"Looks like we're in trouble" A person said while revealing its appearance from the smoke of their attacks of zanpakuto, and in flash a zanpakuto was at her neck being hold by the person behind her. And the other captains of soul society appeared including Head captain Yamamoto, well except the captain of squad 12.

"Shinsui" the demon whispered as she narrow her eyes to the person who held the zanpakuto that was pointed at her neck.

"Kon'nichiwa (y/n)-chan~" Shunsui said in a sing song voice. Byakuya and Toshiro were a bit surprised of Shunsui and the other captains appearance in the battle.

"Bloom (z/n)" i mumble quietly, "hm?" Shunsui hummed leaning in to hear it clearly, but. A large blue fire with the shape of lotus engulf us both.

"Captain Shunsui!!!" The others and captains yelled in unison, worried for the squad 8th captain. Him slightly lose his grip on his zanpakuto, i took the chance and elbowed him on his stomach and he groaned backwards then i swung my zanpakuto behind me which he barely dodge cutting his hat and he distance himself from my zone that was covered by my blue flames.

"Oh my~ why did you distance yourself? Now i feel so lonely" the demon said with a sadistic smile and slowly revealing herself from her own blue flames.

Once she got out of her own flames, she saw the captains of each squad staring at her. "Oh~what a cold look i received" the demon snickered covering her mouth with her fingers. "I demand you to release ichigo and the others" Captain Jushiro said, lowering my arm to my side my eyes darkened, then they grabbed their own zanpakuto.

"Want me to release them? Sure if you defeat me that is!!" The demon yelled charging at them. (Y/n) body was covered by the white gloo-ey substance, and only half of her face wasn't.

Clashing sound was heard, every captain struggle on the demon's speed and agility to attack and dodge.

Fighting to all of the captain was just a waste of time, why can't i find something will worth my while? Dad didn't move even an inch on his position and just this captains are fighting with me.

Dismissing my thoughts as i landed a blow on captain soifon.

"Captain Jushiro!" Someone yelled behind me, snapping my head to the source i was met with an attack, dodging it by back flip.

"Hm? I didn't even know you can still move, Captain BYA-KU-YA" i said his name by syllables with an mocking smile on my face.

The attack that he send went towards captain Jushiro, who had absorbed by his one sword and fired an attack to the other sending it to me. My eyes widen slightly cause the attack was way more faster than the one who send it originally. The attack he send just barely graze my leg, and i barely dodge it, i took one step backwards only to widened my eyes as i heard a voice.

"Good luck, (y/n)-chan~" It said before elbowing me in the back and i landed to the ground with an explosion.

Hearing the explosion and smoke cover the area, shunsui, me and the other captains, stared down where the

(y/n) landed.

This information may be new to the other captains who hadn't met head captain Yamamoto's daughter and his wife few years ago, so this is quite shocking. But,the strength of the demon who's inside (y/n)-chan body was undescribable.

True, that demon was also the daughter of the Head Captain but was locked away inside the moment they were born. It's like 2 souls in one body, like ichigo but, naturally born. We haven't had any proper research on (Y/n) sister or i say demon, when the attack of aizen in soul society. So this info about her is unknown.

"Hahahaha" we all grip our zanpakuto thinking she'll attack in just a second but, she just stand in the ground looking at us.

"Right, the duo captain. How could it slip my mind?" She said, shaking her head sideways and her arms on her sides. I narrow my eyes at her, observing her movement, just in case.

Slowly, she walked a few steps forward towards her zanpakuto. She bent down about to grab it but, captain zaraki attacked behind her.

Sensing his thirst in battle, i manage to block his attack with my zanpakuto in the nick of time. "Well, well, well. Aren't you getting slow zarakai nii-san?" I said with a soft smile.

"Well, well ,well. Aren't you getting slow Zaraki nii-san?"

After those sentence left her lips, my eyes widen, because her tone was like its (y/n) itself and i distance myself a good 2 meters trying to comprehend if the real (y/n) is back. But, i was caught of guard when she attacked.

"Captain Zaraki!! Don't let your guard down!!" Captain Toshiro said.

"I know that! Dimwit!" I replied as the demon and i clashed our zanpakuto together causing a gush of wind. We did this countless of times until.

"Ablaze (z/n)" she mumble and her zanpakuto erupted in blue flames and in just a mere second she disappeared in front of me, until i felt a sudden slash behind me, causing me to fall forward. "Sleep for a while captain" i heard the demon voice before a sudden pain struck my neck. Slowly i was unconscious, her strength was too powerful that i can't withstand to stay awake.

The others yelled captain zaraki name after the demon hit his neck and force him to sleep.

In a sudden flash of time. The demon was surrounded by the other captains including Toshiro and Byakuya. The demon looked at them coldly and them not knowing she released ichigo and the others.

The demon snapped her fingers together and in an instant the other captain was tied in a blue chained rope. "Hehe what a cheap move" an alien like voice spoke in just a distance. Looking to the source it was captain mayuri of the squad 12.

"Why hello," was the demon reply, glaring immensely at the person head. "Captain Kurotsuchi Mayuri" she added but this time its in colder tone with a slight of hatred.
