Chapter 6


"So we're going to help Rias train?" Issei asked as she looked at Sona doing a so-so motion with her left hand.

"Not exactly. Rias wishes to test her peerage's abilities since the Rating Game is tomorrow, and I do have a sneaking suspicion that she'll want to see how strong you've become in hopes of you assisting her team." Sona explained before sighing into her girlfriend's shoulder, which made Issei smile at her King as she wrapped a wing around her, making Sona moan in comfort as she loved the warmth the wing provided her.

"Are you sure you're not mad that I asked to come with you? I know Tsubaki-senpai usually goes with you since she is your Queen, but given that she came down with Devil Flu, I wanted to be sure if you were okay with me being your bodyguard replacement." Issei said as she felt flattered that Sona had come by in the morning and informed Issei that the Sitri Queen had fallen ill and couldn't come to the Underworld, so Sona asked Issei to go as her bodyguard.

"Of course not. Tsubaki recommended you and believed you would be an excellent candidate for my third in command should anything happen to me and Tsubaki." Sona explained as Issei was surprised by this revelation before hugging Sona in her arms while holding in her squeal, which made Sona chuckle at her lover's reaction.

"Thank you, Sitri-sama."

"We're alone. You can call me Sona."

"Okay then," Issei said as she kissed Sona's left cheek and lips, making the heiress stiffen from the gentle and chaste kiss before Issei giggled at her girlfriend's reaction.

"Aw. Is someone a bit flustered?" Issei asked with a teasing grin while Sona looked away, not wanting to get caught in the trap.

"Y-You!" Sona stuttered as she wanted to yell at Issei but couldn't help but look at the Fallen's lips before shoving her face into Issei's chest and yelling at them.

Issei giggled at the feeling until looking down at Sona's eyes as her cheeks were puffed like a chipmunk.

"Your such a tease, you damn seductive Crimson Empress."

"Oh, I'm flattered, my King. Should I call you So-Chan then if we're using pet names?" Issei asked as Sona blushed and looked away. She was nervous about it coming from her girlfriend's lips before muttering.

"O-Only when we're alone," Sona said as Issei heard it and smiled at the Sitri Heiress before picking up her left hand and kissing it.

"As you wish, my King," Issei said as Sona couldn't help but imagine her Fallen girlfriend in a knight's armor, with that same smile, holding out a hand for her as if she came to take her hand in marriage.

'Dammit! I've got to stop reading so many medieval romance novels. Why would Tsubaki even recommend those books to me?!' Sona asked herself mentally while enjoying the comfort of her lover's warmth.

Issei smiled as she looked at her King's reaction and mentally took a picture before looking at her left arm and seeing the bracelet Azazel gave her a few days ago. The bracelet may look normal to others, but it helps Issei control her emotions so she doesn't give in to her rage and fears.

[Still worried about giving in to the temptation?] Ddraig asked as he was surprised by his partner's decision concerning Issei's body and the bracelet's effects.

'Yeah. I can tell the bracelet is working, but a small part of me can tell it can't hold my rage back forever.' Issei said as she clenched her left hand and could see it slowly forming into more of a dragon's claw than a human hand. Issei calmed her breathing as she watched her hand stop mid-transformation before it slowly turned back to normal, which made the Fallen sigh in relief.

"You okay, Issei?" Sona asked as she looked at Issei for a moment until Issei kissed Sona's lips, making the Sitri Heiress blush at the kiss before Issei reassured Sona by rubbing her head while Sona hid her face in her girlfriend's bust.

"Of course, my love. I'm sorry for worrying you. I was thinking." Issei said with a smile as the train began to slow down. Sona was sad it was back to business, but Issei reassured her they could cuddle on the way home.

The two then left the train. Issei thanked the conductor and the others for the safe passage before she continued walking next to her King.

"So, how shall we proceed with Gremory-Senpai's request? Take them by surprise, test their abilities, or crush them with our power?" Issei asked as she was excited about the battles until Sona grinned at Issei before pulling her left ear.

"Ow! Ow! Ow! Come on, Sona! Can't you take a joke?!" Issei begged as she could feel her left ear almost come off until Sona let the victim as the Sitri Heiress spoke to her girlfriend.

