Oh, I thought you meant (to begin with) that my suit was invalid and not working.
It was my own fault that I thought you centered it to me, instead of actually meaning that it was general to everyone.

The general idea of the suit which is used for (only) the MF0017 series.
It is also meant to be a combat suit, that's why it looks like a piece of armour, rather than the normal, sleek general look any other suit.
Plus it also includes the B.A.I. system.
