5. Chapter 5 True Power Revealed

Chapter 5: True power Revealed.

Its time the 4 days are up and I am in the Hyuudo viewing room getting ready to leave. Everyone is here and Ajuka is getting everything set up for everyone. He has already informed the leaders of this. Today is the day i defeat Trihexa.

"We rushed to finish it," Griselda says as she hands me the Holy Aegis. "I hope it will." I place the shield on my back.

"I hope so too," I say to her. "Sadly the gift from the Greek gods could not be rushed." I had everything i needed now.

"Everything is ready," Ajuka says and turns everything on. After a few seconds the screen shows everything that is going on in the barrier.

"What is this?" Sister questions Ajuka.

"That is a live feed into the barrier where the leaders are fighting Trihexa," I say to her. "Brother, I will be showing up in a few minutes. It seems my hand was forced earlier than expected."

"I understand," he says and appears on the screen. "Hello everyone, sorry to keep you in the dark about this but it was for your safety. Only Issei was allowed to know until earlier this month when Cartil reappeared during one of the Ajuka and Azazel's chats. Please do not be mad at them."

I create a teleportation circle. I look over at Grayfia who seems to not know what to say. Ri runs up to me and jumps onto me. I hold her. "Daddy, be safe," she demands. I pat her head and smile.

"I will beat this monster, so you can meat your uncle," I say to her and hand her to Hanalil. "Well i am off." I set into the circle and disappear.

I arrive at the location were brother and Issei fought the core of Trihexa. I start to create a special teleportation circle. "Everything we have been working for is about to happen, are you ready partner?" I ask Kronus.

"Let's do this," Kronus says to me with fighting spirit. I set into the teleportation circle.

Part 2

I arrive in the barrier. My first sight is the monster Trihexa. It is a lot uglier in person. I turn and walk to the leaders. I can hear from the other side that people are glad I made it. I place down the supplies I was given by Ajuka to give to the leaders.

"Good to be resupplied," Zeus says.

"Cartil its good to see you again," Serafall says and hugs me. I smile. Souji walks up to me.

"Master," I say and kneel.

"Stand Cartil," he tells me. "For today you are the master." I stand up and nod.

"I assume you have a plan," Odin says as he walks up.

"I always have a plan," I inform him. "You stay back and let me handle this. You all need rest anyway. Now would also be a good time to talk to everyone on the other side." I turn to Trihexa and slowly walk towards him. "Time to test your regeneration." I charge forward.

I ignite my fist in the power of destruction and slam my fist into the first head. The head blows apart and jump back. I watch as the regeneration starts slow and reform the head. I could probably do it two more time before it because super fast again. It then strikes at me and i jump back even further. I am barely able to dodge. I jump back again and lift my hand into the air. Storm clouds appear and lightning begins to arc between the clouds. After awhile the lightning changes to red and move my hand down. I point at Trihexa and lightning blots strike its entire heads, they blow up.

It begins to regenerate all of its heads. After it regenerates its heads it goes after me again. This time i don't dodge but i counter attack with my power of destruction infused fist. The impact sends me flying backwards and blows up its attacking arm. I land and slide back before falling to a knee. It has already regenerated the arm. My calculations are way off. This is very bad. I can't use the new swords yet. I place my hand on the ground and create a summoning circle. Once it's done i quickly grab the sword handle and pull it out.

I jump to the side barely dodging another attack. The monster is pissing me off. I point the sword towards Trihexa and focus my aura into the blade. The blade ignites and slam into the ground, the ground under Trihexa explodes from the power of destruction. Its body takes massive damage, its struggle to regenerate with this attack. I am now breathing heavy. "Crap that attack took way more stamina than i thought," i say. "This is not good."

As I am recovering, Trihexa is also regenerating from the attack now. I reach back and grab the Holy Aegis. I strap it to my left arm. "It can't be," I hear Michael in the background. "God's Holy Aegis?" I can then hear Griselda explaining things to Michael. Trihexa is now fully restored and strikes at me again. I hold up the shield to block it. Once it hits the shield it ignites in holy white flames.

"Yes it worked," I comment. I charge up my sword again and slash down, sending a wave of energy at it before it can adapt to the holy flames. I cut it in half and as it tries to regenerate i jump back. I toss my sword back and it implants itself into the ground. I place my hand on the ground and summon another sword. I grab the sword and activate its power. It ignites in purple and black flames. Trihexa has recovered and is coming at me again. I run at it and slide under its attacking arm. I jump up and slice its arm off. The arm that has fallen off bursts into flames and disappears.

