First of two chapters for today and ultimately this story.
I'm doing this to make up for my lie at the start of the previous chapter. :P

True to my word, a week after the following Monday I teleported into the Occult Research Club at Kuoh Academy surprising the three girls that were there.

"Reon!"

Rias shouted happily at my random and sudden arrival but her happiness wasn't something to live for very long. I just gave her a short smile and looked to Aika who perked up slightly and came over to me. Seemed like she was a little bored here, maybe I should give her something to do in the future.

"Where are you taking her dear?"

As I continued to look at Rias I could see a thin film of crimson starting to envelope here. It was either anger or jealousy, commonly know as the same damn thing with women though. The right thing here would be to tell her the truth but honestly that's never what I would choose in a situation like this, seeing Rias jealous is funny.

"I'm taking her to a dark and secluded area to see how flexible she is after her training?"

While saying that I would never tell the truth, that's also a little wrong. I enjoy twisting the truth you could say, giving it a different appearance in this case. The Stray Devil that we will be fighting is in a desolate and secluded part of the city and i'll be seeing how strong Aika has gotten, good flexibility will show if she can evade attacks well but that's obviously not going to be what gets across when you are talking to an already jealous teenage girl … well, any girl for that matter.

This situation in itself is one that has happened a number of times before, when I say that I mean I basis that Rias gets jealous due to something i've done which is typically with a girl that's not her. Despite her jealousy and anger right now, she knows I'm only kidding and that I actually have the right to do what I joked about due to being devils. The problem is that she's a Gremory, her emotions are top-dog. Her emotions will always get the better of her, no matter what. So there is only one real way to get away from this predicament that I constantly put myself into and that is to disappear and that's what I did.

…

We reappeared in an empty park on the west side of town, the paved floor of the park had a nice, red sticky look to it probably due to the blood of the people or things the stray devil had killed. Luckily for me, we didn't have to wait long for the stray devil to make it's appearance and it was a tall one at that.

Out from the shadows came a double-decker sized spider with a human's upper half positioned atop the front bulb. It's 8 long and thin legs shot upwards and sharply shot back down into equally sharp spikes which poked holes in the ground where it stood. Strangely though the pincer like mouths of a spider were gone and replaced by scythes which came from the shoulders of the humanoid torso rather than arms themselves. While it was a frankly disgusting view for anyone to see, it wasn't enough to faze me as there are annoyingly much worse than what's in front of me right now though it didn't stop Aika from letting her lunch come to the surface.

The stray seemed to take that action of Aika's as a chance to get a quick hit in whether it was fatal or not, the spider's movement seemed almost lackadaisical. Thanks to that I was able to push my own body into motion and stand in front of Aika to take the blow for her, and while it still hurt a little it was better me than her as despite my body being easier to destroy than others it would still stop an attack like a normal body would or could and then regenerate straight afterwards.

Deciding to keep this strictly to just Aika, I raised my hand and let loose a strong gust of wind which created a considerable gap between the spider and ourselves. Tilting my head slightly, I looked behind me to see Aika now looking composed. I gave her a light nod and stepped to the side allowing her to take centre stage against the stray.

"Rook!"

Aika called out her promotion while summoning forth her Sacred Gear. I was pleasantly impressed that she was using her brain about the Promotion.

Black shadows gathered around the ends of her limbs as the Sacred Gear manifested themselves. Around her forearms appeared midnight black gauntlets with two brown jewels on the outside of each, they were bulky looking and it's weight showed as Aika's arms dropped slightly under the weight before they were brought back up again. Sharp and ridged claws wrapped themselves around her fingers before a thick plate took form over the top of her hand slightly overlapping her knuckles. Clawed boots then took form around her feet taking on the same colour as the gauntlets, two brown jewels appeared once again albeit appearing over her ankles with one to each side of the boots. On the back of each boots appeared a curved plate of metal which ended in a spike that faced downwards, it finished centimetres above the ground.

Aika's Sacred Gear was called Triumphant Wall and it's ability is pretty much as it sounds. These boots and gauntlets make her an immovable wall if used correctly. All in all, the simple evoking of the gear increases her physical defence along with an enhancement to magic resistance. A well timed guard will dramatically lessen the effect of an attack on her, of course guarding doesn't just become second nature to her though. The claws and spike on her boots act like anchors securing her to the ground when needed so Wind magic and explosions won't really phase her at all.

This is a particularly rare Sacred Gear making it a top-class Sacred Gear resulting in the 4 Pawns needed to reincarnate Aika, this would also mean slightly less training needed for her in certain regards. From there, Aika charged and took the offensive.

