We teleported from the underworld to the human world. "What ever is gonna happen from what you told me yuki I know it's not gonna be good." As we all ran to kuoh academy. We soon made it seeing sona and the others holding up a barrier. "Sona." I yelled. "(Y/n) how did you get here." Sona said. "What's the situation." I asked her. "Rias and the others are handling a person by the name of kokabiel." Sona said. "Open up the barrier me and my peerage will help Rias.." I said as sona and her group nodded opening a slight crack in the barrier. "Let's go." I said to my peerage. "Hai." They all said as we ran to the source of power.

(Y/n) and his peerage ran to the field as he saw what this kokabiel person looked like.

"(Y/n)." Rias said as (y/n) saw the death known as Cerberus Hades lap dog curious for this guy was able to summon him. "To think I would see a faulty sword something that is unpar with the real one." (Y/n) said. "You got quite the words mind telling me your name." Kokabiel interested in (y/n)'s sudden appearance. "I am (y/n) Phoenix heir to the Phoenix household." (Y/n) said. "Haha you might be an interesting fellow to fight those to that of the ruin princess, the daughter of Baraquiel, a holy sword project subject, and a red dragon emperor." Kokabiel said. "Yuki I want to cast corruption on me." (Y/n) said. "(Y/n) don't tell me your gonna." Sakura said. "I'll need a good amount of power to summon this thing." (Y/n) said as his right eye lit a blaze. "Very well then corruption." Yuki blasted corruption at (y/n) appearance began to change.

"Ngh." (Y/n) said taking in the corruption. "Boss." Ban said. "I'm fine I've only done this once now COME MORGAN!!!" (Y/n) screamed slamming his hand down as his magic circle came but was more corrupted revealing a sword of dark magic.

"What is that." Rias said looking at the sword that (y/n) wields as she can feel the corruption coming from (y/n). "Haha interesting interesting I think you give me a promising fight now come." Kokabiel said as the two clashed.

"The amount of power coming from (y/n) and that sword what is that." I said looking at (y/n) and kokabiel fighting one another. "It's the first time seeing a sword like that as well neither holy or demonic but straight corruption." Kiba said. "It's known as excalibur Morgan a more corrupted version to the original excalibur the one (y/n) wields is not the original Morgan but more of a construct version of the sword the original excalibur Morgan." Yuki said. "If he were to wield the original Morgan his mind would be more corrupted." Sakura said.

"Still when he first tried to wield his construct Morgan he last barely for five minutes." Yuki said. "Boss was able to last that long." Ban said watching. "He's about to burn out." Sakura said as she can see (y/n) breathing heavily. "Is that all you got Phoenix boy." Kokabiel said laughing. "Is still got one trick up my sleeve." (Y/n) said as he reached his hand out near kokabiels face. "Blast." (Y/n) said blasting flames point blank at kokabiel.

"That's what you get bitch." (Y/n) said coughing a bit of blood. "Boss/(y/n)." His peerage said. "I'm fine seems that blow was enough damage." (Y/n) said. "You interest me boy but seems it wasn't enough." Kokabiel said coming out with burns. "(Y/n)." I said screaming at him. "Heh we didn't know each other that much issei and yet your worrying." (Y/n) said. "You bastard you promised we would fight sometime." I said. "Don't worry I'll be back." (Y/n) said as a light spear was pointed at him. "(Y/n)!!!" Kaori yelled as a hooded figure came at the right time.

"W-w-who are you." Kokabiel said as the radiation of power was so toxic to everyone. "Yuki cast holy immunity." (Y/n) said as yuki did as told. "My name is Saber I sensed the power of Morgan near so I've decided to come check." Saber said as she looked to see a destroyed excalibur. "To think you would copy the real thing." Saber said unsheathing her blade. "This holy power." Kiba said. "That's the real Excalibur." Rias said. I watched as this saber person and kokabiel were fighting against each other (y/n) was incredible but this saber person was on a whole other level. Seeing her deflect his spears like they were nothing this saber person must be powerful. She put kokabiel in a corner as I felt a strange signature. "He's here partner." Ddraig said. "What." I said as I looked up seeing a white figure donning white armor. "What is the white dragon emperor doing here." Kokabiel said as they came in like a speeding bullet taking kokabiel around like a ragdoll.

