Chapter 6: Killing the past

*Mountain of Flower and Fruit*

Bikou loved his kingdom. That was a fact. He knew he wasn't as half good king as his father or his grandfather before him, but in his eyes he did a good job. Watching from the roof of his palace, he saw how people were, and he was pleased.

The palace was surrounded by a river and in some kilometers they were all the villages in a circle like way. There still was distance between them. The reason why the villages were arranged like that was security matters. If a village was attacked, then the guards at the palace and the warriors of the two neighbor villages go to aid. It only takes 5 minutes for backup to arrive.

And seeing how people was interacting and smiling, made him smile. But all this peace that he was having was interrupted by a loud explosion and a red light over the horizon. His eyebrow twitched, because he knew the cause of the explosion.

"Bikou-sama!" A guard said appearing behind him. "Yeah, I know already," Bikou said annoyed "Don't worry I'll handle it." "Are you sure?" The guard asked in worry "Yeah, you go to tell the others to calm the people. I already know what cause this anyway."

The guard nodded and left confused to fulfill his order and Bikou left to the epicenter of the explosion. 'I just hope that the damage isn't too big.' The monkey king thought in his way to the area.

*Somewhere in the Mountain of Flower and Fruit*

Issei and Vali where resting in the only remaining untouched tree, of what was a forest full of them moments ago. The reason they went to do one of their spars in this place was simple, the one assigned to them was way too small for their taste. And it was the basement of the castle and it was of 55.000 squere feet.

In the tree Issei and Vali were chatting over their training. "You're improving Hyoudu." Vali praise him "You weren't bad neither Vali, I feel the gap between us becoming smaller." Issei said with a smile "Maybe, but there is still a gap." Vali said with a smile and got some chuckles from Issei.

After some moments of comfortable silence, Vali asked "Why do you trust us so much?" Issei didn't look at him, instead just looked to the horizon with a smile on his face "Because you guys help me when I needed help to escape from my past. Everything bad that happened to me was because I trusted too much. I trusted Yumma or Raynare, and that got me killed. And I trusted Rias, just for be used like a toy. I'm not going to lie; at first I had my doubts about you guys too. But after so much time, I finally feel at home with people that understand me."

Vali processed all this and asked "So that makes us friends?" Issei didn't look at him and answered "No," he made a pause and said "We're brothers."

Vali took the confession and smiled at him "Yeah, you're right. But I would be the favorite between us." Vali joked and after some laughs they keep on chatting until someone interrupted them.

"WHAT THE HELL WHERE YOU TWO IDIOTS THINKING!"

That was a really piss Bikou, which was with a tic mark on his forehead, and one fist up in threatening manner. The answer from the both asked was "Training." They both say at the same time.

"Training!?" Bikou asked/screamed "How the hell destroying a forest is consider training!?" Bikou said and Issei and Vali looked around to see the environment. After some seconds of this Vali said "I don't see a forest." At the answer Bikou wanted to smash his head against something. "It is because it is destroyed!" Bikou exclaimed "Then you should take more care of your kingdom." Issei deadpanned him. Now Bikou wanted to smash Issei head against his staff.

"Anyway we need to go now. I have something to say to the whole team." Vali said while standing up, Issei nodded and follow suit. Bikou just stand there for some seconds with a twitching eyebrow and screamed "Don't you think this is over yet!" "Hai,Hai." Was Issei lazy answer. After that they left to the castle.

*Main Hall of the Palace*

In the main hall, there was the Vali team, talking about their next move. "So what is this meeting about? ~Nya~" Kuroka asked "About our plan." Vali stated. "Which is?" Arthur asked "As you already know, our objective is destroy the Fusi Sunt." Vali started "Yeah, you already told us that yesterday." Issei said. "Yes, but to do anything first we need information." Vali answered.

"What kind of information?" Le Fay asked "Information about the Hero Faction moves. Right?" Bikou said "Right. Before we do anything we need to do two things. First, secure the key. Even though it is already in our main base, if someone break in he or she shouldn't have a big problem finding and taking it. So when we get back to the base we are going to take all the precautions, to avoid losing the key. Second, information about every move that the Hero Faction have done. There we can find a pattern in their moves and formulate a plan."

