(Issei P.O.V)

"Gah!"

*Crash* *Boom*

You can practically heard the sound as I feel myself falling.

"itetete… that hurt!" I shout before I finally notice where am I.

Standing on a wide plain I can see a figure stood not to long before me. When I look at the figure again there no doubt it was Senpai in his casual clothes.

"Oi! Where the heck did you send me now!?" I shout at him as he turn to look at me.

"Wha- who are you?" he show a confused look as he look at me.

"What do you mean who am I? I'm Issei your Kouhai. The fact that your holding Deflinger mean your Senpai right?" I said feeling a bit annoyed. Honestly… why did I have to get involved with his crazy experiment.

"Um… do you know him Derf?" Senpai said as he ask his sword.

"Nope, never seen him before. Is he with the reconquista… his clothes look weird." Now even Derf didn't recognize me? What the heck is going on. Come to think of it… where the heck am I?

"It's not that weird to me. In fact it look similar to school uniform… wait a minute! School uniform!? Are you from Earth?" A look of sudden realization on Senpai face ask me the question.

"Of course I'm from earth, were even attend the same school. Did you hit your head somewhere?" What happened to him and why is he here in this place who look like a battlefield?

Wait… battlefield? Now that I look closely not to far from where were standing there is a large army of people. Some holding sword, bow, axe anything that mostly use in a war. The weird thing is some even hold a wand. Are those magician? Does that mean i somehow intrude on some war. And why the heck does it have anything to do with Senpai.

Guh… all this thinking hurt. let see… after getting back from the training trip there is still time before the appointed time for the match with Raiser so I attend the school as usual. There been some rumor about some large crater or something but that didn't interest me so I ignore it. Once I arrive at school suddenly Senpai came to me and before I knew it… he strike me with Derf and I lose consciousness soon after. Honestly? Even with all that training Senpai just take me out with one strike? Then again since it was day I'm much weaker than night so that could be the reason.

Speaking of which why is it suddenly become night? Did I lose consciousness that long? Looking up in the sky the two moon glow brightly lighting up what appear to be battlefield.

….

….

Two moon?

That doesn't sound right? I look up again and sure enough. Two moon one red and the other blue glowing brightly.

"WHERE THE HELL AM I!?" honestly...there should be a limit on joke. Did I just get send to other world? If so where? Hell? Heaven? Then again if this was heaven I will be dead already. I heard Devil receive damaged just from being in Heaven.

Even so where am I? Let remember what happened after Senpai suddenly struck me.

I didn't fully lose consciousness as I can heard some talking.

But I can't quite make who it is or what are they talking about.

"You, I don't know how you arrive in this world but please escape from here. This field will become battle field soon." As Senpai said that he held Derflinger as he face a thousand army.

Oioioioi…. No matter how you look at it there no way you could win against them alone. Add to the fact why am I even here. Does that mean I have to help Senpai battle against them?

I look at what appear to be an army and no matter how I look at them they was human. Don't tell me I have to fight against them. I maybe strong than normal human is never in my wildest life I imagine I will be fighting against a human being. Are those human? No matter how I see it, it was human.

"Partner… here they come!" at Derf word I can see Senpai with a rune glowing at his left hand charged at thousand of soldier.

I was baffled at this but quickly resolved myself as I summoned my sacred gear.

[Boost!]

Better safe than sorry. Even now I'm still not sure whether I should do anything. I mean one shot from my charge Dragon shot is enough to kill normal human. Should I be bother by this. Sigh… I only want to live peacefully doing Eichi thing why am I getting drag into something like this.

Another person who I assume was commander down as Senpai went for another target at abnormal speed. Something wrong with Senpai. All this time he has been fighting using his sword as he take down one person after the other. Where is that Explosion he use when we were fighting that Fallen angel guy And where is that abnormal speed that could even surpassed Kiba? It as if he doesn't have any of those.

[Oi…are you just going to watch?]

'Gah… oh… just you. Don't scare me like that." The one who is talking to me right now is Ddraig. He Is a Dragon that was sealed inside my Sacred gear.

