Summary
Shiina identifies as a self-proclaimed female ninja, engaging in combat using traditional Japanese weaponry like dual kodachi and shuriken. She wears the distinctive uniform of the SSS, accessorized with a long black scarf that obscures the lower half of her face and her neck. Her skirt features two short slits, a design choice likely intended to facilitate greater mobility during movement. Although she maintains a stoic and quiet exterior, Shiina has a deep affection for cute items, particularly stuffed animals. She possesses the ability to sense impending danger and is rigorous in her discipline, often prioritizing training over other obligations. Her regimen primarily involves balancing objects such as broomsticks, scissors, and mops on her fingertips, sometimes managing to balance one on each finger simultaneously while multitasking. Additionally, she frequently comments on her colleagues' behavior by stating, "how shallow-minded."
