The Organic Material Cycle System (OMCS), also known as "omshis," is the food processing system used aboard the battleship Yamato. OMCS units placed along a wall of the ship's mess hall take in all available organic substances--including waste products--and converts them into safe, recognizable dishes. OMCS can create a wide variety of offerings, including rolls, cake, curry, fried rice, kabayaki, soup, protein bars, and parfaits ("Gravestone on a Frozen Field", "The Planet That We Head For"). Alcoholic beverages are also available ("Toward a Sea of Stars").