"I think I wait a while." I said to him. I can see Senpai can take care of himself as he knocks out another soldier.

[Partner, at your left!] at Ddraig sudden talking I move my body dodging the sword that was aimed at me.

I was so focused on Senpai that I didn't noticed I was surrounded by a soldier. Damn it… it seem I just got Drag into the fight.

[Boost!] No choice but to fight now.

XXXXXXXXXXXXX

"pant, gasp, just how many are them?" I said as I slash at another one. Right now I don't even feel anything as I take down another person using a sword I stole from one of the soldier. It either that or die. I'm not even sure whether they still alive after that. Although beside all human they seem to be non-human between them. I don't know what it is as it look humanoid but was 5-6 times bigger than normal human is.

"Hyah!" with a swing of his sword Senpai knock out the enemy using the back of his blade. Unlike Senpai who is great at using sword I 'm still new at it so I can't do what he just did.

"huff… I don't know who you are… and what the heck is that Gauntlet? But I still have to delay the enemy." At Senpai word the rune on his Left hand glow brightly and with a swing of his word a strong gust of wind form as he sent the enemy flying.

What power, just from the swing he created a strong gust of wind.

Me and Senpai back meet each other as both of us were surrounded by the horde of army.

[Boost!]

"Okay… I think that enough. Right now I'm not even sure what I should do but…

[Explosion!]

With that I can feel a strong surge of energy as I gather all of it at my Gauntlet.

The enemy doesn't seem to mind the sound of my gauntlet as I can see a row of people raised their wand as blast of fireballs comes from it as it was aimed at us.

Shit… I don't have time to charge Dragon shoot at this rate. The attack move toward us but before it could hit us Senpai using Derf parried all the fireballs one by one. Thank to that I managed to charge enough demonic energy for my attack.

"Take this."

[Dragon Shoot!]a bright red glow forming at the tip of my Gauntlet as a blast of red shot out from it as it headed to a large number of remaining army.

*Kaboom!* a large explosion can be seen as I'm sure that shot has obliterated all of them. How is this happen? Did I just take all of those human life as if it were nothing. It was now I realize just how destructive my power can be. I'm starting to have doubt whether becoming a harem king is a good idea anymore. Does that mean I have to do something like that in order to become a harem King? Is that why I was sent here?

"wha- what the heck just happen?" senpai ask with a look of confusion and a bit fear. It rare for me to see Senpai act like this so I should Savor it while I still can. Fufufufu… bow down before my awesome power. I silently gloat. It sure feel nice feeling better then Senpai. Then again he has been acting weird since now. It as if he don't know anything about Sacred gear and the like. Isn't he the one who told me about Sacred gear in the first place?

"I-it a monster!"

"Retreat!"

"aaaaahhhhh!"

It seem even the enemy had ran away at my awesome power. That what happened when you charged twelve Boost and unleash it all at once.

As I was having this wonderful feeling suddenly I notice something. It as if time itself has stop… no… time definitely has stop as I see Senpai frozen and the bird on the sky just stop there.

"W-what happened?" Did something just happen or did I just screw something?

"It seem that what the memories can sustain? I guess I must have pass up at this point of time."

"I can see that… that was a useful ability add to the fact I can see Sekiryutei power on my own."

Suddenly I heard a familiar voice and another voice I didn't recognize.

When I turn around I was met with Senpai talking with some Mysterious smiling person. This definitely the Senpai I knew since he was wearing Kuou school uniform. He have some answer to give me for all this mess he put me through. I'm pretty sure all of it is his fault.

"Senpai! What the heck is going on!?" This is without a doubt his fault seeing he just talk casually like that.

"oh… Issei… glad to see your doing well. I must say you really did a number here."

"Sigh… would you mind explaining what going on." It sure tough dealing with Senpai. Why did I become involve with him in the first place? Oh right… to get the x-ray glasses.

"Simply put your currently in the past."

Past? As if the past?

"Do you mean I'm just travel back in time?" how did that work. If I already meet Senpai then he should already knew me before I even met him. And does that mean that this event really happen. All of those people die because I kill them? Don't joke with me!

