-Chapter 3 : Reminiscent of The Past-

Kuoh's Station

Issei's POV

I don't even know what to say about this situation...

The Zeppeli girl that Archer told me to escort will come from this train.

And this same train was hijacked earlier by two people who is currently under arrest.

Apparently, a shade wearing nun stopped them with steel balls.

When the authorities told me that her name is Asia Argento Zeppeli, I somehow wasn't surprised at all.

Steel balls, eccentric looking, those two are the prominent traits that the other Zeppeli family possessed, his name was Gyro Zeppeli, one of my mentor in the arts of Holy Rotation back when Archer introduced me to the Zeppeli family during our stay in Naples.

The guy's great, at least if you ignore his bad sense of humor and lame puns.

And probably this Zeppeli girl was affected by him...

Let's just hope she didn't get that far influenced by his antics.

I don't need another Gyro, thank you very much.

Currently, I am in front of the room where she's being held.

"Young man, you may not enter the room, there's-" A policeman said to me who wants to walk past him to the room where she's located.

"Let him pass." A man behind me said.

I stopped moving.

Not because of the need to turn back to look at the man, but more like waiting until we get a clearance.

"I am Amakusa Takumi and this is Hyoudou Issei, both of us are her escort and temporary guardian." The man said while showing a document at the policeman.

Reading it for a bit, he then allows us to enter the room to pick her up.

Entering the room, I can see a table and two chair on each ends.

But there's only one occupant in the room.

That is a blonde girl wearing a teal nun outfit with many cross symbol decoration on it while she wore a cross necklace herself. But what makes her quite weird for a nun is the fact that she didn't wear the usual veil most nun wear and a shade covering her eyes.

Geh, definitely influenced by Gyro-san.

"You are Asia Argento Zeppeli, correct?" I asked her bluntly.

"Yes, are you another policeman?" She asked back in a polite tone.

...

I am now wearing a casual wear consist of black jacket on top of my red shirt and a dark blue trousers.

She called me a policeman even then?

"Nope, we're here to escort you. By the way, are you really the one who stopped the train hijack done by those two morons?" I asked.

"Ah, yes, sorry to bother you by doing that. It won't happen again... I hope, Nuhu~" She said while chuckling at that last part.

"Alright, then I'll escort you to the location. Amakusa-san, I'll leave things about this incident to you." I said while walking toward the girl.

Amakusa just nodded and called some people using his phone, probably cleaners while I offer my hand to the girl.

"The name's Hyoudou Issei, let's go, Zeppeli-san." I said in front of her.

She only stare at my hands for a bit.

Err...

What does she wants?

Could it be that?

"Zeppeli-san, were you wounded in the incident earlier?"

"Ah, no, that's not it."

"Is it a motion sickness?"

"No, just call me Asia."

Ah, so that's what is it, huh?

"Alright, shall we go, Asia-san?"

"Hmm." She nodded in agreement.

With that, we leave the station and Amakusa behind to clean up the mess regarding that incident.

-o-

...

What an awkward condition.

Neither of us said anything ever since we leave the station.

Me being don't know what to talk about, nor does she wants to talk since she's been staring at the window of the car we're in, apparently enjoying the view.

Unable to stand the silence, I tried to start a conversation.

"It's a nice weather today, huh?"

At that moment, I feel like FATE desperately wants to humiliate me as a thunder struck nearby tree and it's starting to rain.

...

"Ah, yes, it was a nice weather." She replied.

"Ahem, how's your first impression of this town?" I asked her.

Let's hope it wouldn't be as awkward as earlier.

"Umm, it's quite nice. There's not too many buildings around and the natural scenery is good."

Hmm, that went well.

"So, what's your opinion of being sent here as a doctor?"

Crap!

Why do I feel like I'm interrogating or interviewing her?

"Well, I don't mind it. It's a nice job of helping people and by doing this, I'll be helping Gyro-fra and Gregorio-pa."

