Is Togusa a cyborg in GITS:Arise?
He's got a "walkie-talkie" in his brain. I'm not sure, but I suspect his brain is fully cyberized as part of his job's requirements. You would certainly not want to be that one idiot shouting tactical information out loud while the rest are communicating almost instantly via a secured wireless connection.

In the GITS:SAC series when he's in court, his teammates find out they can't communicate with Togusa because he turned off that module, which means he already had it at that time. SAC happens later than Arise on the GITS timeline, so he probably got it installed somewhere at the start of his career as a cop.