"I hold in both hand the ability to purify someone to death in holy flames and the ability to curse someone to death with the cursed flames," I comment. I then get hit by another one of its arms and i sent back towards the leaders. Brother catches me. The sword and the holy aegis fall to the ground. He sets me down and then I notice I am bleeding badly. "Idiot, I let my guard down, stupid rookie move. Screw safety at this point. I have to use that power now. The new swords are still unstable." Serafall runs up with a phoenix tear.

I glare at Trihexa and hold up my hand. My hand begins to glow in holy light. I my hand start to burn and I fire a large beam of holy light at it. It staggers back and stops its attack. Serafall opens the phoenix tear and drops it on me. I recover and then i hear it people talking from the other side.

"What heck was that?" sister says first. "Did he fire holy light? How can a devil use light?"

"It seems the secret will be revealed soon," Father Comments.

"What secret?" Sister questions him.

"I am devil that can use holy light," I explain as I stand up. "My use of holy light comes from a very specific reason." I close my eyes. Its now time to use it, I begin to step towards Trihexa. Red light starts to shine and engulf my body. "I am the Crimson devil who broke into heaven and stole power of heaven. I selfishly use the power for my own gain, my desire to destroy those who get in my path." The red light shines so intense.

The light fades away; I now stand there with only my dragon armor on my forearms and my legs in the form of boots. The rest of my armor is a combination of a leather appearance with chainmail. I hears gasps because on my back is twelve crimson red angel wings. Above my head is a crimson halo. "Crimson Archangel," I say.

I look back to see sister looking at mother questioningly. "What is going on mother?" sister demands.

"He is your twin brother," she tells her. "He simply was granted a gift." Sister isn't buying it.

"It goes beyond that mother," I tell her. "You may see the truth behind this gift." I turn back to Trihexa. I point my finger at it and shoot a crimson color holy light beam at it. It explodes on impact and covers it in holy flames. "Issei pay close attention. This form is ranks only slightly below your pseudo DxD form." I then fly into the air and fire more beams on Trihexa. It reacts my swiping at me. I fold my wings in and spin around its arm. I touch the arm and it explodes off.

I continue to fly around it firing beams at it. My beams are starting to have no affect on it now. I move back away from it and hold my arm up. Clouds form again in the sky. I point my finger at it and the lightning hits it. On impact it explodes, and ignites on fire. While it's regenerating, I land back near the leaders. I pick up the sword and Holy Aegis. "I am starting to understand why the hid you," Azazel comments.

"This is nothing," I explain to him. "This is about 10% of the forms true power. I can't use its full power; it's currently too unstable and would kill me instantly. I haven't even gone out fully even in this state. I can go full speed and not burn myself." The holy Aegis shrinks and I put it on my back. I move sword to my left hand. I hold out my right hand towards the other sword and it flies into my hand. I take a step forward and appear to the right of Trihexa. 3 heads and one its arms fall off then disappear.

"What is with that speed?" Odin asks.

"It's a speed only he can use when fighting with swords," Souji starts to explain. "Specifically, he can only use it awhile duel wielding and under certain conditions. Though it comes with a backlash, he would normal burn his arms due to reaching said speed. He is close to surpassing me soon."

Right as Trihexa regenerates, I cut off more of body. I land back away from it. I can feel the fatigue setting in. I am running out of time and I have pushed this form too much. I haven't even done what I needed to seal Trihexa. This form is not enough and its full power would kill me. I am breathing heavy. I was too busy thinking to see its next attack. I am sent flying back again and badly bleeding again. Another phoenix tear is used to heal me. "I am using up all the tears," I say and punch the ground. "I fully understand how Issei felt." I am staring at the ground. "Kronus looks like I have no choice."

"Are you sure?" he asks me. "You said you could only use that form once."

"I have no choice," I answer him. "I am out of time. Everyone I need 10 minutes." I look back and they nod. They charge forward and I sit down. I close my eyes and dive deep into my soul.

Part 3

"So you have come to me at last," a voice says to me. "I have been watching you. You are battling my old foe. Are you coming to accept who you are now?"

"Yes," I answer the voice. "I am no longer afraid of this power I hold. I fully accept who and what i am. I have a reason to fight. I have a reason to speak peace. I will use my power to protect those who can't protect themselves."

"Good," the voice continues. "With this acceptance you can use the proper chant without worry about killing yourself." I nod. "Though I suspect it will not be enough. So you must be here for that?"

"Yes I am deciding to use that form now," I say with determination. "I will seek a different power to fight what I have seen."

"Good move," the voice comments. "That rely on this form would have weakened your future self. The future can change since it is not set in stone." The voice turns into a figure and hold its hand out. "Shall we?"

"Yes," I say as we shake hands.

"Ironic my reincarnation is a devil," it comments. "At least he is a Gremary. I have always liked them. It's also a shame you didn't figure out how to control Trihexa, it would have been a useful weapon against them."

