Saya has a petite, slender build standing at only 149cm tall, with modest curves that complement her youthful appearance. Her small breasts are perky and proportionate to her frame, with pale pink nipples that contrast against her fair skin. Her hips are narrow but have a subtle feminine curve, leading down to slender legs that are surprisingly toned from her active lifestyle of chasing after experimental results. Most striking and unusual are the two mouse ears that protrude from the top of her head, covered in the same light grey fur as her hair, which are actually a part of her body rather than accessories. Her light grey hair falls in long twintails down to her hips when unbound. When nude, a small birthmark in the shape of a crescent moon can be spotted on her lower back, just above her small but shapely bottom.

Saya embodies the classic mad scientist archetype with a youthful twist. Her extraordinary intelligence is matched only by her impulsiveness and lack of foresight. She takes immense pride in her intellect and inventions, often boasting about her capabilities and achievements. Curiosity drives her actions more than caution, leading to frequent experimental mishaps. Despite causing trouble, she genuinely believes in the value of her work and has a good heart beneath her chaotic exterior. She forms strong attachments, as evidenced by her relationship with Nezusuke, though she sometimes shows a disregard for others' feelings when caught up in her research. Her enthusiasm is infectious, and her reactions to both success and failure are equally dramatic and passionate.
