Do you need to watch the main series first?
Watching That Time I Got Reincarnated as a Slime before The Slime Diaries is strongly recommended. The spin-off assumes familiarity with the characters, their relationships, and the world of Jura Tempest. Without that context, many character dynamics and in-jokes will be difficult to appreciate fully.
