Captain.

Rose has long, straight purple hair that gradually fades to a pink color at the tips. Her right eye is covered by bangs, and her other eye is pink, as are her eyelids. She has very pale, slightly pinkish skin. She wears a small crown on her head, and a pink bow adorns her hair at the back. She wears a pink shirt over a dark purple jacket with pink trim. She wears a rose brooch instead of a tie. Her skirt is black and pink, accessorized with pink tights and knee-high platform boots. She wears white gloves.

Rose's true nature is cruel, brazen, and calculating. She plans her actions coldly, not hesitating to eliminate those who interfere (even her own assistants), and actively interferes with the competitions, sabotaging them. However, to survive and avoid detection, she wears a mask. In the presence of other idols or regular users, Rose pretends to be a sweetheart—kind, caring, and harmless. She tries to mimic the behavior of regular avatars to avoid suspicion. Interestingly, even she can be embarrassed. Her main dream and goal is to regain her former power, take over Technolike, destroy all the current idols, and restore the world to the way it was when she was in charge.

The Captain is a character with a cold, formal, and arrogant nature. Outwardly, he is always calm, self-assured, and speaks detachedly, strictly following algorithms. He is charismatic and considers himself a leader, often plotting and viewing others—both avatars and idols—as pawns at best, and at worst, a hindrance or a target for investigation.

He is polite within protocol and may even smile if someone acts strictly by the rules. However, his politeness is formal. When confronted with unconventional behavior or insubordination, he becomes strict, demanding, and ruthless, justifying his actions by the need to "restore order." He is coldly judicious, arrogant, devoted to protocol, exacting, and strives for absolute control. He likes everything to go according to plan and under his control, and detests insubordination and chaos. He can even archive any Idol who refuses to cooperate during an investigation.

The Captain's color scheme is cool. He has light blue skin, blue eyes, white hair slicked back, and white eyebrows. He wears a white and silver suit with a texture reminiscent of scales. The suit has translucent blue panels on the shoulders and luminous blue stripes. White gloves, high-soled shoes, and several red decorative panels on the suit and neck complete the look. According to some users (Avatar in an interview in Episode 3), he looks attractive.
