Area items are found in various SEKAIs, Kamiyama High School, and Miyamasuzaka Girls Academy. These area items increase the power of your cards, based on the characters, attribute, units, and support units (if applicable). Having a party with cards of only one attribute will double the power bonus of the associated area items. Similarly, having a party with cards of only one unit will also double the power bonus.
Each SEKAI contains a character item for each character in the unit, a character item for each VIRTUAL SINGER in that unit, 2 unit area items for that unit, and 1 unit area item for VIRTUAL SINGERs. For example, in the Classroom Sekai, there would be character area items for Ichika, Saki, Honami, Shiho, Miku, and Luka, 2 unit area items for Leo/need, and 1 unit area item for VIRTUAL SINGER. Ichika, Saki, Honami, and Shiho are members of Leo/need, and Miku and Luka were starting VIRTUAL SINGERs in Leo/need, for a total of 6 character area items in the Classroom Sekai.
The two schools, Kamiyama High School and Miyamasuzaka Girls Academy both contain attribute area items for each attribute, for a total of 10 attribute area items.
