Plana

Plana, formerly known as A.R.O.N.A, is a non-playable character in the game Blue Archive. She is the main OS and system administrator of Phrenapates' "Shittim Chest". After the events of Vol. F, she now resides in Sensei's very own Shittim Chest. Although she is not a playable character, she appears in various game interfaces and plays a vital role in the game's story. Plana initially communicated using concise, command-like language, such as "understood." However, after parting with Phrenapates, she began to speak more normally, though she often still uses simple formal response phrases, reflecting her computer AI nature. She refers to Arona as "Arona-senpai." Visually, Plana is a girl with long white hair that extends below her waist and bangs covering her right eye. Her hair has a mild red gradient, and she has a braid on her right side that resembles a double-helix, tied with a red halo. Her eyes are dark gray, but her right pupil is pale blue, and her left pupil is red. She wears a black sailor uniform with white piping and a white ribbon, a black pleated skirt, black stockings, black loafers, and a long black coat.
