Union

Drive-Infected Patient (ドライブ) is a human afflicted with a Crystal on his body. They are collectively known as the Drive-Union and are under the protection of the Mitsurugi Agency. Drive-Infected Patient only appears in XBlaze – Code: Embryo.

Information
Crystal is 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-Infected Patient.

The Crystal in a Drive-Infected Patient's body converts Seithr into a unique ability that the Union can use, however, this ability comes at a price: the spirit of the Union becomes polluted and leads to extreme erratic behavior.

For unknown reasons, the Mitsurugi Agency protects, manages and treats the Union. Kazuto Kotetsu is somehow involved with the Union.

Trivia

 * Ripper is the only Drive-Infected Patient whose spirit hasn't been polluted.
 * Drive-Infected Patient shares similarities to Ars Magus users as they draw out Seithr from the air to use for special abilities.
