In Free Play mode, items can be selected on the Song Start Screen by selecting リズムゲームアイテム (Rhythm Game Item). Doing so will open a list of the Items and will be used in the following song. Only up to three items of the same type can be used at a time. Unlike the previous DIVA games, all of these are free, but Free Play mode won't affect any progress for Live Quest mode.

The Rhythm Game Items are divided into Help and Challenge Items. Help Items will make the song easier but also will give you less DIVA Points at the end, while the Challenge Items increase difficulty. If an item is used the category will be shown in the upper right of the HUD, during the song, and the result screen. A small green heart will be displayed next to the rank on the Song Record when a song was cleared with a Help Item. There is no indication for Challenge Items.
