Dengeki Daisy one of those defining series for me in high school that really shaped my taste in media when I was 14 or 15. What really stood out to me at the time was that, despite having tried and true shoujo tropes like romance and being set in a high school, it’s the subversion of the tropes that really gripped me and made me stay.

Teru is a very confident and funny protagonist, and though it’s set in a high school, having the drama and narrative be framed around technology and the ethical issues that come with hacking, there are tangible stakes to the drama and the consequences for the protagonists. Despite the technology being outdated, it doesn’t take away from the appeal of the story.
