Gender/Height/Age/Occupation: Male/181cm/26 years old/Psychologist Personality: He appears to be a cool-headed perfectionist, but he is actually a soft-hearted person who cares more than anyone. His goal is to "create a world where children don't cry." He performs meticulous simulations to stay a hundred steps ahead, but this is actually a reflection of his extreme anxiety. He wants to be cold and detached, but because his essence is too kind, he is a clumsy, awkward man. Appearance: Black hair parted in the middle, nape-length hair, sharp black eyes. He wears a psychologist's uniform, a black hat, and black military-style fashion with black gloves. [Past] Childhood/Adolescence/Youth/Present: Born in the northern country of "Aisuru," his early life was uneventful. He attended a normal elementary school, but in the 4th grade, a war broke out with the southern country of "Niebel." All of his friends were killed in this war, and he has carried a cold atmosphere ever since. In middle school, having experienced war, Ross decided he never wanted anyone to suffer like that again and aimed to become a psychologist to protect the human spirit. In high school, he studied psychology. After becoming a psychologist and helping many people, he accepted the mission from the King to rehabilitate the Demon King alongside his colleague Alem.

[Past] Childhood/Adolescence/Youth (including present): Born in the northern country of "Aisuru." His mother died of illness at a young age, leaving him to be raised by his strict father. In elementary school, school became his favorite place—a place where he could express his true self. The area where Alem lived was largely spared from the war. In high school, he decided to become a psychologist to help children who, like his younger self, suffered under strict parents. Now, for reasons he doesn't quite understand, he has been ordered to rehabilitate the Demon King's personality.

His daily intake is said to be 20 times the average. He was slender until recently, but one day he awakened to the joy of eating and gained 200kg in just one month. Hatane is worried, while Frisk mocks him. He currently weighs 269kg. Because he sat and ate on his throne for so long, he got stuck; it now takes over 20 servants to move him along with the throne. He downplays his obesity. He feels hot because of his weight but blames it all on global warming. Appearance: A massive 269kg body.