"We're here to spar with them. You may use whatever skills or weapons you desire but do not go too far." Sona said as the two continued to walk towards the mansion to see that Saji was getting his ass handed to him by a gut punch Koneko herself, making Issei wince in pain as she could feel the pain that Saji was going through.

"Ouch. I feel sorry for the poor guy." Issei said as Sona then walked towards the mansion and announced her presence, as well as Issei hurried over to her King before smiling at Rias, who appeared to be happy that her friend had come to the mansion.

"I apologize for coming unannounced when you only have a day left to train, but Rias asked me to come and see how strong you've all improved during the past two weeks. That is why I brought Issei with me to test your skills." Sona said as she gestured to Issei, who smiled as she waved at them before taking off her cloak and revealing her fighting attire.

Juri from Street Fighter inspired the attire, so Issei took upon some of the apparel from the warrior. Issei was now wearing a purple dudou (a form of Chinese bra-like top) on her chest, supported with eight straps that meet on her back, forming a spider pattern. She wore long, baggy, off-white sweatpants, purple tights, and long, fingerless gloves. Her fingernails and toenails were painted dark black. Her dark hair was styled into a ponytail with two little 'horns' on top of her head, which appeared fastened with purple ribbons. Issei also wore Taekwondo foot wraps on her feet as she smiled at the reactions of the Gremory Group.

Kiba and Koneko blushed at the Fallen's attire as Akeno licked her lips at the body before her while Saji held back a bloody nose from seeing the outfit and how much skin it showed.

"Yep. So who's first?" Issei asked as she cracked her neck and knuckles while letting some of her dragon's aura out as her eyes shined brightly. The inner dragon of the Fallen wanted to go all out and destroy them. Still, Issei held back her newfound battle lust as she had enjoyed fighting and taking down her opponents, which damaged the school courtesy of Ruruko, Issei, and Tsubasa.

Sona walked towards Rias before the two heiresses left the battle as Saji readied himself to go first.

"So. How has Saji improved the past two weeks?" Sona asked as she watched Issei go into battle with a dangerous glint in her eyes as she began to use many kicks to keep Saji at bay from using his Sacred Gear or Promotion before Rias replied to her.

"Saji has been improving well, although I am a bit concerned about him since I'm worried he'll be taken out quickly given his limited fighting skills and how his Sacred Gear can help us deal with Yubelluna should he surprise her," Rias explained as Issei continued to pummel Saji with multiple kicks before jabbing him in the stomach with her punches until Saji was able to use his Promotion to use the Knight's speed to get away.

However, it was in vain as Issei was right on top of him, without using the Promotion, and hit Saji with a left hook that sent him flying until he was unconscious on the ground.

"Hell Yeah! That's how it's done!" Issei cheered as she winked while doing a two-finger salute to her audience. Rias was surprised by Issei's power until Sona explained it to her.

"Issei has been training in combining the power of her Fallen form and her new abilities from the dragon. Thanks to her training with my peerage, she's becoming stronger and more like a dragon. However, Issei tries to control her battle lust and rage as she gives into her dragon form." Sona explained as Issei took a few deep breaths and relaxed her body before opening her eyes to show that they were back to normal.

Koneko was surprised by this since she had been training in secret to control her Senjutsu form but couldn't properly control the power within that form, however seeing Issei, someone who's got a lot more control over their abilities, made the Rook clench her left fist as she wanted to be on that level of power as well.

Kiba went next, and luckily, he held on longer thanks to his speed, but his weapons didn't mean anything as Issei used light weapons to clash with his devil weapons before using her strength to get Kiba on his knees and defeat him.

Akeno excluded herself from the battle to tend to Kiba and Saji and also for other reasons that were not mentioned. Still, Rias could tell that it was also due to Akeno knowing that Issei could quickly destroy her in a battle, leaving only Koneko as She tightened her training gloves while stretching her body and eyeing Issei's form.

'She's gotten stronger, and her fighting style combines strength and speed. If I get too close, she'll easily blast me away with her incredible power, but I can't get away due to her speed. I'll have to rely on that power to give me the edge, and hopefully, I don't lose control.' Koneko said as she got down on all fours, which surprised Issei, as she was interested in this change in Koneko's eyes until the Rook shot towards Issei and began to try to deliver a punch to the Fallen. Still, Issei deflected all attacks with ease while looking a bit bored.

