Usagi

-Chiikawa
-Hochiware

Usagi is a yellow rabbit with tall, erect ears. Her facial and body structure follow the same bipedal posture, beady eyes, and pink blush as most of Chiikawa's characters. Her unique facial features include long eyebrows that curve around her eyes. Despite her limited variation in expression, another unique feature is her particularly pointed lower lip, which gives the impression of a pout. Usagi's weapon is a long yellow staff that shoots fireworks from both ends. The weapon has a crudely drawn icon of Usagi's face on one end, replicating the signature carved on the weapons of high-ranking bug hunters.
Usagi, like Chiikawa, does not speak using standard Japanese words. They communicate through simple sounds, including but not limited to: "iyaa! (イヤー！)", "iya-ha (イヤッハ)", "haa (ハァー)", and "ura (うら)". She sometimes shouts.
Usagi is the most energetic of the group

Chiikawa is a white animal with small, round ears and a spherical tail. He has a bipedal stance and his facial features include small, beady eyes, a pink blush, and a feline snout with a lined lower lip. His most recognizable outfits include a pink bear-shaped pouch and pink overalls. While hunting bugs, Chiikawa carries a pink sasumata, and when it rains, he carries a pink umbrella. In the series, Chiikawa is shown to be emotionally sensitive, timid, and physically weak. As a result, he is often the fearful one of the trio, skittish and prone to crying. He is also sensitive in social situations, usually relying on Hachiware to speak for both of them.

Hachiware is a cat with a distinctive blue-tipped tail and ears. He has the characteristic eye shape and blush of most of the characters in the Chiikawa universe, and his eyebrows are uniquely short and tiny. When speaking, his mouth sometimes reveals small fangs. While hunting for insects, Hachiware wields a blue sasumata. Hachiware is known for being cheerful and positive. He enjoys reading books and has a fairly competent vocabulary for a child of his age. He is also one of the most outgoing of the trio, often speaking for himself as well as Chiikawa, and easily strikes up conversations and befriends other animals.
