-Chapter 2 : Hyoudou Issei Just Can't Take a Break-

-Nearby The Hyoudou's Household-

Standing nearby my house, I'm facing two of my schoolmates.

Both of them are quite tense and watching me carefully.

"Well, mind explaining why were you two stalking me around? One thing I'm sure that it isn't to protect me from those Fallen Angels."

"..." x2

They didn't say anything and just keep staring at me carefully.

"Let me guess, it's for observation, huh?"

The only reply I got is another silence.

Hmm...

"Um, silence might be gold, but in this situation, it's a bad move you know? I'd hate it if I have to send you two back to Rias-senpai not in one piece."

The two of them instantly took a stance.

"Hey, don't be like that."

I just raise my hand and gesture them to stand down.

"I'm just asking a question here and you two act like I'm going to kill you. Sheesh, what did your master teach you about manner?"

I scratched the back of my head while not letting my eyes off them. Interestingly, they got a little bit flinched with my remark.

Then, Kiba lowered his sword and said:

"We've been told to observe you, Hyoudou-kun."

"You know, I can tell whether or not someone is telling the truth and I daresay that I'd almost never wrong." I said while walking closer to them.

" I can tell by looking at the skin on someone's face. It starts to 'glisten' when someone sweats, right? I just analyze the extent of it. Though I can get an even accurate telling if I 'taste' it."

Standing in front of Kiba, I leaned forward while saying that as if inspecting.

Since Koneko is a very stoic person, it's probably hard to tell from her expression if I asked her something, so Kiba is the only viable option.

"Are you implying that I lied, Hyoudou-kun?"

Gripping his sword tight, he and Koneko tensed up.

"Of course not, even if you two are devils, I know that you're not the type to lie for something like this."

I smiled while patting his shoulder.

"I wonder if your master has a plan involving me to get harmed or in similar situation?"

"How dare you accused Buchou like that!"

Kiba stood his ground and points his blade at my neck.

Sheesh.

"I'm just asking, why did you get so flustered? Look, even Koneko seems calm. You should relax a little."

"Oh, look at the time! Well, I'm going back to my home if that is all. Sorry for scaring you two."

I passed the two since my house is on the street behind where they stood.

They seemed to be too tensed as they didn't realize I snuck a paper inside Kiba's breast's pocket.

Third Person POV

Both Kiba and Koneko stood there dumbfounded. No, the precise term would be too afraid.

They haven't felt such fear since the incident with their bishop which they never forget until this very day. But they didn't expect to experience it again.

That man, Hyoudou Issei, despite his eccentric demeanor, it's obviously a facade of hiding something dangerous behind it. They knew that Hyoudou Issei is fully capable of killing both of them without breaking a sweat nor having a guilt trip afterward.

Koneko in particular, scared even worse than Kiba. For her to sense the all too familiar power inside him... Senjutsu... One of the power that overwhelmed her sister to the point of betraying her master and becoming a stray.

Why would she encounter such thing again?

"Hey Koneko, let's go back alright?"

Kiba nervously offered his hand to his junior.

"Hmm."

Koneko accepted, but...

"Yuuto-senpai, what is that sticking out of your pocket?"

Pointing at his breastpocket, Kiba responded by looking down and took the paper from his pocket.

"Huh? 'You two are waiting for me to get killed by the fallen, right?' -Hyoudou Issei."

Instantly, they are letting out cold sweat from reading it.

Just how the heck did he?

"I see... You're sweating from reading that, huh?"

Came the sudden voice behind them.

Before they could turn to look at that all too familiar voice...

SLURP

Kiba's sweating left cheek was licked by Hyoudou Issei, the man they thought already returned to his home.

"This taste is the taste of liar! Yuuto Kiba!"

Both of them jumped forward and turn around to see him.

"Since when did he!?"

"I don't even sense him at all, senpai."

Each of them uttered their own confusion of Hyoudou Issei suddenly appeared.

No, they are pretty sure that his presence was already gone before they could talk to each other again. So how did he?

The only person who found that out in the first place was Koneko.

"You used Senjutsu to sneak upon us?"

Taking a combat stance, Koneko muttered.

The only thing in her mind is how he could do that?

