Hoho-sensei teaches the young animals of Crescent Moon Forest and also acts as the forest's doctor. A brown-horned owl, his outwardly gruff demeanor conceals a deep kindness and dedication to his students' health. He regularly invites them to his home, though students dread these visits because he insists they drink his intensely bitter health tea – a brew universally disliked but showcasing his commitment to their welfare.

During these gatherings, he often shares long stories from his own youth, aiming to teach wisdom or morals. His father, Rouhohhoo, appears in these tales, though the specifics of their relationship remain undefined. While known throughout the forest for sternness, Hoho-sensei also possesses a recognized, if often hidden, benevolence. This emerges clearly when students make mistakes or face emotional distress.

A notable incident involved the student Clover, who falsely accused fellow residents of theft. After a nightmare where she saw herself banished and rejected following her guilt, Clover confessed her lie to Hoho-sensei and her mother. His role focused on receiving her confession and helping clear the names of the wrongly accused, implicitly aiding in resolving the moral failing. This event highlights his position as an authority key to upholding the forest's social order and ethical standards. His interactions consistently demand responsibility and learning from errors, framed by his stern yet caring approach.