There was a moment of silence or everyone to take the plan until Kuroka asked "And from where do we take that kind of information? ~Nya~" "Probably from a top fallen angel of the grigori, or an important devil." Arthur said and Issei continued "If that's the case, it should be Azazel-sensei or the Gremo…" Issei didn't finish knowing that he might meet his old group again really soon.

"Yes. Tomorrow we're going to attack the Gremory Manor, to try to get as much information as we can of the Hero Faction." Vali confirmed and turned to Issei "Are you okay with this Hyoudu?" Issei just smiled at him and said "Yeah! If I could confront them once before, I can do it twice. Besides, what are the chances that Rias and the others are there?" Issei said with a smile which Vali smiled back at him.

"Very well, now everybody go to rest we have a big day tomorrow." Vali concluded and everybody left for the exception of Vali and Arthur. "Tell me Vali-san; you choose to attack the devils first to help Issei-san recover from their betrayal towards him?" Arthur asked and Vali let out a sight "Yes, I can still see through his mask, and I see he still have problems about it. I want to help him." "Like a comrade or a friend?" Arthur asked again "Neither." Vali answered and Arthur raised a brow "Like a brother." Vali ended with a smile. Arthur smiled at the answer and said "Good by me. Good night Vali-san." Then both left to their rooms.

*Issei's room*

Issei was on his bed awake thinking about tomorrow. It had been only one week since he last saw them, and now he might just see them again.

['Relax partner.'] Ddraig voice said inside of Issei mind

'I know, it's only that it is still too quick for this.'

['It might be, but remember, you have now people that support you. Especially Kuroka.']

"Ise-kun?"

['Talking about the devil']

There at the door steps, it was Kuroka in a black nigh robe with red borders. "Having problems to sleep? ~Nya~" Kuroka asked getting closer. "Nah. Just thinking a little bit." Issei said. "About them?" She asked already knowing the answer.

"Yeah. Even though I did great last time when I last saw them, I was about to hug them or destroy them. Besides this time we're going to their house this time. So this time will be more dangerous if Sirzechs is there." Issei explained and Kuroka nodded, knowing how badly a fight against the stronger devil might turn out.

"Don't worry. ~Nya~ We're strong. Every single one of us. Besides Vali somehow always have a plan that always take us out alive, either the mission was a success or if it failed. And if Rias tries to take you again, I'll show her that you are and never will be her toy again." Kuroka stated making Issei feel better. "Besides you can't leave until you gave me my sixteen kitties Ise-kun. ~Nya~" She said and Issei eyes widen "Weren't twelve last time?" "Yep, but it increased as payment for comforting you. ~Nya~" She answered happily. Issei only sighed and patted gently her head "Fine. Good night Neko-hime." And fell asleep and Kuroka follow through with him.

*Next morning, outsides of the Gremory Manor*

"So what's the plan?" Bikou asked "When you shut up I can explain." Vali answered. After some mumbles of Bikou he became silent and Vali continued "Okay, this is the plan. Arthur and Le Fay will stay here in the escape route with the portal when we need to leave. Also you two will warn us if some kind of reinforcement is coming." Vali commanded to the brothers which nodded and turned to Bikou, Kuroka and Issei "You three will get the information. It should be at the storage vault located in the basement of the mansion. Watch out though, there was a rumor that Azazel gave some of his experiments to Sirzechs and he puts them in there. So be careful." Vali told them and they nodded "And I will make the distraction for you to come in." Vali said "And what would be this distraction be Vali-sama?" Le Fay asked making Vali grin like a mad man "I'll fight Sirzechs." He stated making everyone wide their eyes "What?" Issei asked in worry "What you heard Hyoudu, I'll fight Sirzechs in his office keeping the bigger threat there, at the same time attracting most of the servants to that room to try to help their master." Vali explained.

"There are different signatures more than the servants Vali-san." Arthur said gaining everyone attention "I can sense Garfia in the office with Sirzechs and I can also feel the same amount of power coming from another one leaving the room." "Azazel probably." Vali interrupted "Yes and another seven different signatures in the main room." "Rias and her peerage." Issei said and everyone attention changed to him. Noticing this he decided to calm them down "Don't worry I'll be fine. Besides I got Bikou and Kuroka to back me up." Issei said with a smile. "Very well. When the alarm starts you three get in the building." Vali ordered and left with his sacred gear activated.

