the (not so) evil nun

(Issei POV)

"I... Accept." "What are you saying Asia, don leave me!" At that moment, something suddenly pushes me away from Asia, crashing me into the wall.

When I open my eyes again, in front of me is a woman with long black hair and she is holding a demonic-looking scythe, is she a reaper? "Wh... Who are you!?" I look at Raynare, this is the first time I saw her in this state, she completely fears this strange woman.

"Who am I?" My eyes widen, this voice, although it was deeper than before, can't be anyone else "I'm Asia Argento, the former wielder of twilight healing and the new user of soul scythe, a pleasure to meet you."

--------------------------------------------------

(Cain POV)

What a nice line I have there, I need to think of a name for my sacred gear identity so with my ability 'Soul scythe' seems like an acceptable name. Now I'm in control of Asia, but it doesn't mean she will stay alive, because of my curse - (Read chapter 1) - And if I'm correct, she can only stay alive for some more minutes, I can't prevent her from becoming a devil, it's inevitable.

But before that, I have to make sure that her body isn't that fragile anymore, so I used my skill to... corrupt her holy body a little to make it... more mature? I just make her hair black... and increase some of her body's strength, that is acceptable, right?

"Ah, I was lost in my thought, what were you saying again?" Indeed, I didn't hear her but on the other hand, I try to play with her too, I wonder how much power I will get from eating her soul.

"It's doesn't matter, wielding that worthless scythe won't change your fate, Asia Argento, especially in front of an ultimate fallen angel like me!" ...You know what? You shouldn't call a worthless scythe Raynare, I wanted to play with you a little longer but now? Fuck you.

I control Asia's body to use the ghostly steps to teleport behind Raynare, active Armament Haki then chops her head in an instant.

[Fatal hit!]

[Ghostly step have level up]

[Soul devoured: +10 STR, DUR, DEX, 20 WIS, INT]

[Item drop: fallen angel's feather x2]

Blood has covered all of Asia's body, I don't know why but I quite enjoy this scene, the pure angel has become a bloody angel. "A... Asia, is that you?" I use Asia green eyes - now blood red - to look at Issei, he looks quite terrified by Asia's current appearance which I can understand. "Issei-kun! are you okay?" Seeing Rias's group break-in, I stare at them for a moment then let Asia have her body back and lay next to her.

[You have completed a quest]

'Heh, neat' Without hesitation, my scythe form on the ground completely disappear, just like how a sacred gear should. Now I'm inside of Asia soul, I'm sure that I'm in my spirit form now, let's take a look around.

If you look carefully you can see a piece of this pure soul is missing and some parts of it are black instead of pure white. 'It clearly because of her missing sacred gear.... and because of my influence.'

That is the only suitable explanation for this, for now, I will wait.

{Sometime later } (3rd POV)

"My head is hurt, where I'm?" Asia shakes her head and stands up, completely dazed by the sight in front of her: an endless space filled with white and black mist.

"Look like you have arrived here my new welder." A deep voice emerges behind Asia when she turns around, her green eyes meet with blood-red eyes - (remind you that Cain height is about 5,7~5,8ft) - The man's appearance can be described as handsome but his aura only shows one thing: death. "Wha... What do you mean by your new wielder, and who are you?"

Our main character smiled and step closer to Asia while our priestess is trying to take a step back, "My name is Cain and I'm the one that speaks to you earlier." Asia look at Cain stunned, she didn't expect the one who speak to her earlier was a human... at least she think so.

"You are very confused now I can see, let me explain. First of all, I'm not a human, I'm a sentient weapon, this is the human form I have. Secondly, you are inside your soul right now... or I rather call it inner world, it can be whatever you want."

After complete analyzing what Cain just said, Asia immediately turns to Cain to ask something but he is nowhere to be found. Space slowly shifts itself to something else, when the transformation completes the scene now is resemble a familiar-looking church.

"This is your inner world so you can shape it to what you like but since you're my user, I'll have access to this too." Cain said while sitting on the top of the church, after that, he jumped down and meet eyes with Asia again "Now what does this priestess want to ask? I will gladly answer most of it."

Taking her chance to speak, Asia ask Cain "Why did you choose me to become your wielder? And can I know what ability do you have?"

"Oi, that is two questions at the same time, but fine, I will answer it all for you." Cain takes a deep breath before start answering: "For your first question, I simply choose you because you are the closest one and also the weakest one is present there, which mean you are my only choice."

Asia understands Cain's explanation but in her mind, there is still some doubt. "for your second question... I'd say that I will be on par with a Longinus in no time. What a Longinus you may ask? It's a weapon that capable of killing a god."

