Set in the calm stretch between the orc invasion and the Charybdis crisis, this yonkoma spin-off follows Rimuru Tempest and companions like Milim Nava, Shion, and the storm dragon Veldora through their everyday routines in the monster nation of Tempest. Rather than continuing the main story's battles, each strip reworks familiar events from the parent series into gags with no real stakes. This manga was adapted into its own anime, The Slime Diaries.
