Katsuragi is a third-year student at Hanzō National Academy, recognizable by her blonde hair tied with a blue headband. She possesses a notable bust size and frequently wears her uniform open, revealing her midriff and chest during Shinobi Transformation; she utilizes a breast harness for coverage despite claims of going without undergarments.

Her personality blends exuberance with high emotional expressiveness, often leading to tearful outbursts. She habitually sexually harasses female classmates, particularly groping Asuka and Ikaruga, stating she enjoys their reactions and the softness of their breasts. Yet, she exhibits significant discomfort and embarrassment, sometimes nearly crying, when others touch her. Underlying this behavior is an elder-sister-like demeanor that fosters camaraderie among her peers.

Abandoned early by her shinobi parents after they became renegades to protect her following a failed mission, Katsuragi became a shinobi herself to atone for their actions and seek reunion. During her first year, she persistently befriended the initially aloof Ikaruga, eventually helping her overcome personal struggles through combat and mutual understanding. In her second year, she and Ikaruga mentored Asuka, solidifying their trio.

In combat, Katsuragi employs a unique kicking style, favoring leg techniques over weapons while using wind-controlling boots inherited from her parents. Her dynamic moves frequently result in panty shots, consistent with her uninhibited nature. These boots form part of a weapon set linked to Yozakura's gauntlets; both items originated from Katsuragi's parents, who trained Kurokage before their deaths.

Her core traits persist across spin-offs. In *Bon Appétit!*, she wins a cooking competition for a wish-granting scroll, initially intending to create a "hooters harem." Upon victory, she reflects on life's challenges, rejects escapism, and acknowledges perseverance leads to true happiness, while still maintaining her comedic "jiggle" mantra. In *Estival Versus - Festival Eve Full of Swimsuits*, she appears at the spa resort gathering but plays no significant role in the water battle or Kuroku conflict.

Originally planned as the Hanzō team's protagonist, developers replaced her with Asuka due to similarities with Hakufu Sonsaku from *Ikki Tousen*, seeking to avoid potential legal issues, though she remains a popular figure.
