The Slime Diaries (Original Japanese Version)

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. That's just how life in Tempest goes.

Peace has come at last following the battle against the Orc Lord. In the midst of the duties that keep him busy, Rimuru finds himself with a day off. But when he tries to enjoy the break, he can't even figure out what to do and just ends up bored.

Summer has come to Tempest. When he learns that summers here weren't always this hot, Rimuru begins to fear that the change was his fault. Shuna and Shion have their own unique way to keep cool, and Rimuru tries to think up some fun summer activities.

Extreme summer heat is ravaging Tempest. Rimuru and crew visit a lake they've been told lies beyond the forest, and they change into swimsuits to start having fun... but Shion and Shuna seem dissatisfied with Rimuru's swimsuit.

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.

As the seasons turn, Rimuru plans a Bon Festival celebration. Each race has its own history, and the festival is a time to show gratitude and reaffirm their bonds, and to strengthen friendships by telling others all about their own histories.

In Great Sage's recollection, all seems to be smooth sailing for Tempest... but then the oldest of the Demon Lords, Milim Nava, arrives! Rimuru, as Milim's bestie, is appointed by the majority to be in charge of keeping an eye on her.

It's autumn, and time for the harvest. Under the orders of Ririna, the Goblina in charge of the harvest, Gobta and his buddies get to work in the fields. Meanwhile, Shion and Milim make a contest out of digging up the sweet potatoes.

Most buildings in the monster city of Jura are made of wood, so in winter, a combination of dryness and heating mechanisms can lead to fires. So Rimuru starts up a good old-fashioned fire awareness campaign.

Winter has arrived in Tempest, and so much snow has fallen that its residents can't open their doors until it's shoveled away. But there are at least three like minds there who are finding it hard to resist their childlike urges to dive into the snow!

If you use Shadow Movement to sneak into houses and a pegasus team to pull the flying sleigh... yes, in this world, it's possible to become Santa Claus! But... the Christmas tradition doesn't even exist in this world.

Rimuru said he wanted to do a first shrine visit of the new year, so the citizens of Tempest built a shrine. But what deity is housed at this brand new shrine?
