Her Promise

I was calmly drinking my afternoon tea in a garden in our Kuoh Academy when my brother suddenly appeared while yelling my name.

"What's wrong Nii-san? If it's not important then leave. I don't like you disturbing my afternoon peace with your rambling." I continue to calmly drink my tea. 'But how odd Nii-san never panic and desperate like this.' But inside I already thinking several reason why he act like this.

"A-asia she was kidnapped by the Fallen Angels while we're hanging out yesterday." He said in depression. I almost drop my cup of tea because surprised but I quickly hold my cup tightly as the cube suppressed my emotions again. "Calm down. Explain how this came to be?" I open my cold eyes and stare at my brother. He immediately calm down after seeing the ice in my emotionless eyes. As soon as I said that a blue screen appear in front me.

[New Mission]

Save Asia Argento from the Fallen Angels.

He then start to tell me about when he first meet Asia again in a house where he supposed to have contract with the man inside but only find the man crucified in his home and dead. The one who killed him is a mad stray exorcist named Freed. Asia then come in after that. The stray exorcist started to run his mouth and told her about his brother current race. They then forced to separated before they can explain each other circumstances.

But for some coincidence my brother able to meet Asia while she went shopping. They then spent sometimes together. Asia went missing for quite a while alert the fallen and they went to fetch Asia. My brother told me about how the fallen planning to extract her Sacred Gear for themselves as Asia too useless for their purposes.

My brother fought them but he lose pretty quickly, Asia being the kindhearted girl decided to go with the fallen willingly if they left my brother alone. Fortunately, the fallen loss interest with my brother because he so weak. They agree with Asia and left my brother with guilt. My brother then go to his current master Rias and ask her to help him rescue Asia. But Rias logically refuse, because she think that the fallen can use this opportunity to cause war.

Speaking logically Rias is right but for my emotional brother that was the worse answer he got. So, he came to me hoping I will help him.

"I see. Fine, I'll help you. It's seems, I own her a debt for saving your life." I put down my finished cup of tea and stand up. My brother smile happily hearing my answer, he probably half expecting me to refuse him. "Hn. You probably just going to run towards the church alone without any plan if I refuse you." I said while smirked at my brother whose face lit red embarrassed.

"How predictable. Now that conclude, you two can come out now or else." I glare toward the forest near us as I pointed out the two devil that have following my brother since the beginning. Kiba come out first with serious face along with Koneko who hiding behind him as I can feel she still afraid of me.

"How did you know?" ask Kiba suspiciously. "Hn." I grunt and left towards the church without saying anything, but a crow soon preach on my shoulder for a while before flying away.

Koneko widened her eyes in surprise "That crow... Don't tell me!" Nii-san and Kiba look at her confused but also focus their intention to the crow that just fly away after preaching on my shoulder.

I let out a smirk "I see you notice, you're using Senjutsu right now." Koneko look surprise before wearing her emotionless mask again, bet her eyes tell me that she want to face her fear.

I then feel my emotion being suppressed once again by the cube making my face become blank again. "Come, Asia is waiting." I said calmly. They finally quite, I focus my way towards the church with devils behind me.

We then arrive at the church but the devil looks a bit uncomfortable near the church. I think this maybe a disadvantage for them so I'm going to make it fair. I put my hand to the church wall and break the blessing barrier that almost run out off energy.

A loud glass breaking sound surprise the devil but they also confused when they no longer feel the pressure of God's Blessing. "My body no longer feel heavy." Said my brother while checking his body as if some other irregular thing going to happen.

"I broke the blessing that put on this church. With this you devils will able to fight normally. Come, we have no time." I walk inside hurriedly. "What did you mean we have no time!?" Yell my brother worried.

"After I broke that blessing, I can feel Asia underneath us with several exorcists and a Fallen. But the problem is I can feel Asia life force is being forcefully drained out, if we don't stop the thing that pulling her life force she will die in 30 minutes." I reach the altar and use Senjutsu to flip the altar with one hand. Beneath the altar I found the hidden stair to the ground.

My brother immediately run to the underground to save Asia. While Koneko immediately ran to catch up with my brother, Kiba doesn't. He summoned his sword and point it at me "How did you know what's happen down there?" He ask coldly.

"Why I should told you about it?" I glare at him back. He flinch but recover and glare back at me. "Hn. You have backbone at least. Very well, I use Senjutsu. You believe it or not is up to you. But right now I can only trust Koneko to keep my brother save." I smirk and stop intimidating him.

"What did you just mean?" Ask Kiba this time he feel confused at my sudden change of attitude. "My crow found out that there is three fallen that reside in this place, but I only found one down here. The other two currently in the church tried to ambush us right now!" I explain as I release the wind spear that I made before I enter this place as I felt them stalking us in the middle of our way here.

"AHHHHH!" The two fallen angel yelling resound in the dark church. The two fallen that have been hiding in the shadow of the roof fall down simultaneously as I pierce each one of their wing.

"Agh! How can a human find about us!? We have already hide our energy, smell, and even wear an invisibility coat!" The older one start yelling as she can't believe she was found out by a human that she been underestimate.

"That's because I'm different." I said casually as I took step toward them calmly. "Ahh!! What did you do!? My whole body can't move just because this small scratch!" The little one yell as she realise that she can't move anymore.

"I has cut all of your nerve that connecting the control of your body to your brain." I took out the Moon and prepare to cut these pest that dare to hurt my brother and my new friend. "What! That's impossible!" Yell the older one once again.

