War, death, and destruction were the three best words to describe the Warring States Era. One clan in particular, the Chaos clan, took those three words as gospel and they too became one of the many clans to turn killing into an art. After a disastrous loss in a battle, the clan began to decline in power and status. Thankfully, when the clan heir, a genius of unparalleled proportions is born, the clan focuses all their resources into turning her into the best possible killing machine. When disaster strikes and the whole clan is slaughtered, the already powerful Chaos bloodlimit evolves, transforming the heir into what the clan always wanted, but not what the heir, now the last surviving member of her clan, wanted.
