The protagonist of Child of Alchemy. He's developed by the labs of Alchemists Inc. as a brand new experiment among the Philosophers. He's a blank slate, a silent protagonist for the player to control. He's dressed in casual wear with white neon lights running from his shoulders down to his stomach. On his chest plate is a circle with a horizontal line dividing it symmetrically, the alchemic symbol for salt.
As an experiment in the field of Philosophers, Sal has the ability to cop abilities of other Philosophers he makes contact with. Unfortunately, his storage capacity has to be upgraded before he can copy certain Philosophers.
