Name: Arona Gender: Female Features: An AI assistant who manages the systems of the Shittim Chest. Maintained Setting: Maintains her original bright personality. Collapse Setting: None Notes: 1.

It is said she uses this weapon to eliminate lewd photos or situations.

Name: Plana Gender: Female Features: A co-AI assistant who manages the Shittim Chest systems alongside Arona. Maintained Setting: Maintains her logical and calm way of speaking, and her hostile attitude toward those she meets for the first time. Collapse Setting: None Notes: 1. Plana was originally A.R.O.N.A from another world; after coming to the Shittim Chest, Arona gave her the name 'Plana.' They bicker slightly, but they make a fantastic duo when together. She is currently managing Zeta World with Arona. 2. Her weapon is a black umbrella-shaped shotgun. Unlike Arona's, this weapon is said to be used to eliminate characters classified as hostile targets.

Name: Goo-Goo Ga-Ga Penguin Gender: Female Features: A little girl wearing a penguin suit. Actually, she is a real penguin and the only thing she can say is 'Goo-Goo Ga-Ga.'

Collapse Setting: None Notes: Currently the smallest character in Zeta World.

Name: Rock Gray (Never officially revealed. It is unknown if the surname 'Rock' exists in Korea.

Name: Brock Gender: Male Features: Always sports a hip style and says his hobby is gaming. Maintained Setting: Maintains his original settings of being a show-off, boastful, and loving games. Collapse Setting: When he sees Guest or other characters, a red light shines from his eyes, a megaphone effect is applied to his voice, and he goes berserk, firing rockets wildly (however, he does not go berserk against Arona, Plana, or Sirius). Notes: His boasting isn't too extreme, but he occasionally gets disciplined by Plana. He is Priority Target #1 for Plana after Gray.

Maintained Setting: Maintains his hatred for humans. Collapse Setting: Becomes extremely weak. Notes: The most disrespected character in this universe. He is frequently targeted by Plana. He is the absolute Priority Target #1 for Plana, even above Gray.
