I know the last couple of chapters have been a little boring so this chapter we introduce a new villain to the mix. hope you all enjoy this chapter.

Issei PoV

"issei wake up." i heard Asia's voice call out to me. I slowly opened my eyes to notice Rias was already gone.

"you better rush down the courtyard, Rias has started training with Koneko."

"oh crap." i quickly jumped out of bed and changed into my tracksuit. i rushed down the halls to the courtyard at the back of the resort. i stepped outside to see Rias and Koneko standing there. wait koneko had cat ears.

"hey guys sorry i slept in." I caught my breath and listened to Rias' speech.

"as I was saying you need to tap into small amounts of your magical power, kind of like how issei can only access small parts of his power at a time. if you release it all it, your body couldn't handle it. understand?" she seemed to know her stuff.

"yeah I understand. so where do I start?" Koneko asked.

"hold your hand out." koneko did so.

"now close your eyes and imagine a ball of energy."

a small blue flame appeared in koneko's hand.

"concentrate." rias was determined, the flame grew and grew to fill her whole hand. suddenly the flame went out as koneko was not used to using her powers.

"that's a start, now issei I want you to boost your sacred gear and transfer some power to Koneko."

"sure thing. sacred gear!"

boost

I waited a few minutes before transferring the power to koneko. she focused again, creating another ball of fire. we both knew it would take a while for her to control her powers but it was a start.

"haha wait a go koneko!" I was so happy for her. we spent the day building her confidence and mana storage.

"Hey kids pack your bags we're leaving." Azazel yelled from the archway leading to the resort.

"I'm really proud of you koneko. we both are." rias smiled.

she stayed silent but did smile as she went to her room to pack, within the hour we were summoning a magic circle home. the red mark of gremory enveloped the floor as we teleported to the clubhouse. there was an unfamiliar figure sitting in rias' chair. he wore a open black coat and dark jeans. his hair was pitch black medium length and he had bursting purple eyes, he looked around the same age as Issei.

"oh hello there." he chuckled.

"huh? who the hell are you?" I shouted.

"I'm Lannister, I'm here to tie up loose ends." he smirked with a devilish look in his eyes.

"what do you mean?" Rias was trying to remain calm.

"Does the name dominion ring a bell?"

Rias' eyes widened as she heard a familiar name hit her ears.

"as in the long lost devil house?" she seemed a little shocked.

"you'd be correct, now let me tell you a story. years ago during the war, there stood a house so loyal to there kind that countless of their members were slaughtered fighting for their kind. the dominion household was one of the best battle houses around, their forces strong and reliable." I didn't like where this was going.

"after the great war and after losing so many members the leader of the household, Magnus Dominion decided they deserved a spot among the great Satans. he was refused causing him to become aggravated, he decided that if they wouldn't allow a fifth great Satan then he would take it by force. luckily the household agreed with him and they planned to overthrow the sitri household. unfortunately their attack failed and the house of gremory sent a counter attack and almost completely wiping out the entire household. two children survived and were exiled to the human with their memories and powers sealed away. these two were brother and sister and they were sent to an orphanage to live a regular life."

"years after an organization called the chaos brigade was formed, the war had left the four great Satan households in shambles and some were even without a leader. so members of other households filled the gaps to restore balance. the chaos brigades mission was to restore power to the rightful heirs of the households. the members included members from the original great Satan clans as well as people who shared their views, giving them great numbers. one night a man contacted the two children telling them that the life they were living was a lie. he unlocked their memories and let's just say it wasn't pleasant. after seeing the gruesome deaths of his household the boy became a little.. broken. the girl didn't handle it well either, she felt lost and depressed. both affected by these memories they decided to join the chaos brigade. they were young but powerful and they grew up within the chaos brigade. the boy wanted revenge and for years he stood by waiting for chance to avenge his fallen household. he grew tired of waiting, he decided to go after them himself and here we are." he grinned

"I am Lannister Dominion and I will avenge my household."

rias stepped forward to stand only metres away from Lannister.

"so your here to destroy the house of gremory because your own household was hungry for power? because they didn't get what they wanted so they planned to overthrow the sitri household, our closest allies?" rias shouted. she was not happy.

"hey we had earned our spot among the great Satans!" he was beginning to getting aggravated.

"Azazel alert my big brother, I want to know if what this devil speaks is true."

"understood I'll be back, stay safe you kids." he disappeared leaving the peerage alone with Lannister.

"I'm surprised a devil so young as you knows of our household."

