More precisely, she was connected to the building’s security cameras with a long, thin cable stretching from the fake eye built into her eyepatch. Of course, she had no interest in the building itself; the camera was just a gateway. Through it she entered the security company’s network and went through the footage archives to see if Hamazura was in them.

Her flesh-and-blood brain was directly connected to the mechanical eye, but there was additional meaning there.

It meant she could directly receive information from the machine.

Of course, it had to be translated into information a human could detect, so it wasn’t perfect and she mostly relied on images through the fake eye’s system. However, she could do things that were impossible with a normal interface.

While an image search was being carried out at high speed behind her forehead, Mugino used her spare hand to operate her cell phone.