"But in reality both of you unable to move. I have been special since as long as I remember. My sense always so sensitive that make me paranoid over single simple thing. I notice you because my other specialty. I'm an empathetic. A very sensitive one. That's why I can feel your negative emotion towards me even before we arrived at this place." The Moon glowing with darkness energy that I need to kill these pest.

The despair on their face make them desperate "P-please we just following Raynare order! We haven't done anything to hurt you! We're innocent!" They plead at me.

I stop my movement "Innocent?" My hair cover my face making them unable to see anything. Their face lit up happily as they thought I can't feel their emotion. "Then what about yesterday that day you almost kill my brother and hurt Asia because you're enjoying it." I lift my head and stare them with my cold expressionless face. My Sharingan spinning while responding toward the cold fury that manage to leak out from the cube control.

"Do you think I'm so stupid that I can't know that you're lying? Even without my empathetic sense I know you're lying." They look very afraid now, their whole body shaking with fear as if the God of Death just standing in front them. The despair that they felt when they saw the dead red eyes piercing their very soul.

"Begone." I swing my sword and it let out the undying darkness fire to burn them. They squeal like a pig about being butcher would been heard through the whole city if not for the other barrier I put into this place to not involved innocent bystander. Their scream stopped after a few minutes. It's seem that they fall unconscious from the pain.

I immediately pour the cold holy water I found in my dimension to them. They immediately wake up with another scream as the cold holy water add additional pain to their burned body while slowly healing their injuries only for it to have burn once again by the undying flame of darkness. As darkness seems to be a weakness to their kind.

"Ara~ra~? This is a surprise I never thought that you're very sadistic person Iva." Said Akeno while smile sadistically towards me and enter the church with Rias. I look towards them before silently store the Moon back to it's place.

I walk towards the underground where Asia been taken hostage. "Hey, don't ignore me! Where're you going?!" Pout Akeno as she never been ignored in the school before. "To save Asia." After I said that I climb down the stair and walk towards the area where I feel Asia and my brother.

I ignore the three devil that walk behind me in the underground there several rubble that fallen down from a fight. 'This unnatural crater on the ground must be...' I close my eyes to connect myself deeper to the nature and tried to sense the person who created this crater.

I open my eyes and walk to the sources. Under the rubles I found her, Koneko and I dug her unconscious form from underneath the rocks. "Ah! Koneko-chan!" Rias immediately run to me and take Koneko away.

"Hn. Calm down she just unconscious probably tired after fighting all the exorcists in this place." I said while dusting of my hand that covered by dust after picking Koneko. The devil sigh after they see that what I said is true.

"Let's hurry. My Nii-san is in the room right after this one." I run towards my brother direction with devils behind. I open the big double door and I saw my brother a red gauntlet with emerald green jewel embedded in it, punching the last fallen I able to sense, and she was the one that killed my brother.

After he manage to punch her, he immediately stagger back. I manage to catch him before he fall. "Good work Nii-san. I knew you could do it." I whisper to his ear. My brother give me a goofy grin before he remember something that make him suddenly saddened.

"What's wrong Nii-san?" I ask. "Asia... I'm failed to protect her Iva. She's dead." After saying that my brother cover his face with his hand to hide his tear. I look at Asia who laying on the ground near the altar. With my Senjutsu I can still feel her life force even just a tiny bit.

"Not yet, she still alive but we need to hurry. I need her Sacred Gear to complete what she loss. Where is it?" I look around the room to search the warm feeling that I always felt near Asia. "What! Ah! That fallen take it from Asia and then I saw her lifeless like that!" My brother snap out from his depression and proceed to glare at the fallen who lay on the ground while moaning in pain.

"I see." I immediately give my brother to Kiba while I flash step to the fallen. I yank her hair making her scream. I strangle her neck and force her back to lay on the ground while her face me face to face. She flinch and start to shake in fear after she saw my eyes.

She snap out her fear and started to scream again when I pin her arms, legs, and wing with the wind spear I used to shoot down her friend. I then sit on her while my hand glow with white light. She about to said something but I harden my hand that strangle her. "Shut up. I'm going to take back what you take from Asia."

After I said that I plunge my shining hand to her middle chest where I felt Asia's Sacred Gear. Beneath me the fallen started to shriek even louder while trying to flung me away from her but I already pin her body firmly to the ground. I continue with my work calmly with my stoic face ignoring the pain my heart felt when I saw my brother staring at me with frightful face.

The process extracting Asia's Sacred gear wasn't long only for a minute but I already left the fallen beneath me lay half conscious and drooling like a crazy person. I took the Twilight Healing and put it back to Asia and proceed to connect her life force that currently slowly flowing out from her body with my Senjutsu.

"Senjutsu!" Exclaim Rias surprised. Well, from what I heard from Koneko human in this world not supposed to able to use Senjutsu. But I'm not really a normal human to begin with. I ignored the buzzing behind me and concentrate with my current work. After I manage to connect the loss life force to her body I use the Senjutsu to gather the life force that have been leaking out because the forceful extraction.

It took me thirty minutes to completely return her back to normal and it's quite tiring as I can feel my body sweat. I'm really need to practice back my healing skill, it took longer than I thought.

"I'm done." I stand before unconscious Asia as I summon a towel from my poker dimension. "Asia!" My brother immediately run towards her and shook her body gently. Move away from them as the devil run past me to check on her wellbeing. I can sense Asia begun to awake by that shake and I see that I wasn't needed anymore. I left them to go back home. My brother can take care the rest.
