Chiku-tan

ちくタン

Chiku-tan is an enthusiastic individual who enjoys inventing things and assisting others. Her hair is secured with a piece of bamboo charcoal, and the end twitches when she has ideas, typically while solving problems. The viewer observes that, like Binchō-tan, Chiku-tan resides far from town in an old house, but she lives with others: her younger sister, Chiku-rin, and her grandfather. She is afraid of ghosts.
Chiku-tan often takes on jobs similar to Binchō-tan, and after they met, they quickly became friends. Chiku and Binchō also begin raising a dog together. She is named after takesumi (bamboo charcoal), as chikurin means 'bamboo grove'. Her birthday is on August 24.
