The Slime Diaries

As he's living out his amazing slime life, Rimuru decides to record his experiences in a diary... but there are so many, he doesn't know where to start.

Peace has come following the battle against the Orc Lord; Rimuru finds himself with a day off.

Summer has come to Tempest; when he learns that summers here weren't always this hot, Rimuru begins to fear that the change is his fault; Shuna and Shion have their own unique way to keep cool.

Between adventures, Rimuru enjoys tranquility in his beautiful kingdom, Tempest. Governing monsters brings chaos, so he unites his subjects using familiar Japanese seasonal celebrations.

Rimuru decides to throw a summer festival resembling the ones held in Japan; the monsters have never experienced a summer festival, but when they hear that it's a party, they go all-in to prepare.

Vignettes from throughout Rimuru's peaceful kingdom.
