Shizuka has chest length, straight and shiny dark mocha hair along with blunt bangs at the front that barely covers her left eye, and she also has forest green eyes and sizable breasts; she usually wears strapless bras. She wears red frameless magic reading glasses. She is quite tall for a Japanese girl her age. One of Shizuka's physical features which are often shown is her lips, which have a shiny pink appearance. Shizuka mostly wears her school uniform; however she does change her attire when not at school. At Chiaki Kondō's friend's, Erin Ruff, she wore her pajamas which consisted of a tight, orange tank top and white panties, and she also puts her hair up into a single ponytail. During Celestial and Phantom hunting missions, her clothing changes to female battle boots with heels, long lace black stockings, urban camo gloves, her school uniform top, a skirt that shows the string of her thong and her entire right thigh, a white lacey bra, and a special belt to hold her phone.
When it comes to the person who follows the rules and imposes them, that is Shizuka. She is relatively strict, because she is aware of her position as the Student Council President and therefore she is the model for her fellow students. However, she often felt a great shame when in some embarrassing topics and situations, especially when someone looks at her oddly. She is shy with boys and even says she does not like men. That's because Shizuka is severely androphobic, hates and fears them.
- Shizuka worked part-time in a maid cafe one summer, but her mom found out, and she had to quit after a week.
