Summary
Cross-Dimensional Observation System No. XX, also known as System XX or System, is the main antagonist of BlazBlue: Cross Tag Battle. Having been originally created by Clavis Alucard, she was designed to be capable of creating new possibilities, and in order to achieve Cross-Dimensional Observation. However, due to flaws in her design, she went rogue and began acting on her own, attempting to invade the world she Observes. This forced Clavis to her away using the Keystones of the BlazBlue, RWBY, Persona 4: Arena, and Under Night In-Birth universes. Despite his success, the seal was accidentally broken by Rachel Alucard, Clavis' daughter, later on, thus re-activating System XX and allowing the latter to summon warriors from the aforementioned selected universes, tricking them into participating in the "Keystones Tag Battle Tournament" taking place within the Phantom Field.
