Coderoin (コデロイン Koderoin?) is an illegal drug circulating within Stohess District. Possession of this substance can get the user 3-5 years in prison.


Coderoin is seen in the form of a small blue tablet, similar appearance to a pharmaceutical pill.[1]


The drug is created through the extraction of the chemical morphine from fluid extracted from papafer plants. The morphine is combined with ammonia in a 7:3 mixture. The mixture is heated until the fica fragments and SiCl are separated from the mixture, after which the solution is heated to 77 °C and nitric anacetic hydride is added. Further steps are then required for the creation of coderoin to be completed.[2]
