The Twilight Bracelet (黄昏の腕輪, Tasogare no Udewa) is an item that gives the user the ability to Data Drain and Gate Hack. Its power may prevent the user's data from being altered, though this might also be simply a secondary effect of the install book used to acquire it.


Bestowed through the installation of “The Book of Twilight” that Aura had given to him, Kite used the Bracelet in his quest to save his friend Orca. During the time, the Bracelet was the main means of offense against Morganna and the Eight Phases of the Cursed Wave. In order to stabilize The World, Kite preformed Data Drain against seven of eight, however the Bracelet fell prior to the final confrontation. Upon the defeat of each Phase, the power within the Bracelet grew, however at the same time its shadow, Cubia, also grew in strength. Kite fought against this shadow numerous times, each resulting in its retreat, yet with Aura’s completion Cubia stopped running. Both The Bracelet and Cubia were two sides of the same coin, thus in order to defeat Cubia once and for all, Kite had Blackrose destroy his Bracelet, causing Cubia to vanish along with it. In the game Mia is the only person who can see the bracelet normally. In .hack//Another Birth only Kite's party are able to see it otherwise.

Installed via the installation book “Twilight ~ Daybreak” Kite once again receives the Bracelet from Aura. This Bracelet is presumably without shadow, unlike the previous one. Like the Bracelet prior to its creation, it grants the user the ability to perform Data Drain. (The same Bracelet is seen during the credits of Quarantine being placed into an installation book, though whether it is the original reconstructed is unknown.) Another bracelet would return years later.

Once installed, a new tab in the user status screen appears called "Data Drain." When open, the available Data Drain skills and virus infection level are displayed. As the user continues to use Data Drain and Gate Hacking, the user's infection level rises. The infection level is also referred to as the virus spread rate, and it is displayed via a color gauge as follows:

- 0-25% spread rate: Blue
- 26-50% spread rate: Green
- 51-75% spread rate: Yellow
- 76-99% spread rate: Orange
- 100% spread rate: Red

The higher the spread rate, the more often side effects occur.
