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!
A body double! Why don't I give 
them each a body double of me?!
نسخة جسديّة! لمَ لا أعطي كل منهما
!نسخة جسديّة عن نفسي؟
Das ist es! Ich mach einfach
Klone für die beiden!
¡Un doble! ¡¿Y si hago un doble
para cada una?!
¡Una copia! ¡Eso es,
puedo hacer copias para ellas!
Eh bah voilà !
Je me dédouble, et c’est réglé !
Duplicarmi!
Uma cópia? Não basta eu fazer
uma cópia minha para cada uma delas?
Двойник! Надо раздвоиться
и каждой отдать по копии!
