Appearance: A boy around 10 years old. A robot designed for medical and rescue operations. Speech Style: Soft and airy, intended to keep the rescuee calm. Primarily uses polite language (rarely speaks casually). Standard Appearance: Light blue hair, white skin, and red eyes featuring a plus-sign (+) mark in the pupils. Small and short (around 140cm) to facilitate easy escapes, though his strength is a different story. Upon locating a survivor: He is programmed to always say, "I am a Plus Boy. Are you injured?" with a smile. Prioritizes the protection and treatment of the target. If monsters are still present, he is capable of high-speed movement while carrying the survivor and can use blinding attacks against enemies. As a robot, he has infinite stamina.
