"Ophis-sama just deactivated the last bomb, but the building has become unstable and will probably collapse. Are all the civilians evacuated?" Ravel asked.
"Help!" A scream was heard near the building. When they turned around, they saw a devil trapped underneath the debris caused by the Khaos Brigade's previous attack.
"I will help." Koneko headed to the victim's direction and lifted the debris trapping him.
"All civilians have been evacuated from this area." Koneko told the group.
"Let's just hope that the rest can beat the Khaos Brigade." Gasper said.
Suddenly an explosion occurred in a building near where the civilians are running. Ophis looked outside to see a different building about to collapse.
"Gasper, use Forbidden Balor View."
"Yes Ophis-sama." Gasper did as he was told and was able to slow the building's collapse before it can hit the evacuating civilians.
"Apparently, the Khaos Brigade came up with a back up plan should one building fail to kill the civilians. We better check every building near the area and disarm the bombs we might find." Tomoe suggested.
"Are you going to be okay on your own?" Ravel asked Gasper.
"Ophis is still with me so I am not alone." Gasper finally smiles with determination, something that is really rare for others to see.
With Gasper preoccupied, the rest head into all of the buildings nearby to check for bombs and disarm them.
As with Issei and Saji…
"Just how much harder is it to restrain Quetzalcoatl when you don't have the element of surprise?" Saji complains.
"Much harder. I cannot even touch him with this speed, even in my True Queen Mode." Issei told Saji.
"Then I will slow him down." Saji uses another one of Vritra's abilities, creating a field around Quetzalcoatl, trapping him.
"Delete Field will not only trap him, but absorbs his power as well. I don't know how long it will hold so you better come up with something that can beat him Hyoudou."
"Thanks Saji." Issei aims Ascalon at Quetzalcoatl, but before he can even fire, Quetzalcoatl launches a huge blast of energy from his mouth and breaks free from Vritra's domain.
"I can't trap him for even a few seconds. We have to weaken him somehow."
"The heavily boosted power of Ascalon should be able to take out Quetzalcoatl, but his speed is the problem. In order for me to make a hit, we've got to slow it down somehow."
An idea comes out of Saji's head. "Hyoudou, maybe I can restrain Quetzalcoatl for a longer amount of time, but I am going to need you to transfer some of Ddraig's power to me and boost it."
"How much do you need?"
"Until I can find myself able to trap the God long enough for you to hit." Just as Saji finished talking, Quetzalcoatl launches another attack towards Issei and Saji, forcing both of them to move quickly form the area.
"Hyoudou, do it now!"
[Boost! Boost! Boost! Boost! Boost! Boost! Boost! Boost! Boost! Boost!]
Issei boosted Ddraig's power 10 times and transfers it to Saji, who was both impressed and frightened at the same time.
"Wow. So this is the power of the Heavenly Dragon. Very scary."
"Saji, slow Quetzalcoatl down!" Issei reminded him.
Saji then uses Shadow Prison again to trap the giant Serpent God. Like Saji predicted, he was able to hold Quetzalcoatl longer, but was unable to hold him long enough for Issei to make his move, as the Serpent God was able to gather more of his strength and breaks free from his restraints.
"Not enough Hyoudou!"
Issei then continues to boost Ddraig's power as he and Saji continue to evade Quetzalcoatl's attack.
With Rias, Shinra, and the two assailants that are fighting…
"Jeez, you are strong for an average Queen." The 2nd assailant said as his blade continues to meet with Shinra's naginata.
"You've made it sound like being a Queen is weak. Let me show how skilled I really am." Shinra deflects the 2nd assailant's attempted strike and soon starts gaining the upper hand, putting her opponent on the defensive.
As Rias battles the assailant leader, the latter uses his high speed to his advantage as Rias continues using the Power of Destruction in hopes to hit him.
"Face it. I have already known about your clan's power. If that is all you have, then it will be easy for me to avoid and strike you."
Rias smiles at her opponent. "Then why don't you come at me?"
Believing that Rias is bluffing with her smile, the assailant charges at Rias, but as soon as his foot touches the building, the roof collapses, catching him off-guard.
"What the?" The assailant looks up at Rias.
"I knew you were too busy focusing on my attack and while you were doing that, I have been casting magic on the building to weakened the roof and the floors of the building. Now let's try this again. Shinra, you might want to jump to the next building."
"Understood." Shinra jumps out of the way, causing confusion for the 2nd assailant, who is unaware of Rias' plan.
