Sora is a female Dachshund whose temperament defies common breed expectations. She radiates high energy and a hot-blooded nature instead of cuddliness, aligning with actual Dachshund traits despite her short-legged build. Her agility enables surprising bursts of speed and athleticism relative to her physique.

She possesses a tough, assertive demeanor often perceived as mean, creating a sharp counterpoint to the male Yorkshire Terrier, Sebastian. This establishes a masculine-feminine role reversal between them. Visually reinforcing their non-traditional gender expressions, Sora wears a blue collar while Sebastian sports a pink hair bow. Sora harbors unrequited romantic feelings for Sebastian.

A narrative instance reveals her emotional investment: Sora mistakenly believes Sebastian has feelings for another dog, Mametarou. She also objects to others using the nickname "Onamomi" for Sebastian, demonstrating protective concern. Their persistent contrast in behavior exemplifies the masculine girl/feminine boy trope.
