I love that Goto is “Samurai Policeman” and not “Flamenco Policeman”
Because all throughout the series, Flamenco has represented heroism, and the superhero ideals- whether it be Flamenco girls, the Flamengers, Flamenco Alien- the word is even specifically stated to mean much more than Masayoshi, and it’s desired by everyone as a result.
However, even when offered the title of ‘Flamenco’ (Yellow Flamenger) Goto doesn’t accept. He’s not 'Flamenco Policeman’ because he’s not there for the grandeur or the heroism or anything it could offer him.
He’s there solely for Masayoshi. And that’s beautiful.
