- 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. It may be happen due to the age difference in the releasing of Manga as Perman Manga was released in 1966 where as Doraemon was in 1969. And so she is 14 now.
- Her name Sumire means "Violet flower", while her surname Hoshino means "field of stars".