*pa = papà /padre = father in Italian.

"I see... How's Gyro-san doing there?"

"Ah! I remembered!" She suddenly exclaimed.

Huh?

"You are the Hyoudou Issei that Gyro-fra told me about?"

"Err, yeah?"

"He told me a lot about you! Archer-san too! And-"

GRUMBLE

Her sentence was cut short by the sound coming from her stomach.

She immediately blushed.

"Are you hungry?" I asked politely.

She just wordlessly nodded while blushing.

Geez...

But oh well, she might not had any meals in the train probably thanks to the incident and she travels from Italy out of all places to here, Japan.

Looking around, I could see that the rain has finally stopped, apparently FATE hates me and purposely making the rain when I asked her about the weather condition.

Not far from where we are, I can see a fast-food restaurant.

"Driver, can you pullover? You can leave us here, I can escort her alone."

The driver nodded at that and follows my order.

He is one of Amakusa's man who was ordered to be our driver.

"Issei-san?" She asked me.

"Ah, we're going to eat here since you're hungry."

"Hmm." She nodded.

Entering the building, she somehow take off her shade.

Looking at her face...

Whoa.

She's a blonde beauty.

Looking at her, I was stunned for a moment.

Is this really the girl that stopped the train hijack? Despite knowing the she's a Zeppeli, her face makes it hard to believe what she did.

A beautiful face, long blonde hair and bright green eyes. Her hair flows all the way down to her back, with split bangs over her forehead and a single strand sticking out from the top, sloping backwards.

Heck, why am I thinking about her appearance right now?

"Umm, Issei-san?" She said while looking rather concerned.

But the way she looks at me...

Gulp.

Damn you, teenage hormones.

"Ah, I'm fine, let's order the food."

-o-

Currently, we are sitting on the seat nearby the window, facing each other after taking our order.

Our order consist of a simple two hamburgers and two soft drinks.

"Amen." x2

Both of us said after finishing our pray.

"Then, let's eat." I said while unwrapping the hamburger.

She looks at me for a while before doing the same thing.

"Asia-san, do you never eat a hamburger before?" I asked before taking a bite from mine.

"Yes, I never eat hamburger before, but this hamburger looks a lot like sandwich if its a bit thinner." She replied while taking a nib at her own.

Quickly chewing before gulping down the food in my mouth, I answered:

"Oh, it's rather same. But hamburger kinda bigger than your regular sandwich back in Italy." I explained.

"I see..." She said while sprinkling a bit of black pepper on her hamburger.

After that, we chatted about food for a while before going back to the car.

Looking at the bright sky with no trace of the earlier black cloud, an idea popped into my mind.

"Driver, you can leave now. I'm going to escort her myself."

He just nodded before leaving.

Seeing that, Asia was puzzled.

"I'm doing this so that we can go around the town, you'd want to familiarize yourself with this town if you're going to stay here."

I smiled while offering my hand to her.

"Ah, I see, just like Gyro-fra said." She lowly mumbled before taking my hand.

With that, we walk around the town.

We visited many places.

A game corner, photo booth, and finally the town's park.

Hilarity ensues when we go to the former two.

In the game corner, Asia played a game of riding a horse... And somehow, it's her first time yet she broke the record of highest score, shocking everyone present. Apparently horse-riding is something she made a hobby of after being in Gyro presence for a while.

Meanwhile, in the photo booth... Let's just say she did many weird poses that made me tried to hold my laugh so hard.

Currently, we are in the town's park, taking a break from all that activities.

"Are you having fun, Asia-san?" I asked while giving her a canned beverage I bought from the nearby vending machine.

She took it before opening it to drink the content.

I bought her a simple orange juice while I bought a cola to myself.

Apparently she dons her shade again.

"Ah, I'm definitely having fun. Gyro-fra was right when he told me about you." She said before taking a sip.

"Really? What did he tell you?" I asked while sitting down beside her on the bench.

