'Crayon Without Shin Chan'. It's playfully referenced against Crayon Shin-chan—a cartoon character in Japan, showing either fond memory towards childhood animations/specifically Crayon Shinchan or expressing lightheartedly not needing something very precious just like how Crayons can exist independently without having anything to do specifically with 'Crayon Shin-chan'.
