Salu (サルー) is a member of the Crimson Knights and is one of the players under the authority of Silver Knight. He served loyally as a Knight until the Guild was dissolved by Subaru. Following the disbanding of the Guild he approached Subaru, asking what he was supposed to do without his job as a Knight. Subaru told him that he should find and serve his own sense of Justice, rather than following one created by another. What became of him afterwards is unknown.