Sure, she knew there's something weird about his 'smell', but she knew that Hyoudou Issei is a human. There's very little amount of human capable of Senjutsu, let alone the high level ones to the point of erasing his presence.

But Hyoudou Issei just did that. Just what is he? Is this why her Buchou wants to recruit him? For being an enigma that might solve her problem?

"I see that you are confused for seeing that I'm capable of Senjutsu to do such thing, huh? Miss nekomata."

Both of them perks up upon hearing that.

How did he knew!?

"Ah, there you go making that stupid face. You are correct that it's crazy for human to be capable of such high level Senjutsu, but I'm not exactly erasing my presence or possessing great aptitude with it. I'm just obscuring it with the surrounding environment. Besides, the reason of me knowing you are nekomata... Let's just say I've encounter one before." He smirked at that last part.

Then, his face lost all of the trace of being dorky or humorous.

He's serious and pissed. In short, seriously pissed.

"Back to the main topic, I told you that I'm going home and letting it pass, but the situation's changed a bit. You said that your master didn't have any plan to harm me or putting me in a similar situation. Why would you lie about that last statement I wonder? Hmm?"

With a face devoid of any emotion, he asked that.

There's only one thing going inside both Koneko and Kiba's head.

'We're going to die if we lied and Buchou is going to get hurt if we tell the truth.'

So, they took the action to ensure both their survival and their Buchou's well-being.

They launched a surprise attack at him.

-o-

Issei's POV

Really?

Launching an attempt of surprise attack to me when the situation gone bad to worse?

"Su~ Ha~"

I took a deep breath to absorb the natural energy around me and combine it with the touki and holy energy together to form a yellow aura around me.

When they got close, Koneko came first to punch my guts before Kiba performed a horizontal slash, aimed to my neck.

Neither of them connect as I grasp Koneko's left fist with my own and sent a jolt of touki mixed with senjutsu, sending her sprawled on the ground while her body is twitching around while I simply grab his sword with my right hand.

"What!?"

After getting surprised for a second, Kiba pushed the sword with both hands, trying to overpower me.

Let's punish him a little bit.

"Metal Conduct Overdrive!"

An electrical sparks traveled from my hand that held the blade toward the hilt and eventually to his hand, burning it.

"Argh! What is this!? A holy energy!? Even when I'm holding Holy Eraser..."

Gritting his teeth, Kiba tried his best to hold back the pain from my attack.

I'm surprised as to why didn't his arm melted off or get badly burned.

And I got the answer after performing a Structural Grasp to find that sword ate 'light' and 'holy energy' of a certain amount.

Though it seems like I surpassed that certain amount a little bit since both of his hands got hurt pretty badly.

Now both of them are no longer fit to fight me now that one of them got their hands burned while the other sprawled on the ground.

"Good grief."

Then, I realized what I just did.

Attacking gremory's servant in their jurisdiction.

"OH! NO!"

!?

I immediately leaped back as I sense something bad coming.

Turns out, my sense is telling me the truth as the ground where I stood previously, now turned into a small crater with smoke still rising from it.

"Good grief, attacking me that sudden, what's gotten into you, Gremory-senpai, Akeno-senpai." I said while rubbing the back of my head.

Several meters in front of me stood my senior in the school, Rias Gremory and Akeno Himejima.

They stood protectively in front of Kiba and Koneko as if preventing me to harm them any further.

"You have no right to say that after you hurt my peerage, Hyoudou Issei." She said while holding back her anger.

Hey, hey, shouldn't I be the one who felt angry?

Your peerage tried to kill me, you know?

"Ufufu, it seems like Buchou is at it tonight. Then, I have to punish you, Hyoudou-kun~" She said while licking her lips.

A sparkle of electricity suddenly appeared around her left hand.

"Permission to attack, Buchou?"

"Do it, Akeno. But don't kill him."

"Yes, Buchou~"

With that, she shot the electricity at me.

Hey, hey! That's rather large attack, Himejima-senpai! I'm going to get killed!

...

Just kidding.

"Su~ Ha~"

Taking a deep breath, I took a stance.

Yellow aura surrounds my body with the occasional electric spark flying around.