"(Y/n)." I looked to see my peerage come to me. "That was too reckless." Sakura said. "I know but that's the white dragon emperor." I said looking up seeing him rip the wings of kokabiel. His ruthless nature and that of knowing the sacred gear divine dividing a very useful sacred gear indeed. Seeing him defeat kokabiel as he picked up the unconscious priest as well I saw issei go on a tangent about he was gonna win and suck on Rias' boobs. "Was he this much of a perv." Yuki said. "Oh you know it sister." Koneko said. I watch as the gauntlet and wings have a conversation about their fated battle as the vanishing dragon emperor left with kokabiel and the priest.

"Nice job Rias and company." I said being helped up by yuki and Sakura. "(Y/n) think you'll be ok." Issei said. "I'll be fine yuki's corruption ended when I was at my limit with Morgan." I said as I looked at this saber person. "You were the one who was able to summon Morgan." Saber said. "It wasn't real but more of a construct." I said. "But still real or not that is a sword of pure corruption." Saber said. "Ban when we get home please make a lot of food." I said. "You got it boss." Ban said. "Did you say food." Saber said. "Y-yeah." I said seeing how she can go from serious to thinking about food. "Rias since everything is under control me and my peerage will be heading home." I said. "Yes and thank you for the help." Rias said as me, my peerage and saber went to our home.

We came to our home as ban went into the kitchen to start cooking as I sat on the couch with saber sitting across. "Who are you really saber." I said looking at her. "My real name is Artoria Pendragon or what the humans call me is King Arthur." Saber said. "Based on the legend but why are you in the modern world." I said looking at her. "After the battle and the killing of my son mordred I died on the battle field but was slowly reincarnated as a wanderer." Saber said. "So you have nowhere else really to go." I said as saber nodded. "Well we have extra rooms." I said as yuki whispered in my ear. "Well crap seems we don't have extra rooms and the only room their is is mine." I said. "I don't mind I was also wondering if I can join your group." Saber said. "You mean peerage?" I said. "Yes." Saber said. "Are you sure you want to give up your human life to be reincarnated as a devil." I said. "If that is something that I would be willing to sacrifice then yes." Artoria said. "Very well." I said holding a knight piece as I began to chant the ritual. The piece slowly entered artoria's body as she felt a slight sting.

"There the process is done welcome to the peerage saber." I said looking at her. "Thank you master." Saber said as I remember my rule as I sighed to let it slide. "Everyone dinner is ready." Ban said as everyone gathered around the table. "Whoa." Sabers eyes shines seeing the amount of food on the table. "Thanks for the meal." We all said as we began to eat. "So boss that thing you did against kokabiel that corrupted sword you were able to pull." Ban said. "Excalibur Morgan a very corrupted sword indeed something that works when highly corrupted." I said. "Morgan is a sword that is something that can't be trifled with." Saber said eating. "The reason I was able to summon it was through the history of your legends and seeing how regrets and emotions play a role." I said. "But still Morgan runs heavily on anger and everything that is negative compared to that of Excalibur." Saber said as we began to talk about the two swords until we had to clean up.

I was in my room thinking about Excalibur Morgan and my immortality as a member of the Phoenix family. I sighed thinking about it and how to use Morgan properly. "(Y/n)." I saw saber walk into the room. "Oh saber your done with your shower." I said getting up and taking a futon on and set it on the floor. "What are you doing." Saber said. "I'm sleeping on the floor you can take the bed." I said patting it down. "But you can't." Saber said. "As your king I request you take the bed." I said as saber nodded and took the bed while slept on the futon.
