Me and Ignisia were out at an open field near the mansion today for some light training. "Alright (y/n) you ready for some training." Ignisia said. "Yeah but I got a question Ignisia." I said. "Shoot kiddo." She said. "It's about Arrax what's he like." I said. "Ahh Arrax he's the most passionate one when it comes to combat and the more outgoing one out of all us." Ignisia said. "I see." I said. "Curious about him huh." Ignisia said as I nodded. I started doing some normal side stretches making sure my body isn't sore for today's training with Ignisia. "Alright (y/n) since you're able to draw out the six crimson dragon heads. I want to see if you can draw out the crimson dragons armor and weapon it doesn't have to be like mine exactly but of how you would envision it." Ignisia said as I nodded imagining what would it be like.

Ignisia was watching (y/n) seeing her focus feeling the crimson aura coming from (y/n). "She's training with you." Vurmi said coming out. "Mhm how's Arcion." Ignisia said. "He's recovering after getting a lecture from Tiamat on hurting her daughter." Vurmi said seeing a red light form around (y/n) revealing her armor.

"Wow." (Y/n) said looking down. "Need a mirror." Ignisia said as made a mirror from magic which gave (y/n) a full view of the armor. "So this is my version of the crimson dragons armor." (Y/n) said looking at it. "That's one of two steps now try to imagine what you believe in to be a weapon of your power." Ignisia said as (y/n) raised her hand focusing of what she believes her weapon should be as a red light shined revealing a spear.

"Twin spears." (Y/n) said twirling one of them. "Impressive." Ignisia said as (y/n) de-summoned both spears and her armor going back into her normal clothes. The sky soon turned red which Ignisia, (y/n) and Vurmi confused. "The sky is red." Vurmi said. "I don't why I just have a bad feeling." (Y/n) said. Ignisia closed her eyes sensing any signatures within the area. "Something big is happening at your guys school." Ignisia said. "What do you mean." (Y/n) said. "Very high Holy energy signals could be Arrax but this one is very sprawling you two should go over there." Ignisia said both Vurmi and (y/n) looked at each other and nodded. "Alright big sis." They both said as Ignisia hugged them. "Be careful." Ignisia said as the two of them ran straight to Kuoh Academy.

Me and Vurmi made it to Kuoh academy seeing a barrier around it. "Sona what's going on." I yelled which got her attention. "(Y/n) , Vurmi you guys made it Rias and the others are fighting a high ranking fallen angel." Sona said. "Open a small part of the barrier tell them we're on our way." Vurmi said which Sona nodded opening a small part in front of me and Vurmi as the two ran to the back part of the school seeing the high ranking fallen angel with Rias and her group.

"Rias." I yelled. "(Y/n) , Vurmi." Rias said as a light spear came at me and Vurmi. I used my new spear slicing it in half. "Oh your an interesting one." The fallen angel said with a smug look. "Who the heck is this guy." I said as Jué came out of the pendant. "Kokabiel." Jué said with venom in her voice. "Ahh Jué it's been a while." Kokabiel said. "Jué you know him." I said. "He's the one who killed your father." Jué said. "It was wonderful hearing his screams his wife was in distress when she saw his head on a pike." Kokabiel laughed maniacally. "(Y/n)." Vurmi said I gripped my fist. "Maybe I should kill her daughter next." Kokabiel said my anger building up letting out a load roar.

"KOKABIEL." (Y/n) yelled using her flash speed impaling kokabiel only for her to also get impaled by his light spear making her cough blood. "(Y/n)!!!" Vurmi said as (y/n) delivered a punch to Kokabiel coated in crimson energy sending him back crashing into the ground. She removed the light spear from her chest. "I will kill you Kokabiel!!!" (Y/n) yelled inhaling the air then letting out a Lighting blast.

"Arcion's Lighting Roar." Vurmi said shocked. "How was she able to learn it so quick." Jué said. "Her battle with Arcion." Vurmi said she felt (y/n)'s aura spiraling out of control. "Oh no." Vurmi said seeing black marks on (y/n)'s body.

"Is that." Jué said. "Black Dragon Force." Vurmi said. "Not even I could master that." Vurmi said. "Wait Dragon Force." Issei said. "It's equivalent to a balance breaker but this one is that of pure malice." Vurmi said watching Kokabiel come out. "Interesting now this'll bring me to kill you more." Kokabiel said throwing a light spear at (y/n) impaling her. "She's not even fazed by it." Rias said. "Because she's so focused on killing Kokabiel." Vurmi said summoning her companion. "If she continues on she might die." Jué said. "Which is why I will stop her." Jué said flying to (y/n) standing in front of her. "(Y/n) stop this won't get you anywhere." Jué said trying to get her which (y/n) let out a black roar hitting Jué.

"JUÉ." Vurmi yelled which the roar slightly injured Jué. "But a scra-." Which Jué coughed blood seeing the end of a light spear in her chest. "Why don't you drop." Kokabiel said shortly then removing the spear which slowly brought (Y/n) back to reality. "Jué." (Y/n) said seeing the hole in her chest. "It good to see you again (y/n)." Jué's words were slow as she fell a top (y/n). "Jué Jué." She was in a panic. "Vurmi." (Y/n) said slowly coming down. "Take Jué to Rias' bishop." (Y/n) said. "What about you your injuries." Vurmi said seeing the hole in (y/n)'s chest. "I'll be ok the jobs not done." (Y/n) said going back to fight kokabiel.

Rias and her group didn't know what to do as all they could was watch (y/n) fight kokabiel. "Rias." Vurmi came up to them holding Jué. "Can your bishop heal her." Vurmi added Rias nodded as Asia came up and used her twilight healing to heal Jué's injury. They watch (y/n) throw kokabiel up into the air then letting out a black dragon roar on full blast. "That's what you get for doing that to Jué." (Y/n) said coughing up blood going on one knee. "(Y/n)." Vurmi said running to her. "I'm ok how is Jué." (Y/n) said. "She's recovering Rias' bishop is healing her." Vurmi said as they heard maniacal laughter. The duo saw a priest holding a sword made of holy energy. "You two are easy targets die!!!" The priest said about to slash Vurmi and (Y/n). Vurmi held (y/n) in a protective manner. "HOLY DRAGON ROAR." A voice said.

"That Technique." Vurmi said seeing the person turn and face them. "Seems I made in time Vurmi." Vurmi saw that it was her older brother. "Arrax." Vurmi could only cry as (y/n) could only close her eyes with last she saw was the person named Arrax.