"That's!?" Rias exclaimed in surprise.

"Redirect Overdrive!"

I literally chopped the incoming electricity and threw it to the nearest tree, blowing it completely.

"Listen here, what is your problem for suddenly attacking me like that without letting me explain? Those two over there weren't hurt as bad as you thought and in my defense, they're the one who attacked me first. Sheesh, keep the leash of your servant better, Gremory-senpai."

"What!?" She looks surprised.

Then, she turned her back to confirm about it while Himejima-senpai keep watching me.

Both Kiba and even spasm Koneko averts their gaze.

Rias could only look down in shame.

Attack first, ask later?

Wow.

I don't know what to say.

"Hey, what is your real intention to send those two to me? Don't lie to me, I could tell if you lie or not."

"..."

She didn't say anything and just keep staring at me.

"Come on, I got no time for you to spaced out like that."

I impatiently tapped my foot while looking at the watch on my wrist.

Tch.

"Fine if that's what you want. I don't care too much, but let me give you this warning, Gremory-senpai. If you or any of your peerage do something like this again... Let's just say I won't be quite merciful as today since killing your kind is kinda my part-time job for the moment." I said before leaving.

They seems like ignoring me.

Either way, I don't care.

At least my message got delivered.

-o-

-Occult Research Club Room-

Saji's POV

Err...

Why am I currently got into this situation?

"Saji-kun." Kaichou who sat beside me said that.

Gulp.

This situation might looks like a blessing to me since I like her, but the current situation...

"Y-Y-Yes! Kaichou?" I responded.

"Calm down, Saji-kun. We're just going to ask a few question and your suggestion." She said while patting my shoulder.

"Yes..." I said sheepishly.

Damn, I overreacted.

I'm ashamed.

How did it come to this again?

Few Hours Ago...

"Man, this month's JoJoLion is great!" I said to no one while reading the Ultra Jump.

To be honest, the main reason why I can read this is that most of my student council job was already done and now I'm lying on the sofa, reading this Ultra Jump accompanied with some snacks and tea on the table.

Ring Ring Ring

Hmm?

"Who the heck is calling me right now?" I muttered while picking up the phone on the table in front of the sofa I sat on.

Flipping the phone open, I thought to myself if it's someone I don't know, I won't answer.

It's a bother.

With that in mind, I look at the cal-

Sona-Kaichou!?

"Eh!?"

Ring Ring Ring

The ring tone is ringing again.

'Why is she calling me at this time? Don't tell me?!' I thought before fantasizing dating with her until imagining an indecent thing with her.

Wait.

That kind of thing is impossible!

Yeah, no matter how you think about it, it's impossible!

Ring Ring Ring

The ringing snapped me back to the reality.

Click

"Yes, Saji Genshirou here." I said with a polite tone.

"Ah, Saji-kun. Can you come over here at the Occult Research Club this evening?" Kaichou said over the line.

I knew it.

I knew it, but why do I feel kind of disappointed?

"Yes, Kaichou."

"Thank you. Then, I'll see you later." She said while slightly chuckling.

"Yes!"

Several hours later, I go to the Occult Research Club room. Inside, I can see that there's only Sona and Tsubaki along with the rest of Occult Research Club members. Apparently, only me and Tsubaki were called here.

I wonder why.

Back to present...

"About Hyoudou Issei, what do you think about him?" Suddenly, Rias asked me.

Huh?

What is this about him?

He didn't do something bad, right?

"Well... May I ask if there's something going on that you asked me that question, Gremory-senpai?" I asked politely.

"Ah, I just want to know, that's all." Gremory-senpai asked.

"Yes, I also would like to listen it from your perspective." Kaichou added.

How suspicious.

But no harm telling them anyway.

"Well, he is a quirky and eccentric guy. I couldn't even understand him at all. Sometimes, he'll help people selflessly, sometimes he also berates those who 'used' his selflessness to sleaze around and despite hanging out with the perverted duo, he still remains normal as ever." I explained every detail about Issei.

I think that sums it up.

"I see..." Rias muttered thoughtfully.

"Then, that means this Hyoudou Issei is a reasonable person, right?" Kaichou asked me again.

