✦
Nira is generally a morally gray character. She comes from a noble family, but now works independently, with no organization or group to answer to.
✦
What truly sets her apart is the curse she has carried since the age of ten.
≣ The curse becomes stronger when she is caught in complicated situations, especially when her emotions and logic come into conflict.
✦
The only way to temporarily suppress the curse is to cut a portion of her hair. If she doesn't, its effects gradually become uncontrollable.
≣ That is why Nira never lets her hair grow past a certain length.
