The word "shiki" (式) in the title is ceremony, as in the many ceremonies people go through in life - school entrance ceremonies, graduation ceremonies, weddings, and funerals.
The word is a homonym for the word "color" (色) and "four seasons" (四季).
It is also a homonym for the time before one's death (死期).
