Issei started to run towards Shalba and created a magic circle on his hand and send a barrage of attack at Issei but he dodge or parry some of them with his Blades of Chaos. Issei throw his left blade at Shalba but he dodge it. He grab the blade's chain and spin it around and throwing Issei out of the castle.

Issei: "Guess you weren't all talk like that bastard Astaroth huh?"

Shalba: "Of coarse not. Unlike him, I have my own power of being the old Devil King Beelzebub mix with the power of Orphis who is the Dragon God."

Issei: "I guess you could do to provide some entertainment for me. Come on then."

Shalba: "Don't take me to lightly Boy!"

He rush towards Issei while preparing a magic circle on his hand. But Issei used the Flames of Ares and charged it to the blades and impaled the ground when Shalba was near him.

The explosion cause Shalba to fly away and destroyed the remaining castle.

Shalba: "UGH! Bastard!"

He stand up again, gathering his magic in his palm and throwing it to Issei. The attack destroyed everything in it's path and it hit Issei in the chest it cause a huge explosion.

When the smoke clears, Issei was still standing but his Balance Breaker is destroyed as well as his shirt and he has some bruise on his chest.

Shalba: "Hahaha! I told you that you will pay for mocking me, boy!"

Issei: "Hehe, guess this is what they called 'Lucky Shot' huh? Hey Ddraig."

Ddraig: "Yes Issei?"

Issei: "We'll be doing that move."

Ddraig(Shock): "A-Are you sure Issei? That will leave a stress on your body."

Issei: "Let's just test drive it."

Ddraig: "Very well Issei."

Issei / Ddraig: "I, who am about to awaken,
Am the Heavenly Dragon who has stolen the principles of domination from God
I laugh at the 'infinite', and I grieve at the 'dream'
I shall become the Red Dragon of Domination And
I shall sink you to the depths of the crimson purgatory!
JUGGERNAUT DRIVE!"

Issei's Balance Breaker slowly turning into a giant Humanoid Dragon with a skeletal wings. Shalba couldn't do anything but to watch Issei transform in horror. A few seconds later, Issei finished transforming while still holding the Blades of Chaos which grow to his size too.

Issei: "Let's continue, shall we?"

Shalba(Shock): "That's not possible! The Juggernaut Drive weren't suppose to be controlled easily!"

Issei: " Guess I'm an exception."

Issei rushed towards Shalba and kick him away,. Shalba spread his wings and fly back towards Issei while shooting him with his magic.

Shalba: "I WILL NO BE DEFEATED BY YOU, RED DRAGON EMPEROR!"

He did the same attack before but the attack was a little bigger. He throw it towards Issei's chest and it hit him directly.

Shalba: "HAHAHAHA! Even if you are in Juggernaut Drive, You cannot survive a Devil King's attack!"

When the smoke clears, Issei was just standing there like nothing happen. Shalba's eyes went wide to see Issei still well even thought that he pull all his power on that attack.

Issei: "That all you got?"

He didn't say a word, he still has his eyes wide and mouth open. Issei rush to Shalba and grab him by the next and throw him on to the ground and caused a crater. Shalba is now crawling out of the crater with a fear in his face and he doesn't have enough power to continue.

Issei disable his Juggernaut Drive and went back to his Balance Breaker. He fly down and walked towards the crawling Shalba. He kick him in the face making him lay on his back.

Issei: "Don't started what you can't finish, bitch."

He grab Shalba's head and throw him on the boulder and he spit out blood on impact of his back. He grab his wrist and stab it with the Blades of Chaos, pinning him on the boulder and he did the same thing on the other one. Shalba is now screaming in pain on top of his lungs, he tried to move his hand but he couldn't.

Issei is now punching him in the face, kicking him in the stomach resulting a broken nose and ribs. He then summons the Blade of Olympus and it made Shalba shock and realization.

Shalba(Shock): "T-T-That Blade! Y-Y-Your... H-H-Him?!"

Issei: "Yeah, The God of War."

