Nightshade is a 6-year-old child who became an entity of people's nightmares. He acts childish, adorable, kind and innocent, but in reality he has seen everyone's nightmares, even watching some people commit suicide. Nightshade was given a needle and a golden thread, with which he could weave dreams for those suffering from nightmares, but, he could never weave a dream for himself. He doesn't remember his past life, so he chose the name Nightshade, which he remembers was his favourite flower.