"Oh right! I forgot to tell you about that earlier!" She exclaimed as an expression of horror appeared on her face.

Eh?

I didn't force her to tell it, but...

"Gyro-fra said that you are a fun guy to hang around with, nice, reliable if a bit eccentric." She explained.

"Ha! Says the eccentric guy himself!" I huffed.

"Nuhu~ He also said that you are one of the most determined person he ever seen." She chuckled a bit before saying that.

Determined?

Wait...

Don't tell me.

Looking at the expression on my face, she immediately responds:

"Yes, he told me about how you begged him to teach you about the Holy Rotation art and won't stop pursuing him until he agrees to teach you about it."

I looked down in shame.

Not because of I regret it, it's actually the opposite.

It's the proof that I'm not easily given up when I face a problem.

But...

"Did he tell you about 'that'?"

"Ah! The one that you were told to clean, hang your jacket, rinse and repeat?"

I could only look down and blushed.

Yeah, I was told to do that.

I thought it'd be like in that Karate Kid movie where the mundane activity we do are connected to the martial arts.

But that guy...

He told me to do that for a while, then out of nowhere telling me to stop after he was no longer amused. And when I asked him if that is part of the Holy Rotation training, his response:

'Of course not, I was just interested in how serious you are in listening to my order like that. It's amusing to say the least.'

That moment is the moment when my head went blank for the first time.

The guy's just trolled me.

"About Archer-san." She suddenly said.

Oh?

"Yes, what about that white haired snarky guy?" I asked her while sipping my drink.

"He's the one who saved me two years ago from some sort of a ritual conducted to summon an ancient monster. Luckily, Archer-san and Gyro-fra came in time to stop the ritual and save me and few other nuns."

So that's the story he told me two days ago!

"Pardon me to ask this, but how did you get adopted by Zeppeli? I know that Gregorio-san isn't someone who particularly cares about others than his family and his job. I don't mean offense, though."

"About that..."

Then, she began telling me about her life.

"I was told that I had been found crying in front of a small European town's church. I was raised there as a nun. When I was eight, I healed a mortally wounded dog nearby the church. I prayed hard at that time and suddenly, a miracle happened. The miracle that I would know later to be the awakening of my Sacred Gear, Twilight Healing. Soon, I was taken to a big church where I was ordered to heal illnesses and wounds of the believer and exorcist coming from all over the world. That time, I was so happy that my power could help people! It's all that mattered." She muttered while closing her eyes as if she recalled the scene.

"I see..."

So her childhood is nothing more than being the golden goose for the church, huh?

Can't say I'm very devout, but I wonder what God might do if He found out that one His child got used like this. I doubt He'll be pleased knowing it.

"Then, that day came."

"That day?" I asked.

"Yes, when It was a day after I was rescued by Archer-san and Gyro-fra who was at the time, still a stranger to me, I was just taking a stroll nearby the church where I live, I found a man who was badly injured and healed him with my Sacred Gear without second thought. Later, I would found out that the man I healed was a devil and by doing so, I was branded as a witch and almost got exiled. But then..."

"Then?"

"That day in the court, when they almost sentenced me to be exiled, Gyro-fra stood up for me."

Flashback.

"You! How could you brand this kind girl as a witch and trying to exile her after all she did to the church!" Said a man out of the blue while pointing his finger at the judge.

The man is of average to above-average height and medium to athletic build. He has light collarbone-length hair, light eyes, square patches of facial hair lining his jaw, and painted lips. He wears a prosthetic teeth chiseled with the phrase "GO! GO! ZEPPELI".

His outfit consists of a short-sleeved studded black leather coat, leather pants, and cowboy boots. He wears a belt, the buckle of which bears a pair of hands pointing to his crotch, and at his hips a pair of special holsters for a pair of Steel Balls. He wears a wide-brimmed hat, with slits on the the crown and the brim that let light and air filter through. Situated around the crown of his hat are a pair of slit goggles.

