"Head captain, The worst had come" when captain kurotsuchi said that, my eyes widen for he only meant one thing.

'My daughter'

That came to my mind as i stand up from my seat. "Send all the captain and their lieutenants to the world of the living!" I yelled which he only nod and walk out of my office.

"Head captain, what will you do now?" My lieutenant Chōjiro said looking at me in worry, "let's just hope everything will go well" i replied gripping my staff.

Announcement was carried on and catches the captains attention.

On the squad 11 barracks

"Ken-chan!!" Yachiru yelled slight worry before jumping on her captain shoulder. "I know yachiru" captain zaraki replied "this means a great fight!" He yelled with a grin before jumping roof to roof heading towards the Hogyoku mountain.

We are are all frozen in our spot as we stared (y/n) who's in front of us with a scary appearance, then she smiled.

"Heh heh, so this is how it feels outside than the girls inner body" (y/n) said, or should i say the demon inside (y/n).

"Who the hell are you?" Toshiro asked pointing his zanpakuto at the demon same as the others preparing for the fight to come.

"Hm? Who i am? Well, I'm the one they call a demon who was born in the same day, same place, same parents as little o'l (y/n), i wasn't actually given a name" the demon replied but whispered the last sentence and started bringing out her sword/zanpakuto from the thin air and a blue fire surrounding the zanpakuto as the demon grip the hilt.

The captains and the soul reapers stiffened, "this wasn't possible" Toshiro mumbled to himself as they ready for an attack. The demon who know what their plan smiled. "Everyone n-" Byakuya and Toshiro was cut off as the demon disappeared in front of them.

"Wh-where is she!?" Ichigo yelled as they look everywhere.

Suddenly, a blue fire balls was shot from above them which they barely dodge it and looked up for the demon only met by more fire balls on their way.

"Hyōrinmarou!!" Captain of the squad 10 Toshiro Hitsugaya yelled and then a ice dragon came stopping the blue fire balls and exploded after they collide. "Hm? So your the ice short captain?" The demon said in a innocent tone but a cold look on her face.

"Im not short!!" Toshiro yelled, even in times of dangerous moment, the height of the squad 10 captain is unavoidable issue.

"Oh come on. Face the reality, your not even on the average height" the demon said on the matter-of-fact tone before sending another horde of blue fire balls. This time they work together and stopped it. Matsumoto stood on her ground focusing to land an attack to the demon but failed as one of the blue fire balls exploded behind her back. Time passes the soul reapers didn't even know that they were cornered in circle, "h-how did she cornered us?" Momo stuttered as they all became alert.

Once again, the demon appeared in front of them. "Hm you still had strength huh? I think its time to kill you all" the demon said shadow covering her face as she held her zanpakuto above her head, strong spiritual pressure enveloping the sky as she looked at them with blood lust.

Right when she dashed towards the soul reapers, they move their zanpakuto in front of them waiting for the attack.

The demon had silently appeared in their back ready and about to attack, but a blue arrow flew between them stopping the demon from attacking and let out 'tch'. The soul reapers look at their back only to see the actual demon who their fighting.

"Care if we join the fun?" A voice asked, and looking at the source, they saw Uryu ishida, Inoue and chad flying to the sky with the help of Inoue.

"Another people huh?" The demon said backing up a good distance.

'This is unusual' i thought as i narrow my eyes towards the demon who's occupying the body of (y/n).

"Uryu, any plan you have?" Ichigo whispered behind me, "to tell the truth, i don't" i whispered back readying my arrow.

"I let you live long enough" the demon said, and we could already feel the tremendous blood lust coming from her as her zanpakuto was slowly turning into a crimson blood color instead of a crystal blue color that i saw earlier.

"I sense something different from you" i spoke catching their attention including the demon, "you are a demon who can kill all of us in a blink of an eye, but. I know there's something you desire" i added, looking straight into the demons eyes, looking for a certain something. This moment ichigo is a slight confuse of what uryu meant and what the demon reaction.

"Something i desire~? Is to kill everyone on my sight and on my way!!" The demon yelled manically smiling as she disappeared in our sight once more, then a countless red fire balls was fired on pur side and above us. 'Something is strange' ichigo thought narrowing his eyes.

"Scatter, Zenbonzakura"

"Hyōrinmarou!"

"Getsuga tenshio!"

"First dance: frozen lotus(?) (An: i forgot rukia move😅don't kill me!!!)

"Howl, Haineko!"

"Zabimaru"

Etc. Cause I forgot momo's move

It took all our effort just to block the attack, but luck are not on our side as we receive a damage.

"Tsk, tsk, tsk. Your just digging your grave. Hahahaha!" The demon laughed as she send more attack on our way.

