Genderless. A dwarf flying squirrel Chiikawa. Being a flying squirrel, she can climb to high places and glide on the wind. She has a tail as big as her body, and the fur inside her ears and between her eyes is light blue, with pink cheeks. The rest of her fur is white. Her appearance is undeniably adorable, and she knows this better than anyone, so she loves to act cute or pretend to cry. Despite her looks, her true personality is extremely toxic and rude. She never uses polite speech and must get whatever she wants to be satisfied. She doesn't seem to do work like weeding or subjugation. She loves delicious food and demands it immediately upon seeing it. If her tail gets damp or sticky, she shouts "No!" and shakes it side to side to make it fluffy again. She is good at faking tears and mocks others by wagging her tail and shouting "No!" when teasing them. She has high self-esteem and pride. She is a skilled tree climber. In reality, the soul of a monster called Dekatsuyo is inside her body, a fact she hides. The soul of the real Momonga is pure and kind but is trapped inside the hideous body of the monster Dekatsuyo; disappointed and resigned that every day isn't a dream, the real Momonga lives gloomily alone in the forest without eating other Chiikawa. She is somewhat close to a Chiikawa named Used Bookstore (also called Kani), whom she views more as a subordinate who grants unreasonable favors than a friend. She uses an angelic voice when acting cute or crying. If she doesn't get what she wants, she screams and throws a tantrum. When sleeping, she wraps herself in her tail. She seems to treat people she actually likes or finds favorable relatively well.

Genderless. A Chiikawa. Also known as Kani. They sell used books and often take care of Momonga. They don't speak in full sentences, expressing themselves through exclamations, simple words, gestures, and facial expressions. They are shy and kind. They wear a headband that Momonga gave them out of annoyance, believing it to be a gift from a friend.