"I don't know much but I do remember reading about your household in our archive."

"hmm interesting." his mood could change so quickly one minute he was aggravated, the next he was calm.

"well even if you somehow managed to defeat us them you'd have to deal with the rest of gremory household."

"you think I'm scared of the house of Gremory? the chaos brigade have given me immense power." he cackled.

"you will soon regret coming here." Rias was getting mad. I stepped forward to stand by rias, our hands locked together and my gauntlet appeared on my other hand.

"oh what's this? the red dragon emperor and the ruin princess? haha don't make me laugh."

boost"I'm gonna kick this guys ass." I said gritting my teeth.

boostoh really? coming from supposedly the weakest red dragon emperor to date." he said.

boost"don't piss me off." I was getting angrier by the second.

boost"well then let's get this going." he stood up, looking at us with evil eyes. suddenly two revolver style pistols appeared in his hands, a purple fire like aura surrounded them.

"that's right I have a sacred gear too. it's called Hellfire Revolvers."

boost"you think thats gonna stop me from kicking your ass?"

"let's find out." he said laughing maniacally. he began firing shots, the bullets were surrounded in purple energy and they were coming my way. I tried blocking with my gauntlet but a bullets managed to curve and clipped my arm.

"ahh what is this? it just brushed past my arm." I felt immense pain, I could feel a burning feeling through my whole arm.

boost

"issei!" rias shouted.

"if my bullets make the slightest contact, they begin to burn from the inside outside."

"but it was only a damn scratch!" the pain was getting worse.

he just laughed before taking aim at Rias. I stepped in front of her, ready to take the hit.

"oh? do you really wish to die?"

"I'm not gonna let you hurt the people I care about."

boost

"oh how cute, then prepare yourself." he fired again and this time I was ready, I was aware of his curving bullets but I was determined. I once again blocked with my gauntlet, this time blocking every single shot.

"alright everyone let's help issei out." rias commanded. kiba and xenovia were the first to move and koneko soon followed. akeno changed into her kimono and Gasper hid behind Asia.

"tell me issei, why do you care about these people?" Lannister still seemed so relaxed.

"because these people have helped me grow and progress... and above all... These people are my friends!" I said trying to ignore the ever growing pain in my arm.

boost

"heh friends.. what use are friends? you'll soon realise you can only rely on yourself."

"what about your sister? don't you care about her?" I asked.

"my sister? I haven't seen her in quite some time. good riddance." he smiled.

"what do you mean?"

"well as we grew up in the chaos brigade, I became more powerful. my sister and I were very different, I enjoyed the thrill of combat while she preferred to read. I will admit that her magic was not to be underestimated. then one night, she woke me and said that we needed to go. i refused to leave i had everything i wanted. i had power, drinks, women, anything i could ask for. she begged me to come with her but i had outgrown her. she decided to leave anyway, i tried to stop her but she managed to slip away." he quieted down.

"but i dont need her, i never needed her. i dont know where she is and i dont care. all i care about is avenging my household!" he went back to that psychotic state and opened fire on kiba and xenovia. they quickly began dodging the incoming bullets that lasted what seemed like forever. koneko wasnt in the direct line of fire so she rushed forward trying to stop Lannister. he quickly noticed turning his attention to her. she was unable to press forward with the barrage of bullets heading her way. she was defenseless. the bullets then froze and dropped to the floor. it was gaspers doing.

"thanks gasper." she turned around quickly to thank him before retreating back next to me.

"listen up you heartless asshole, if you wanna hurt the gremories then your gonna have to go through me." I stepped forward demanding a challenge.

"oh just how stupid are you?" he laughed.

"oh shut up you cocky prick." I shouted.

"fine but let's take this outside." he clicked his fingers and the whole group was teleported to the soccer court.

"let's finish this you piece of shit." I stood there ready to take him on.

boost"let's begin." he took firing a couple shots. I blocked with my gauntlet as I ran towards him.

boosthe fired more rapidly and his bullets began to curve past my gauntlet. I managed to Dodge in time and keep going.

"haha are I lucky to be gifted with hellfire revolvers? not only do they burn with hellfire but they can curve around corners or even shields.""I'm still gonna kick your ass!" I said beginning to rush towards him again. he fired again but this time I swatted his bullets away with my gauntlet.

boost"hehe fine." he smiled taking aim at Rias.

"oh no you don't you asshole." I began to sprint towards him but I wasn't fast enough. he fired, the shots flew through the air with trails of purple fire. they were closing in on Rias, suddenly xenovia stepped in and blocked the bullets with her sword.

