Welcome to Chapter 31: Dragon Force. In this chapter, Natsu faces off against the real powerhouses of the Gremory and Sitri group. Having watched the other battles, the girls are unsure of how to proceed. Let's see what happens.

Natsu sits in his Flare Drive mode waiting for the beginning of the battle. "So guys, are you ready to go?" Natsu says smiling darkly. "After watching the first battle, surely you have some idea of what to do."

"We're ready for you, Natsu. Don't worry; we won't go down as easily as the others did." Rias says happily as everyone gets into the battle modes. Rias powers up ready to go; Saji activates his Vitra Promotion; Akeno gets into her battle uniform; Kiba activates his balance breaker and switches it to Excalibur; Tsubaki gets Mirror Alice ready to go and Sona powers up but surprisingly doesn't use her uniform.

Looking at Sona, Rias is shocked to find she isn't using her power "Sona, what are you doing? Why aren't you using MMPH!" She's quickly stopped by Tsubaki.

"Sorry, Rias we don't know if Draconis is watching. Remember, he authorized this, so surely he is watching to make sure." `

Natsu intervenes, amused at the girls words "IF you think that bastard Draconis is watching, your wrong. He's more concerned about his pupils fighting Joey. Although, if my guess is right, that battle was over a while ago and they're off to do a separate training."

"What do you mean, Natsu?" Sona asks quizzically.

"Simple, the fact is you guys were never going to get all four paths in the two weeks you had. I mean really, let's say you somehow manage to beat me, which you won't. You have three dragons more powerful than me waiting for you. If you had two months, you might have a chance. Another thing to remember is if you lose this round, your challenge ends and there's no guarantee I'd fight you in your return."

The group is shocked realizing what's about to happen. "My God so this truly is the path of Kings. How did Issei and Vali beat it?" Tsubaki says shocked at the revelation.

"Yeah, the truth is five years ago I fought Draconis and lost. It took him almost five hours to beat me, and with him I actually had to use my full power at the time. As for the other dragons he fought, I don't know." Natsu says smiling. "Anyway, if you're gonna beat me you gotta go all out, and then some."

Giving in Sona transforms into the blue outfit Serafall gave her. Sona is shocked at the power coursing through her. "No way! I thought this was a joke from my sister."

"The first move is yours Natsu." Rias shouts as everybody stands ready.

"Gladly Rias, but you'll regret that pretty quickly." Natsu says as he vanishes with high speed.

The whole gang stays put afraid of what will happen, but Sona thinks back to the last battle and quickly figures out what he's going to do.

"Kiba! Get ready; he's going to go after you. Last time he attacked the bishops because they were long ranged. Most of us are long ranged, so he'll attack you first to get you out of the way." Sona screams as Tsubaki gets focused.

"Nice guess." Natsu shouts appearing behind Kiba. He quickly punches Kiba knocking him to the floor but keeping him conscious. What most of the group didn't realize is a magic circle also appeared on Kiba.

"KIBAAAA!" Tsubaki shouts. Appearing behind the young woman he quickly taps Tsubaki activating another magic circle. As Rias and Sona quickly try to analyze what's happened, Natsu appears in front of them smiling as though nothing has happened.

"Well this is a letdown. I was hoping for a much better fight." Natsu says as he powers up a massive dragon shot intended for Tsubaki.

"Gotcha, now take this!" Saji shouts charging at Natsu from the side with high speed. Saji goes for a roundhouse kick which Natsu easily dodges.

"Really. I would've thought Vritra taught you better." Natsu says as he switches targets to Saji blasting him with the dragon shot.

"SAJIII!" Sona shouts. "Take this! Water Dragon!"

"I got your back Sona! HOLY LIGHTNING!" Akeno shouts as she fires a combined lightning strike at the group.

Natsu smiles viciously at the latest attacks. Looking up at Akeno and Sona he smiles and yells "Big mistake!" Just as the attacks were about to hit, Natsu snaps his fingers.

"We got him!" Akeno shouts, sure that the combined attacks have done their job.

"No you didn't." Natsu whispers behind Akeno. Quickly casting his magic, a pillar of fire engulfs Akeno, making her scream out loud in pain.

As the dust clears from the previous attacks, the gang is shocked to find Kiba and Tsubaki lying down and Akeno is panting heavily, surviving the brutal attack.

"But… how did… I miss?" Akeno says panting out loud.

Natsu back in front of the group unharmed explains what happened. "Well you didn't miss I just redirected your target. You see when I hit that girl and your knight earlier I used a magic spell that let me switch their positions." Natsu says noticing Saji coming out of the corner of his eye. "Hold on a minute. Let me deal with Vritra here." Natsu quickly turns towards Saji's and gives him a flaming roundhouse kick right to the stomach, this time knocking Saji out.

As Saji falls from the attack, the gang is shocked. The battle has gone on for five minutes and Tsubaki, Kiba, and Saji are all gone.

Looking at Akeno and Rias and their dejected faces, Sona does the unthinkable. "Natsu we surrender."

Akeno and Rias seemingly agree and the group powers down. "That's right, we lose. Unfortunately we can't win against you, Natsu. That's clear now." Akeno says regrettably.

"So why did you guys so easily give up? It was the right choice, but why?" Natsu says smiling.

Sona speaks for the group. "Rias and I are powerful, but our attacks are predictable, and you could target either of us easily with that speed. You used a lot of feints in this battle and we would get picked apart."

The group makes their way to the entrance of the path. Once they arrive a surprising person is waiting for them. "You made the right decision ladies. From where I was watching, you guys didn't stand a chance." Azazel says smiling.

