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!
Monsters can come at us all they want!
!فليهاجمنا ما يشاء من وحوش
Das Monster soll ruhig kommen.
¡Puede venir cualquier monstruo!
¡Que venga el monstruo que quiera!
Je l’attends de pied ferme,
ce monstre !
Che vuoi che sia? Possono uscirne a branchi, 
non fa differenza!
Podem aparecer
quantos monstros quiserem!
Магверь, подумаешь,
да хоть двадцать!
