Saya Kusanagi


She is a female cyborg warrior fighting in the virtual world in a near-future Earth.
She fights with KUSANAGI, an heirloom sword inherited over generations of the Kusanagi family. When she equips KUSANAGI, she accelerates in battle. Her favorite phrase is “You are so slow that you look motionless.”