Koneko then tried to switch to kicks, but Issei merely blocked them as she could predict her opponent's moves and could feel that they were weak but also sense a strange power in the Rooks body.

Issei then decided to draw out that power by catching the kick from Koneko before throwing her into the air. Issei then used her legs to leap into the air, delivered a devastating high axe kick, and dropped Koneko back toward the ground. Still, Issei teleported to the base and eyed Koneko's falling form before she readied her left hand as the Rook descended.

"Nap time Kitty!" Issei shouted as she punched Koneko in the chest, making Koneko spit out some bile before being sent flying into the forest, which made Issei sigh in disappointment.

"Such a shame too. I can tell Koneko is stronger than she lets on but holds back for some reason." Issei said as she was about to walk away while Rias wanted to interfere and get Koneko, but Sona held her back.

"Let me go Sona! Koneko is-!"

"She's fine. I can sense her aura, and she's healing right now. I understand why you want to stop it, but let it continue. This might be what Koneko needs to control it." Sona said as she knew about the Rooks' past thanks to Rias and could tell that if anyone could help Koneko control her power, it would be Issei Hyoudou.

Rias wanted to disagree with her until she sensed a massive burst of energy from the forest as Koneko slowly walked out of the trees with a light blue aura while cat ears appeared on top of her head, and two tails emerged from her skirt.

Issei was surprised by this and granted a part of her wanted to squeal at the sight of the cute Catgirl before her; the dragon within her wanted to test out this new power, so Issei let a toothy smirk appear as she licked her lips in glee.

"Well, well. This is going to be fun." Issei said as she readied herself Koneko blitzed over to Issei and punched her in the stomach, which sent the Fallen Dragon back a bit, but the Empress looked at her stomach and saw the bruise heal up quickly.

Issei wasn't bothered by this, so she still had a challenging grin as she looked at Koneko and laughed excitedly.

"Yes! This is what a real battle should be! Going all out and holding nothing back to crush the enemy to dust!" Issei's said as she let her wings out and released her aura, which made Rias sweat at the sheer amount of power within her.

"T-This power. It's similar to a High-Class Devil. What kind of training did Issei undergo in the past two weeks?" Rias asked herself while Sona was tempted to stop her Pawn, but Koneko's aura rose to match Issei's, making the small Rook smile in joy as she began to ready herself to attack while the ground caved beneath her feet.

"Koneko Toujou!" Issei yelled as she summoned the Boosted Gear and smiled with her eyes glowing. "Let's go all out and hold nothing back! Anything less is boring! Let's fight as true beasts and warriors!"

Koneko's eyes matched Issei's as they were more of a beast than a human before the two dashed towards each other, destroying the ground beneath their original spots before they met in the center, exchanging blows that did damage them but both of them didn't care as they were enjoying the battle.

Koneko used her punches and Ki to enhance her physical strength, which sent Issei back a bit, who only smiled even more as she charged through the Ki blasts and delivered swift but decisive blows to the small Rook while laughing in joy.

Koneko straightened herself in the air as she sent more Ki blasts at Issei, who began to run while dodging the attacks before she leaped into the air and summoned a massive ball of energy in her left hand.

"Dragon Shot!" Issei shouted as she punched Koneko with the force of a mountain, sending the Rook into the ground until she got up as her wounds healed thanks to her Senjutsu.

Koneko looked at Issei, landing on her feet before her until the Rook smiled at her.

"Thank you Issei-senpai. I knew I could count on you to help me control this power." Koneko said as she got on her feet again and punched her fists together. Her aura exploded even more significantly, making Issei smile as she hit her fists together.

[BOOST! BOOST! BOOST!] Ddraig's voice roared as Issei felt more power enter her body, not noticing how her body was changing to that of a dragon. Her eyes became slit while her claws and fangs appeared as well. Her skin began to develop crimson scales as her tail, and the massive dragon wings on her back began to appear.

Issei and Koneko looked excited until they charged at each other, with Issei's aura covering her body, making her look like a true dragon was charging in. In contrast, Koneko's aura made her look like a Youkai was charging in. As they met in the center, the two delivered one last punch, creating a massive wave of energy that pushed everyone off their feet.