*Main room Gremory Manor*

Rias and her peerage were in the main room of the Gremory mansion. The reason they were called was because, they were assigned to protect the mansion from any type of attack. Rias protested saying they should be looking for Issei instead but her brother convinced her saying that Issei might appear if they attacked the manor.

Their thoughts were interrupted when a loud sound and the alarm saying that Sirzechs was being attacked. The peerage was about to move, when Koneko just looked to another part of the mansion. "Something wrong Koneko-chan?" Asia asked her. Koneko didn't say anything for a seconds "Nee-san and…" She made a pause "Issei-senpai."

At that everyone eyes widen and Rias ordered "Koneko guide me to where he is, and the rest of you go help Oni-sama."

"Hai!" was the response of everyone except Kiba

"I want to go too." He said in a serious voice. Rias nodded and the group split in different directions.

*Sirzechs office*

Behind the desk was Sirzechs Lucifer standing up and behind him, his wife and head maid Garfia, both glaring at the man in front of them.

It was Vali, sacred gear activated looking at the both of them arrogantly. The door was locked and the room was sealed for no one to leave or enter unless Vali or Arthur say so.

"What do you want Vali" The Maou asked dangerously "Two things really, First I would like some information about the Hero Brigade." Vali answered casually "And if I don't give you that?" Sirzechs asked again narrowing his eyes and making Vali smirk "Well, that would lead us to the second thing I want; kick your ass." Vali said confident.

Sirzechs only created a destruction ball on his hand and say "I'm sorry, but you can't have neither of those things. In change, you will receive death by my hands." At the same time Garfia created a magic circle to help her king if needed.

[VANISHING DRAGON BALANCE BREAKER]

Was heard and Vali was inside his armor in a fighting stance.

['Vali, this two are the two of the stronger devils alive. Prepare for this.] Albion warned.

'Don't worry, I came prepared since we left'

And then Vali charged, starting the fight of his life.

*Gremory Manor Halls*

"So where is this again?" The group of Issei, Kuroka and Bikou have been looking for the room for half and a hour now and they still don't find it. "Don't ask us, you have been here before, you should know." Bikou answered frustrated "But you studied the map." Issei countered "You too should have studied the map!" "Shut up both of you." Kuroka said frustrated "You two will call the attention of guards or worst." She wasn't using her ~Nya~. Bikou was about to say something when a voice ahead interrupted them "Need help with something?"

The voice came from Azazel who was leaning against a wall "Azazel-sensei." Issei said "Long time no see, kid." Azazel wave with a smirk getting of the wall.

"The leader of the Grigori." Bikou said while getting his staff ready for battle. Kuroka getting ready too. "Relax, relax, I didn't come for a fight. I came to help you." Azazel explained. "Why?" Issei asked and Azazel let out a sight. "Look Issei; I know what Rias did to you, and you are in all your right to do this. While you and your new friends don't attack anything related to the Grigori, you have my support." Azazel said with a small smile. "Why?" Issei asked again making Azazel take a more serious look "Because you are like a son too me." Azazel clarify making Issei and his group smile.

Azazel regaining his usual smirk said "Very well, now follow me." Then he left being follow by the trio.

*Gremory's storage room*

"So here we are." Azazel said while entering the storage room. It was a big hall with some papers that they deduce that was documents or paperwork, and some strange objects. When they were about to ask what were those objects Azazel said "Don't touch anything, those objects are experiments of mine that I gave to Sirzechs." "Why would you do that? ~Nya~" Kuroka asked.

Azazel chuckled before answering "You see, too keep a friendly relationship. He gives me stuff that he thinks I care about, and I give him things that I might think he cares about." Azazel answered. "And what if, I don't know, he decides to attack you with this?" Bikou asked "He can't. All of this experiments are failures." Azazel answered with a smirk.

"What do you mean sensei?" Issei asked. "All of this experiments have an error that make them extremely dangerous to the user of it. Hell, you can't even fix them to create a better version." At the answer they nodded and continue.

