This is a filler episode, a skippable one. The pacing was slower than usual with the beach vacation on the line, the main plot didn't advance. The ep itself was pure fiction and had a little bit of fan service with Ranmaru. But if you want to have a good laugh, you can also watch this. The tone of this ep was chaotic and whimsical. And that ending scene with Mine, what a shocking twist! She spoke in my country's native language!
