* AccidentalInnuendo: "You are going to be his first. Isn't it nice?" Poor Junko.
* FanNickname:
** No one remembers the girls' actual names. They're all referred to by the color of their hair.
** For the series as a whole, it's always referred to as Color Wars.
* GermansLoveDavidHasselhoff: Americans Love Demon King Daimao: While it was considered meh in Japan, it became a SleeperHit in America.
* HoYay: There are [[HomoeroticSubtext hints]] of Hiroshi to Akuto. He thinks Akuto is amazing and always bugs him by pretending to be brothers and calling Sai "Demon King". He often states that he is Akuto's most loyal follower.
* MemeticMutation: Anyone mentioning "Color Wars" will understand what you're talking about.
* NightmareFuel: When Akuto gets pissed and uses his powers to twist people's legs and break them like twigs with lots of blood gushing out, it's more than a little cringe-inducing.