"Lord aizen, what will you do if the demon had successfully killed the soul reapers and come to us next?" Ulquiora my trusted right hand asked.

I can only smirk as i we watch the fight between the soul reapers and the demon who occupy the body of the old man heir before i answer Ulquiora question "we can use the power of Hogyoku against her" i said, but something is bothering me that i can't pin point. True, the demon inside the daughter of head captain Yamamoto isn't easy to tame. I only learned about the demon residing (y/n) body when i came into the squad 12 barracks when I'm still a lieutenant hundred years ago to look for something but, i encountered a file that tells all about (y/n) that caught my attention and i use it on my advantage.

This feeling of something wrong cause me to frown, 'let's just see the outcome' i thought as i focused my eyes on the screen.

The soul reapers and the demon stare at each other, waiting for the demon next attack as their sense was heightened.

"Looks like no time to hold back" the demon snicker as she disappeared on their sight once again. The soul reapers including chad, inoue and uryu thought that a red fire ball will be fired at them again and became prepared, but. Unbeknownst to them it wasn't a fire ball this time but it was the zanpakuto itself.

"Gahh!!" Renji groan in pain as blood started to trickle down his stomach. "Renji!" Ichigo and rukia yelled in worry.

The fight continued for a while as the demon disappeared before appearing and giving damage to each person.

'This has no end!' I yelled inside my head as i tried to follow the demon's movement with my eyes and i attack but, before i could release an attack i was already hit by her zanpakuto.

"PATHETIC!!" The demon said laughing maniacally, then she click/snap(?) her fingers together, the others were trapped into a cube like cage leaving me and captain byakuya free.

Ichigo tried to break the cage where they were trapped but it backfired as they got electrified, Chad and Uryu stopped ichigo and started to think a way, while Inoue heal renji.

"What are you planning?" Byakuya asked as he narrow his eye at her. "What's the fun if there's no audience, right? Don't worry I'll end your life in a second!" The demon yelled before dashing towards us. "Ban-kai!" I yelled as my spiritual pressure increases and i was covered in ice with a figure of dragon enveloping my body through my zanpakuto. Then our zanpakuto clashed together, we pulled away and disappear from each other sight before appearing and sword clash once again.

V

This fight was thrilling, the person who

(y/n) treasured most in her life, was my opponent for the mean time, Tōshirō Hitsugaya.

"Why don't you fight us for real!" He yelled as we clashed our zanpakuto together once again. "Saving my energy for the biggest moment to end everyone" i replied menacingly, i was too focused on my upper body and this made Toshiro to push me backwards, i was caught off guard as Toshiro moved and i saw Byakuya behind him and fired an attack at me.

I was thrown backwards from the impact and i was facing up the sky, then Toshiro appeared in front of me also sending an attack downward, i used mine and (y/n) zanpakuto, (z/n) stopping the attack but, i was pushed down and have a strong impact to the ground, causing to smoke.

"Do you think they can defeat her?" Inoue ask, feeling worry for the captains after she healed renji.

"I'm not sure, Inoue" uryu said adjusting his eye glass. "What will we do now?" Rukia asked facing ichigo, "we'll bust out!" Ichigo yelled only to receive a smack on the head by rukia,

"Baka! Do You Remember When You Try To Bust Us Out!!" Rukia and the others yelled with a tck mark on their head except chad who is calm.

"Alright, then what will we do?" Ichigo said rubbing his head where the smack landed.

Suddenly, the cage where they are moved forward, "w-whats going on?" Inoue ask standing up, then they saw a smoke with the two captains standing in the sky looking down where the smoke is.

"Hm? How did you moved the cage?" Byakuya asked curiously. "It move in its own captain!" Renji yelled, sitting up. The captain eyes widen in realization hit them as they hear a familiar laugh. "Hahaha! What a good exercise!" The familiar figure said stretching in the smoke before flying up, and in a blink of an eye the demon was in front of captain Toshiro.

It was late when Toshiro knew that the demon was in front of him when he has hit and slashed by the demon zanpakuto, then she disappeared again. Captain byakuya was alarmed and try to sense the demon's spiritual pressure but he can't, "behind you captain~" a teasing voice came to byakuya's ear, and his eyes widen, before he can turn around he was already slash and hit by her.

The demon backed by a good 5 feet, her blood lust increasing as she saw the blood from the two captains.

"Sh*t" Toshiro (never) cursed as he held his bloodied chest before they both cough up blood. "She's stronger than i thought" Byakuya and Toshiro mumble panting for air as they apply pressure on their wound.

"Say your last prayer!!" The demon shout and dashed towards the two weakened captain, but. A sword block her way and they clashed their zanpakuto together, with the force of the demon the one who block was pushed backwards.

"Looks like we're in trouble"
