Stryka was a centaurian demon, one of the demons that would become the inhabitants of the Dimension of Pain. She was counted by some of them as their skilled warrior at the time the demons prevailed over the original inhabitants of that dimension and the Demon King defeated the Goddess of Goodness. She was also eaten by her mother after that battle. She probably had multiple siblings, but the only one known, who has actually survived uneaten to the present day, is her younger sister Tryka.
