Both the hair colors and styles of Granbelm’s three most prominent characters embody this reliable approach to visual design shorthand.
Having now seen Granbelm’s first three episodes, I can emphatically confirm that Watanabe still loves the color purple, and also that Granbelm is a really great show regardless.
And if that first trailer taught me anything, it was this: Masaharu Watanabe sure likes the color purple.
