Running back where (y/n) is, im sure she had already encountered one of the espada and in any moment now Aizen will appear. So i run at full speed, nearing to the 2 figures of people... Uh, delete that i mean 2 figure of souls fighting each other.

Seeing this situation i quickly hide behind a pole or wall i say, watching and waiting for the outcome of their fight.

"Toshiro, have you seen rukia?" Ichigo yelled looking for the certain person, "sorry but no," i replied not even looking at him and i felt him moved away as i blocked an attack from the espada and sending one which covered half of her legs.

"You better give up" i said in cold tone while panting slightly. "Hahaha! Dream on, i will never give up until our objective is done" she said, narrowing my eyes in confusion i asked, "what's your objective?" I said in a demanding tone. "Its related to the only bloodline of your head captain shigekuni" she said with a smirk, my eyes widen in realization, but before i could go and warn the others she blocked my way and attacked me with so much force that i was pushed backwards. '(Y/n) you must be warned!' I thought before fighting back.

Me and my brother was separated from the others by our fight with an espada and also after knowing what's their objective is, That's why were in a rush to end our battle and to find (y/n) immediately, but our opponents make it impossible to do it for they are stronger.

"Nii-san!" I yelled facing my bother as i saw my him getting pushed and a cut on his arm, "don't let your guard down!" Syazel yelled charging at me, i was slow to react and before i can turn and let my guard up, my opponent was about to stabbed me right in the chest. Closing my eyes i waited for the pain but i only heard a 'clank' noise, opening my eyes back, i was met with a black clothed person back, "ichigo?" I said unsure, "ichigo! How dare you interrupt!" Syazel that was my opponent yelled.

"Shut up! Is there even rules not to interrupt a fight if someone is about to die!?" Ichigo yelled back pushing Syazel backwards before facing me.

"So this is where you are. I've been looking for you" he said facing me and laying his zanpakuto at his shoulder. I was about to reply but when 'our' opponent is about to swing his sword at ichigo, my eyes widen "ichi-" i was cut off when he just turned around and block the attack and cutting one arm.

"Aghh!" The espada yelled in pain and agony as he hold his cut hand. I stare in awe before snapping back to reality, realizing the important situation.

"Ichigo! Nii-san we ha-" i was cut off again when my brother spoke "ichigo, rukia, you had to go and warn (y/n), now!" He yelled after the fight but his opponent back away little bit regaining back his stamina. "How about you? You're facing two strong espada" ichigo said worried. "You're underestimating me ichigo, and the important thing is we had to warn (y/n)" he said sternly which we nod our head before running back to the place where we were earlier.

The situation is starting to get out of hand, we are all occupied by the espada's and aizen didn't even moved an inch on his place, the espada's are more stronger than the last time we went and fight into the hueco mundo.

We can't find an opportunity to send message to the head captain, (y/n)'s life is at stake here, speaking of being occupied i can't see ichigo, rukia and captain byakuya here only, Matsumoto, lieutenant momo and captain Toshiro here and having trouble including me, my opponent are so annoying. 'One more thing shouldn't be Urahara is here helping and captain kurotsuchi could have send a back up.' I thought blocking an attack from my opponent.

"You better give up, we have planned this beforehand. So our attack can't be monitor by the squad 12." The espada that was my opponent said smirking before taking a glance at aizen.

"In your dreams!!" I yelled sending numerous attack non stop which caught him off guard. '(Y/n), aizen is after you'

"Come on, just leave already" i mumble nibbling my thumb and tapping my foot unconsciously, pleading that Aizen and his men to leave. Looking at (y/n)'s situation it is not good, (y/n) is panting heavily, muscles are tired and sweat rolling down her forehead.