Despite his eccentric get up, in no way what he said earlier was a joke.

He was seriously pissed at this.

The girl that he and that snark-ass white guy rescued few days ago is a very kind person as far as he can tell and now she's being sentenced for this cruelty just because she healed a devil?

"Shut up, Gyro Zeppeli! While your family might be one of the greatest exorcist and medic family that serves the church since long time ago, you have no right to interrupt this court! Our decision is just like what God would do!" One of the judges said.

"God wouldn't abandon someone like her!"

Asia herself who is standing in the middle of the room couldn't understand the man's action.

Why would he stood up for her despite it's her own fault that she got into this situation.

"Be quiet, Gyro Zeppeli! You have no right to question our decision unless you want to be considered as a Stray!" The other judge spat.

"Then make me one! If that could mean that I'm free from your control and able to protect her, so be it!"

"How dare yo-" The first judge was going to shout, but immediately stopped.

"Silence!" Shouted an old man.

From his appearance, his age might suggest he's around fifty from the wrinkles on his face and his grayed hair. He has the same light green eyes like the youth who defies the court and a symmetrical lighting-shaped hair on both cheeks.

After saying that word, the court was suddenly filled with silence as opposed to what happened earlier.

"So, Mister Gregorio Zeppeli, I presume you have something to say about this situation?" The old judge in the middle said.

Apparently, he's the only judge who didn't snap at Gyro earlier and looks much wiser than the other two judges beside him.

"Seeing that my bothersome son acts out of his way to try to save the girl that he's never close with nor know for long time, I'm truly sorry for that." He said while bowing.

The two judges just snickered while Gyro stared in disbelief.

"But! I propose this. Since her Sacred Gear is very useful for us, it's a waste to exile her away and potentially making her siding with the enemy, so I will adopt her into my family and my son will take responsibility of her actions since he's that stubborn to save her. But remember this! As she's a Zeppeli, her obligation to serve the church as the healer would be invalid, but she'll take a support role in some of the exorcist mission and took the same role that every Zeppeli serves for over a hundred years."

"Father!?" Gyro exclaimed.

"What!? I thought you were smarter than that, Gregorio Zeppeli!" The judge on the left yelled out.

"Ha! Gregorio Zeppeli, known to be a man who avoids every sentimentality, trying to help a witch? What a joke!" The judge on the right followed.

Despite loathing them with all his passion, Gyro couldn't help but agree.

Why would his father helped her?

Seeing his confused looks...

"Gyro, I'm not doing this for you or out of my sentimentality, but I merely gave the best outcome of the situation you got yourself into and I would expect that you would take the full responsibility for that." He reprimands his son.

After a few moments of silence.

"Alright, we'll accept your proposal. But remember this, if that girl was caught doing something similar again, know that your son will be blamed and the Zeppeli's name would be forever remembered as a fool." The middle judge said while the other judges beside him smirked.

Flashback End

"After that, Gyro-fra began teaching me about Holy Rotation art. Gregorio-pa still never talk too much with me except when he critiqued me when I'm doing the Holy Rotation wrong. Despite that, I know that deep down, Gregorio-pa is a kind person. Besides, by living with them, I learned a lot of things from Gyro-fra and his little brothers."

What a deep story.

But I also wonder why when I hear the part that she learned most of the things she knew from that guy, I kinda get an uneasy feeling?

"what did he teach you?" I asked, hoping it wouldn't be something weird.

"Ah, he taught me about Holy Rotation art, modern things, horse riding, jokes, and puns. He's a funny and kind person."

Oh crap.

Someone who thought Gyro's jokes and puns were funny.

"Err, let's move on. About your Holy Rotation. It's one of the healing method you're going to use as a doctor here, right?"

"Ah yes, what about it?"

"How is it possible for you to master the healing art of Holy Rotation? Even I could barely learn the basic and only proficient at the offensive function of it."

