Aru Terror

Plana, formerly known as A.R.O.N.A, is a non-playable character in Blue Archive that resides in the Shittim Chest alongside Arona.

The main OS of the Shittim Chest and Arona from another timeline. She is the manifestation of the damaged Shittim Chest from alternate timeline shot by Shiroko Terror, before reactivating when Phrenapates appeared.

Unlike Arona, despite also being the AI of the Shittim Chest, Plana generally spoke with simple commands, such as "understood." However, after parting with Phrenapates, she begins speaking more normally, though she often still speaks like a stereotypical computer AI by using simple formal response phrases. She calls Arona "Arona-senpai".

Plana is a small girl with long white hair that extends below her waist and bangs cover her right eye. Her hair has a mild red gradient as it goes down, and she has a braid on her right side that looks like a double-helix with a red halo around where it's tied. She has dark gray irises, but her right pupil is very pale blue, while her left pupil is red.

Plana wears a black sailor uniform with white piping on the edges of the collar that's tied with a white ribbon, a black pleated skirt that reaches just above her knees, black stockings, black loafers, and a long black coat

Her halo is a simple red ring. Much like Arona, her halo changes depending on her mood.

She appears to be carrying a long-ranged rifle, likely to be a two-toned black and white Pattern 1914 Enfield bolt action battle rifle, wrapped in black shroud, similarly to Shimoe Koharu's, though she is holding it by her two hands,

Arona resides in the mysterious Shittim Chest. She accompanies Sensei throughout their adventure in Kivotos as a guide.

She is the main mascot of Blue Archive, appearing as the figurehead on its website and social media. In addition to providing information and updates to Sensei, she also runs a series of videos called Arona Channel.

Arona is a self-proclaimed high-performance AI who serves as the OS of the Shittim Chest. She resides in a desolate classroom located in the midst of a watery expanse, stretching further than the eye can see. When she's not helping Sensei with their tasks, she's up to goofy antics that appear on Arona Channel.

She has a child-like personality and is quite gullible, often falling for Sensei's jokes. Arona thoroughly enjoys sweets, being quick to abandon a diet for the sake of sweets—or even breaking into tears from being denied them.

Arona is a small AI girl with short sky blue/violet hair with bangs covering her left eye, a white headband with a large bow, and braids tied to her left side. She has bright blue eyes and has heterochromia, with the right eye having a blue pupil and the left having a violet pupil. Arona's halo is interchangeable based on her emotions. She resembles the president of the general student council.

Her normal halo is a simple blue ring that resembles a stock power button LED ring sometimes found on certain desktop computers, but it changes to different colors and shapes based on her mood: Default: Blue Circle Happy: Pink Hearts Shocked: Light Blue Spikes Sad: Dark Blue Drip Motivated: Green Stars Angered: Orange spikes

The sailor uniform is tied in a ribbon with long sleeves; has a white collar, and white ribbon ties with an LED ring stuck in one of them. The choker and white sneakers have bow-like shoelaces. Her white skirt has △✕＋〇 symbol on it.

Can protect Sensei from bullets, explosions and any harm but not too much.

She has long, straight shoulder-length pink hair with bangs that cast shadows over her eyes. This lends itself to her trait: the appearance of a villainess or a demon queen. This is augmented by her haughty and pretentious smile and the horns that grow out of the rear of her head. Said horns are wine red, with symmetrical golden accents.

Aru wears a red Captain's coat with golden buckles, a long-sleeved collared white shirt, white gloves, a red ribbon around her neck, and an office skirt with gold-strapped high heels.

Aru's halo has a smaller circle slightly slanted to her left. A larger disfigured circle with dashed edges and stripes on both side surrounds the first circle. The second circle resembles a crescent moon. When looking at the inner and outer circle together, her halo somewhat resembles an eye.

To the left and right sides of her halo, horizontal lines jut out sharply like spikes. Because of her halo, she doesn't get affected easily by physical damage so if her halo fades she is either asleep, unconscious or dead.

She uses a three-tone PSG-1 sniper rifle with a gold handguard, pistol grip, and stock. It has a black cheek rest and barrel. The rest of the receiver and most of the Hensoldt ZF riflescope is painted in maroon. Some short maroon belts wrap parts of the handguard. A gold rose decal can be seen on both sides of the receiver. The Handyman 68 insignia is stamped on right side of the cheek rest.

Rikuhachima Aru is one of the students studying in Gehenna Academy who wields a Sniper Rifle.

She is the self-proclaimed leader of the Club Problem Solver 68.

Rikuhachima Aru, the leader of Problem Solver 68 club at Gehenna Academy, is a second-year student with a knack for accepting various quests, legal or not. She puts on a cool, beauteous, and villainous facade but often breaks character, revealing her true caring and meticulous nature when teased or pressured. Behind her mischievous personality, Aru is a shy artist, striving for perfection. She has a thirst for knowledge and constantly seeks to expand her understanding of the criminal underworld, enhancing her problem-solving abilities. While not exceptionally intelligent, her unwavering determination and focus on her goals make up for it.

Aru persists relentlessly until her tasks are thoroughly accomplished, though she can also be goofy and prone to panicking when things don't go according to plan. Her true goal is to make Problem Solver 68 a reputable criminal organization. She constantly tries to impress Sensei on many occasions, and frequently asks them to become a member of Problem Solver 68, despite their constant refusals. She indulges to her obsessions of portraying a delinquent and idolizes the image of a criminal without comprehending the true nature of such individuals.

The self-proclaimed “Boss” (i.e. president) of Club Problem Solver 68, Aru is a 2nd year student at Gehenna Academy. She conducts her illegal business however she pleases. While Aru always puts on a cool, beauteous, and villainous facade, she has a habit of breaking character often and exposing her true personality when teased or pressured. Despite the vain and conceited persona she wears, Aru is meticulous and caring for the people she is close to. There is definitely more to her than she lets on.
