As everyone looked into the air, they all watched as Rias slowly descended in her pink bra, clearly embarrassed and confused as to why she was at a ruined battlefield. Taking in her surroundings, she sees that she is in Kyoto.

Rias: I-Issei? Wait, am in Kyoto!?

Y/N: (thoughts) God dammit, I'll kill Issei later. (normal) Issei, whatever you're doing, make it quick!

Listening to Y/N's words, Issei returns his attention back to Rias.

Rias: In other words, you summoned me?

Elsha: (in Issei's mind) Poke them. Poke her boobs.

Somehow Rias was able to hear Elsha and she was shocked. Her bra had fallen off as that happened.

(A/N): Kill me now. I really want to die as I was writing this section. Fucking kill me.

Issei: P=Poke them?

Elsha: Yes. Poke them. Like you always do. Boop them.

Issei: Boop!?

Y/N: Hurry it up, will you!

Issei: Shut up! No way! What's the point of poking them!?

Elsha: The nipples of Rias Gremory. They are a switch.

Issei: Wh-What are you talking about!?

Elsha: A switch to open the doors to your potential.

Issei: Elsha-sama, it's not like buchou's nipples are buttons to awaken my powers!

Y/N: Oh for the love of--yes they are god dammit! So stop fooling around and poke them!

Elsha: He is right. They are your buttons.

Rias: (starts to glow) Wh-What's going on!?

Elsha: Rias Gremory's boobs have come in contact with your potential and evolved.

Issei: B-Buchou's boobs...

Y/N: I can't believe I'm saying this...can you please poke them!? So we can finally end this battle!

Issei: This takes time! I have to cherish it!

Elsha: Do hurry up. Poking them will cause dramatic changes within you.

As he thought of this, Issei begins a huge nosebleed and Y/N and Siegfried stand off to the side. The silver haired man is confused and looks towards the black haired boy.

Siegfried: Is he always like this?

Y/N: (sigh) Unfortunately, yes.

Siegfried: I'm so sorry. I'm sorry you have to have someone like him as an ally.

Y/N: It is a shame.

Issei: (determined) I got it. I finally understand the situation. (walks to Rias) I'll do it!

Rias: (tilts head) Issei?

Issei: (perverted smile) ...Buchou, please let me poke your boobs!

Y/N: At least the explain the fucking situation first you dumbass!

Rias: (blushes madly) I-I don't really understand. I don't really understand, but I understand!

Y/N: Oh my--just kill me now. God fucking dammit...

Issei was happy and he deactivates his gauntlet, letting his finger roam free. Rias closes her eyes and braces for Issei's poke.

Y/N was trying do hard not to kill the perverted bastard already.

Issei: Are you ready, Ddraig?

Ddraig: (wails in sadness and disappointment)

(A/N): Poor Ddraig. Has to suffer through the bastard's pervertedness. Quite sad.

Issei: Sorry, partner. Here I go! (pokes Rias's breasts)

When Issei's finger made contact with her nipple, she shrieks in pleasure and she sky rockets into the air, a bright red pillar of light emitting from her.

Issei: (shocked) Buchou!?

The bright light dies down as Rias had disappeared. The others were confused.

Cao Cao: What was that just now?

Then, something inside Issei pulses. His magical power sky rockets and his strength increases immensely. His armor starts to glow as he changes into a new armor.

Issei: I'm just a pervert anyways! Let's do this! Boosted Gear! (power overflows) I can feel the power overflowing! From the bottom! From the inside! From my sacred gear! This is Ddraig's true power!

Ddraig: Yeah. It's been awhile so let me show you my full power!

Issei: I see. The Juggernaut Drive was in uncontrolled release of all this powerful energy.

Cao Cao: What is this?

Y/N: (deadpan) The power of a pervert.

Issei: It's potential! The potential future of Ddraig and I! Mode change, Welsh Blaster Bishop! How dare you hurt my friends!

On his back, Issei forms two energy cannons.

Ddraig: Boost! Boost! Boost! Boost! Boost! Boost!

Issei: This frustration! This feeling of powerlessness! I will throw all those feelings at you! Blast away, Dragon Blaster!

Two beams of energy were fired from his cannons and Heracles sees this as a challenge to endure the blast.

But, this was a poor move to do, so instead, the rest dodge out of the way and the magic attack misses, blowing away forests and causing a large explosion to occur.