Perhaps Senpai sensing my anger quickly explain.

"Don't worry… when I said past you didn't really travel back in time."

Let me show you again but this time without interference.

[Record!] as he wave Derflinger the sword shine before the scenery around us reform as I can see myself back to when I arrive here except that this time the Senpai from before can't see me. I watch as Senpai taking out one enemy after the other but the difference is he is alone. A few spell hit Senpai as he kept going knocking down one enemy after the other until he finally stop. A fist only an inch from the commander face before he collapse because of all the arrow and weapon piercing his body as the image disappear.

"T-that…"

I was speechless at the scene. No matter how I look at it there no way for him to survive against that and yet here he is standing in front of me. Does that mean Senpai also is a Devil? Did someone revive him?

"Hm… so the spell can rewind the time without interfering with the future. I think that enough for now. I can see you still haven't recover from the previous battle."

The person I didn't recognize said. I wonder who the heck is he? Is he a Devil?

The surrounding Disappear as I found myself return to some sort of basement. If I remember correctly this is what Senpai dub as his lab. The place where he create those weird Gadget. Thank to him I have to spend the training wearing the ring that amplified Gravity and I must say Buchou really abuse the ring ability as I have to face with the ring full power.

But back to the situation at hand as Senpai dismissed whatever it is he doing he seem to staggered back a little. I wonder if it related to that big crater I've been hearing about. I still haven't met with Buchou yet today so I don't know what happened while we're gone for training.

"Um… Senpai, who is that?" I point at the mysterious man. He give this mysterious aura around him.

"hm.. oh right… I still haven't introduce him. This here is the Sekiryutei, Hyudou Issei." Senpai point at me as he introduce me. I guess starting from now the name of Sekiryutei will be associated with me.

After that Senpai make a gesture to the mysterious person asa he faced me.

"This here is Ajuka Beelzebub."

Oh… I see. So his name is AjukaBeelze…

IT A BIG SHOT!

What the heck! Why is one of the Maou doing here?

As I was pondering what the heck just happened.

*Crash! Boom!* the sound of something crashing against this room can be heard.

"Heh… it seems they got passed all the trap." The person who proclaimed himself as Maou spoke.

"I've done all you ask me… can I go home now? With all this mess I don't think I want to face Sona anytime soon." Senpai said and from the look of it even he got forced into doing it.

But back to what had crashed inside the room, when I turn around I can see… Buchou? Behind her was the member from Occult research club. Standing beside her was Kaichou follow by Fuku-Kaichou and that guy Saji.

"Saito! Do you have some explanation why you kidnap the Sekiryutei?" Kaichou said but I can feel a deadly aura from her. Crap… she right now 100 times scarier than Buchou when she mad.

"Guh… Sona.L-look… it not my plan this time. This guy force me into it." Senpai said as he wave his hand on denial. Hm… it true that he seem to be force on doing it but… I think he deserved it for what he put me through just now so I decide to be silent for now.

Then again… what happened to Buchou and the other? They seem to just finish a fight or something as I can see they look tired a bit. Even Buchou is seem to be panting a little. Did something happened?

XXXXXXXXXXXXXXXXXXXX

About thirty minute before.

Sona was in student council room as she was doing some paper work. It has been two days since that disaster and her new Servant Tiffania Tudor upon requested by the Elf Fatima return to their village to report what just happened.

After Rias and her servant back from their training trip she had fill in what happened but left the fact about Chaos and so on. It was at Beelzebub-sama suggestion. He said this should be kept as secret as possible and she should only report this only to Maou. This can only mean her sister must have already knew about this. She just hope her sister didn't go overboard by this.

"Where's Saito?"Sona ask Tsubaki the vice president who is helping her with the work. She didn't seen Saito in class today. Maybe he still taking a day off. From what she learn about his abilities most of them is taking toll from his body. Not to mention that Copy of sacred gear seem to have some side effect of his body. If he keep this up his life will surely be in danger. She need to have some talk about his power on of this day.

"I don't know… maybe he still at home?" Hm… it seem even Tsubaki didn't knew. Should she call his home to confirm it. After all absent for two days is not good. For Sona who think of school as some sort of important place she can't just ignore when people didn't come to school.

