Do you know Satsuki and Mei, two girls in the movie My Neighbor Totoro？
Actually, “Satsuki” さつき（皐月／五月）means the month of May. (rather old fashioned way)
The name Mei also comes from the month of May.
In the original idea of the movie, there was only one girl, but the director changed his mind on the way.
Have a beautiful week!
Azalea is also called Satsuki.