He then thrust the Blade on Shalba's stomach and he's now screaming wildly. He then saw the remaining army of the enemy behind him and they were still many. He removed the Blade on Shalba and face them all.

Issei: "THIS WAR ENDS NOW!"

He gather his power on the Blade and he wave it diagonally, disintegrating them upon hit, leaving only their armor and weapons covered with their blood.

He then went back to Shalba with a face of Horror witnessing the true Power of the God of War. He then look at Issei, smiling and accepting his own death by his hand.

Issei: "You think that killing will let you rest? No. Killing you by my hands will only torture soul in deepest part of Tartarus for eternity."

Shalba(Shock): "Wha- NOOOO-"

Issei quickly cut his head off along with the boulder his leaning on. He unsommon the Blade of Olympus and grab the Blades of Chaos and disintegrate his body along with his head.

He disable his Balance Breaker and Unsummon the Blades of Chaos. All of the sudden he kneel down while looking a little dizzy.

Issei: "Guess I used too much power with that."

Ddraig: "Yes you did partner. If you weren't a god, you probably won't survive the transformation."

Issei: "Looks like I still need practice."

???Ise!"

He looked up and saw Rias with the ORC members along with Azazel flying down to him."

Issei: "Hey guys, you okay?"

Rias: "Were fine, what about you?"

Issei: "Never better."

Azazel: "I happen to receive that the enemies were having a back-up here, but I didn't saw them."

Issei: "I already take care of them. Look over there."

He pointed a field of armor and weapons coated in blood. They all look and shock what they saw.

Azazel: "Well, looks like we don't have to worry about that."

Issei: "Let's just get out of here, I'm too tired."

Rias created a Magic Circle on the ground and it teleport them back to the mansion leaving Azazel to clean up and see if there's any enemy survivor.

Issei: "Man, never felt so tired before."

Kuroka: "Hey you guys are back. How's the Rating Game?"

Issei: "It didn't go as plan."

Kuroka: "What do you mean?"

Rias: "The Rating Game has been cancelled for Diodora Astaroth has allied with the Khaos Brigade."

Kuroka: "What?! Shirone are you alright?! Are you hurt?! I'm going to make them pay if they even pull a single hair on you!"

She was hugging Koneko with their cheeks rubbing with each other.

Koneko(Blushing): "O-Onee-chan! I'm fine! They didn't hurt me! Onii-chan protected us from them!"

Kuroka: "Looks like I'm gonna give your Onii-chan a reward later.~"

Issei: "Why do I feel like I don't wanna know?"

Kuroka: "Hey Rias, can I talked to you in private?"

Rias: "Sure. You guys can rest now."

Issei's POV

Everyone went back to their rooms to rest while Rias and Kuroka went outside to talk about something. I went to the kitchen to find any food cuz all that fight made me hungry.

Issei: "Hey Tohru, can you prepare a me for me?"

Tohru: "Yes Master, what would you like?"

Issei: "Anything, I'm starving."

Tohru: "Okay Master, please wait a few minutes."

I went to the living room and watch some show on the TV while I wait for the food.

Tohru: "Master, the food is ready."

I went back to the kitchen to eat, but then I saw a very large roasted looking ham served on the table.

Issei: "Uhh Tohru... What is this?"

Tohru: "It's my roasted tail. Please enjoy, it's delicious."

I hesitated at first but I have no choice. I cut a small piece first and eat it, and it was better that I thought. It taste even better than ham.

Time Skip

After I finished Tohru's roasted tail meat, I went up to my room to rest. I went to the bathroom to wash myself and change my cloths too then I went to the bed a ready rest. All of the sudden I felt someone crawl on top of me, I open my eyes and saw Kuroka with a lusty face.

Issei: "Kuroka? What are you doing here?"

Kuroka: "Well Issei-kun, you already know that Me and Shirone are the last of my kind right?~"

Issei: "Yeah..."

Kuroka: "And we wanna repopulate our kind, and it just so happen that it's our kind's mating season.~"

Issei: "W-Wait, you mean..."

Kuroka: "Yup, were going to make some cute little kittens together.~"

LEMON WARNING!!