Heracles: Whoa...

Siegfried: What destructive power. It even warped this dimension.

Issei: It's not over yet! (sprouts dragon wings) Cao Cao! Mode change, Welsh Sonic Boost Knight!

Flying into the air, Issei flies towards Cao Cao, enraged. Boosting through the air, he was moving at high speeds.

Issei: Not yet, Armor Purge!

Shattering his armor, he increases his speed and was moving faster than the eye could see. He charges and tackles Cao Cao, who coughs up blood from the impact.

Issei: Mode change, Welsh Draconic Rook!

His armor buffs up more, making him tougher and able to deal more damage. The change from armors damaged Cao Cao and launched him off. He twirls in the air and thrusts his lance forward and it embeds into Issei's arm, but it doesn't do any damage to him, shocking Cao Cao.

Issei throws a right hook and boosts his arms swing with a thruster, boosting his speed and power at the same time. He plunges and crashes Cao Cao into the ground, causing the blue haired man to grunt in pain. They crash and it causes a giant crater to appear in the ground, dust rising out of the impacted ground.

The dust clears as Issei falls to the ground, his power slowly decreasing. His new power had drained him.

Cao Cao rises from the crater, seemingly unscathed from the attack.

Cao Cao: It seems you were able to evolve greatly at the last moment. If I hadn't defended with the spear I would have died. However, your forms look like an Illegal Move.

Issei: Illegal Move?

Cao Cao: A term used in chess. It means an unacceptable move. Those attacks diverge greatly from the Evil Piece system.

Ddraig: I felt this was more of a Traiana.

Issei: What does that mean?

Ddraig: Triaina is the three-pronged trident used by the Greek God Poseidon. I felt the three piece transformations matched the sharpness of a trident. 

Issei: That sounds pretty good. Then, let's call it Illegal Move Triaina.

Cao Cao: However, it looks like you can no longer keep it up.

Issei: He's hard to deal with. He underestimated us before, but now he's watching carefully. So, what are we going to do? Shall we continue...?

Cao Cao: Well. I don't mind continuing...but it seems the time has come.

Soon, a bright yellow light fills the sky. They all look up to the sky and see a tear, as if a dimensional rift was opening.

Issei: Th-This is!

Cao Cao: It looks like things have started. Georg, prepare to summon Dragon Eater...No. This chi. It can't be!

Instead of Great Red coming out of the rift, it was a blue Chinese dragon instead.

Cao Cao: Mischievous Dragon, Yu-Long! 

Issei: Yu-Long?

Y/N: One of the five Dragon Kings!?

On top of the dragon's head was a man wearing a red cloak. He leaps off of it and lands next to Issei. Y/N runs up behind the two to see what was going on.

???: Oh, it's been awhile, holy spear wielder.

Cao Cao: Well, well. The Great Victorious Fighting Buddha. I never expected to see you here.

Buddha: (blows out of pipe) Ya little brat, your prank has gone too far. Some heroes rise up to become deities, while the descendants of others become the poison of abnormal businesses. As they say, a champion for only one generation. Right, Cao Cao?

Cao Cao: Poison, you say? If someone gets labeled as poison by you, I am sure they could boast quite openly.

Buddha: Hmph. (looks to Issei and Y/N) Leave the rest to me, the first-generation Sun Wukong.

Y/N and Issei: F-First-generation, Sun Wukong!?

Buddha: Red Dragon Emperor brat. You did good. So did you, Star King. It seems the legendary king has awoken.

Y/N: L-Legendary king?

Buddha: Yu-Long, take care of the nine-tail.

Yu-Long: Sure.

Yu-Long then focuses it's attention on Yasaka, who's movement was being restricted by Saji.

Yu-Long: Hey, hold on! The one fighting the fox is Vritra!

Buddha: That's right, go help him. After this, I'll fill your belly with Kyoto cuisine.

Yu-Long: That's a promise! (flies to Saji and Yasaka) Come on! Come on! Don't underestimate a Dragon King!

Buddha: (looks to Cao Cao) Well, then. Time for your punishment.

Siegfried: (draws blade) You monkey!

Buddha: Extend, staff.

Sun Wukong's staff extends and it strikes Siegfried's stomach, causing him to fly back as he grunts in pain. Flying a few feet back, he crashes into the ground and causes a large impact, a crater forming underneath him.

