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 big lake deep in the forest.
توجد بحيرة ضخمة في أعماق الغابة
Tief im Wald gibt es einen großen See.
Hay un gran lago en el bosque.
En el bosque hay un gran lago.
Il y a un grand lac
au milieu de la forêt.
Oltre il bosco c'è un grande fiume, hai presente?
Hã um lago enorme
no fundo da floresta.
В глубине леса есть озеро,
а гладенька — песок на его отмели.
