Brushbuddy

フデムシ

Brushbuddy is a character in Witch Hat Atelier and a member of the brushbuddy species. He originally lived in the Dadah Range until he encountered Coco while she was taking the Consent of the Crown test. Following the test, Coco and the small animal returned to the atelier together, where Brushbuddy began his new life.
Brushbuddy is one of three siblings born to a "typical brushbuddy father and a typical brushbuddy mother" somewhere in or near the Dadah Range in the north of the Zozah Peninsula. Shortly after his tail reached its full length, Coco found him and brought him to Qifrey's Atelier, which became his new home.
Brushbuddy appears to be an average-sized white brushbuddy. His tail is at full length, indicating that he has reached maturity. A unique feature of Brushbuddy is a patch of fur between his eyes that differs slightly from the fur on the rest of his body.
Brushbuddy does not have a very distinct personality, but he often provides comedic relief. Like any normal brushbuddy, the small creature is attracted to magic ink, which is one reason Brushbuddy likes to stay near the apprentices of Qifrey's Atelier. Throughout the chapters, Brushbuddy is frequently seen with Richeh, suggesting that a bond has formed between the two. Brushbuddy becomes somewhat annoyed when someone pets or hugs him too much.
Brushbuddy is attempting to write a journal based on the behavior of Coco and the others at the Atelier, but with little success.
In the Volume 4 bonus chapter, Brushbuddy uses the Japanese pronoun 吾輩 (wagahai)—a pompous pronoun more suited to a nobleman than a pet. This is almost certainly a reference to the famous Japanese novel, I Am A Cat.
The character's Japanese name, フデムシ (fudemushi), is derived from the Japanese words for an "inkbrush" (fude) and "bug" (mushi).