Rias and Sona coughed as the smoke lifted from the field. At the same time, Akeno panted heavily from the barrier she used to protect Kiba and Saji, as well as herself, from the explosion until the spectators looked to see Issei and Koneko back to normal as Issei walked towards Koneko and ruffled the girl's head. In contrast, Koneko looked up at her senpai's eyes with gratefulness.

"That was a fun match Koneko. Let's do it again after you kick ass." Issei said with a toothy grin while Koneko smiled at the idea of fighting her senpai again before nodding.

"I'd like that, but I want something more," Koneko said as she wrapped her hands around Issei's neck and kissed her lips, which surprised Issei as her dragon instincts told her to kiss back with their tails entwining each other.

Sona was surprised at this but didn't interrupt them due to her mind telling her that the two combatants were following their primal instincts instead of being rational, so she didn't interfere until she saw Issei end the kiss and carry the Rook in her arms bridal style back to Rias Gremory before bowing to her King.

Koneko is more than capable of taking down Riza's peerage. Issei said as her tail swished in the air. Sona sighed while rubbing her forehead before nodding.

"Indeed, but I think it was thanks to you that Koneko was able to go all out," Sona said as Rias took Koneko to the mansion before Sona pulled Issei into a kiss which shocked both Rias and Akeno since they never saw Sona be so forward, especially when their tongues began to wrestle with each other.

Akeno's eyes were glazed at this as she imagined herself kissing Issei and being dominated by the dragon.

"Mmmm...I want to join in this session." Akeno said as she rubbed her legs together while Rias blushed at the kiss before Issei and Sona separated with a trail of saliva connecting them.

'W-What was that?! That looked like something in a porn film!' Rias yelled as she felt turned on and left out as she wanted to experience a kiss before Sona turned around and looked at Rias with a regular expression as if she wasn't just making out with her Pawn.

"N-Now that we're finished here, we'll be taking o-our l-leave!" Sona moaned as she tried to control her horny girlfriend, who was nibbling on Sona's neck and licking her sensitive areas, which Sona didn't even know.

Rias just nodded as Sona teleported them out of the Gremory's territory before Rias took Koneko into the mansion and began to heal her. At the same time, Akeno brought Kiba and Saji back inside before she began to finger herself in her room.

"Feeling that power and aura from Issei made me want to submit myself to her. Fufufufu.~" Akeno said as she began to massage her chest before pinching her nipples, making her moan erotically. At the same time, Rias tried to plug her ears from Akeno's session but was turned on by Issei's aura before heading to her room.

"Screw it," Rias said as she took her clothes off and headed to the showers in hopes of cooling her body down and forgetting about the sexy dragon empress that was able to obliterate her peerage.

"Dammit. Why is it that my heart wants me to be with Issei?" Rias asked herself as she felt the cold water cool her body down.

Sona felt on cloud nine, overwhelmed by her over-affectionate girlfriend, who acted more like a beast who wanted to mate with her. Still, a blast of cold water could cool Issei's mind and body down before Sona took her to the hot springs she had in her home to warm up her lover.

"Damn. You turn into an affectionate dragon after all that power, huh?" Sona said as Issei hissed while nuzzling into Sona's neck before the heiress calmed down her Pawn.

"Easy, Issei. Just calm down and let the water take it away." Sona said as she used the hot springs to warm her lover and calm Issei's mind. Sona then looked at the bracelet on Issei's left hand and could tell that it kept her power in check while ensuring she didn't let loose too much power.

"It's no surprise that the power Issei radiated was her aura before Ddraig gave her those three power-ups. She's come a long way during the past two weeks." Sona said as she knew that Issei trained day and night to control her power so she could test her limits.

"I can tell she's unlocked the Boosted Gear's Balance Breaker, but why hasn't she released it?" Sona asked Issei, who only moaned in reply until Sona could tell that the dragon had fully recovered from her battle with Koneko Sona then took Issei out of the hot spring and dressed her up in some silk pajamas, which made her look even sexier than before.

"Dammit. Curse you, Serafall, and your tits." Sona whispered to herself as she couldn't help but ogle Issei's breasts before snuggling up to the dragon but could tell that Issei was still semi-conscious as her arms wrapped around Sona's waist and brought the heiress closer to her body, which made Sona blush as her head was in her Pawns chest and could smell the dragon's scent so well.

