A small machine that, when swallowed, causes a person's brain to operate 12 times faster. Used in Layer 02 by a boy in Cyberia. Not considered a drug, but traded like one and priced rather exorbitantly; up to ten thousand yen, with the usual price around four thousand.
It is delivered in a paper parcel and held in an organic-looking capsule filled with fluid -- the boy splits the capsule open using a box-cutter and ingests the machine with a swig of beer.
It becomes much more difficult to obtain after the shooting in Layer 02.
