A pack of monsters raided the small tranquil village where Asuka had spent her childhood. Lotar and his band who were chasing the pack arrived at the village, but they were just a little too late. They managed to save Asuka, but everyone else was slain. Asuka was raised by an associate of Lotar to learn to live alone and train in the way of the sword. Her wish to never see another orphan unsaved leads Asuka into the world in order to better herself. Asuka carries a pair of swords about her waist, which are made of a rare and luminous stone. Cold and decisive, Asuka is reserved and unfriendly before people, and remorseless before monsters. Her lightning-fast swords leave nothing but faint traces and dead bodies.
