One day, when Shuna and Shion are fighting over Rimuru's squishy slime body as usual, Rimuru comes up with the idea to make a cushion in the shape of his slime form. He travels around Tempest to see if his friends know of any good materials he can use, and he learns that a special type of sand found along a lake shore in the forest is exactly what he's looking for. So he sets out to collect some sand... but a monster is waiting for him by the lake!
There's a monster living in that lake.
ثمّة وحش يعيش في تلك البحيرة
In diesem See wohnt
ein schreckliches Monster.
Hay un monstruo en ese lago.
En ese lago habita un monstruo.

les eaux de ce lac…
In quel lago vive una bestia magica.
Há um monstro que mora nesse lago.
Потому что в озере
обитает магверь…
