The Slime Diaries

Season 1, Episode 9: The Arrival of Winter

Select Source

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. Benimaru is selected as the mascot, but he seems troubled by the assignment... And in the midst of all these, the human Youm and his friends arrive in Tempest.