Asia stood there, trying to receive the information she has just given "Hey, don't make that face, not all gods are invincible, you should be happy that you have a weapon that is capable to kill a god here."

When Asia wants to ask another question, her body slowly fades away "Look like your time here is up. Make sure to visit me next time."

When Asia completely fade away, Cain sighed and lay down lazily "I still haven't finished my line yet." He stood there for some moment and suddenly realize something "Why should I tell her that she can kill a god now, she is a priestess after all, how stupid am I?" then all of his death aurae switched off

{In the real world}

"Asia, you have finally awake." Just when Asia woke up, Issei immediately hugged her making her yell in surprise "Issei-Kun, please don't surprise me like that."

"I'm sorry but I'm so worried, you have become a completely different person back at the church, I thought something possessed you." Asia confuse rise up again 'So it not a dream!' Asia recalls the conversation with Cain in her inner world.

"Ano, Issei-Kun, can you tell me what I look like back there, I don't remember anything at all." Indeed, she doesn't remember anything at all because she was already possessed by Cain at that time, Issei looks at Asia with a surprised expression.

"You don't remember anything? Back in the church, you were acting like a killer, you slice Raynare without any hesitation, your hair and eyes colour changed too."

"My hair? It's still the same here." Asia reached her hair, it still has a natural blonde colour but in the end, some black fang appear, 'Is this a side effect of my sacred gear?' normally, her hair is pure blonde, it appears that using her sacred gear cause an effect on her body.

"It appears that you have wake up Asia, how are you feeling now?." Rias greeted Asia with a warm smile, the rest of the ORC follow behind. "I'm fine thank you Rias-san." Rias sat down near Asia "Now, let talk about your condition first."

{Blah blah ya know the rest}

"Do you feeling well now Asia?" Asia nodded "Yes, despite I can't pray to god anymore but now I'm able to stay with Issei-kun now." Her cheerful smile quickly returns to her face as she hugs Issei.

"I don't want to ruin your mood but can I ask you something, Asia. What is the weapon you were using when we come in?" Rias asked, the rest of the group have the same question too.

"Eh, sorry Rias-san but I don't remember anything back at the church. But during that time, I have a rather weird dream." Rias raised a brow and let a sigh for Asia to continue "In that dream, I saw my talking to a man, he claims that I'm his wielder."

"A sentient weapon? At least it has to be a mid-class sacred gear, like your booster gear Issei-kun."

"Really? Then will Asia become strong as Kiba?" Issei asked, feeling happy for his friend's found power. "Then Asia-san, do you mind summoning your scythe here?" Rias step up and look at Asia with a slight trace of hope in her eyes.

Asia nodded and summons Cain, a demonic-looking scythe formed in an instant on Asia's hand. Rias take a quick analysis of the weapon and say "I have never known there is a weapon like this exist but its power should be at mid or high-class Longinus power. Maybe I should ask my brother about this weapon." Rias keep the last part for herself but it can't escape Cain's enchanted sense.

"Hey, it's rude to take about who is listening." A deep voice emerges from nowhere make everyone shiver, Asia notices her scythe emitting something familiar like that man she saw in her dream "Cain, is that you?" The aura suddenly stops emitting from the scythe "Ha! I don't even think that you can remember my name, little priestess. Yes, it's me, Cain, the soul reside in your weapon."

'Hehe, look at their face, such a priceless face, I gotta remember this moment.' Cain thought but unknown to him, Asia also hears his thought. "Cain-kun, that is very rude you know?" This makes Cain stop in his thought in an instant

"Wait what? You can hear my thought? Guess my soul corridor with you is a little bit more complicated than I thought." Cain mumbles the last part but still enough for everyone in the room to hear. "Ahem, sorry to interrupt you but Cain, do you mind giving us an explanation about why does Asia look like a different person when she uses you?"

"You mean this?" Cain said as he takes control of Asia's body, changing her appearance to a more devil form, "Do you like your friend current appearance Issei? I seriously like her in this form more, for a nun such as Asia to become an evil nun, why not a sinister priestess too?". Issei immediately stood up and summon his gauntlet, intent to punch Cain in Asia form.

"You bastard!"

Boost!

"Wait Issei don't!" But Rias is too late, when Issei's fist is about to reach Asia, the hand of the priestess use the scythe to block the punch with ease "calm down red dragon, do you even remember this is still Asia's body? You will hurt her body, not me." 'even he's punching me right now.'

Durability: 27500/28000

'Ho, it only deals decent damage but not bad at all.' "Fine, I won't interrupt your moment with Asia anymore, I will go sleep for a while, call me when you want." "Wait I still have a question to ask." But Rias didn't make it in time, Cain had already disappeared into Asia's inner world.

{The event in familiar forest will stay the same so I will skip it}