Just as she ponder what to do the door to the student council room suddenly open with a loud bam. This surprised them as Saji had stop doing his work as he look at who it is that has the gut to storm the r place full of devil.

Standing at the door was a woman with flaming red hair. And from the look of it she doesn't seem to be in a good mood.

"Rias… is something the matter? It was rare for you to come to the student council." Sona said referring to Rias Gremory the heir of Gremory and so were the president of Occult research club.

"Yeah… sorry for the intrusion but I came here to retrieve one of my Servant." She said.

Sona show a confused look at that. "What do you mean?"

She looks at Sona and Sona could tell she wasn't in a good mood. If you mess with her Servant… well here is what happened.

"Issei has been kidnapped and from the look of it, it was the work of your familiar." She said it straight without missing any beat.

"Saito! You mean he kidnapped the Sekiryutei. What make you think of this?" Sona said. Though she can easily imagined him dragging the Sekiryutei doing something. Even Saji had been a victim sometime.

"I ask a few people and they said the last thing they saw him was with your familiar." That confirmed it then.

"Sigh… that guy, it seem he caused trouble again and I'm sorry for that. Sorry again to disappoint you but I haven't seen him for this past day." She wonder why. He haven't contact her even for a second. Did something happen for him to suddenly Kidnapped the Sekiryutei?

"Is that so… do you know anywhere he might be." Rias ask.

"Hm… I think he should be at his lab." If he is at school and wasn't on class or student council that the only place she could think of.

"Okay… thank for the information. Don't mind me if I did something to your familiar." Sona can sense that she wasn't happy.

"Wait, he's my familiar so he should be my responsibilities. In that sense I will be coming with you. Tsubaki, Saji… your coming to." It would be bad if she leave Rias dealing with Saito. If he was at full strength she wont mind but even she knew that in just two days it wont be enough for him to recover even with the Help from the Elf healing magic.

XXXXXXXXXXXXXXXXX

They arrive at what appear to be where the lab supposed to be…

"Sona… don't tell me that guy just Built this kind of underground road beneath our school?" Rias ask as she witness what appear to be big underground facilities where you usually saw in Sci-fi movie.

"To be honest… the last time I came here the place is just one simple room. Sona admit her own surprised. Even Saji was left speechless by this place change within two days. Saito alone wouldn't be able to do something like this so that must mean he have accomplice.

"Hm… well we found out once we found this guy. I can sense Issei demonic energy in there." Rias said and without stopping walk into what appear to be a maze as her Servant follow her.

Sona and the other follow suit as they start to wonder what the heck just happen.

XXXXXXXXXXXXXXXX

*Boom* Rias fire a blast of magic bullet as it decimated what appear to be some sort of robot. This happen when they enter the place and when a big door prevent them from moving any further.

There was what appear to be some sort of number that need to be input right beside the door but since they don't know what it is they had been stuck for a while until Rias decide to blow the door with her power of destruction.

That wasn't a good choice as the alarm suddenly buzzing. From there many robot appear. They have some sort of human appearance beside their leg which support by a wheel. The robot wasn't just a normal robot as Sona can sense some demonic power from them. Whatever it is there no way for Saito to do it so there only one possible person she could think of. The person who suddenly show up at that battle two days ago.

XXXXXXXXXXXXXXXXXXXX

(Saito P.O.V)

Gah…. It seems I was to late. Standing at what appear to be a hole on the wall is a very pissed Sona. Damn it… i thought that trap should have delay them long enough for me to made my escape but it seem I underestimate the Gremory group. Of course with a healer by their side they could fight without worried for injuries with make them more stronger.

How did this happen you ask… well it all start after that even two days ago. The day after that accident I wasn't really at good condition with over use of my stamina. In fact you can say I shouldn't be able to move yet. But thank to Gandalfr special ability I can move my body without problem.

What special ability you said… well Gandalfr didn't just limit to Increase my strength to mastery over weapon. Once activate it will negate any fatigue that I have for a period of time I'm in Gandalfr mode. Even so that doesn't guaranteed I can move forever. Even Gandalfr can ran out of fuel. Once It happen I need to wait a while before I can use it again.

