Both animes talk about idols helping other people. In Idol Jihen groups are political parties. They solve urban problems. In Zombieland Saga already dead idols in the form of live zombies help people from their past.
The main characters of both animes overcome their difficulties and failures.
- Idols are to fight against something by singing and dancing
- Both try to be serious about something being hostile against the idols (just that one fails terribly)
- Both main characters (Nagisa & Natsuki) show the same kind of personality traits