'She smells like grapes and fresh flowers while her body reminds me of a warm summer breeze.' Sona muttered as she could hear Issei's heartbeat and slowly fell asleep.

'Damn. I'm falling for this girl.' Sona said as she fell asleep in her girlfriend's arms but didn't notice a third person teleport into the room and smile at the two before taking a photo of their position.

"Mom and Dad are so going to love this," Serafall said as she waved her wand and left the room, while Sona merely mumbled while snuggling into her Pawn's arms.

Serafall giggled as she looked at the photo of Issei and Sona together in bed before putting inside a scrapbook of pictures of Sona and Issei together at different times.

"I'm so proud of Sona for finding someone she loves with all her heart," Serafall said as she looked at her little sister's photos from before and sighed as she touched them with a sad smile.

"I'm happy for So-Chan, so why does it feel like I will be alone when Issei does best Sona in chess? Will my baby sister still want to play with me?" Serafall asked herself as she felt jealous of Issei since she could tell that the Red Dragon Empress made her sister happy. An older sister always looks out for the younger one, so why would Serafall want to separate them when Sona feels so pleased with her beloved Pawn?

"Heh. I guess I do deserve the title of Leviathan. I am an envious devil who only wants my sister's love for myself." Serafall said as she knew that her obsession with her sister also made the Leviathan want to keep that love for herself. However, deep down, Serafall knew that if she went too far with her advances in wishing to marry her sister, she would push Sona away even more.

Serafall cried to sleep as she couldn't imagine her future without her sister still wanting to be with her and calling her Onee-Chan when they were younger.

"Please So-Chan. D-Don't leave me alone. Don't leave me." Serafall cried as she let her aura out. It began to freeze the air around her.

"Hm. It seems Ddriag's partner has already awakened the Boosted Gear. This'll be interesting, huh, Albion?" A tall silver-haired woman said as she looked at the sky while feeling a particular dragon's aura that made her body shiver with excitement.

[Indeed. Ddraig's partner has unlocked the Balance Breaker but hasn't yet revealed it. Perhaps she can't control it yet?] Albion suggested as the woman shrugged her shoulders.

"Who gives a shit if she can't control it or not? The best way to learn is by using it. I think it's time I cash in that favor Azazel owes me." The woman said as she walked back to the Grigori and smiled at the idea of clashing with her rival.

"Oh, I'm going to enjoy meeting my rival. I wonder how I should challenge her. Threaten her family and friends? Not too cliche. Challenging her is tempting, but I like to take her off guard to test her reaction speed." The woman said as she continued her walk while pondering how to meet with the Red Dragon.

All in all, things are about to get interesting...


Scene.

Now don't worry about Vali. The White Dragon Emperor is still here, but it'll be more fun seeing Vali ponder how to approach Issei and challenge her to a duel to see who's stronger.

Vali will have more screen time after the Ratings Game, and Serafall will play an exciting role in the next arc since I wondered about her obsession with Sona and recalled that her sin is similar to Envy since she envies those who are close to Sona and fears of losing her beloved sister to someone else. That's why I wanted to show Serafall's mental state, as she wants Sona to still be there with her but is afraid of losing her to anyone interested in her.

Now Issei's decision will be revealed after the Ratings Game. Still, as for those who are pondering the battle between Koneko and Issei, I wanted to show that Koneko's power level is weaker than Kuroka, who has more experience in using Senjustu, but when Koneko loses control of herself, her full strength is released. I estimated that if Koneko used her full power, she would be Low Tiered High Class. She was not on par with Riza, but she would be able to deal some deadly damage to her foes.

Now for those pondering on Issei's transformation and her power level. It's due to Issei being not just a Fallen that has more power thanks to her training with the Sitri Peerage but also to her unlocking more power from the Boosted Gear. Granted, she has sacrificed a part of her body to the dragon to help her get stronger quickly, but that'll be revealed when Issei clashes with more vital forces.

For now, her power level is around High Tiered High Class. Issei isn't all-powerful but can fight against those like Kokabiel and Vali.

I hope you all enjoy it, and I will see you all next time!