I don't want to get into detail about Gandalfr here so let get back to the matter at hand. That day as I was on the way to school. Yes school… I've been missing a lot lately so I force my body to go to school. Unlike Devil which has tougher body than human is I can't recover quickly from that fight before.

So I come to school just for the sake of formalities when someone obstructs my path. Yep… it was the guy who got me into this mess. At first I want to decline his proposal at first but when he said that he willing to exchange the devil technology with mine… I can't resist.

After that he done something that surprise me. Using his power he easily renovated my lab into something that usually appear in Sci-fi movie. I must say with a new equipment there was many thing I can do. I spend the rest of the day exchanging what we know. And I decide to skip school that day. So much for forcing myself coming to school.

I guess I have to thank Fatima healing magic as I found myself a bit better. Even Healing has it limit unless she can produce magic ring like the one Tiffa mother has which can heal a person from a verge of death.

Back to what happened when I explain about Record he seems to show some interested on it. After that both of us work together to created time machine. No just kidding… it just a simulation machine that could replay the event that happened using something as catalyst.

I tell you it was tiring to finish it in one day. I even have to lied to my parent saying I was staying over a friend house. Actually I was staying inside this new place. It even have a sleeping place complete with shower. I wonder how he built all this in just one day? Guess they don't call him Maou for nothing.

After the machine finish it was my job to connect it with Void magic. Since Ajuka want to observe and was the one responsible maintaining the spell we need a test subject. I don't know why but when I think of test subject Issei immediately came to mind.

With that thought in mind I proceed to locate Issei who seem to have been returning from his training. I thought it will hard to incapacitated Issei but suddenly I feel as if a boost of strength and speed enter my body as I knock issei unconscious with only one hit. That must be the work of Ajuka… he must have use some sort of buff at me.

After I knock out Issei I bring him to the main Lab as I put him on what appear to be a chair. After that I connect Derf with the machine. Using me as catalyst I decide to sent Issei to the battle at Saxe-Gotha. I'm a bit curious at what would happen if someone is there to help me at the battle. Ajuka himself curious about Sekiryutei own power so he agreed with me.

From there I watch as Issei fought against the army with my past self. I feel a bit guilty at throwing him onto the war but he need to get use to it. After all he is the Sekiryutei after all and from the story I heard about them they always attracted a lot of stronger being to them.

After all of that finish I must say he was doing a good job. It was hard for me to believe that it only a month ago since he first pick a sword. Guess my training really did pay off. I felt a bit sense of pride at that.

And the result is… Issei power really terrifying. Given enough time he will have power enough to destroy a whole army with ease.

Back to the matter at hand Sona doesn't seem pleased and it would be correct to say she was piss. I did kidnap issei after all but don't blame me. This guy also play a part in it.

I turn my head slightly to look at the person who become my accomplice and from the look of it he doesn't faze a bit. In fact you can say he look carefree as if nothing else matter.

I look at Sona, Saji Tsubaki and the rest of Gremory group. It look like they managed to past that security that was install at this facility. You8 can say it was Ajuka Beelzebub. when I show him the blueprint about some sort of robot he had managed to create it by the blueprint and some material I have. It seem one of his ability is to change matter o a certain object by manipulating the number of molecule and atom on an object. With that ability and my myoz insight we managed to create some sort of security robot which power up using Demonic power provide by our Maou here making them more powerful.

And indeed they were strong considering they managed to give them the gremory group minus Issei and Souna group with only Saji and Tsubaki.

"Well, well… if it isn't Rias. Long time no see." Ajuka said casually.

"Eh? Beelzebub-sama? What are you doing here?" It seem Rias wasn't expecting for him to be here.

"About that… I have some business with this men here…" He said vaguely. He better not make an escape once thing go bad.

"Sigh… let me guess. You were responsible of the Sekiryutei Kidnapping." That wasn't a question. it seem Sona had thing figured out. As expected of her.

"Haha… well I only did what he suggested."

