult research club, and You about the whole thing with Vali, and of course you were all there to accompany him when Vali did show up.

Rias: Vali Lucifer what do you have against My Pawn?

Vali: Nothing, I just won't take my defeat Lying down.

Rias: Issei is a Bit dumb but he's A good Person and He's A Lot stronger than you think.

Vali: I know but I'm not losing to him again, even if he's A Servant to such A Slut.

Rias: You Must-

Kiba: You're not stopping him?

Issei: Nope. It's A Win for me either way.

Kiba: I see.

Y/n: Alright Vali Pull out your Scared Gear.

Vali: Right!

He then began Unleashing A Chant as he Began to Transform and he then Transformed into his Scale Mail Armor which was Pure white instead of Red Like Issei's!

Y/n: Nice.

Vali: Now You can't stand this!

 Vali: DIVINE DIVIDING DRAGON SHOT!!

He then sent out Several Blue blasts of energy as Asia got scared.

Asia: Y/N!!

Rias: Don't worry He'll be fine.

Asia: H-Huh!?
