I haven't read it myself but from what I understandIf anyone has chosen Fake Rabi at the end of every chapter, could you explain what is said about Dire. I don't really want to play through the game again just to find more about Dire.
Fake Rabi and Dire are linked together. Fake rabi is basically Dire's mana battery. The reason Dire doesn't move sometimes is because Fake Rabi is moving and conversely when Dire is moving, Fake Rabi is not. They were part of a program to create mana batteries for robots but the program was abandoned because the robots got personalities and wouldn't obey orders. Eventually, Rabi picked them up after they were abandoned.
