First I would like to clarify that the Longinus in normal mode is the sword and that the armor will be the Balance Breaker of it and will add in addition to the sword.
Each Longinus will have a rest mode where we will reveal a possible how the different parts of the Longinus in Balance Breaker mode would look like.
Everyone can use the Longinus but only those who will be judged worthy by these will be able to use it to its full potential and have the Balance breaker.
