Saviors who are able to use Light Arts has prana, the power source required to use Light Arts. Differing from the Kuroma who uses mana to cast spells, Shirogane is able to use their prana to enhance their physical abilities to superhuman levels. However, before a Shirogane can use Light Arts, all of them are first required to unlock their "Seven Prana Gates", which are located on the seven places on their bodies: Left Hand, Right Hand, Left Leg, Right Leg, Solar Plexus, Heart, and Brow.
After unlocking all these seven gates, one will be able to cover their body in prana instead of just some parts of their bodies. Differing from Kuroma, Shirogane can use their prana to heal their injuries.

Edward has described that it compresses space.

It is rare for Shirogane to unlock all seven of their prana gates on their first try after entering school until the arrival of Moroha Haimura, but Gen Isurugi doesn't count since he trained for it with his brother before his arrival to Akane Academy.
