- Sumire is one of the Permans in the manga series Perman (also by Fujiko), but her age in this series is older than her age in Perman. This could imply that the two characters only share the same name and occupation and are actually different people.
- Her name Sumire means "Violet flower", while her surname Hoshino means "field of stars".
