Detectibased system is one that is based in the detective genre. This means that the detective genre heavily affects, or has affected the system, headspace, roles, functions, or the headmates themselves. However, it didn't cause the system to form and is not an origin.

Detectibased systems usually need the answers for everything or are just really curious. For example, they usually take their self-discovery as a case that has a solution, and they will do anything to solve it, which tends to make them really knowledgeable in the terminology.
