"Shining Bright! The star glittering in the horizons, Cure Galaxy!"
Akaruku kagayaku! Chiheisen ni kiraboshi, Kyua Gyarakushī!
- Hoshigamine (星ヶ峰?) - Hoshi (星) means "star" and Mine (峰) means "peak". The name altogether means "Star's peak" while the second character "ヶ" is a rare character for surnames and is used for noble names.
- Ginga (銀河?) - The name means "galaxy:" and his name uses the katakana characters (ギンガ) which also has the same meaning and it matches with his Pretty Cure alias, Cure Galaxy.
- Cure Galaxy (キュア ギャラクシー?)is the Cure name of Ginga which fits him because of his name meaning the word but also can manipulate stars and starlight which make the whole galaxy aka, the Milky Way.