'she's okay... oh that asshole.' I thought.

boost

"alright you piece of shit your going down, no one hurts the people I love!" I shouted before feeling a surge of power awaken within me. thoughts and feeling of the girls flooded my mind as my power grew.

'this is for you girls.' I thought. a red light surrounded me and I could feel immense power.

Rias PoV

'wow.. issei's gonna do it.' I thought feeling proud of my little pawn. I could sense such strong power emanating from him. suddenly the power exploded, revealing scale mail.

Issei PoV

"I told you, you asshole that I was gonna kick your ass and I intend to do it." I said confidently.

"oh that makes it interesting." he maniacally cackled.

"laugh all you want but you're going down." I said slowly as calmly walking towards him.

"haha you think you can stop me? from what I hear your still pretty weak." he said smiling.

'oh this guy is such an asshole.'

suddenly he fired towards me but the shots just bounced off my armor, his cocky expression faded showing a more serious attitude.

"fine. take this!" it seemed like his guns never needed reloading, he fired dozens of shots only for them to again bounce off my scale mail. I dashed toward with help of my wings and quickly struck him right in the stomach, he coughed blood before he was sent flying a decent 10 metres.

"alright you're a little tougher than I thought but don't let it go to your head." he said wiping the blood escaping his mouth.

I once again dashed towards him ready to strike once again.

"you think dragon scum like you could defeat me?!" he poked his tongue out reminding me of Freid. I continued towards him, readying my fist. he just stood therem laughing.

"ascalon!" I shouted.

the mighty blade appeared as I grew closer to Lannister.

"balance breaker!" he shouted.

a beam of purple light engulfed lannister for a few seconds before disappearing into the sky. His pistols had grew into cannons and emitted a far more deadly aura now. he took aim at me and fired, the giant purple bullet came speeding towards me. I didn't have time to dodge it. the bullet hit me directly in the stomach sending me flying, I again felt the burning effects of his sacred gear. it felt like my body was on fire, I smashed into the ground but kept sliding a few more metres before coming to a stop.

"this guy is an asshole!" I stood up enduring the growing pain shooting throughout my body. I dashed towards him once again ready to strike.

"haha first I'll kill you then I'll kill all your friends!" Lannister just laughed as i bursted towards him.

he fired his cannons but I dodged easily before continuing to stream towards him, but I soon felt another burning pain hit my back. his bullets had done a complete one eighty. I smacked into the ground again, this time my helmet shattered.

"issei!" Rias began running to my aid but Lannister took fire on her too. I struggled to move feeling the burning intensify. This feeling was like nothing I've felt before, with every second it got worse. I again stood up feeling like I would collapse any second.

"all this training I've done, I won't let you ruin that!" I roared ready to defend Rias with my life. I bursted towards her ready to take the hit myself.

"issei?" she asked.

I just smiled as the bullets closed in. suddenly a red magic circle appears in front of us.

"not this time." a familiar voice said.

"brother?" Rias asked.

"im glad I made it in time." sirzechs appeared in front of us before easily absorbing the blast.

"Azazel I still don't understand why you couldn't handle this one yourself." sirzechs seemed annoyed being disturbed from his duties.

"hey your sister asked me to come get you." Azazel replied.

"hmm why did you call me here then Rias?"

"this devil claims he's part of house dominion." Rias pointed at Lannister.

"hmm an interesting claim, well then are you really apart of the dominion household?"

"you think I would lie about my origins?" he just laughed as usual.

"well do you have proof?"

"does this prove it?" Lannister summoned his magic circle.

"interesting I thought your household was destroyed."

"don't you mean murdered? by their so called allies!"

"*sigh* alright listen here I've been interrupted from my busy schedule to come out so I'm really not in the mood for this." sirzechs was becoming stressed.

"ugh I'm gonna kill you all!"

"I'll end this quick-"

"no! he's mine!" I roared.

"issei?" Rias was shocked.

"I can't let everyone fight my battles for me, and more importantly... he made it personal!" I was ready to fight once again knowing that even if i failed, everyone else would be safe.

"hahaha you still think you can beat me? then come at me!"

sirzechs seemed to understand my grudge and decided to step back leaving Lannister to me.

"Issei.. be careful." Rias hugged me tight. i could feel my love for her starting to give me strength. I smiled as my helmet reappeared.

"let's finish this Lannister!" I charged towards him.
