Kibi is a gray anteater with a robust body and short stature. He has a long snout with a small mouth at the end of it. His eyes are small and dark, and his ears are round.
He is typically seen wearing his school uniform, which consists of a white dress shirt, an indigo vest, a dark gray tie, black suspenders, gray pants with dark gray vertical stripes, and brown loafers.
Kibi is kind, calm and responsible. When he notices something that seems out of place, he points it out. He cares about his classmates and proceeds to check if they're okay when he thinks something has happened to them. He is friendly towards the people he interacts with and forgives them when he knows what they did was an accident.
