Y/n's pov:
Y/n: now the...you creeps are gonna get whats coming for, besides its not my first time facing monsters so.
Y/n: bring it! - begins charging towards those two monsters and which cut off one of there arms and dodge another attack and counter it by swing release energy slash which the monster block - is that all?
I jinx myself and saw more monsters coming out and was surrounded some which have blades with two feet, others humanoids and all try to attack me but i only use one arm to block all those attacks as if i was humilliate them while smirking with confidence.
Y/n: is that all? I'll take you all on. - says gribing the zanpakuto which electricity coming out and say those two words - BAN......KAI!!
Note: a Bankai without a pause is not a bankai xD bleach rule 101
When i shouted a huge energy release push away few of them at same time by accident some people can sense my power, anyways i wear a bankai form identical of my dads before new zanpakuto and my big sword was now a jet-black sword and swing a bit release a black getsuga.
Bankai: " Tensa zangetsu"
Y/n: Getsuga . . . tensho! - unleashes a huge strong swing vertical eliminated all those monsters one shot them which lets a huge blast, after that blast i blink few times realise what i did- uh-oh i might have over done it a bit ehehehe...
Y/n's mind:( yet strange. . . . why or how i know his name? Did this zanpakuto or zangetsu . . . connected old memories??)
???: oi you intruder, what are you doing here in lady kagura's shrine!?
I turn around and saw two female figures, one is chewing gum while accompany a little girl with strange eyes, wait how can they see me?? I remember that rukia say something about those who have spirit pressured can see that no normal human can't and Yet those two can see me??
???: well? I say identify yourself, or i should i make you answer in kagura's-
???: don't worry naraku, let me handle it
Naraku: k-kagura-sama?
Y/n: your this kagura right? But your just a small girl.
Naraku: you dare disrespect kagura-sama!
Old man zangetsu: " be careful, although she may be small but i sense a incredible power that must not underestimated" - says telepathically to Y/n-
Y/n: but seriously, im not looking for trouble so i just take my leave and-
Kagura: - smiles and pulls out a piece of candy and eats it making her body change for completly while release huge energy making smoke come out -
Y/n: - i cover my face after the pressured of unbelievable power and once ended i look at the kagura little but instead saw the a female with long hair with same eyes -
