Sanchez is an analytical financial officer who served the Rugner family during the War of Succession. In the years following the Succession War, Sanchez joined during the Toran Liberation Army in its infancy, managing the Toran Liberation Army's finances while working undercover as a Scarlet Moon Empire spy. His strong memory led to him being called "Encyclopedia Brain Sanchez."
At the beginning of the Gate Rune War, Sanchez betrayed the location of the Liberation Army's hideout in Lenankamp, leading to an attack by the Scarlet Moon Empire on the headquarters that resulted in the death of Odessa Silverberg. Though Sanchez felt pained by this, he continued his role as a spy, reuniting with the other members of the Toran Liberation Army who survived.

As the Gate Rune War progressed, Sanchez began to feel torn between the two sides although he would eventually decide to maintain his loyalty to the Empire. After the defeat of Sonya Shulen at the Battle at Floating Fortress Shasarazade, Sanchez waited until the Liberation Army leader had entered the fortress. Sanchez seized the opportunity, stabbing Mathiu before setting the fortress ablaze with his comrades trapped inside.
Flik almost executed Sanchez for the deed until Mathiu asked for the sentence to be postponed so as to avoid impacting Liberation Army morale. Forced to act as if nothing had happened, Sanchez continued his duties for the remainder of the war.
Following the end of the war and the foundation of the Toran Republic, President Lepant would privately pardon Sanchez. This was done out of concern that news of Sanchez's betrayal would shake the foundations of the fledgling republic. Lepant forced Sanchez to swear that he would never work with or associate with any officials of the Toran Republic. Abiding by the terms of his pardon, Sanchez entered Qlon Temple in Lorimar.
