The Control Names 管理名, kanrina?), or True Names 真の名, makoto no na?), as they are usually called, are special identifiers that all of the inhabitants of Sol Cluster are forced to have by Clustania. These names provide identificators that register every activity that each person does, and while Clustania can search them for examining any potentially illegal or dangerous actions a person has committed, the names have to be input complete and without errors. Otherwise, the search won't turn up any results.