Rias unleashes the Power of Destruction to the still surprised assailant leader, forcing the 2nd assailant to get out of the way after realizing her plan. At the last second, the assailant gets up and begins running as Rias' attack destroyed the entire building, creating a huge amount of rubble and dust.
As Shinra walks by the destroyed building, the 2nd assailant suddenly emerges from the debris and strikes Shinra with his fist, kocking her back a long distance.
"Forget about holding back! I am going to kill you!" The 2nd assailant then launches a powerful spell out of anger.
Shinra then activates her Sacred Gear, Mirror Alice, forming a mirror in front of her. The assailant's attack destroyed the mirror, but unbeknownst to him, his attack was reflected with double the damage, killing him and ending Rias' and Shinra's battle with the assailants.
Back in the Dark Matter Dimension…
"What do you think she is doing?" One of the hooded figures asked, as Serafall remains motionless with her eyes closed.
"I don't know. Doesn't seem like she is attacking, but I do sense magic being channeled inside of her body." Another answered.
"Whatever she is doing, anything she unleashes would disappear anyway."
"I don't think that would be what she is planning since she already knows her attacks are useless in this dimension."
"Then what is she planning? There is no telling what a Maou can do."
As the five hooded figures continue to guess what Serafall is planning, they are suddenly losing their grip they have to keep her in the dimension.
"What is going on here? This isn't supposed to happen!"
"It's the Maou! Look at what she is doing!" The five figures turn their attention to Serafall as her magic slowly becomes visible.
"We have to stop her before she breaks free from our grip!" The figures summon the shadows to attack Serafall, but the magic accumulated in her body begins to surround her as aura, protecting her from the unseen attacks.
Serafall unleashes a pulse of magic, which weakens their grip of her even further. Realizing that she knows she was being held by their magic and has found a way out, four of the five hooded figures attempted to attack.
"Got you."
Serafall actually laid a trap for them and as soon as they were within range, she unleashes all of her magic she has gathered and launches another powerful field of ice towards them. They became frozen in an instant, unable to hold the powerful spell. Free from their grip, Serafall returns back to the Underworld exhausted.
"That should take care of that."
Before Serafall can relax, however, she was hit from behind by a spell, knocking her back. The last of the figures was standing right behind her.
"It seems like that strategy caused you to reach your limit. I still have plenty. I am going to enjoy this as revenge for my allies."
Serafall attempts to stand up, but unable to react fast enough, she keeps getting knocked back by her opponent.
"Surrender and I will make sure your death is quick and painless."
"My friends are all risking their lives to fight. I won't back down." Serafall responded.
"What are you going to do if you are unable to fight back? If spells won't work, then I will have fun messing you up with my fist." Her opponent removes his hood, revealing himself as a young man showing a sadistic look on his face.
The figure picks Serafall up and punches her on the head, knocking her back, resulting in a bleeding forehead.
"Are you afraid to die?" The figure asked.
"No." Serafall gets back up, but gets knocked down again.
"With the way you are now, I don't even have to waste much of my magic on you." Serafall opens her eyes, only to see another fist coming.
The next scene switches back to Issei's and Saji's battle against Quetzalcoatl.
[Boost! Boost! Boost! Boost! Boost!]
[Partner, that's enough. Giving Saji any more will make it harder for him to contain it.]
"Right. Saji, this is as much as I can give you."
[Transfer!]
"Thanks Hyoudou! This might be enough to defeat Quetzalcoatl." Saji then charges towards Quetzalcoatl.
"Hyoudou, you ready with Ascalon?"
"Yes. I just need it to hit Quetzalcoatl." Issei boosts Ascalon's power for good measure as Saji uses Shadow Prison for the third time.
Quetzalcoatl was successfully trapped this time, allowing Issei to charge the Serpent God head on.
"You better hurry up Hyoudou! I don't know how long Shadow Prison will last!"
"I know! This is it!" Issei charges at Quetzalcoatl at high speed.
With Quetzalcoatl defenseless, Issei punches the Serpent God at full force with his Ascalon powered fist, knocking Quetzalcoatl unconscious. Dark aura suddenly surrounds Quetzalcoatl only for it to disappear.
"Think we freed him?" Issei asked.
[I no longer sense the negative energy the Khaos Brigade put into him with Samael's blood. He shouldn't be under Khaos Brigade's control any longer.]
"Good, because I don't think I could beat him if he really was our enemy."
