From the description on Team NINJA's YouTube video of the trailer:
Honoka Profile]
Having been raised all her life by her gentle and loving grandmother, Honoka is a sweet, easygoing kind of girl... but when she sees a fight, she cannot contain her excitement, nor the mysterious power surging within her. The truth is, Honoka has this strange knack for instantly learning any fighting move she sees. She's never told anyone about her power, but has been itching to test it out in secret...
[Fighting Style]
Honoka takes her favorite moves copied from various sources and fighting styles, and combines them into a unique style which she calls "Honoka Fu". Since her physical condition is that of an average teenage girl, her moves may not always have the same power or reach as the fighter she learned them from. In her Hissatsu-no-Kamae stance, however, she is imbued with an unbelievable strength and becomes capable of techniques she has never seen from any other fighter.
