The blue monkey that dwells inside Kei's sword. Actually he is a part of Youko's conscience who is constantly teasing her.    Aozaru (青猿, Aozaru?) is the physical manifestation of the sentient spirit of the scabbard of the Suigūtō (the Water Monkey Sword). The sword is a royal treasure to the kingdom of Kei and can only be wielded by the kingdom's rightful ruler - as such, Youko is the only one who can draw the sword from its sheath. The sword was forged from a water demon that a previous great ruler of Kei had defeated while the scabbard was created from a long-tailed monkey demon. From the scabbard hangs a large jewel that can heal the one who holds it.    The sword is not only capable of killing demons and sages and breaking substances like metal chains, but is also capable of presenting visions of the past, future, and things in the distance. The sword and scabbard must be kept together, otherwise the phantasms of the sword appear unchecked while the spirit of the scabbard is free to act as it wishes. When Youko loses the scabbard, it appears in the form of Aozaru, the blue monkey, and taunts her with her doubts while the sword presents her with visions of things she does not wish to see. Eventually, Youko, overcoming her own doubts, kills the monkey and picks up the dead scabbard. Because she has killed Aozaru, the sword can be drawn from the sheath by anyone, though it can be wielded effectively only by Youko.    Source: Wikipedia

Nakajima Youko is your average somewhat timid high school student. One day, a strange man named Keiki appears before her, swearing allegiance. Before she could properly register what was happening, demon-like creatures attack Youko and her friends, after which they are pulled into a different world. A world unlike what she has ever known. Separated from Keiki, Youko and her friends must do whatever they can if they wish to survive in this new world.
