Pact

From The World Ends With You

A pact is the partnership between two Players during the Game. Neku has 3 possible partners: Shiki, Joshua or Beat (depending on the chapter). Symbolized by the Puck in battles, the pact is not simply an agreement; it is a binding force between two Players, and its benefits are vital to their survival in the Game. These benefits include the ability to activate psychs and the prevention of unwanted battles with Noise (except those set upon them by Reapers and Taboo Noise). A Player whose partner is erased has seven minutes to make a new pact before being erased him- or herself. As any nearby Player will probably already have a partner, erasure is almost certain.

A pact is required to activate any psych abilities and protect the Players from unwanted Noise. Without a pact, Neku cannot deal any damage and his only option is to escape from battle.