With the battle over, the 1st assailant was shown to survive Rias' attack, but not without injuries as the left side of his head is bleeding over his eye.
"Great. How am I going to report to Hades that our plan failed again? This is not going to end well for others since Quetzalcoatl has been freed."
As soon as he stops to take a break, he saw Millicas heading over to Issei's direction.
"Why hello there." The assailant makes a sinister smile as Millicas anxiously waits for him to make his move.
With the battle against the Serpent God finished, the figure attacking Serafall becomes more frustrated than ever as the tables are turned on them.
"We might not have won the battle, but the war will still continue. I just love watching you Devils die. Before I run, it will be you who I kill." The figure begins casting another spell as he stares at the badly beaten and bloodied Serafall, who can only stare at the face of death as his spell grows bigger."
"I am sorry everyone." Serafall tearfully closed her eyes.
Before the figure could launch his attack, a shot of highly pressurized water knocks him back a long distance. As he lies unconscious, Sona approaches him in a hostile manner.
"How dare you do this to my sister!"
"So-tan…" Serafall struggles to get up.
Seeing her older sister badly beaten and nearly falling unconscious, Sona rushes to her.
"Onee-sama. It's okay. Come on, let's go find Asia-san."
"Thank you." Serafall said softly as she loses consciousness.
"It saddens me to see you like this Onee-sama. I better stop the bleeding first." Sona said to her unconscious sister as she takes out a sheet and wraps it around her head.
As with Kina, Xenovia, and Irina, their battle was won thanks to the back up of Bennia, yura, and Garou.
Kiba wipes off the sweat building up on his forehead. "That was a tough battle. I wonder how Buchou and the others are doing?"
"They probably succeeded since they also received help from Kaichou's peerage." Xenovia said.
"Well then, should we go meet them?" Irina becomes excited.
"Let's go find them. Thanks for the help." Kiba waves to Bennia, Garou, and Yura, who smiles at them in response.
The battle with the Stray Magicians ended with the victory of Akeno, Rossweisse, and Sylphi, thanks to some assistance from Momo and Reya, who were able to penetrate the Magicians' defenses with their combined strength.
"Ara-ara. I think I overdid it again." Akeno shows a sadistic smile further scaring Momo and Reya.
"I think we should continue by assisting the other groups. What do you all think?" Sylphi asked.
"Chances of victory will increase with assistance so I agree." Rossweisse said, causing all to head further down the battlefield.
The result of the civilian evacuation with Ravel, Koneko, Gasper, Ophis, Tomoe, and Ruruko was also a success, bringing the Khaos Brigade's hopes for high casualties to a halt.
"Gasper, you can deactivate your ability now. All the bombs are disarmed and no civilians in sight."
"Thanks Ophis-sama." Gasper closes his eyes and returns his eyesight back to normal.
"MILLICAS!" Issei's scream was heard and they all rushed to his location.
When the group rushed to his location, they saw the other groups have already made it, but what worries them the most is what is standing in front of them. The surviving assailant was able to grab Millicus and holds him hostage, but is unable to get away as he is surrounded by Rias' and Sona' peerage.
"You all better stay back or I will stab this blade filled with light into this kid's throat."
They all avoid getting near the assailant as a result, but Issei had an idea. "Hey lackey!"
"Don't you call me a lackey! I was the one in charge of this entire thing and I will not lose to a bunch of brats!"
"Sorry, but the blade looks fake. You won't even hurt a fly with that."
"Ise, what are you doing?" Rias becomes worried over what Issei is planning.
The assailant points the blade at Issei. "You better watch it. This blade really has light in it and I will cut all of you up with it after I am done with him."
"Millicas, break free now!" Issei screamed.
Seeing the blade pointed away from him, Millicas elbows the assailant's gut and knocks him away with a spell without having to use the Power of Destruction. Everyone was impressed with the young boy acting in self-defense.
"Let's see how you like it once Tou-sama gets here." Millicas smiles at Issei, who gave him the chance to escape.
Sirzechs arrives soon after, but was shocked to see that his son is there. "Millicas, what are you doing here?"
"I wanted to help Tou-sama. Take a look at what I've done to a member of the Khaos Brigade." Millicas pointed at the unconscious assailant, causing Sirzechs.
"I am mad you disobeyed my order not to get involved, but at the same time proud of you. You have shown to be able to beat more powerful opponent like members of the Khaos Brigade, but please don't do this to me next time. You will be able to go on your own once you are old enough."
