Plana, formerly known as ARONA, is a non-playable character in Blue Archive who resides in the Shittim Chest with Arona. She is the main OS of the Shittim Chest and Arona from another timeline - the embodiment of a damaged Shittim Chest from an alternate timeline that was shot by the Shiroko Terror, before being reactivated when Phrenapates appeared. Unlike Arona, despite also being the AI of the Shittim Chest, Plana usually speaks in simple commands, such as "understood." However, after parting ways with Phrenapates, she began to speak more normally, though she often still speaks like a stereotypical computer AI by using simple formal response phrases. She calls Arona "Arona-senpai".
