She is voiced by Saki Ogasawara in the Japanese version, and by Jad Saxton in the English version.
Itsuka is a medium-height girl with medium-length ginger hair and teal eyes, with notably thick upper eyelashes and visible lower ones. She usually wears her hair in a ponytail on the left side and has three clumps of hair sticking up from her head. Her bangs are split so one is on the right, middle, and left sides of her face.
Itsuka's hero costume is a teal knee-length qipao, and she wears a double-breasted black corset over it. Underneath this, she wears short black sports pants and a small brown belt with a gold buckle over her thigh. Another belt is worn low on her hips and has a satchel attached to the back. A thin black domino mask is worn around her eyes. Her shoes are grey-navy with white heels and trim. The vamps in her boots are filled with white slips.
Her winter hero costume has a minor change being that she switches her qipao out for one with shoulder-length sleeves.
Itsuka is a very high-spirited, thoughtful, and well-matured girl that knows what's best for others, including with her discipline towards her classmates (Mostly towards Monoma) in making sure she leads them well and have a more friendly relationship with the students in Class 1-A. She's not one to hesitate and criticize of what others were doing is not right and sometimes she needs to make sure it doesn't happen, like when she karate chops Monoma on his neck whenever he antagonizes or threatens the Students of Class 1-A.
- Kendo shares many similarities with Momo Yaoyorozu that considers her a counterpart:
- Both of them are beautiful and very strategic in battle.
- Both were voted to being officers of their respective classes (the only difference was that Kendo was voted as the representative while Momo was voted as the Vice president of the class).
