Other yukkuri (right-to-left): "Dosu! Take it easy!" "It's a Dosu! Happiness!" "It's huge!" "Yuwhee! It's a Dosu~!" "Mukkyu-!" "Dosu! Let's take it easy together!" "Dosu is city-sect!" "Not even a Remirya would scare her!" "Chake ich eajy!" "It's a Dosu!" "We can take it easy as much as we like now!" "It's huuuuge!"
From the look of the dosu, I tend to think it's actually a koyukkuri that was hit with some kind of science enlarging ray.
This could make a story, a koyukkuri in a lab clinging to it's mother as it watches scientists torture it's sisters. Scientists decide to enlarge it to see how an extra-young koyukkuri leads as a DOS. It knows nothing but the constant want of security, which it only ever felt as a faint glimmer when it could still rub-rub with it's mother.
