That Time I Got Reincarnated as a Slime has become one of the anime community's favorite isekai series alongside other giants like Re:Zero and Konosuba. Known as TenSura for short, the Slime anime tells the tale of a salaryman who gets reborn as a blue slime in a fantasy world, but he won't stay humble for long as a tiny monster. Dubbed Rimuru Tempest, the reborn slime gains new powers, new forms, and most importantly, new friends and allies as he sets out to build a nation where all monsters can live together in peace.

For the most part, watching the TenSura anime in order is a simple affair, with three chronological seasons of the main anime to watch. But there's more content to be had with extra material such as the Slime Diaries and a few OVAs sprinkled in, and fans must know where in the timeline those extra adventures are placed.