In the way to the files, Bikou accidentally, hit one of the failed experiments with his staff making it shake and glow making Azazel gain a panicked look. "You stupid monkey! You know what you just did!?" "No…" Bikou smart answer was. "That was a nightmare machine, it makes you see your worst nightmares and others will see them too!" Azazel explained making the others panic. Seeing the reaction Azazel tried to calm them down "Don't worry I got a device to counter the machine. Remember; do not fall to the illusions!" Azazel screamed before all turned pitch black.

*?*

The first thing that Issei noticed was the darkness. The whole room was made out of it. The second thing was noticing that he could see both Kuroka and Bikou like if it was with daylight, and by the looks of Kuroka towards Bikou he knew that they can see each other too.

"Bikou! Look what you did!" Kuroka screamed. She was pissed. "I'm sorry. It was an accident." Bikou tried to apologize but failed "An accident that might kill us!" Kuroka continued. Issei was about to say something when a voice behind him called.

"Long time without seeing you Ise-kun."

*Gremory Manor Halls*

Rias, Kiba and Koneko where running through the halls of the mansion when Koneko smelled someone else "Azazel-sensei is there too." Rias frowned "For his own good I hope he doesn't do anything to my Issei." Then the trio start running faster.

* Sirzechs Office*

Vali managed to dodge other of Garfia magic shots but because of this he was hit by one of Sirzechs destruction ball in the chest area, throwing him against the wall, and destroying part of his armor in the chest area.

['Vali, I feel that Ddraig user is in some illusion that might cause trouble.'] Albion warned and Vali smirked under his helmet.

'Don't worry about him. I know him long enough to know that he can get out of this situation.'

"Feeling like giving up Vali?" Sirzechs asked standing in the same spot that he started the fight, unscratched. Then Vali got up "No way. We're just getting started." Vali stated and charged once again.

*?*

Issei looked back and saw Raynare in her fallen angel bra and thong. She smirked in a seductive way and said "Did you miss me?" "Raynare…" Issei growl came. "I'm your worst nightmare Ise-kun. Oh and I see you brought some friends." She said pointing at Kuroka and Bikou who appeared at the sides of Issei, both ready to fight and Issei activated his sacred gear.

"Oi, Issei; who is the S&M chick?" Bikou asked trying to get under the skin of Raynare "Raynare, the one of Ise-kun's nightmares, right? ~Nya~" Kuroka said and Raynare chuckled. "Oh, you have dreams about me Ise-kun? That's so sweet from you. Now, let me show you yours friends nightmares." She said and her smirk became evil looking and with two quick claps from her hands the darkness became a medical room.

"This place…" Kuroka said with shock and fear on her face. When Issei was about to ask what is wrong with this place a scream behind the door called their attention. Before anyone could react Kuroka sprinted towards the door and when she opened she fell on her knees and muttered loud enough to hear "Shirone…"

Behind the door was Koneko tied to a bed being experimented by one man who was dressed like a doctor only that his white coat had blood on it, and being watched by another more fancy looking man.

"How are the test doing doctor?" The fancy man asked. "Really great sir, she is showing even more promise that her sister, but there is a chance that she might not survive the procedure." The doctor answered "I don't care. If she dies, we will look for another test subject." The fancy looking man said and the doctor nodded and continued his job making Koneko scream in pain. Just when Kuroka jumped to save her sister the room disappeared coming back into the darkness.

When the darkness was all that was left she felt on her knees muttering the name of her sister. "You bitch!" Bikou screamed and charged but Raynare dodged the strike and the darkness changed into a burning village with a lot of corpses around. Bikou realized that this was one of the villages of his kingdom and fell to his knees staring at the ground with wide eyes, with a shocked look.

Raynare got close to Issei and hugged him. "Now, Ise-kun; How much will it cost me to break you like your two friends?" But Issei just get off her grasp and said "A lot. Because it doesn't matter how much you try, I won't break again. besides it doesn't matter what you do, I will help my friends. If someone close to Kuroka is suffering, I'll save her!" Issei proclaimed and Kuroka looked at him "And if the kingdom of Bikou is burning, I'll will turn it off and help him kick the ass of the responsible of it!" This time Bikou looked at him "It doesn't matter what happens, I will help them!" Now Kuroka and Bikou stand up with smiles on their faces. "Yeah! All of this is an illusion anyways!" Bikou screamed with his staff at Raynare "Now you're done Fallen-Chan. ~Nya~" Kuroka said. Raynare face was one of panic now "Now…" Issei began and from his gauntlet has heard [BOOST][BOOST][BOOST] "Disappear!" and Issei punched her on the face . Raynare went flying but Issei felt he hit something else, and then the darkness disappear.

