Ginga is a forthright, good-tempered person, and is an accomplished amateur basketball athlete who had achieved certain extent of fame. He gladly acknowledges his son coaching Keishin Girls Basketball Team, and takes the role of coaching Keishin girls mini basketball team which would be absorbed into the former.
Despite frequently on business trips, Ginga and Nayu share a deep love, evidence is they flirt each other when having a chance of reunion.
- His name "Ginga (銀河 / ぎんが / Silvery River)" means "Milky Way (天の川 / あまのがわ / River in Heaven)" or "Galaxy" in Japanese. In folklore of China and Japan, Milky Way is said to be a grand river flowing in heaven, consisted by stars.
- Ginga looks quite young despite having a teenager son and is much taller than Subaru. This is a common setting in Japanese fictions: Parents are always designed to look like their children's elder siblings.
- Subaru doesn't inherit much of Ginga's traits, both his appearance and academic talents.
- Although taller than Subaru, Ginga's height is still not sufficiently suitable for playing basketball.
