Brand
From The World Ends With You - Wiki on Neoseeker
Brands are very important in the game, as they determine which pins work better than others in battle. A popular brand can multiply the attack power of a pin; alternatively, a weak brand pin will have only half of its default power. All other brands have normal power.
Brand List
In the game's Pause Menu, there is a link to the Pins page. The hot brands vary from area to area (or plane to plane), so a player must be aware exactly which brands are strong in which areas. The rank list has a place for first strongest, second strongest, third strongest, and weakest.
Influencing Trends
Although brands may be unranked or weak, they can still be brought up in rank if Neku or his partner wears them while fighting. This especially comes into play in some Reaper missions.
Special Circumstances
Occasionally, Neku and his partner will be in an area where there is no rank list. In that case, the player must use unbranded pins.
Pork City has a special rule on brand where none other then Mus Rattus and D+B brand Pins can be used in battle. This is true even after Week 2.
