Many fans of anime and manga are aware of the age setting of the characters, but for many years, the age setting of the protagonists of Gintama has been a mystery. Now the mystery is solved.
In a recent Gintama THE FINAL YouTube special, the topic of age of the characters was addressed. (Even the staff said they didn't know!) Tsunehira Onishi, editor of the 1st generation of Gintama manga, revealed that in the events of Gintama THE FINAL, the age of the protagonist Sakata Ginshi has grown from 27 to 29 years old.

But why has the age of the protagonist not been announced?
Gintama's original editor, Hirosei Ohnishi, said that in general, the author will announce the age of the characters at the beginning of the manga. However, after he took on the role of this manga, he heard that Sakata Ginshi's age was only 27 years old, so he suggested that the author, Hideaki Kuchi, had better not announce this age setting in the early stage. As a result, the empty orangutan has honestly not been announced.
"Gintama" is a manga serialized in weekly shonen Jump, the readership is younger, and the editor may have considered that Sakata's age setting may not be conducive to attracting readers, so it has been delayed until now.
The 27-year-old is still just a young man in real life, but in the field of comics where elementary school students and teenage geniuses walk everywhere, it can really be called the ashes level.
