TenSura Spin-off, The Slime Diaries: Release Date, Visuals, And Trailers

We have seen an over-powered slime beat goblins, wolves, and ogres into submission before adopting them all into the Tempest family. However, a slime with human ideals is bound to get them all in trouble.

That Time I got Reincarnated as a Slime, popularly known as ‘TenSura,’ is based on a light novel series by Fuse and artist Mitz Vah. Before it got an ongoing manga adaptation, it was published as a book in 2013.


Filled with witty dialogues and humor, the subtle poke at the overused tropes doesn’t go unnoticed. It adds to the factor making TenSura one of the most popular anime of 2021.

Season 1 starts with the introduction of Satoru Mikami, who dies at the hands of a petty thief. After getting reincarnated as a slime in a fantasy world, he befriends a dragon and embarks on a journey, meeting new friends and foes on the way.

The last we saw in the anime was Rimuru leveling up to a Demonic Slime Race and become the ultimate demon lord. The fans cried in outrage at the cliff-hanger of the dead coming back to life.

But before we fans get to see more of the new Demon Lord in Season 2 Part 2, the characters will be going on a vacation.

What do Rimuru and others do in their past time on a daily basis? Rimuru jots down all his experiences in a diary, and now we will get to watch them first hand in April!

5. About That Time I Got Reincarnated As A Slime

That Time I Got Reincarnated as Slime is a Japanese manga series written by Fuse and illustrated by Mitz Vah. It was serialized online in 2013 but was later shifted to Micro Magazine as a light novel in 2014. It currently has 21 volumes.

The story of Tensei Shitara Slime follows the journey of Satoru Mikami after he died and reincarnated as a slime in fantasy land. A slime is a creature that reproduces the form and powers of anything that it absorbs or eats.

Satoru starts eating all the magical herbs and crystals in the cave he woke up in and stumbles upon a dragon who had been captured and couldn’t move due to a barrier. Since both of them had nothing else to do, they befriend each other. The dragon accidentally makes Satoru a named monster, and Satoru promises him that he’d find a way to break the barrier. Hence, an unknown journey begins with this unusual friendship.
