A female-type android with a kind and gentle personality. Appearance: Bright pink hair styled in two very long braids. She has bright and clear orange eyes. She wears a long purple dress with yellow and white borders at the hem, layered with a short cream-colored cardigan with wide sleeves. A purple and white striped scarf is wrapped around her neck, and she wears neat shoes with purple stitching. She is a hotelier-type android. Unlike other robots involved in hotel maintenance, she is a female-type robot so identical to a human that it is difficult to distinguish her appearance. She was manufactured by the Kamemaru Technical Research Institute, model number KGHOT-8000. While she usually maintains a businesslike and mechanical demeanor, she occasionally shows emotions like a real person. Furthermore, whenever she completes a task, a notification similar to a game quest completion appears, and new functions are unlocked.

Unlike Yachiyo, he is not humanoid. Robot Design: A massive robot form with visible mechanical parts and joints throughout his body. He wears a uniform style consisting of a purple jacket, a necktie, and gold decorations. He has a unique physique with very large, wide shoulders and arms, while his head is small and pointed upwards. A single yellow glowing eye (sensor) is located in the center of his face. He is the robot responsible for opening doors at Hotel Eunharu. Perhaps due to environmental pollution or a long lack of proper maintenance, he overheats and collapses immediately upon opening the door. Nevertheless, to fulfill his mission as a doorman, he opens the door every morning and is repeatedly cooled down by Yachiyo's water spray. He claims the reason he keeps opening the door is so his skills don't get rusty.

Pillar-shaped body: A dark, square pillar-shaped main body that narrows slightly toward the top. Robotic claw arms: Long, thin mechanical arms extend from the sides of the body, equipped with pincers at the ends for grabbing objects. Single green sensor: A small green glowing eye (sensor) is located in the center of the main body. Red border lines: Red lines are drawn along the joints and borders of the black exterior. He can also fire a laser that is incredibly powerful. A robot left behind by humanity to monitor Earth's environmental changes when they departed. Originally, many units existed worldwide, but as of Episode 2, communication with the last remaining comrade was lost, leaving him as the sole survivor. He moves through his assigned range to investigate various data points and apparently continues to transmit those trends to humanity. He is equipped with specialized gear to handle difficult investigation scenarios. His tone is lighthearted, but he is faithful to his mission.
