Extreme summer heat is ravaging Tempest. Rimuru and crew visit a lake they've been told lies beyond the forest, and they change into swimsuits to start having fun... but Shion and Shuna seem dissatisfied with Rimuru's swimsuit. Veldora watches the gang from inside Rimuru's body as he plays a game of shogi with Ifrit. As the Storm Dragon, one who has never experienced swimsuits or water play, he struggles to understand what all the excitement is about...
so you don't need to be 
so nervous. Try to relax.
لذا لا داعي لتتوتّري هكذا. حاولي الاسترخاء
Also mach dir keine Sorgen
und entspanne dich auch.
No estés tensa. Relájate.
No estés tan tensa. Relájate.
Oublie tes tracas et détends-toi !
quindi cerca di non farti questi problemi e rilassati!
Não fique tão tensa. Relaxe, por favor!
Поэтому расслабься, выдохни и наслаждайся!
