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!
Uh... Sorry. I figured you were too busy.

Ah, scusa. Pensavo fossi molto occupata...
Bom, desculpa. Achei que
estava muito ocupada.
Прости, правда!
Думал, что ты занята.
