Amasawa, Yuuko

天沢勇子

Known by the nickname Isako, an alternative reading of Yūko meaning "brave girl", Yūko Amasawa is a formidable hacker classified as an "encoder". She infiltrates the code and infrastructure of the virtual world itself to acquire power and metabugs. Rumors suggest she has familial connections to an AR technology company. Isako utilizes a Brain-Computer Interface to interact with the virtual world—a capability allegedly concealed deep within the hardware of AR visors and eyeglasses. She relentlessly pursues a specific type of "living metabug" virus that contains a keyhole in its body. On the surface, Isako appears extremely arrogant and unsociable, viewing human relationships strictly as hierarchies of power.
