Synopsis
My name is Nariyoshi Inusuke. The best brain hacker in the world. Brain hack is to invade the target brain through a bioimplant and deprive the brain of administrator authority. Once you've deprived you of administrator privileges, you have full control over that person-in a pre-modern way, you can be a slave.

I've been active since the dawn of Brain Hack, and I'm afraid in that world, but ... at that time, I was just a tiny junior high school boy who hadn't even installed Partizan yet.
