Olive is a student of Hachiko Highschool in grade 10. They are a non-binary, autistic mutt who could be described as silly and idealistic. They are nervous at first and have a stutter, but as you get to know them, they are friendly and sweet. They love bacon treats and hugging, and in contrast, they hate loud toilet flushes and violence. They also think all dogs can be good, which leads to them trying to fix Patches. Sometimes their naive and idealistic mindset gets them into bad situations.
