Union

Drive-Progressors are humans afflicted with a Crystal on their body. They are collectively known as the D-Progressors Union and are under the protection of the Mitsurugi Institute. Drive-Progressors only appear in XBlaze Code: Embryo.

Information
Crystal, a rare mechanism that mysteriously generates on a persons body for no apparent reason; the chance that a Crystal generates is only one in ten thousand and, should a person grow a Crystal, the person becomes a Drive-Progressor.

The Crystal in a Drive-Progressor's body converts the element Well into a unique ability that the Progressor can use, however, this ability comes at a price: the spirit of the Progressor becomes polluted and leads to extreme erratic behaviour.

For unknown reasons, the Mitsurugi Institute protects, manages and treats the Progressors. Avenge is somehow involved with the Union.

Trivia

 * Ripper is the only Drive-Progressor who hasn't had his spirit polluted.
 * Drive-Progressors share similarities to Ars Magus users as they draw out elements in the air (Well and Seithr respectively) to use for special abilities.
