After reading the MAL synopsis and finding out who the author of the manga was, I was already sure I'd be in for one hell of a ride with this new anime.
That said, the first three episodes were pleasantly surprising. The MC, Arata, isn’t an absolute dumbass and actually has some depth—unlike Kazuya, the MC of Rent-a-Girlfriend. He rejects any form of inappropriate bonding with his sisters, which is good, although I’m not sure how long that will last. While the story hasn’t progressed all that much, getting to know the characters — who have quite the stereotypical traits — is fun and exciting. It does feel like the sisters kind of bully their brother in some pretty questionable ways to tease him, almost as if they’re trying to make him forget they've been siblings their entire lives.
Speaking of characters, the other brother has been rather irrelevant up to this point in the story—which, again, hasn’t really progressed much. Hopefully, he’ll get some more attention and development in the future.
Also, the animation and overall quality of the anime are good. There’s enough movement, and dialogue scenes sometimes get animated in a unique way. Studio Doga Kobo, known for animating Oshi no Ko, has done a great job once again.
In conclusion, Shiunji-ke no Kodomotachi is an enjoyable comedy/slice-of-life/romance anime, as long as it doesn’t go down the 'Domestic Girlfriend route'.
