The Dragon Slayer ( highschool dxd x mreader)

Dual

As soon as we get to the school, Sona and her household create a defensive barrier. "This barrier is designed to protect the school. If nothing drastic happens, it should be able to keep anything within it from being damaged." Sona explains. "Thank you sona this means so much." Rias says. "Understand that this will work if conditions remain the same." Sona says. "Got it." Rias says and tsubaki appears. "Tsubaki. How's irina?" I ask. "Her condition is not life threatening. She thank you and Asia for that." She says. "What a relief." Asia says. "Where's xenovia. I wonder if she'll even show." I say. "Have you heard from Kiba, either?" Saji asks. "No, not at all but I know he'll show." I say and koneko agrees. "I'll keep the barrier up and keep the school from collapsing. As much as I'd like to avoid it." Span says. "I'm not going to let that happen." Rias states. "Rias, it's not too late. You can still contact your brother." Sona tries to convince but Rias shakes her head. "You know what I don't see? You trying to contact your big sister." Rias says. "With good reason too. Sir Zechs loves you. He'd want to assist us. There's no doubt he'd come here as soon as you called so call him." Sona states but then Akeno shows up. "There's no need. I've already contacted sir Zechs." Akeno says. "How could you do that without asking me first?" Rias asks. "Look Rias, I understand that you don't want to bother your brother unless you absolutely must. Our enemy is a leader-class fallen angel. He's not someone you can take on your own. I think that qualifies this as a must." Akeno says and Rias just agrees. "I thank you for your consideration, president. Sir zechs is on his way. I believe his forces should be here in just about an hour." Akeno says. "Good grief girl. I cannot win against you, can I? Should be a fun hour." Rias says.

"Issei, I want you to be on support this time." Rias says. "Support, what for?" He asks. "I want you to transfer your power to the rest of us to increase our strength." Rias explains. "No problem. I'm all over it." He says. "In the meantime I think we can stall for time until issei can transfer his power to everyone. Don't you?" Rias asks us. "Yeh I bet we can manage that." Akeno agrees. "Absolutely." Koneko agrees. "(Y/n)." Rias calls me out. "Yes, I'm here." I say. "Yes and we're also counting on you as well, concentrate on being on the offensive, remember we have to try to prevent kokabiel from releasing his power whatever that may be. Unlike the fight with riser, our lives will be at risk. But I will not allow that to happen. We will survive my dear servants. We will survive so that we can go to school once more." Rias says and we all agree. "Promotion: queen." Issei and I say. When we head outside we see a large wave of light. "What in the hell is that?" I ask. "It seems that four of our five Excaliburs have been made into one. That is just so valper you know." Kokabiel says from his high throne. "Kokabiel!!" Rias exclaims. "Sonia big brother on the way or is it serafall instead?" Kokabiel asks. "Right now, we're the ones ready to fight. That's all that matters." Rias says and kokabiel throws a spear of light at the gym obliterating it. "Ugh this is so boring I need a diversion. That reminds me...dragon slayer king ...here." He says throwing a sword still in its sheath down. "It's my brother's sword, but why?" I also. "Apparently the Excalibur sword of hope is useless in the hands of pure evil, so none of us could get it out of its sheath." Kokabiel explains. "Bastard...so you raided his grave just for nothing." I growl but still tremble at what he did to the gym. "WHATS WRONG KID YOU SCARED?" The dragon kings ask me telepathically. "I've never seen that big a lance made of light before, it's like it comes form a different dimension." I explain. "OF COURSE ITS FROM ANOTHER DIMENSION. LOOK AT HIM. WERE TALKING ABOUT A MAN WHO SURVIVED A BATTLE WITH GOD AND THE DEVIL KINGS." They say. "You think we can still beat him?" I ask. "WHEN IT COMES DOWN TO IT. WE WILL BEAT HIM EVEN IF WE HAVE TO TURN MOST OF YOUR BODY INTO A DRAGON." They say. "Wait like that time against riser?" I say going back to the fight against riser. "INDEED. ARE YOU IN?" They ask. "You bet." I say. "Since you came all this way to see me, I might as well let you play with my favorite pets." Kokabiel says then making a pit of fire opening up and out of it comes..."Cerberus?" Rias says. "Living at the gates of the underworld. It's the watchdog of hades." Akeno explains. "So he's real? What are we going to do?" Asia asks. "Bringing him to this world is forbidden. Let's send him back. (Y/n), Akeno, Koneko." She says. "Yes ma'am." We say. "Issei use the sacred gear to enhance our power." Rias orders. "Boosted gear." He chants bringing his dragon hand out. "Power up: lightning drive." I chant covering myself with a veil of lightning and akeno changes into her shrine maiden uniform. "Issei watch Asia for me." I asks him and he agrees and just like that the Cerberus let's put a fire attack akeno freezes it and Rias throws her destruction magic at it. "I think he wants more." Akeno says throwing some lightning at him. "LIGHTNING DRAGON ROAR!" I chant releasing a stream of lightning at it. Just then I hear a scream and see a Cerberus going after Asia but luckily issei rescues her in time, he then decides to let it chase him but koneko cuts in. "Koneko look out." Issei says. "You look out I'll deal with this." She says and it takes a bite out of her but has its teeth broken in the end. "Are you alright?" Asia asks koneko. For the most part." She says. "I'll take it from here. Hey you piece of shit dog cant tell your enemy's standing right here?" Issei baits the Cerberus and it chases him. "I think you pissed it off. Let me help. POISON DRAGON..." I say punching its back. "GOUGE HORN!!!" I finish releasing a poison cloud inside the Cerberus body but it shakes me and the poison off and is about to take a bite out of me.  But then one of its heads falls off. "You need a little help here?" Xenovia asks cutting it apart. "Now that is exactly you can expect a holy sword to have on evil." Akeno says. "I'd rather we didn't need the help but I am glad  you're here." Rias says. I then see isseis hand glowing. "Heads up guys." Issei says. "Good boy." Rias says. "Ooh fun." Akeno says. "Might as well take that power up." I say. "Boosted gear gift." He chants and all of sudden I feel more power running through me. "Thanks I'll add to it. Enchantment magic: arms, armor." I chant. "What happening." They moan. "This dragon slayer ability allows me to boost both offense and defense. I forgot about it until recently." I explain. "Interesting I had no idea you were strong enough to do that." Xenovia says. "We're ready now." Rias says. "Oh yeah." Akeno agrees. "Akeno, do it." Rias orders. "Of course. I'll bring out THUNDER." She says summoning her lightning attack and we beat the shit out of one of them but one is close to Asia but suddenly a bunch of swords emerge and pierce it from below. "Kiba made it." Rias says as he appears. "More!" Rias orders. "I would love to." Akeno says throwing her lightning. "Don't forget me. WHITE DRAGON HOLY BREATH." I chant releasing a widespread breath attack and Rias throws her magic circle fusing and enhancing our attacks erasing the Cerberus that remained. "Awesome." Issei says. "Awesome is a bit of a stretch." Kokabiel says. "TAKE THIS!!!" Rias says throwing a large demonic blast at kokabiel but he simply waves his hand at reflects it at the tennis court leaving nothing but a crater. "Impressive, look how much stronger you've become now that you've had both red dragon emperor and sky dragon enhancement in you. Sexy and fascinating as well." Kokabiel says. "It is complete." Valper say. "Oh no." Kiba says. "Finally it is done." He says maniacally