"Oi… don't try to pin the blame on me now. Wasn't it you who said wanting to see Issei power with your own eye."

I can't believe him. He want to pin all the blame at me? Are you a de- oh wait. He a devil, and a Maou at that. But that still doesn't give him excuse to escape from responsibilities.

"Eh… but you're the one who suggest him in the first place."

It seem he still haven't given up on pinning the blame on me. You know what. Maybe I should just cast world door and escape from here. Yep… that sound good. I'm pretty tired right now. Two days rest would not be enough for me to fully recover from the overuse of void magic and that Artificial sacred gear. On top of that I even use Lifdrasir with take my life span away. Maybe I should take Sona offer on becoming Devil? After all Devil has longer life span than human after all.

"Sorry for the trouble I caused. Don't worry, Issei is unharmed as you can see," I point at Issei who stood there showing a confused look. No doubt still haven't understood fully what just happen. I should explain it to him later. Right now I rather go sleep.

"Hm… I don't know. After what you did to my servant I can't just let you go like that." Whoa… it seem kidnapping Rias Gremory servant wasn't a good move. I don't know she care about her servant like that.

"Now, now… nothing seem to be wrong right. Let not bother about this any longer in fact didn't you have your fight against Raiser Phenex later. You should converse your strength as much as possible." Well at least the Maou is willing to defend me here.

"That right Rias. He my familiar so I make sure to educated him properly later." Sona said as support to Maou word.

Wait a sec here. Doesn't this make me the only person at fault here? At the way this conservation going all the blame will be fall on me.

"Hm… I don't know…" Rias seem uncertain.

"it okay Buchou. I'm sure Senpai doesn't mean anything bad. You can forgive him this time." Oi… Issei. If you said it like that it only make me more guilty on this part. I look at Maou and I can see a slight grin on his face.

Damn it! I've been had. It was all part of his plan to make me take the blame. Kuh… as expected of Maou. He even come with the devilish plan in a matter of second.

"Um… okay. I let Sona take care of her familiar. Come on, Issei everyone, were leaving."

As they said that the Gremory group with Issei begin making a way out.

"Well then I guess I have enough fun today. See you later." The Maou said as a some sort of magic circle appear beneath him as he disappear from the room.

Oi.. don't leave me with Sona alone. I look at Tsubaki and Saji. My only last hope.

"Well then… come on Saji. We have a lot of work at Student council."

"Eh… um… yeah."

I've been betrayed. Tsubaki and Saji also leave the place leaving me alone with Sona.

"Hahaha… long time no see Sona." I said while I still thinking a way out of this. Would it be enough time for me to escape using world door? No, Sona is much faster than that so that option out.

"Indeed. I though you were resting at home because of the battle so I don't bother contacting you… and here it is to my surprise you were doing something down here." Sona said calmly but I can see the image of Asura behind her.

"Haha… well you know what they said… for the sake of science?"

"Hmph… you better prepare for what about to happen."

Kuh… it seem she just ignore my word. What to do…

"Well partner… good luck on staying alive."

Eh! Even Derf has abandoned me.

I don't know what happened as suddenly Sona body start to give out spark that for some reason I'm familiar with.

"S-sona… your body… something happened!" I said maybe it could distracted her enough for me to escape.

"Hm… I'm not sure what going on… but I feel like this is the only way for you to behave." It seem she wasn't distracted by it per sec. I guess I did gone overboard ever since I've gone back to my world. Maybe it because Louise not with me?

Sona raised her hand as pointed at my direction and from that gesture I already knew what will happen and I won't like it for sure.

*KABOOM!*

"GAAAAAAAAAHHHHHHHHHHHH!"

….

….

….

THE END

….

….

HUFF! HUFF!

That was close. It seem the explosion was to much that I even dream of the word 'THE END' for a moment there.

Sigh…. Guess I learn my lesson from this. Never ever… trust a devil, especially a Maou.


Okay… to be honest I don't know what possess me to wrote this filler chapter but here it is. I'm not even sure whether this chapter was a good one or not.

If you ask me this story seem to become more crazier as I wrote. Let see how it goes from here then.