"Like i said, you better give up already. You will never won" her opponent said with a his very own victory smirk. "Are you deaf? Like i said i will never EVER give up until i killed Azien!" (Y/n) yelled back her zanpakuto glowed, mumbling some word her zanpakuto turned into its shikai form. (An: the pic of it's shikai is at chapter 19)

After her zanpakuto turned into its shikai form, she mumbled a spell and used a kido restraining her enemy. Then not a minute longer (y/n) charge towards the espada, sending numerous powerful attack.

"Go gurl!!!" I whisper yelled pumping my hands to the air. (Y/n) attacked non stop but sadly her opponent broke free from her restraint and backed away healing itself. "You cowards!!" (Y/n) yelled, eyes looking at him menacingly. "*cough*" i froze hearing a cough behind me, slowly turning around, i was met with a broad chest. Raising my head i saw the face with a shoe sole imprinted on it.

"Good morning, grimmjow" i said smiling sheepishly, he grew a tck mark and draw his sword out. Knowing what he will do, i ran away from him and my hiding place and towards at the back of (y/n).

"Krystel-san? What are you doing here?"

(Y/n) asked not facing at me. "First, its chan and second a scary blue haired espada named grimmjow is after me!" I replied. "Find a place to hide, immediately" (y/n) said which i nod and run off.

'That little sh*t! How dare she threw a shoe at my face!!' I yelled inside my thought looking for the certain bluish-purple haired women.

"Why are you here?" I heard a voice behind me, turning around i saw sir Aizen. "Sir, I'm looking for the women you told me to kill" i replied, hiding my pissed self from him. "I will be one to kill her now, just distract her away from yamamoto's bloodline" Aizen said before disappearing into thin air. Hearing his reply i cursed numerous time but i can't ignore his order so i obliged.

Soon after walking , i saw the bluish purple haired women hiding behind a pole watching (y/n) fight, so i walk behind her a cough, i can see her tense up and slowly turning around then lifting her head she saw my face with the sole of her shoe printed on it. "Good morning, Grimmjow?" She said smiling sheepishly, i grew a tck mark on my head, clearly pissed before drawing my sword out then she run toward (y/n). I want to kill her noe but i can't disobey Aizen order which is pissing me off more. (Y/n) and my previous target talked a little then the bluish purple haired women run off away from them. Seeing this i disappear and appeared beside Aizen, nodding, cursing inside my head for not finishing it earlier.

After krystel-chan had gone off to a good distance, i stabbed (z/n) to the ground and kneel down before closing my eyes concentrating. "What the hell are you doing?" My opponent asked but i ignore him and started to mumble a spell which i remember that my mother teach back in my younger days, it appeared on my flashbacks when my memory is restored.

Second pass, the ground glow and a magic circle appeared in casing my me and my opponent. "W-what is this?" My opponent stuttered looking at his surroundings while i still continued to recite the spell then i heard him plead "s-stop it! No! S-stop. Ahhh!" He yelled, struggling to get out as he was eaten by the ground. Sighing in content, i stood up from my kneeling position and slice my skin dripping my blood to seal the magic circle i summoned.

"(Y/n)!!" I heard my name being called and turning around i saw krystel-chan running up to me with a wide smile etched on her face. Smiling slightly i watched her ran to me but my smile disappeared when i saw a glimpse of Aizen behind krystel.

"Krys-" before i can yell to warn her she was already stabbed in the chest, blood came out to the corner of her lips. I was frozen in the spot like my brain automatically shut down, eyes locked at the situation of my friend. Seeing these, the memory of my mother being stabbed like Krystel flooded my mind,playing like a broken disk.

Curse this day. At the thought of (y/n) winning over her enemy, i clearly forgot that Aizen is after me and (y/n).

"(Y/n)!!" I yelled coming out of my hiding spot and ran up to her with a bright wide smile, but. Before i could reached her , i was stabbed in the chest from behind.

"Ah, ah, ah. Can't let you loose, little girl" a very familiar voice that only belong to Aizen. "Heh, you may have killed me in this world but i know what is your end gonna be. I could turn it into a cruel one." I replied smirking, then he abruptly pulled his zanpakuto out from my chest which i screamed put of pain. Looking towards (y/n), she was frozen in place, eyes wide staring right into my place and situation.

