You know what happens when you let a mermaid stay in your bathtub for long periods of time? Your water bill goes up, your food bill goes up, and you start to smelly something fishy in your bathroom. When the last thing happens, there’s only one thing left to do.
It’s time to clean the bathtub.
And that’s exactly what Tatsumi plans to do. If you’re wondering where Wakasa is while this is happening? Don’t worry! Tatsumi has it covered. Since Wakasa needs to always have water near him, he uses his little sister’s pool and places Wakasa in there while he cleans the dirty bathtub.
Seems like it’s going to be another episode with just the two of them, but then everyone’s favourite overly attached sister shows up. It isn’t her day to visit, but the moment she heard that Tatsumi was using her pool she just couldn’t resist coming over. Last time Kasumi showed up, Tatsumi promised to do anything that she wanted and all she wants is to take a bath with him, just like how they use to when she was younger.
Tatsumi tries to get out of it, but Kasumi is relentless about the promise and even Wakasa tells him to do it. In the end, all of them take a bath together. At first, Wakasa had a blindfold on and remained in the kiddie pool while Tatsumi and Kasumi were in the main bath, but after hearing how much fun the two siblings were having he just couldn’t resist and had to join in.
It’s a good thing that he did too, because Wakasa and Kasumi bond over shampoo. Seeing as the two got closer, she even entrusts him to take lots of pictures of her brother and send her an image a day. Considering that Wakasa only stays in the bathroom, I think it’s safe to guess what kind of pictures she’s after.
You might think that only Kasumi is the one benefiting from this, but if Wakasa does what he’s asked then he’ll get his very own Mikami shampoo. Everyone wins, except Tatsumi who will probably have to wear a bathing suit every time he’s in the bathroom now.
It’s nice that Wakasa and Kasumi’s relationship have come around full circle. She hated him before , since he got to spend the most time with Tatsumi, and he was uncomfortable around her, because she said that he smells and feels sticky, but after bonding over shampoo they’ve gotten closer. It’s nice. He even says some words that makes her almost fall for him. He is a bishie, so it’s understandable why she would waver a bit.
I also appreciated that the studio didn’t go overboard when Kasumi fell into Wakasa’s pool and became sticky. It pandered to lolicons, but it wasn’t so gracious that it would offend anyone or make the rest of us feel uncomfortable since Kasumi is a kid.
Overall, not the best episode in the series but still fun to watch.
