The Nitro Rice (ニトロ米, Nitoro Mai) is presumably a cereal found in the Dark Continent, in the swamps south of Lake Mobius. It is said to be able to extend one's life. In the past, the Federation of Ochima attempted to retrieve it, but 99% of the members of the expedition fell prey to the Hellbells that inhabited those swamps, with only 11 of them surviving.