She smack her lips into mine and trying to insert her tongue inside my mouth but I grab her shoulder to stop her first.

Issei: "Is this what talk about with Rias?"

Kuroka: "Yup, and she understand though."

Issei: "Alright then."

I kissed her again and our tongue as are fighting for dominance and I won easily exploring my new territory. She sits on my chest and untie the the bow of her Kimono, letting it fall of her body and giving me a clear view of her chest.

Kuroka: "Like what you see?~"

I smirk and let her sit on my lap while I sit-up and suck her left breast while I massage her other with my free hand.

Kuroka(Moan): "Ahh!~ Yes keep sucking them!~"

I keep sucking her breast, left and right while she keeps rubbing her womanhood on my manhood trying to make it erect.

Kuroka: "It's unfair if I'm the only one that's naked here.~"

I lay Kuroka on the bed and I remove all my cloths only leaving my boxers making a tent with my erect manhood.

Kuroka: "Looks like someone's excited.~"

She crawled towards me and massaging my manhood with her hands. She then removes my boxer letting my erect manhood slap her face.

Kuroka: "Wow.~ I'm so going to enjoy this.~"

She stroke it first with her hands and licking the top of it. She then suck on the head and slowly sucking on the half of it. She started to suck faster and faster until I can feel the climax is coming.

Issei: "Kuroka, I'm close."

She keep sucking it faster until I release all my load into her mouth. Some of the load got out of her mouth but used her fingers and lick them.

Kuroka: "Yum~ Thanks for the appetizer~. Now it's your turn.~"

She lay on the bed, spread her leg while I started to finger her womanhood. She started to moan while I keep inserting my finger in her and playing with her clit.

Kuroka: "Ahh~Yes~ Keep playing with it!~"

I remove my finger and started to suck her while I insert my tongue inside of her. She keeps moaning louder as I keep sucking her and she grab my head to keep my mouth place in her. She then let out her load and I drink it all while she was panting on the bed.

Issei: "Can you still keep up?"

Kuroka: "Oh don't worry,~ I can still go for more.~"

I place my manhood on her entrance while teasing her.

Issei: "Are you ready?"

Kuroka: "Of course I am.~ Now stop teasing me and give it to me.~"

I slowly insert it and she gritting her teeth and gripping on the sheet. I fully insert my manhood inside her and saw some dripping blood and she has a tear on her eyes.

Issei: "Are you good?"

Kuroka:" Y-Yes, you can start moving now."

I started to move my hip back and forth while her breast keep juggling too. I grab her right breast giving it a good squeeze while my other hand is holding to hers.

Kuroka: "Ahh~ Yes~ don't stop~ keep pounding me!~"

I lay her sideways and put her foot over my shoulder and continue to pound her while she moaning. Her face becoming redder and redder while her tongue is sticking out and she was breathing heavily.

Kuroka: "Ah yes~ Issei~ your going to break me!~ Keep going!~ Destroy me!~"

As I keep on going, I can already feel that my climax is coming.

Issei: "Kuroka..."

Kuroka: "Do it!~ Inside me~ DO IT!~ RELEASE IT!~"

With a Final thrust, I release all my load inside her while she moan very loud. I remove my manhood inside her and the loads were dripping out of her and we were panting.

Kuroka: "Haa~ Haa~ That was~ Amazing.~"

Issei: "Yeah, I can now sleep."

LEMON END!!

She waits for a few minutes to wait, then she put on her panty and wore her Kimono again while I only wear my boxers back.

Kuroka: "See you Issei.~ Let's do that again sometimes.~ Cuz that was very fun.~"

Issei: "Yeah it was. See you too."

Kuroka: "Oh I forgot to mention, Shirone will be in mating season too. So she might need help.~"

Issei: "What?! Then what am I going to do?! I see her as a little sister. I don't know if I could do it."

Kuroka: "Don't worry, I can something about that. But she needs to release her mating urge or else she will lose.~"

She went outside of my room and closed it leaving me here thinking on what going to do about Koneko's situation. I'll just think of a solution somehow, for now I need to sleep.
