Ichimatsu Mitsuru spends her days studying.
Of course on schoolwork, English, French, and Italian,
On top of that she even works her body to the bone learning her fathers school of martial arts.

She does all that's for the sake of her father who solely relies on her since Mitsuru's mother passed away when she was a child.

It's not like her father is by her side always though, he went to work as the succesor of her Italian mother's parent's business.

Some day she too will do the job her mother and father once did,
taking those feeling to heart she endures each day without them.

One day her father returns home after a long while.
During dinner together he tells boastful story's and afterwords he happily spars with Mitsuru.
However suddenly her father faints.
Until her father Seigai's condition recovers he decides to leave his job up to Mitsuru.

He does it for the opening moves of the future, and even more so for the sake of his beloved daughter.
Mitsuru is determined. For the sake of her father she will do a fine job.

In front of that passionate girl, her best friend tells her,
"Seigai's workplace is full of guys isn't it? They won't underestamate you even though you're a woman right?

Mitsuru suddenly falls silent.
She takes that reliable friends suggestion to heart.

Mitsuru dresses up in the men's clothes that her friend prepares for her and wraps up her righteous yet inconsistent justice into the palm of her hand.

She walks into the airport with her boots lightly echoing.
Ahead lies her work, what kind of contradiction awaits her there.
