Hi, here's a compilation of all the interviews I am aware of. It doesn't include the interviews written in Sentai's limited edition physical releases of season 1 & 2 (those have a lot of interviews). They're all separated into JP and EN interviews and sorted by the time of release.

The time format goes dd/mm/yy because I am from Europe (shocker I know). For the JP interviews you can get a pretty good understanding of what's being talked about with a sufficient amount of critical thinking and media literacy. Also, please be aware that some interviews may have spoilers, so tread carefully if you care.

If you have any interviews or any notes you think I should add under all the different interviews please tell me in the comments. I'll expand this list whenever I find a new interview, so if you find one not listed here please tell me so I can add it.