*Gremory's storage room*

When Issei looked at what he hit, he noticed that he hit the nightmare machine. "So you guys are out of it. Huh." That was Azazel with some weird golden goggles. "Ehh, Azazel-sensei, what are those?" Issei asked pointing at his goggles. "This?" Azazel asked taking them off "Are a special goggles that are design to eliminate the effects of the nightmare machine." At the explanation Bikou exploded "Then why didn't you destroy the machine!" But Azazel just wave him off "I knew you guys could handle it. Besides, I took that time to find these." He said waving the some papers "Those are…" "Yes, the Hero Faction information, all yours." He finished with a smirk. Then Issei took the papers and run out of the room with Bikou and Kuroka following "Thanks Azazel-sensei!" Azazel just waved a little and said "I'll catch up later."

*Gremory Manor Halls*

Issei, Kuroka and Bikou were running towards Sirzechs office when they heard behind them "Issei!" They look behind them without stop running to see Rias, Koneko and Kiba behind them with smiles "Crap, what do we do?" Bikou asked with a frown, he wasn't in mood for a fight "Maybe this time I should just kill her? ~Nya~" Kuroka asked with a way too sweet smile. "No, we don't have time for this. Just run faster." Issei said and they do as he ordered. "Issei wait!" Rias screamed but they didn't even answer just kept going faster and then she start going faster which she copied and then her other two servants too, trying to catch up Issei.

*Sirzechs office*

There was a beat up Vali, who was barely standing, with parts of his armor like left arm, chest area, lower right leg and one quarter of his helmet destroyed.

Sirzechs was preparing his final attack when something he didn't expect happened.

Issei in his Balance Breaker armor broke into his office and tackle Vali out of it by the same wall that Vali entered.

Then Koneko older sister and the monkey king enter and followed Issei.

Then his sister, her knight Kiba and Koneko enter to follow Issei.

Then the door opened revealing the rest of Rias peerage with stunt faces seeing nothing in the room.

After getting back from his surprise he ordered Rias peerage to go after them. After they left Sirzechs just sat down with a frown knowing how this was going to end.

They escaped.

*With Issei, Vali, Bikou, Kuroka, Arthur and Le Fay*

They were the whole group in the magic circle ready to get out of there. Then Issei turned to Vali who was holding his arm, without his balance breaker armor. "He really beat you up back there." Issei said smiling at his friend "Shut up Hyoudu, you didn't battle a Maou." Was Vali answer "It was your decision to do that." Issei said and Vali just huffed and they heard Rias scream "Issei!" But when she got to the magic circle, they already left leaving a crying Rias. "Issei…" she muttered.

*Vali team base*

When they arrived at the base Vali collapsed into the floor. With help of Bikou he got back up. "Mission was a success." He started "Tomorrow we will make the plan to get the Fusi Sunt, now go and rest." "Need help to go to your room Vali-san?" Arthur asked "Don't worry, I can move to there."

Arthur nodded and everybody left to their respective room. And in Kuroka case, to Issei's room.

*Gremory Manor Outsides*

There was still Rias crying with Asia trying to calm her down with no success. Also there was Sirzechs glaring at the ground where they escaped.

"This was a failure." He said to himself and only one person listened.

"You can say that."

That was Azazel with a frown. Or pretending to have one. He didn't wanted to fight right now.

"Where were you?" Was Rias question making Azazel change into a smirk "I tried, believe me I did. But the kid and his friends are strong." This make Rias angry because she knew he was being sarcastic "Why you…"

She didn't manage to finish because the fallen angel that appeared and bowed in front of Azazel. "Azazel-sama!"

Azazel lifted a brow "What is it?" "Something horrible! The Hero Faction attacked the Grigori head quarters!"

And done! Sorry for taking so long but here is chapter 6. I'll try to upload quicker because next week I got Holiday because Independence Day in my country. Also I'm thinking in writing another story alongside this. I'm working on a schedule to do that. I will probably be a Naruto Fanfic, But I'll see. Well that's a wrap. Till next time!
