Unexpected destiny( Fairy tail × Bleach)

Prologue

Koori's pov.

We were fighting against the soul reapers especially that half-human soul reaper, Ichigo Kurosaki. As I heard from my brother, he can turn into a hollow. I also heard that there are more humans who have powers but they are no threat to us. As for now, I was fighting a captain-level soul reaper. He had long raven hair and he also had some white hair clips on it. I shot a green cero at him but he dodged using his shunpo. This guy was fast. I drew my zanpakuto and teleported behind him using sonido. I tried to slice him but he blocked. His senses are not to be underestimated. We clashed a few times before he activated his shikai. His sword turned into thousands of cherry petals and started attacking me. I dodged most of them but he still managed to scratch my left arm.

"You managed to scratch me, captain." I said with my usual monotone. "But that's not enough to stop me. Before we continue, can I know your name? I am Koori Schiffer, espada number 4."

"I am Byakuya Kuchiki, captain of the 6th division." He said and pointed his sword downwards. What surprised me was that he let go of his sword. 'Is he insane?' But the sword went into the ground like it was water. The sword disappeared and two lines of blades appeared on either side of him like lampposts.

"Bankai. Senbonzakura kageyoshi." He said and the blade turned into more cherry petals. Then, they started attacking me. 'I won't be able to dodge them all. I guess I'll have to use that.'

I held my sword upright and said, "Blind them, Ligero." My sword disappeared and turned into small blades of light. My appearance doesn't change much. My eye colour changed from green to deep yellow and my hair grew a bit longer and the tips turned into white. I used my light blades to block all of his blades. Then, his petals disappeared. I could see surprise in his eyes. I sent more blades in his direction but he kept dodging using flash step. He also summoned more blades. I tried predicting his move and waited for an opening. I pointed my index finger at him and shot a green cero and hit his left shoulder.

"Tired already, soul reaper?" I asked him with my usual emotionless tone.

"Senkai. Senbonzakura kageyoshi." He said and pink light engulfed both of us and thousands of pink swords surround us, isolating us from the outside. I was surprised but I kept my composure.

"This is the true form of senbonzakura. Don't worry. They won't attack you all at once." He said and a sword appeared in his hand. He disappeared from my sight and appeared behind me. I barely blocked him with my sword.

We clashed our swords for a few times. I noticed he got faster and I could barely blocked his movement.

"I noticed you got faster or it was me who got slower?" I asked him.

"The latter. You're the first one who's able to notice that."

"I'll take that as a compliment." I said and held my sword with my right hand pointing it at 45 degrees. If you're wondering, I prefer holding with one hand because I can use the other to fire a cero. Just like my brother. This time I used sonido to teleport behind him but to my surprise, he disappeared as well and suddenly appeared behind me. I couldn't block him. He slashed my back but thanks to my hierro that wasn't too deep.

"I have to admit you're strong, captain." I said.

"You're not too bad yourself either." He said and pointed his sword upwards." Scatter. Senbonzakura." The blades started to attack me again. I didn't have enough time to react. They slashed me all over the body but wasn't too deep. The major ones were the one on my back and the other across my torso. I was panting and so was he.

"Koori, come here." Lord Aizen called me. I glared at the soul reaper captain before teleporting to Lord Aizen.

"Yes, Aizen-sama. What can I do for you?" I asked him.

"You're useless. You can't even defeat a captain. I don't need you anymore." He said and drew out his zanpakuto. I was confused. He tried to stab me but I managed to dodge due to my quick reflexes but he stabbed my left shoulder.

"Why? Why are you doing this?" I asked him with my eyes wide.

"Bakudo #81: Splitting void." He said and a portal appeared. He then shoved me inside.

"Sister!" I heard Ulquiorra screaming while reaching for my hand. I tried to catch but it was too late.

'Why, Aizen-sama? You saved me. You saved me from my horrible life. You gave me powers and home. My life was getting better again. I got to meet my brother again and also got some friends. I served you. I completed the missions even if I have to risk my life. But why? Why do you have to betray me? You promised me you would give me anything I want if I help you. And I did everything you asked. I obeyed your orders. But now, you want to get rid of me. But now all I can hope is my brother to be safe. Please spare his life, Lord Aizen. Please don't hurt him.' That was my last thought before I was engulfed in darkness.

Ichigo's pov.

I saw Aizen shoving his own espada into a portal. 'Is he insane? That was his espada. How could he?' Ulquiorra tried reaching for her but it was too late. The portal has already disappeared. She will never come back again. Then, Ulquiorra started fighting Aizen and it was all a mess. Surprisingly, all the espada stood on Ulquiorra's side.

"I will kill you, Aizen. For killing my sister." He said to Aizen.

"Really? We'll see about that." Aizen said with a smirk.