Buddha: You're back ins't in it. Start over with some training runs.

Soon the same purple mist forms around the Buddha, trying to put him in an alternate plane.

Buddha: Heavenly path, with a clap of thunder through the jaws of a dragon. Lay upon this land. (bangs staff on ground) 

The wind is dispelled and Georg was shocked. A howl comes from the Nine-Tails. They look over to see her struggling against both Vritra and Yu-Long.

The two dragons were quickly overwhelming her.

Buddha: Oh? Looks like things are finishing up over there, too. Things are almost over now that the nine-tail has lost her blessings.

The Buddha senses an attack incoming. Cao Cao had thrusted his spear forward as his enemy's guard was down. However, the monkey simply stopped it with his finger.

Buddha: (grins) You can't kill the other Buddhist gods with a spear I can stop with my finger.

Cao Cao: Looks like your monstrous health is still well.

Georg: Cao Cao! Let's stop here!

Cao Cao: Time to retreat, huh? (leaps to his allies) We'll stop here for now. Besides, someone else is coming.

Y/N: What do you mean!?

Cao Cao: He's not on our side. He's just someone who looks for souls. Bye for now.

Issei: Hold on a second! (forms arm cannon) Just one! I just want one attack to reach him!

Buddha: You're going to take on my duties? Well, that's fine. (taps Issei's cannon with staff)

Issei fires his energy blast and Heracles and Jeanne move to block it. However, Issei makes it turn slightly, curving it overhead and it strikes Cao Cao in the face.

Cao Cao looks up, angered.

Issei: All right!

Cao Cao: Red Dragon Emperor! Spear! Holy spear that can even pierce gods! The ideals of the king of domination that sleeps within me!

Siegfried: Cao Cao! (covers Cao Cao's mouth) It's too early to show Truth Idea! Besides, "he's" coming. Leonardo has probably reached his limit outside, as well.

Cao Cao: Red Dragon Emperor. No, Issei Hyoudou. Get stronger. Stronger than Vali. When you do that, I will show you the true power of this spear. And Y/N L/N.

Y/N: Yeah?

Cao Cao: ...The Angel of Death comes.

The teleport away and Issei breathes a sigh of relief. Y/N on the other hand was pondering Cao Cao's words. The Angel of Death?

The rest of the people then go over to the weakened Nine-Tails. Kunou then huddles over to her mother, cradling the large tail in her hands, slowly letting the tears out.

Kunou: Mother! Mother!

Buddha: (blows out of pipe) You have the power to hear the voices in woman's chest, right?

Y/N: (sigh) I forgot you even have that...

Issei: Y-Yes, I do.

Buddha: I'll help you. Can you place that spell upon the little lady and the nine-tailed princess?

Issei: I-I understand!

As Issei went to Yasaka and Kunou, Y/N was in deep thought. There was more to this title of "Star King." In fact, the Star King was known as a legendary king. He needed to ask Azazel.

Irina: Boo? Is something wrong?

Y/N: ...It's nothing.

The chestnut haired girl could hear the uncertainty in his voice. She knew something was wrong, but she didn't know what was wrong. Eventually, Yasaka reverted back to normal.

Next Day-Kyoto Train Station

Yasaka: Sir Azazel. Red Dragon Emperor. Y/N-sama.

Y/N: (sweat drops) P-Please drop the "sama."

Yasaka: As well as the members of the Gremory family. You have truly helped us greatly, I thank you. After this, I plan to meet with the Great Victorious Fighting Buddha and Lady Leviathan. I wish to cooperate with everyone so that Kyoto will never again be in the grips of terror by such people.

Azazel: (extends hand) Yeah. We look forward to it, Great Leader.

They all shake hands, an agreement of peace between them.

Serafall: I'll enjoy Kyoto with them a bit more until the meeting. Have a safe trip home, everyone.

Suguha: Bye! Onii-chan!

Y/N: (ruffles Sugu's hair) Take good care, alright?

Klein: Let me know when we're having another guy's night man! Could always use a break.

Y/N: (chuckles) Sure. I'll let you know.

Klein: Well, I got to take off for work. See you guys later.

Suguha: (gasp) That's right! I still have school! Bye!

The two go their separate ways and it was just the faction leaders and the rest of the ORC.

Kunou: Red Dragon Emperor...

Issei: You can just call me Issei.

