Each district has fashion trends that affect gameplay. By wearing pins or clothing from the more popular brands in that district, items' effects will be improved; wearing the least fashionable items will do the opposite, and items from brands in between are not affected. However, the player can increase a brand's popularity in one district by repeatedly fighting battles in that district while wearing items of that brand. The player can enter shops to buy new pins, clothes, and food items that are gradually consumed during battles to improve the characters' basic attributes.
