Technology of Interest

Technology of Interest, or TOi, is an application in XBlaze – Code: Embryo that can be used to alter the course and outcome of the story depending on what articles are read or left unread. It appears again in the BlazBlue: Bloodedge Experience novels.

Information
TOi is an incredibly popular application that is enjoyed by people of all ages across the Earth. It analyzes the preferences, enjoyments, and interests of users and gathers information from the Internet; it will gather information for users, even when not in use. Its creator is a mysterious person only known to the public as TC.

Like other modern-day applications, TOi's reception net may not reach certain areas, such as New Kawahama First High School.

During the events of XBlaze – Code: Embryo, a bug appeared in the TOi system, which caused articles unrelated to users' defined interests to be displayed, which is why Tōya Kagari started to get articles that other people are interested in.

In-game use
In-game, TOi will be displayed when it's accessible. There are three different types of icons that the TOi will display. The TOi icon indicates that it will be accessible, lest only for a short time; it will flash when a new article has been added. The locked TOi icon indicates that it cannot be accessed during the time; this only happens when the protagonist is not present or has no time to read articles. Finally, the TOi Event icon indicates that a TOi related event is happening, making the app unavailable.

Instances known as TOi Events mostly occur when the player reads articles that were also read by someone other than the protagonist. These articles trigger scenarios related to them, and change the outcome of the story. In the gag scenario, event articles do not trigger any scenarios, and the message they display only indicates that this is the right article that will progress the story further.
