Officer - East serves as an instructor to the Player Tsviet in the Online Mode of Dirge of Cerberus -Final Fantasy VII-. He also stands watch at the ranking board in Deepground. East once faced Weiss the Immaculate in combat; he only managed to survive by running.
East is present when the Player Tsviet encounters Azul the Cerulean and Shelke the Transparent for the first time, and he reveals that only Tsviets with a status of "Triple S" are given colors to add to their names. East states that Shelke is "special" because the color assigned to her is not actually a color at all.
East tells the Player Tsviet that Deepground soldiers who upset the Restrictor are brutally punished; he makes his last appearance when the Player Tsviet goes off to challenge Weiss in order to move up on the Deepground ranking board.
