"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". 

A supporting character of the game, I was imagining a gentle and informal voice for this character, since this is a fandub, feel free to any little quips you feel fit! Will have a few lines in the beginning of the dub.