Yes, Holy Rotation.

The unique arts that was passed down among Zeppeli's family since hundred years ago. It was rumored that the first Zeppeli who used it was given the instruction to perform Holy Rotation in a dream by out of all things, Jesus and in the morning, he already mastered it. But it's just a rumor. The technique itself was divided into two parts, the offensive and healing. But both have the same principle, they were described as the extension of a basic property of nature, the technique often involves the use of the phalanges, hand, wrist, elbow and shoulder, to the entire body (and beyond) in spinning a ball and/or launching it with the aim of exploiting the Magnus effect (whereby in flight, a spinning ball, by deflecting air flow, curves from its principal flight path), calculating trajectories with reference to golden rectangles in the environment while imbuing the Rotation with small Holy element that will slowly builds up and will spread even more when it connects to the target. Objects imbued with the Holy Rotation have a range of effects on humans, animals or the environment, though the devastating destruction is an obvious effect to those who are weak to the Holy elements. The latter one is obviously used as an offensive capability. While the healing capability offers many unique ways to treat an injured person such as twisting the flow of their blood during a bleeding, causing the blood flow to get around the bleeding part and avoid dying from blood loss, twisting the skin until it closed the open wounds, and many things even closing a hole on the vital organs if the user mastered it enough.

"About that, Gyro-fra noticed that I'm more talented in the regards of healing type of Holy Rotation so that he taught me all he can about it before passing down the advanced form of healing usage to Gregorio-pa while he taught me a bit in the offensive department."

"I see... Well, it seems like it's evening soon. Amakusa is going to get worried if I don't escort you soon." I muttered while looking at my wrist watch.

"Sorry for taking your time then, Issei-san." She apologized.

"No, no, no, it was my fault, don't blame yourself."

With that we leave the place and walk toward the destination.

When we got near the destination...

Is that a car crash?

We spot a car hitting an electric pole.

But the most disturbing fact is that...

That car is the one that we've been in before.

We ran forward to check on it only to find a corpse of the driver in his seat with a large gaping wound on his chest.

Asia could only put her hands on her mouth, shocked by what she sees right now.

"It's my fault..." She muttered.

"No, it's not. We all knew that this might happen despite the unlikeliness of it happening, but I didn't expect them to blatantly do this. Besides, if we stayed in the car, it wouldn't be only him who died here." I explained while taking out my phone.

Then, I called Amakusa and telling him about our situation.

"Alright, the cleaners team are going to be here soon, so let's ju- GHH!"

Before I could finish my sentence, I was greeted by a nauseating feeling.

This feeling!?

It's the same one as what I experienced against the Fallen Angel!

As if on cue, the sky's color inverted and turned dark.

"Asia-san, stay behind me. I can feel something very wrong going on here." I said before projecting a pair of black and white sword, Kanshou & Bakuya in both hands.

Asia nodded at that and stood behind me.

"Is that your Sacred Gear, brat?" A voice from above can be heard.

Looking at the source of voice, I found a man wearing a long coat with a fedora standing above an electric pole.

But behind him, there's a pair of black wing no unlike crow or raven ones.

"It seems like Raynare overestimate you. Looking at you now, I think Raynare must be joking around." The man chuckles.

So this guy is an associate of that Raynare, huh.

"Who are you and what exactly do you want here? Revenge for me attacking your friend?" I asked while tightening the grip on my sword.

"My name is Dohnaseek and brat, you said revenge? Why would I do that when you couldn't even scratch Raynare? Besides, my goal right now is to take that girl which should already be done had you two not leave that car. Move aside and I'll spare your pathetic life, kid."

!?

He's the one who did this!?

Ghhh...

"I refuse! Like hell I would let her be taken by your group."

"Then, be prepared to die!"

With that, the man lunges forward with a pair of lightsaber in both hands.

"Asia, stay back!" I warned her to stay away from my battle.

She nodded before moving away from my position.