Kunou: (blushes) Issei, w-will you come to Kyoto again? Will you too, onii-chan?

Y/N: (smiles) Sure. I'll always come visit.

Issei: (smiles) Yeah, I'll come again.

Kunou: (smiles brightly) You must! Kunou will always be waiting for you!

Issei: Yeah!

Kunou sees them off and the bullet train departs for the small town of Kuoh. Yasaka puts her hands on her daughters shoulders, smiling.

However, Yasaka's face turns grim as she looks to Serafall.

Yasaka: Does he know yet?

Serafall: ...Not yet. I want him to live his life more. He's not ready for what's to come.

Yasaka: In time he will. Now that the Star King has awakened...so has the Angel of Death and Administrator.

Timeskip-Night, Hyoudou Manor

Rias: Why didn't you let me know?

Issei: Y-Yes.

Akeno: You told us you would contact us again after Kinkakuji. And then, nothing.

Koneko: Yes, you were very distant.

Gasper: B-But everyone managed to come home safely...

Azazel: Well, Issei met a mew woman there, too. And the daughter of a nine-tailed fox, no less.

Y/N: He even managed to win her heart.

Issei: Th-That's not true! Don't say things in such an ambiguous way!

Azazel: (smirks) But, looking at Yasaka, I bet that girl will grow up as quite a well-endowed beauty.

Issei: Th-That may be true! But I don't have any interest in little girls! Gyah!

Koneko had punched Issei in the stomach. He clearly struck a nerve.

Y/N: Struck a nerve there didn't ya, Issei?

Kiba: That he did.

Issei: Why?

Koneko: (annoyed) No reason.

Azazel: Well, Rias. Issei really powered up in Kyoto, why not forgive him?

Rias: Well, I am happy about that. He summoned me and then, breasts... (covers chest)

Issei: Buchou! I'm really sorry about that! And, thank you very much!

Y/N: Die.

Rossweisse: (sigh) Anyways, we managed to follow up on the molester issue, too.

Y/N: Issei's fault!~

Rossweisse: With this, the school trip will end safely... (covers mouth as she is about to puke)

Azazel: Now we have the school festival to look forward to. By the way, the daughter of the Phenex family will transfer into Kuoh Academy around that time.

Y/N: (sigh) More rivals?

Kiba: Yep. More rivals.

Issei: Ravel will? Seriously!? And what do you mean "more rivals!?"

Kiba and Y/N: I can't believe that your that dense.

Azazel: Yeah, she was greatly impressed by Rias and Sitri and wished to study in Japan. She will be a first year like Koneko.

Koneko: (pouts) I don't care.

Y/N: (whispers to Kiba) Yikes. Remind Ravel to never piss off the Rook.

Kiba: (whispers) Duly noted. Think it will be more hectic?

Y/N: Of course there will be.

Issei: That's a sudden transfer. I wonder why?

Azazel: Things are tough for all of you.

Rias: Well, it's fine. I guess it is enough that you all have returned safely. And we have the Rating Game with Sairaorg to worry about. We need to focus on our preparations for it.

Y/N: Wish I could compete.

As everyone was getting ready for bed, Y/N stops them.

Y/N: But before that, Azazel...

Azazel: Judging for your tone of voice...

Y/N: Who am I? What is the Star King? Tell me.

Somewhere Else

In a large tower on the top floor was a bed. Sitting on it was a light purple haired woman and standing next to the bed was a blonde haired man.

???: It seems the Star King has awakened.

???2: It seems the War for Underworld begins once again. Have we found Cardinal?

???: Not yet. But soon. The Star King must be stopped at all costs.

???2: PoH failed to stop him before. Should we send Chudelkin? We can't use our Integrity Knights.

???: That's right. They are still loyal to the Star King himself. How about we send Shasta, Vecta?

Vecta: Why of course, Administrator-san. Or, Quinella.

Quinella: Come take your kingdom back, Star King.

------------------

So originally there was going to be a big fight scene involving Y/N, but I had a better idea and I was going to postpone it later. Somewhere along the lines, we'll have a bit more of Alicization styles sprinkled in here. Anyway, hope you all enjoyed the chapter. Thanks for reading it. Half way done with season 4 still. I'm not sure whether to involve the reader in the Rating Game against Sairaorg since the reader is not apart of Rias's peerage. I don't know. I'll figure it out. Anyway, stay safe out there.