Part 4

A bright golden light surround my body and I can hear angels talking about. I open my eyes and look towards Trihexa. "One thing that I have been wondering for all these years," I say to everyone. "If heroes can be reincarnated then why cant God?"

"It can't be," Michael says. I smile.

"I am Cartil Gremary," I yell out. "I am the ironic Reincarnation of God." The light shines so bright it blind everyone. After the light fades away my appearance and voice have been altered. I now appear as God himself. I step passed everyone and walk up to Trihexa. I lift my arms and it is slide into many pieces. I touch the core and begin. "Be sealed away once again." Magic circles appear all around the pieces of Trihexa. A light shines bright and after awhile Trihexa disappears.

I turn and walk back to everyone. The run up to me and surround me. "Now crowd my brother," Sirzechs says and smiles.

"Mission finish," I say with a smile. "Oh no." I return to normal and feel intense pain. Wounds appear all over my body and I cough up blood. My vision goes blurry. I can hear the leaders and everyone on the other side panicking. I pass out.

Part 5

I wake up in a hospital bed. I sit up and look around. It's a different room then i am used to, there seems to be more special machines in this room. I was trying to figure out what happened but i don't remember anything after activating the God form. I hear the door open and suddenly i feel someone hugging me.

"Your awake," it sounds like sister. She is now crying. I look at her. "Everyone was worried and scared when we saw you lose that much blood. Hanalil had to take Ri out of the room."

"Blood?" I ask her.

"Yes you loss a lot of blood," brother says to me as he walks in. "It seem using that form of yours combined with using that many seals rebounded on you. It damaged you greatly and took a chunk of your life force."

"I did it?" i ask him and he nods. I smile. "I did it, I freed everyone."

"Our family is together once again," Father says as he and mother walk into the room. "I am proud of you son. I hope you are no to mad at us anymore."

"I am not mad," I tell him. "The past is the past, now we must look towards the future." Someone runs in and pushes sister away. I am hugged by this person. Wait I see the hair and it clicks. "Grayfia? This is not like you. Wait you are not dressed like a maid, but still."

"You brought him back to me," she explains to me. "This is why I am acting this way." She stands and smiles at me. "Your girls will be here soon. Ajuka and Shiva will always want to talk to you after." She walks out of the room.

"Though we leaders are back." brother starts to explain. "We will still be continuing our plan to hand everything over to your generation." I hold my hand up to stop him.

"If you are going to offer me a position I am will decline," I tell him. "I am not devil king material, i will though create an elite military team of this and next generation to deal with the upcoming threat in 30 years." I turn to sister. "Don't ask, you will be told soon enough. From this moment on Team AxA is formed and i will be leading it."

"Well it seems your girls are here," brother comments. "I hear running in the halls." Just then the door bursts open and i am quickly surrounded by all my girls who are crying. Ri climbs on to the bed and hugs me.

"You are not allowed to die," Nivana is the first to speak and it sounds like she is making a demand. She grabs my hand and places it on her stomach. My eyes light up. "Yes, we are finally having a child."

I turn to sister and smirk. "You may be older than me by 10 minutes but I am winning now," I say to her and she blushes. "What are you waiting for sis? You are the first wife, so seduce Issei." I laugh and she turns even redder. She turns away from me. I hear brother laughing. I am loved but there is still one thing brothering me. I look over to mother. I get a flash of what happened long ago.

Part 6

I am at Ajuka place, I brought along Vali. We are trying about the future.

"We need to deal with Hades and Indra before we can focus on planning for what's coming in 30 years," I state to everyone. "I suspect though even after we deal with those two, someone else will get in the way. The Egyptian gods and the gods in the Americas have been oddly silent. I fear Set and Anubis may be planning something."

"So my grandfather screwed our future and things are crazy even now," Vali comments.

"We need to deal with the current threats before we can even prepare for what Cartil has seen," Shiva comments to us. "Indra will need to be taken care of first. Hades is still an unknown and will not make his move until he is ready."

"What do you mean that Cartil has seen?" Vali questions Shiva.

"The main reason for my return is based on a vision I had," I start to explain to Vali. "It happened shortly after Trihexa was taken into that barrier. I saw the largest army I have ever seen. It plowed through the first line of defense and headed straight for the underworld. It destroyed Lilith in a matter of hours. The death count sky rocketed day by day on our side. Even after some of the other world changed to our side it wasn't enough. In the end even with Issei's ExE form it wasn't enough. A tide of destruction and death is what I saw."

"Now you have changed the course of the future," Vali comments. "The invasion will still happen but now you are giving us a chance. I do look forward to facing the strong people from that side."

"Just leave Indra and Hades to me," I tell them all. "You all have your reputation to keep. I however do not besides even if I did I don't care for sad politics."

