Metatag

Metatags (or Encoded Tags)are spelltag-like pieces of cybersubstance, in Daikoku, these are mostly made by Megabaa and Tamako. Metatags are made out of Metabugs that are fused together and rolled in a machine. When applied to a piece of cybermatter such as a surface or cyberbody, they execute a prepared encode. All metatags are single use and disappear after they finish their function.

Coil Tag
The Coil Tag is the rarest of Metatags, as the primary Metabug for it no longer exists. Only Megabaa, Tamako and Haraken are known to have them, but only Megabaa has ever made them. She had one in her Megashi store, but it was used to return Kyoko's cyberbody to her real body.

Wall Tags
Wall Tags, such as the Steel Wall and Brick Wall tags, are one of the most common tags, often used by Fumie to protect herself from Kyuus and Satchi. They do not directly affect the real world, and can be destroyed by Megane-beams, certain Illegals and cyberweaponry, though the Steel Wall is shown to be much more durable than the Brick Wall.

Megane-Beam
The Megane-Beam allows the user to shoot a blue beam from their forehead, much like the beams Satchi and the Kyuus use to remove Obsolete Spaces. There has only been one type of Megane-Beam seen so far, used by Fumie and Yasako. It has a ten-second use before it needs to charge.

Barrier Tags
Barrier Tags have not been seen much, but it is known that Megabaa has a large amount set up around her room and her Megashi store. They stop Illegals from entering, though it is seen that they can be broken by the presence of enough Illegals.

Resistance Tags
Fumie uses one of these to give extra protection to her servant, allowing it to survive inside an Obsolete Space. It is unknown how effective it is, though Oyaji shows no glitches or bugs after entering the Space.

Traffic Tags
This tag changes any green light to a red light, making it one of the few cybersubstances seen to affect the real world. It also changes red 'Don't Walk' signs into green 'Walk' signs, making it possible to cross the street faster.

Download Accelerator Tags
Fumie uses one of these tags on Densuke when the automated system restore in his doghouse fails, after applying the tag, the system restoration successfully connects to the Coil domain and begins a download.

Vaccine Tags
This tag executes a vaccine program to remove computer viruses. One is created by Megabaa to help Densuke recover after it becomes infected by an ilegal from obsolete space.

Old-School Tags
These tags were found in yasako's grandfather's room; they are effective at stopping Searchmaton 2.0 units for a short period of time. Because these tags are based on older Coil technology, adding them to an Encode Reactor can damage a linked Imago system.
