Collimo is a bat-like mascot created by the Japanese company Sanrio. He first appeared in the 2023 web series Kuromi's Pretty Journey where he is discovered secretly living in the attic of the Kuromi Base. When he eats spicy food he breathes fire. While being shy in person, he is very knowledgable and speaks more confidently online. Due to his long and difficult to remember name, he was given the name Collimo by Kuromi.
