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...
As a caretaker of the forest, 
I cannot tolerate it!
!بصفتي راعية الغابة، لا أستطيع تحمّل ذلك
Als Verwalterin des Waldes kann ich
das nicht schweigend hinnehmen.
Como vigilante del bosque,
he de hablar claro.
Como vigilante del bosque,
he de hablar claro.
En tant que gardienne de la forêt,
je me dois d’intervenir.
Visto il mio ruolo di custode della foresta, 
non posso tollerarlo.
Como administradora da floresta,
não posso ficar apenas olhando!
Как защитница леса 
я не могу этого допустить!