Good, now I don't have to worry for her to get caught in the crossfire.

CRASH!

Both of our weapon clashed, creating a shower of sparks.

But...

"I won, brat." He smirked while looking at the direction behind me.

!?

Taking a glance to what happened behind me.

A woman that I've met along with Raynare before, Kalawarner if I'm not wrong charged from behind toward Asia.

I quickly parried away Dohnaseek's attack, stunning him a little bit.

"WOOOOOOOOOOOH~ Overdrive!" I took a deep breath before kicking him with the Holy Wave.

"GUHA! IMPOSSIBLE! RAYNARE WAS TELLING ME THE TRUTH!" He exclaimed as he was thrown backward.

The result is that now there's a gaping hole in his chest while burning sensation of Holy and Senjutsu coursing through his body, in short, he'll die.

But apparently that didn't faze the incoming ally of his toward Asia.

Damn it, at this rate, I won't make it in time!

"KYAA!" She screamed as she was taken by the Fallen Angel.

"ASIA!" I yelled as I dashed forward, trying to reach her to no avail.

"Ha, with this, Dohnaseek's sacrifice won't be in va-!?"

!?

Looking down on the supposed to be captured Asia, Kalawarner only found a nun robe and Asia's luggage in her hand.

Where's Asia?

"Good grief, luckily I wore something like this behind that robe." A voice behind me said.

Both me and Kalawarner turned to look at the voice.

At the most least, I'm surprised at what I'm seeing.

There stood Asia with her shade, but her outfit...

A sleeveless black shirt that exposes her midriff inside her vest, a brown leather shorts, a belt, the buckle of which bears a pair of cross, and at her hips a pair of special holsters for Steel Balls.

Basically, her getup is similar to those of cowgirls(mind you, a real cowgirl, not that kind of cowgirl).

"How did you!?" Kalawarner exclaimed when seeing her.

I can't blame her.

Just what the heck Gyro taught her?

I get it that Zeppeli family are the family that serves the Church as both their combat exorcist and medic, but she's geared toward the latter if what she told me is true.

!?

Is this why Archer told me that I should worry about escorting her rather than guarding her?

"Listen here, why would you kill that driver like that? If I'm the one you looking for, you should just ask, you know?" Asia said.

"Hmph, if you say that, why don't you let yourself be captur-"

"But! You already killed that man in cold blood, not even knowing that he has a life of his own or if he has a family or not. People die when they are killed and there's no way to bring them back. So, the situation's changed. This is now personal!" Asia shouted while pointing her finger at Kalawarner.

She just snorted before chuckling.

"Personal? What can you do if I do this! Mittlet!" Kalawarner shouted.

As if on cue, a gothic-lolita dressed blonde appeared from behind Asia.

"Badly injure her, but don't kill her, Mittlet!"

"Okay~" The blonde gothic-lolita replied before a pair of black wings appeared behind her and she flew toward Asia with a light spear in her left hand.

I won't let her!

"Wait, you think I'd allow you to interrupt? Now that I know what you capable of thanks to Dohnaseek's sacrifice, I'm not going to fall from the same trick." Kalawarner said as she blocked my path.

Tch.

Looking past her, I can see in a slow motion that the Fallen Angel named Mittlet is getting closer while Asia took out a yellow Steel Ball from her left holster.

The one who strikes first will win.

Asia, be careful!

To Be Continued...

A/N: Nothing much to say other than answering some bits of question.

HolyKnight5 : For Asia's shade, it's not mystic eyes, she just likes to wear that.

LL : Nope, there's no DIO in this fanfic, but you might guess who will be quite close to him if you caught something in the previous chapter which I won't tell.

Remzal Von Enili : No Pillar Man.

That is all and thanks for all the review, favs, and follows.

P.S. To those who read my other fic, the next Arc will revolve around Kara no Kyoukai element so stay tune(Wait for the update though, cause I'm writing two fics at the same time).
