==Terminology==

===What is the Cyber Troopers Virtual-On as a Next Generation Game?===
A fighting game played using giant Virtuaroids that appear in the actual city streets. Whether a Level 5 or Level 0, anyone can fight equally as long as they have the proper technique, so it has explosively spread throughout the students of Academy City. Even when fighting in the streets, stray shots will not blow away buildings and the giant weapons will not crush passersby. The latest portable devices that have recently taken Academy City by storm are used to represent the battles. There are two ways to defeat an opponent in Next Generation Game Virtual-On. The first is to score more points than your opponent by the end of the game. The second is to destroy every member of the opposing team. Preliminary matches are being held in each of Academy City’s districts and then a tournament will be held between representatives of all 23 districts. Victory there will make one the strongest player in both name and reality.

===Game Rules===
The game ends when one side wins two of three sets. But unlike a normal fighting game, the primary goal is not to wear down a gauge representing stamina or armor. More like judo or wrestling, the points earned from “legal blows” determine the winner (i.e. it is a form of e-sports). Virtual-On is generally won by scoring more points in two of the three sets, but KOs are also possible. And if every Virtuaroid on a team is destroyed, that team is defeated and the game ends.

===Portable Device===
A handheld device used to play Virtual-On. In addition to the game, the device also supports one’s everyday life. Kamijou originally played Virtual-On to refill his electronic credits on the portable device.

===V-Converter===
Virtuaroids do not actually exist there; they fight as materialized data. The V-Converter acts as the core of that system. The V-Disc inside is something like the blueprints for the Virtuaroid, so the V-Disc is read to materialize the Virtuaroid.

===V-Crystal===
A substance that accumulated in great quantities at the lunar ruins known as the Moon Gate in another world. Crushing it and applying it evenly to a giant disc creates a V-Disc, so it is the core ingredient of the V-Converter.

===Cradle Station===
Next Generation Game Virtual-On is generally played on a portable device, but a lot of users play by enclosing themselves in egg-shaped cradle stations installed at the centers located around Academy City. They provide a higher resolution image and slightly less latency (although the portable device is still used as the controller even inside the cradle). The difference is similar to enjoying the same video on a handheld player versus a home theater system.

===Lilina===
The Support AI that automatically activates when a user privately registers their portable device. A single AI is stored on each device. They primarily share information about Virtual-On and provide support during battle. They seem to have a high-level learning function, so their personality is different for every user.

===Material Analyze===
A service that allows a target material’s traits and properties to be incorporated into a Virtuaroid just by holding the device in front of an object. This works with both mechanical and biological objects, so the structures of existing weapons or of insects and other animals can be incorporated. This extremely high level of customization is one aspect of Virtual-On.

===Blue Stalker===
A blue Cypher Virtuaroid. Uses a coloring not found in the defaults and its user name is corrupted. An outlaw player that intrudes on proper battles and destroys everything. Given its nickname, it seems to be pursuing someone…

===Reverse Convert===
A rumored feature(?) of Virtual-On in Academy City. As a Next Generation Game, Virtual-On allows users to adjust their Virtuaroid’s parameters using the Material Analyze feature, but the Reverse Convert can supposedly go the other way and transfer the customized Virtuaroid’s data to the player. However, there are many mysteries concerning how the Material Analyze applies altered effects to the Virtuaroid and some rumors claim these effects can reach the actual human body piloting the Virtuaroid…

===The Phoenix===
An underground online search engine in Academy City. It allows one to search for information not normally available, but this search engine is a crucible of malice and it will destroy the personality of any normal person who stays there for too long.

===The Tangram===
According to information from another dimension, it is a Space-Time Continuum Control Mechanism that can be called “the entity at the center of all things” and that is “a single entity that also simultaneously has alibis in every single parallel world”. Successfully contacting it provides control of time, causality, destiny, and all else that is similarly beyond reach, so it places the world in the palm of your hand.

===L’Ln Plajiner===
The girl who develops and manages all cutting-edge technology. Also the creator of the Tangram

===Code Phoenix===
Unknown.