"Though the tournament has been stalled again," Ajuka explains. "Rating games will be held in the mean time. People want to see Sairorg verse Cartil."

"Figures," I say with a sigh. "They want to see what I can do because of my name and they pick Sairorg. I am guessing it has something to do with what i did on my first appearance. One major probably with that my queen can't fight with us. If i am allowed i have a temporary replacement in mind though."

"I will see what I can do," Ajuka says to me.

"Well I need to head out now," I say to everyone. "There is a big party for me. Its nice to have my area open again." I wave as I leave.

Part 7

I am sitting at a table at the bar near the pool. I am watching everyone. The girls are talking to each other about children. Issei is talking to Sirzechs and Sairorg about the possible rating game match Sairorg might have against me. I feel a tug on my shirt. I look to see Ophis and Lilith stand there.

"You wanted to talk to us," Ophis says to me.

"If you don't mind I would like to talk you both somewhere you might like," I offer to them. "It will have some wonderful food as well." Ophis appear to be thinking about it. "I want to be a friend but truthfully there is something I need your help with."

"I will consider it," Ophis says to me and she leaves with Lilith. She is a very odd dragon. Tannin walks up to me this time.

"Just the dragon I was looking for," I comment. "What is this I hear about a spetre dragon egg?" he looks at me stunned.

"I am surprised it took you this long to as me about it," he says to me. "Well if you know about it then you already know its location. So what are actually asking me?"

"I am thinking about learning more about dragons," I state to him. "I at some point would like to create a pact with a few." I look at my right hand. "A debt must be repaid as well. Kronus, i am sorry. I hope you recover soon."

"I will see what i can do," Tannin says with what looks to be a smile. "You should enjoy the party more since it is for you."

"I am not use to this kind of thing," I explain to him. "I use to hate parties but maybe they will grow on my now." I notice Asia is walking over to Fafnir to give him some food. I glance over at Issei and he seems to be waiting for the same thing i am. We then hear it.

"Panties with food make the food better," Fafnir says. I get up and start walking to Fafnir; Issei has seen that and ran to grab Asia. He grabs her and takes her back to the group.

"It seems Asia's talking to did not click with you Fafnir," i say in a rage and begin chanting. "I am the Crimson devil who broke into heaven and stole power of heaven. I selfishly use the power for my own gain, my desire to destroy those who get in my path." With a flash of red light I change into the Crimson Archangel form. I reach Fafnir and glare at him. He begins to stand and i raise my arm up. He is instantly surrounded by chains and against the wall behind him.

"Please don't kill him," I hear Asia asking me while crying.

"You are a dragon king Fafnir," I begin to say. "You need to start acting like one. You are nothing but a pathetic dragon now. If i had the power I would revoke your title. I am surprised Issei hasn't killed you for the crap you put Asia through. No more Fafnir, you are no longer allowed around Asia until you snap back into your sense. If you dare come near Asia until then i will kill you and turn you into a sacred gear." I touch his head. "The pact with Asia is now broken and you will be leaving soon." I turn and walk away.

I walk up to Asia. "It seems awaken the god form has given him more abilities," i hear brother comment. I grab Asia's hands and look at her.

"Issei, you have great restraint," I say to him as he is behind Asia. "You have been through enough Asia. You do not need Fafnir. An aura engulfs Asia and my hands. "You are my family and family helps each other. I have upgraded your twilight healing. It has two new abilities, a barrier that will protect you and a new ability that I will let your growth awaken." I smile and step back.

"Thank you," she says to me.

"Quick question," Azazel walks up to me. "I have been meaning to ask you. Since you are the reincarnation of God, is there a reincarnation of the Great devil king?"

"Yes there is," I turn to him and say to him. "I know who it is but at this time her powers have not awakened." Everyone looks at me shocked.

"You have already met her?" brother asks me this time.

"Yes I have," I begin to explain. "She was going to be my queen before I met Nivana. She was unable to because of her father. Which is fine with me, Nivana is a better queen anyway." She runs up and hugs me. She kisses my cheek.

After that everything in the party returns to normal. I am back at the bar watching everyone. I had returned to my normal form after Fafnir disappeared. Serafall and brother walk up to me. Brother hands me an envelope. "Your recent actions have caused this," he says while pointing to the envelope. I open it and slowly pull out a piece of paper. I pause and stare after reading part of it.

"Promotion to Ultimate Class devil," I state in shock. "I never expected this but I am glad. Well I guess its time to find my last rook."

Part 8

I am at my lap and I am putting the last touches on two of my projects. "I understand what was missing now." I say to myself. "The special piece is finished. Akeno soon you will see your mother again." I grab a bottle from the table. "This will change everything in the underworld. I will need to have someone test it. I will ask Lady Phoenix."

Chapter 5 Author's notes, nothing major here. First arc is done.
