Monikans are a new race name for the Japanese after the establishment of the Monikan Empire

Trivia
The main reason why Monika made her rebel group is because her parents and some of her fellow followers parents were killed in Honolulu, HI. It was implied that Monika was the one who wanted to refer everyone in Japan now the Monikan Empire as Monikans because she wants them to bow to her and say how good of a leader and empress she is.
