She is a gorgeous mermaid idol of "Project Duo", and the heiress of the mermaid noble family "Nishiki". She is very prideful, hates losing to the extreme, and works to reach the top of all aspects with her own strength. One can see her fighting spirit from the fact that she never borrows the fame and power of her family in her idol activities.
To add with, she is well-known as an aristocratic girl before her debut. She works as a dazzlingly gorgeous idol to maintain her image, so that those who had known her before would not suffer from gap of recognition.
"A mature idol with bewitching charm". This is a genre still being developed in "Bermuda Triangle", waiting for someone to break new grounds. "Kazuha" is considered the leading person of this genre, and her eminence has triggered the debut of idols in the same genre, coming from a variety of production agencies.
Her idol activities have unearthed a brand new genre and livened up the atmosphere of the business. Is that the result of her talents in entrepreneurship inherited from her parents, or is that the fruit of mere coincidence...? Either way, she is destined to draw the world's attention as a lady who has shaken the business, now and in the future.
