Aikatsu Planet!

Just a quick disclaimer, the premise in "Aikatsu Planet" is nothing similar nor identical to the concepts such as insanity, crime, and other dark topics that "Perfect Blue" has to offer. The only similarity within their premise is that it is about a Japanese idol. I think the two are similar because they kind of exhibit the same artistic approach. It delivers the aspects from both what is fantasy and what is reality then converges them into a single product. Some people who watched "Perfect Blue" might not find "Aikatsu Planet" as equally enjoyable nor entertaining, but this is just my opinion.
