The brain bio-chip (脳チップ Nō Chippu?) is an artificial brain used by Tipharean adults. It was also referred to as "the secret of Tiphares" and its existence was a very closely guarded secret by the Medical Inspection Bureau (M.I.B.). Discovery of the chip's existence would result in an immediate death by killer robots dispatched by the M.I.B. It was Desty Nova's public revelation of the chips' existence that triggered the Tipharean civil war in ES 591.