As I stood back and watched the match I could tell that she was still green but I felt like she was nearing the end of it. After her training with Sabrea I could see that her guards were getting better and timing was slowly becoming better but she was still yet to get a perfect one. That showed the effect of her Sacred Gear, the difference between a split second is rather big in this case. Her ability to evade attacks wasn't that great, not really that essential when in Rook mode but that's not the point. The Rook gives you the ability to take them at times plus with her Gear attacks can be nothing at all against her. Her timing for her evasion goes to show that she isn't yet well versed with a Rook's style of combat. This hurt her on two occasions in this fight when she was struck by the spider's acid, though they weren't fatal hits.

And like I had expected, she was able to win the fight but not end it. She was hesitant to kill the stray so I did so before the stray could completely gather that fact and act on it. After pulling Aika away, I set the stray ablaze in an orange inferno reducing it to ash.

…

Later that night it was just me and Aika yet again, albeit this time it had slightly less chance of death. I was taking Aika to get her own familiar, a job I have never really been that bothered with doing. I would be much happier to just teleport them there at the time and allow Satooji to do the rest but that isn't allowed, devils cannot enter without their master or so the rules say. Satooji definitely didn't say that because he is one crazy fellow, the tally has chalked up to nearly 8,300 devils that he has told to acquire Tiamat the Chaos Karma Dragon who is also the only female of the Dragon Kings. Better yet he is slowly approaching a whopping 480,000 devils that he has nearly tricked into acquiring a Hydra, a slightly scarier tally is that 41,000 outside of that has been persuaded by him to do so and half of them came out with their lives and only 2 devils out of that actually got the Hydra as a familiar. I had a few words with Satooji when he suggested a Hydra to Sabrea, luckily she just deadpanned and said 'kitten'. Not something I'd deny her when she looked up at me with her ears out.

Satooji arrived shortly after we did and introduced himself in his typical, eccentric manner. Something which deterred Aika greatly if her expression was anything to go by, she really did not look happy at his introduction. Contrary to popular belief in the Underworld you could actually go to the Familiar Forest any time as long as you had permission from Satooji and you had told him when, the reason why coming at Full Moon became a norm was because the rarer and stronger familiars were awake and more commonly found. Another instance I found slightly strange in terms of the Devil society due to us not needing strong familiars because all they do are odd jobs which amount to very little. Though thinking about it, we are embodiments of greed so that's probably a reason at least.

After his introduction we set off into the forest. I walked next to Satooji as we talked and Aika followed just behind us keeping an eye on whatever was around us.

"So Reon-dono, your twin came here a few weeks ago with 3 new girls."

"3? So he finally got his harem then. Let me guess, they got the weakest familiars going?"

A light chuckle came from Satooji to let me know that I was right on the ball yet again about Raiser. This is probably one of the few instances that I will agree with Raiser. There is no need for your familiar to be strong because their duties don't need them to be strong. If you want a strong familiar then come back on a later date after getting your first familiar, there is nothing stopping you from getting two. There just isn't really any point for more than one.

"Reon-sama, you have a twin?"

The three of us stopped abruptly after Aika brought up that question. I never really went into my family much with her, she knows my parents are still alive and of course Ravel.

"That I do Aika-chan. I actually have three brothers really. Two older ones who are really nice once you've broken through the exterior, my twin however is everything i'm not. We are two sides of a coin and i'm not tooting my own horn in the slightest when I say this but i'm the good and he is the bad. Ask any devil and they'll tell you the same thing. Unfortunately, you'll be meeting him soon as the school year break is coming."

Outside of Raiser's Queen, you'd be very hard pressed to find someone who can say a genuine good word about Raiser and truly mean it. Though there is one universal thing the devils can say about him, despite his peerage just there to suit his tastes for a perfect harem they all do at least have good potential. That's something I can't deny him at all, the only problem is that bar his Queen they are all just reincarnated humans with nothing special. There is two cat-girls though if I remember correctly.

"Stay away from him. Got it."

"That's a good girl. I say twin but it won't be hard for you to tell the difference, after all we are very different people."

Our journey through the familiar forest took a quiet turn at this point and bore only one note to take and that was the familiar that Aika finally chose after nearly half an hour of looking, not that we weren't spoilt for choice. What she had came upon was a Were-dog, it's basically a werewolf but where they have human forms as well as the Werewolf and a wolf form these just have the 'Werewolf' and then there dog form. This particular one was a cream colour and it's dog form was that of a labrador pup, one which on sight sprouted thoughts into my mind and ones that rang true when Aika decided to hug it while calling it Marley.

At that moment, flashbacks of 'Marley and Me' sprung into my mind and as the true wuss I am to these kinds of things they weren't very flattering to my pride as a male devil.

I don't see a need for a long A/N here so i guess i'll just say that this is a filler chapter.
I just wanted to show a bit more of Aika's integration in the devil sense rather than family sense which will definitely come at a later date.

Ciao, i'll see you again in the next chapter.