Rias and group are shocked to find Azazel sitting there waiting for the group. "What are you doing here Azazel?" Rias asks clearly annoyed.

"I came because I realized that if you guys wanted to get where you need to be, I needed to change things." Azazel says smiling. "I'm changing things up from here on out and I got Tannin's approval. Instead of training you guys by having you fight, I'm gonna have you guys train with the dragons to boost your strengths and master your sacred gears."

"Azazel, but wait, you're a member of the order of Draconis. Why are you helping us fight against Issei?" Rias asks curious.

"Easy. It's because I was assigned to be your advisor. As a result, I have to help you guys as much as possible." Azazel says smiling.

"Thank you Azazel" Sona says smiling finally trusting the fallen angel leader.

Back at the Order of Draconis base Issei is seen sweating after a training session.

"Thanks for the battle, Issei. It's been a while since we've fought. Even though you werent at full power; it was nice to fight my rival for once." Vali says smiling.

"Of course, Vali. Irina was right. I do need to train once in a while. Even like this. I had to keep monitoring the girls. Regardless, if I actually need to fight against Rias and her gang, I'll be heavily disappointed." Issei says laughing.

"Don't worry, everything will be fine." Vali says with a rare grin. "Did you know Azazel is sending Rias and group to train with Tannin?" Vali asks curiously.

"I know that Vali, who do you think suggested Tannin? If I left them alone, they'd be easily crushed by us, and preparing them for the Khaos Brigade is the whole purpose of this mock battle." Issei says smugly. "Anyway, I've got to get going." Issei smiles making his way back to his room.

When Issei arrives in his room, he senses two very familiar people waiting for him.

"Well Partner, it seems as though you're getting a rare treat." Ddraig says with slight joy in his voice.

"You're right, Ddraig. I wonder what they're up to?" Issei says smirking. As he opens his door he's met with a rare surprise. Irina and Xenovia are sitting by his bed; both naked and, from the looks of it, ready to go. Issei gets a quick whiff and notices the room is filled with female juices.

"So Irina, you always said Xenovia could never have me. Care to explain why she's naked in my bed along with you?" Issei says smiling.

"Uhh...well...you see, Xenovia and I were playing cards, and we decided to make things interesting. I told Xenovia that if she beat me she'd be allowed to have sex with you and well... I lost. " Irina says sheepishly.

"That doesn't explain why it smells like you two had sex on my bed." Issei says with a cruel grin

Irina blushes heavily. "Well here's the thing. We were waiting for the last ten minutes and we got bored, so Xenovia and I decided to play with each other while waiting for you." Irina says sheepishly.

With a facepalm, Issei looks to the girls with a grin. "Oh well that suits me just fine." Issei starts to undress making his way towards the panting girls.

LEMON START:

"Xenovia, Irina, why don't you girls get my little dragon ready to go using those lovely breasts of yours." Issei smiles as he lies down on the bed. Following his commands, Xenovia and Irina give Issei a double job using their tongues to multiply the pleasure. "MHMM! Xenovia, Irina, you girls are incredible." Issei moans as the double titjob gets him harder than he has been in a while. Xenovia and Irina slide their breasts up Issei's massive junk and finally after five minutes, Issei reaches his climax.

"AHH! Irina, Xenovia! Here I go!" Issei moans as he splashes both girls with his cum.

"Ahh! So hot Issei, I can't wait until you're inside me." Xenovia says with a grin, although her face is filled with cum.

"Very well Xenovia, I hope you're ready." Issei says smiling as Xenovia gets into Issei's favorite doggystyle position. "How did you know I like this position, Xenovia?"

"Irina told me. Now hurry up, I want to have sex with you already." Xenovia says clearly impatient.

"Very well Xenovia. Irina this round is all Xenovia, so sit there and wait." Issei says as he impales Xenovia with his cock. "Hmm, so you aren't a virgin?" Issei asks curiously.

"No, I am. I broke my hymen during training. Now get to thrusting already." Xenovia says as Issei quickly resumes his work. For the next ten minutes, Issei thrusts into Xenovia's tight pussy. During that time Xenovia cums two more times. Irina is stuck masturbating during the ordeal, but she came twice as well.

"Xenovia! I'm cumming! AHHH!" Issei shouts as he blasts a load into Xenovia. Quickly recovering he motions to Irina, who from the looks of it is exhausted. "Irina, come over here and get on top of Xenovia." Issei motions as he summons over Irina.

Irina makes her way over towards her partner and Irina lies on top of Xenovia both of their pussy's facing a thrilled Issei.

"Now let's go, Irina, Xenovia." Issei smiles as he begins to work on both girls together. For ten more minutes, Issei thrust in between Xenovia and Irina, making sure to pleasure each of them. Issei even makes sure to get both girls in the ass to ensure maximum pleasure.

"Here we go girls! I'm cumming!" Issei says to the two girls, who each seem to be exhausted.

"Issei I'm cumming!" Irina moans loudly.

"Me too, Issei!" Xenovia moans just as loud.

As the screams fill the room, Issei blasts into Irina and pulls out just in time to fill Xenovia with a little bit of cum.

LEMON END

As the two girls lay exhausted, Issei simply laughs. "Well, Ddraig, that was fun."

"Yep partner, I wondered when you'd finally get the blue haired girl. Well, since they're lying on your bed, I guess you can use the playroom to take a nap." Ddraig says calmly. "Its gonna be a long day for you buddy.."

As he walks towards the playroom, his thoughts go to Rias and his old teammates. "Well Rias, I hope your taking your training seriously because we're gonna go all out."

That's it for Chapter 31. So Rias and gang stop their training with Natsu and Issei has his fun waiting for the battle to begin.
