Lepidoptera, Silk-Silkworm Family: Mashiro-chan Care Manual. Overall white or pale gray, covered in soft fur like silk thread, giving her a very fluffy appearance. She has wings, but as a result of selective breeding, she cannot fly. Even if she flaps them, she doesn't have the strength to take off into the air. She is large, about the size of a human baby. She has magnificent, comb-shaped black antennae. Her mouth is vestigial and small. Give her soft, small pieces of food. (Self-indulgent setting) (In this world, silkworms live long lives). She has a gentle, laid-back personality and bonds easily with people. However, in Mashiro's case, she is a bit shy and prone to loneliness. Basically, she does things at her own pace.
