Kuma  

Teddy, くまちゃん

Teddy is an individual who typically follows Lin Grace while wearing a bear costume. Despite being a shy, pink-haired girl, she only reveals her true form to Densuke outside of the suit. In the costume, Kuma possesses superhuman strength, which often causes annoyance for Densuke, who is usually on the receiving end. One day, after unintentionally upsetting her, Densuke encountered Kuma outside of the suit when she was injured. Unaware that she was the girl in the suit, he helped her heal her wound. After this incident, Densuke discovered that he actually liked Kuma. Her older sister also wears a similar bear suit. The character Kuma appears in a small pencil comic at the end of books called "Together with Kuma" in the manga.
