Unlimited Desire (アンリミテッドデザイア Anrimiteddo Dezaia) or Infinite Desire (無限の欲望 Mugen no Yokubou) was a top-secret project conducted by the TSAB High Council in order to obtain Lost Logia-class weapons for the TSAB. The result of the project was Dr. Jail Scaglietti, an Artificial Mage and a brilliant scientist implanted with a grand dream (the eponymous "infinite desire") to obtain the long-lost secrets of the Ancient Belka and Al-Hazard. The JS Incident was a direct consequence of the project.