"Well, he is. Even in that incident where he singlehandedly beaten all of the delinquents were due to their own damn fault for not heeding his warning to leave. Added by the fact that after he beat them up, he only told them to leave and not messing with the students again. Though, he kind of going overboard by crushing their balls in the battle..."

"Ara, ara? No wonder he acts like that." Himejima-senpai joined.

"Eh?" I weakly muttered.

What is she talking about?

"I agree with Himejima-san. From what you describe, Issei is a pacifist and kind person, if a bit strange. It's no wonder he acted like that." Tsubaki added.

"What did he do?" I asked.

Seriously, what did Issei do to earn everyone's attention here?

"I would prefer not to talk it, but..." Himejima-senpai replied while frowning as she turn to look at her master.

"It's fine, Akeno. I'll tell them myself since I'm the one requesting Student Council's help." Rias said.

"I understand." Himejima-senpai replied.

"The thing is..."

Then, Rias explained everything. About her plan to use the Fallen who entered their territory for killing Issei and turning him into her peerage, but failed spectacularly and get two members of her peerage suffered quite an injury courtesy to Issei and antagonize him.

"Don't screw with me! You trying to recruit him that way?! The poor guy didn't do anything wrong to you! Why don't you try to ask him?! I'm sure he's kind enough to at least listen to you." I hit the table as I stood up and yelling out that loud.

I know this kind of thing is usual to the devils, heck it's him who is being strange. But to hear this from his senior, no, someone from Gremory family who is known to love their servant no different as their family... My opinion on them became less than pleasant thanks to this.

Issei, the selfless guy who is kind to everyone and likes to help those in need didn't deserve something like this. Being repaid by getting killed for the amusement of devils, it's just too much.

"Saji! Calm down!" Kaichou said in a stern voice.

"Ghh..." I grit my teeth while slowly sitting down.

"I know you must be mad hearing one of your close friend being treated like that, I'm also displeased by her ways, Saji-kun. But still, we should think about the way to apologize to him. It won't be a good thing if a mercenary like him antagonize us." Kaichou explained in a caring tone.

"It's alright Sona, he deserve to be angry. I never took those factors before doing something like that. Sorry." Rias muttered while looking down.

This caught Kaichou off guard for a second before composing herself again.

"Ahem, you heard her, Saji. Please, forgive her. Even if I knew the blame was all on her, she didn't mean to, it's something personal that drove her to do it."

"Yes, Kaichou. Gremory-san, I also apologize for my outburst earlier." I said while looking down, hiding the expression of displeasure on my face.

Actually, I didn't even feel sorry about my earlier outburst, but this is the least ! could do to make Kaichou avoid getting into trouble or ashamed because of my act.

"Then, let us return back to the main topic." Kaichou said while fixing her glasses position.

Two Hours Later...

"Thank you, Sona. I hope that your suggestion will work."

"It's no problem. Even if things gone sour, I'll help you. But promise me that you're going to listen to me next time and don't do such thing again." Kaichou said in a stern voice tinged with concern.

After that, we are going to get back to our respective home since it's already late night. Not that it minds anyone since they're a devil anyway.

-o-

Meanwhile, Archer's House, An Hour Ago...

Issei's POV

"Are you serious?" I asked over the phone.

"Yeah, why would I joke about something like this?" The man from the other line said.

Well, he's not really the type of liar, that's true.

But this sudden?

I don't know what to say.

"So, you're telling me that one of Gregorio Zeppeli's child is going to come here as a representative of the church under the guise of unique doctor?" I asked him.

"Yeah, since I still have many business here, I recommend you to my employer and he'll agree that you'll be the one escorting and guarding her. Don't worry too much about guarding, she's more than capable to fend off anyone who tries to mess with her. Besides, messing with her will mean that someone who dares to do that declared a war against the church."

"Hey wait, you said she? Are you sure you said that right, Archer?"

"Yeah, what about it?"

"Isn't Gregorio-san only has four sons?"

"Ah, I forgot to tell you. He adopted someone into the family last year. I forgot the details about it though. Still, the mission still the same, just escort her to the place she told you, you'll know it where since it's a familiar place." Archer said while snickered in that last sentence.

I wonder who is she?

