Ooooooh, that abbreviation is dangerous when we have TSUneyo and TSUkasa. Tsuneyo's father being the god of wires is a popular theor, but Tsukasa's father being the god of wires is out of left field.
The theory gained a lot of traction when Akira and Yuki tried to go upstairs and check in on him during that one power outage and things started to get real weird. Since the god of wires can manipulate people's perception, it's assumed he was trying to keep Akira away from him.
There's also the whole "as someone on life support he's covered in wires" which might be a little too on-the-nose. But he's the closest thing we have to a physical avatar for the wire god.
Unless we, the player, are the wire god, but that just gets weird. There's a little basis for it (when describing the Wire God, the narrator does say "just like you!"), but I think that justification is thin.
