Kunoichi was celebrating the victory at Osaka campaign, much like everyone else. However in addition to being happy about the victory, she also felt there was something that needed to be let go from deep inside her heart. So she left the celebration trying her best not to be seen, she walked around the palace and then out into the palace gardens.

The Osaka victory is celebrated tonight
Not a sorrow to be seen
A kingdom of Unification
And it looks like I'm the queen

These emotions are a swirling storm inside
Couldn't keep them in, heaven knows I tried
Don't let them in, don't let them see
Be the good Shinobi you always have to be
Conceal them, don't feel, don't let them know
Well, now they know

Let it go, let it go
Can't hold it back anymore
Let it show, let it show
Turn away and slam the door
I don't care what the master says
Let my heart go on
The rules never bothered me anyway

It's funny how some kindness melts a ninja's heart
And regardless of people say he and I, will never, ever part!
It's time to see what I can do
To test the limits and break through
No right, no wrong, no rules for me
I'm free!~

Kunoichi began to run around in Pure happiness and dance in sync with the flower petals.

Let it go, let it go
I am one with the wind and sky
Let them show, let them show
You'll never see me cry
Here I stand and here I'll stay
Let the my heart go on...

My Love for My lord Yukimura flurries through the air and in the ground
My soul is spiraling in Sakura Petals all around
And one thought warms me like a fiery blast
I'm never going back
The past is in the past!~

At that she removed the dagger pouch from where she kept them around her thigh and threw them off to the side. It was almost like magic but the sakura petals that fell from the cherry blossom trees surrounded her and her Usual Ninja garb transformed into an Elaborate Pink Kimono with the Sanada Clan crest at the bottom of the skirt.

Let it go, let it go
And I'll rise like the break of dawn
Let it go, let it go
That perfect Shinobi's gone
Here I stand in the light of day
Let my heart go on!
The rules never bothered me anyway!~