"Aizen, you'll never succeed." I said before kneeling to the ground, hand gripping on my chest tightly before coughing. "I like to see you try" aizen said before disappearing into thin air. Collapsing to the ground i can feel (y/n) running up to me. 'Curse my memory, if i could have already said it to

(y/n) earlier, then i could be at home now.' I thought forcing my eyes to open still.

Just when aizen disappeared, my body moved on its own and run to krystel-chan body that was lying to the ground. A cold wind gust up to me and vision started to blur, desperate i reached krystel body and knelt down placing my hand to her chest trying to stop the blood, but it won't stop.

Krystel faced me and smiled,"d-don't c-c-cry" she said with a closed eye smile, bringing my hands to my face i felt myself actually crying. When did the last time i cried? When did the time i felt alone again? When did i forget my vengeance? When did the last time i felt pain? Anger?

"(Y/n) you better not betray soul society, and give.....you utmost trust to your companion......... and you'll see your.....mo-" Krystel didn't finished her sentence as her hand went limp, eye closed and her breath stop. Slowly her body glowed and little by little her body fade like ash drifted by the wind, leaving me alone again.

"Ahhh!!!!" I screamed in, pain and agony with tears rushing down on my cheeks, gripping my hair and then my vision became black.

When the time (y/n) loose control of her body, a white like substance turned into a mask like form on her face covering half of her face, the old (e/c) eyes turned into a deadly yellow as her scream turned into a hollow scream, catching every soul reaper and espada attention and stopping them from their fights.

Slowly, (y/n) body was now covered into the white dark skull attached to her body. A figure of a demon.

"My, my, my. It look like aizen had made its move and had woken up a demon" i said leaving my hiding place after witnessing the actual event.

"Sh"t!! Were too late!" I heard ichigo yell behind turning around i look at him then back to my opponent. "Looks like sir Aizen did it" he said looking at me with a smirk and disappeared along with the other espada's then appearing at the opened sky behind aizen.

Suddenly, we felt a very strong spiritual pressure it even rivals the spiritual pressure of the head captain, but. It may been greater than the head captain itself. My breathing is getting heavy and bullet of sweat covering our forehead. In a minute of thinking, all of our eyes widen in realization. "Where's (y/n)!?" I yelled which snapped their attention at me.

Then captain kuchiki appeared in the same condition as we were. We barely can stand up. With a gust of wind, a familiar figure appeared in front of us.

"Good luck soul reapers, the (y/n) you knew are now gone. The person in front of us now is a demon. She'll attack everyone with no regret, i want to use it as my weapon but, it's hard to tame" aizen said, slightly breathing heavily but his espada is barely standing up. "Your death is soon to come, by the hands of the demon who lives inside the soul you called (y/n)" with that Aizen and his espada entered the open sky.

The soul reapers stood on their spot shock. Shock from the information Aizen said and the fact that the (y/n) body was in front of them and a silky like mask is slowly covering her face. 'How come? How come head captain didn't say anything about this?' The two captains thought in the same time.

Krystel lifeless body had been completely fade away, turning it into a part of the wind but it still has the mind of krystel.

Im in my lab staring into my computer for the collected data to create a poison that captain Unohana can't analyze, until something pop up on the screen (an: yeah im in control even im dead so shh) curios, i checked it and an image appeared.

My eyes widen as a letter was presented from the image below. It says:

"I know captain kurotsuchi was reading this, (y/n) inner hollow had been released and turned into a demon, occupying (y/n) body.

Truly yours

~krystel,

(An: he he, just addition)

Not a minute longer, i dashed out of the lab and flash stepped towards the squad 1 barracks.

.....

"Head captain!!" I yelled barging into his office without permission. His attention and his lieutenant faced me, "what is it?" Head captain asked and a slight surprise expression.

"Head captain, the worst had come"
