She has long curly white hair, blue eyes and white wings. She is pretty enough to make Naga blush.
- Immortality: Bidan's species is immortal, unable to get sick, injured, or get killed. Any physical wounds their species receives will be restored immediately, along with severed body parts attaching themselves back together.
- Healing: Bidan, along with her brothers, possesses more powerful healing abilities than any other healer in SPOON. This is due to the siblings being immortal, meaning the life energy required for healing never decreases.