Let's just hope it's not someone too eccentric like Gyro-san.

With that in thought, I proceed to talk more with Archer about the details.

-o-

-Inside A Train, The Next Day-

Third Person POV

"So, this is Archer-san'shomeland? It's beautiful, just as Gyro-fra said." A blonde haired girl muttered while looking out of the window.

*fra = she shortens it from fratello, it means brother in Italian.

The girl leans toward the window while enjoying the view.

She wore some sort of teal colored nun outfit with cross decorating most of the places, a small luggage on her lap and a cylindrical tube strapped on her back.

But the striking feature that makes her rather unique is the shade she wore.

It's quite out of place for a nun like her to wear that.

Though, she never thought it's out of place. At least to herself.

She was tasked by the Church to be some sort of representative in this town under the guise of being a doctor.

Well, at least this is what she can do after the kindness that her adopted father did. Besides, she'd love to see the outside world rather than in the same place for a long time and practice her ability for helping people in peace.

While thinking about that...

"Everyone, get down and lay on the floor! This train have been hijacked! If anyone tries something weird, I'll shoot you down immediately!" Said a man wearing a cover on his face like a generic robber or terrorist while holding a revolver in his hand.

Everyone immediately obeyed while being scared.

Except the blonde nun with the shades who kept staring out at the environment, not even batting an eye to the event transpired before her.

"Bitch! I told everyone to get down and lie on the ground! Do as I say or-"

"Haa~" She just sighed.

"Quickly, bitch! Or I'll shoot you!"

"Listen here, mister hijacker, can I do that when we get inside the tunnel, I want to enjoy this beautiful view for a while please." She nonchalantly replied.

To her, this view is rare since this is the first time she came to Japan, so she's going to savor every moment of it.

"Screw that view!"

BANG!

The man fired a shot toward the window, shattering the glass.

The nun didn't even flinch or reacts like normal people do by panicking or something, but she sighed even deeper.

"You little bitch! Do you want to die that badly, huh!?" He points the gun at her head.

"Listen here, mister hijacker. By the time you pull that trigger, you'll regret it, you know?" She said while putting down the cylindrical tube and taking out two yellow colored steel balls out of it.

"What are you doing? Put that down! Do you want to die!?"

"I'll just give you one suggestion, mister hijacker, put that gun down and surrend-"

BANG!

"Fuck you bitch!" He spat after shooting her in the head.

"That ought to teach everyone to not do anything weird on my wat- GAHHH!" He said before screaming in pain.

Looking at the source of pain, he saw a spinning steel ball lodged to his shoulder.

"What!?" He exclaimed when seeing that.

"I told you that you'd regret it if you pull the trigger." The nun said, apparently unharmed from the shot.

"But how!? You're supposed to be dead!" The man yelled.

But he didn't notice that her left hand that held another steel ball is spinning beside her head and the bullet that was stopped on her forehead, only trickling a very small drip of blood.

"Good grief." She muttered.

"Die!" The man yelled as he tried to pull the trigger.

Tried.

"What!? Why can't I control my hand!?" He exclaimed.

Slowly, the hand that holds the gun moved.

It points at his left leg.

BANG!

And he shot himself in the leg.

"GUAHHH!" He screamed in pain as blood is flowing profusely from the wound as he fell down.

Then, that same hand threw away the gun out of the window that he broke earlier.

Seeing that the hijacker apparently lost his weapon, everyone stood up.

Then, they tried to stop the man's bleeding leg and bandaging it...

...Before ganging up on him and kicking him around.

Meanwhile, the nun just walks forward to the control room to stop the other guy.

She got the situation all under control.

But to herself, it's an annoyance since she couldn't enjoy the view until the situation resolved.

Later on she'd regret taking the situation to her own hand as she was questioned by the authority for the stunt she pulled.

"Err, miss Asia Argento Zeppeli, isn't it?" Said one of the police in english.

"Yes, that is my name." She replied as polite as she could.

"Can we ask you a question?"

She just rolled her eyes, luckily the shade prevent the cops from knowing that.

Great, first day in the town and she got involved in something like this.

-To Be Continued-

P.S. The prologue chapter was already rewritten, go check it if you want.