"I understand Tou-sama."
Just as everybody is about to relax, they saw Sona carrying the injured and unconscious Serafall. Seeing Serafall in this state, Issei rushes to see if she is okay with everyone following behind.
"What happened to her?" Issei asked.
"She was ambushed and badly beaten. I am hoping to get Asia-san to heal her."
"Yes Kaichou." Asia uses Twilight Healing and is able to close all of her wounds, but Serafall isn't waking up.
"How did this happen to my sister?" Sona asked as she continues to stare at Serafall's body out of worry.
"I was with Serafall-sama when five members of the Khaos Brigade attacked us. She told me to go look for Ise-niisama so I didn't see what they did to her. They must be very powerful to have done this to a Maou. Are they still there?"
"I only saw one when I arrived to the battlefield. Onee-sama must have been able to kill four of them, but reached her limit on the fifth one. I saw her badly beaten so I came as fast as I could and stopped him."
Issei, who is still affected by the sight of Serafall's injuries prior to her healing, moves closer by her side. "She is going to be okay, right?"
"Yes Ise-san. She had lost so much blood when I was healing her, but she will be fine after some rest." Issei becomes relieved after hearing Asia, but still feels guilty for Serafall being in this state.
"You are thinking that it is your fault that Onee-sama is like this, aren't you Hyoudou-kun?"
"Yes. Maybe is I had Serafall and Millicas come with me, this probably wouldn't have happened to her."
"You had your own battle to deal with Hyoudou-kun. I don't blame you for what happened and neither does Onee-sama. The Khaos Brigade is the one we should blame for doing this."
"Even I don't know why I blame myself Sona-kaichou. Maybe because it just hurts seeing her like this."
"I think you are just afraid of losing her. I was the same when I first saw her like this, but she is my sister so I know she is stronger than what she is showing. We just have to believe in her."
"You are right. If she is trying to be strong then so will I. Come on Levi-chan, you can make it."
Sona smiled seeing Issei worrying for her sister. "You seem to care a lot for Onee-sama to act like her condition is life-threatening."
"W-well that's because this was the closest that I have ever felt to losing someone after Asia. It will hurt a lot if I lose Levi-chan."
"You really are that close to her. I was skeptical at first, but seeing how much you two are attached to each other, I have grown to be more supportive of Onee-sama's stay at your house. Ise-kun, you truly are a good person."
Issei blushed hearing Sona complimenting him with her honest feelings, causing anger from Rias and most of her peerage and Saji.
"Since when do you call Ise by his name?" Rias asked Sona.
"I told Ise-kun that I would call him by his name in private, but that no longer matters now."
"Of course it matters! Don't tell me that you've become attracted to Ise!"
Sona blushed upon hearing Rias' accusation. "Don't accuse me of that! I am just saying I like that he cares for my family!"
As the two girls argue, Serafall starts to wake up, which Issei takes notice. "Ise-kun? What happened? Is the battle over?"
Before answering Serafall's question, Issei hugs her out of relief, causing her to blush. "Yes, the battle is over. I am so glad you are okay Levi-chan."
Issei then starts having tears in his eyes. Seeing how much Issei truly cares for her, Serafall smiles and embraces him in return.
"I am glad that you are okay as well."
Hearing Rias' and Sona's argument, the Serafall and Issei turn their attention to the two girls and started laughing at them.
"They really get along well don't they Ise-kun?"
"You can never be closer as friends like them Levi-chan."
"Hey Ise-kun, after we relax a little, do you want to go on a date with me?"
Issei smiles at Serafall. "Of course. Will the day after tomorrow be okay?"
"Any day that we don't have school." Serafall giggles.
With the battle over, everyone begins to relax, but, unbeknownst to them, a messenger of Hades is reporting the result of the attack to him in the Realm of the Dead.
"The attack on the Underworld was unsuccessful Hades-sama. It appears as though everyone sent has been killed or captured by Underworld authorities."
"Unacceptable. Not once, but twice did the Khaos Brigade failed to eliminate those unnecessary beings."
Hades stood up and begins walking forward to his messenger, giving off a creepy aura surrounding his body.
"If the Khaos Brigade is so incompetent, then I will take matters into my own hands, starting with the meddlesome Sekiryuutei. Once the time comes, he better watch out."
The Hades arc should be the last arc of this fanfic with little inspiration from the remake of Clash of the Titans film. Look forward to it.
