The individual parts of the suit overlap on multiple places, to ensure the wearer is completely covered and protected. Each part locks itself in place when donned, the unlocking mechanism only accessible from the inside. Putting it on is a one-time, permanent action: Partly or completely cutting off the supply of oxygen to the skin, depending on the size of the wearer, being inside the Centurial Steel is detrimental to the health of even the strongest warriors. Only the toughest, most disciplined warriors would survive in the suit as long as its name suggests.
