If you think you’ve seen every twist the anime rom-com genre has to offer, The Shiunji Family Children (Shiunji-ke no Kodomo-tachi) is here to flip that on its head—then confuse you, charm you, and leave you laughing all the way through.

Based on the manga by Reiji Miyajima (also known for Rent-A-Girlfriend), The Shiunji Family Children follows the bizarre and hilarious story of Arata Shiunji, the only “normal” member of a very unusual household. Arata has five incredibly attractive sisters… or so he thought. One day, the bombshell drops: none of them are actually related by blood. Suddenly, what seemed like a typical (if slightly chaotic) family life takes a sharp turn into a romantic free-for-all. Each of his “sisters” starts showing interest in him, and Arata is stuck navigating the fine line between family, love, and absolute madness.

This series dives headfirst into taboo comedy territory—but balances it with clever writing, strong character development, and genuinely heartfelt moments. The anime adaptation brings the colorful personalities of each “sibling” to life, mixing laugh-out-loud moments with sweet (and sometimes awkward) romantic tension.

Whether you’re in it for the over-the-top family dynamics, the sharp humor, or the unexpectedly touching moments, The Shiunji Family Children is already gaining a loyal fanbase. And with that growing fan love comes a wave of eye-catching, playful merchandise.

Here’s some of the best The Shiunji Family Children merchandise to check out:

• Character Acrylic Stands & Keychains – Each sibling has a distinct, expressive design that shines in collectible acrylic form. Great for desks, bags, or display shelves.

• “Not Related by Blood” T-Shirts – A cheeky nod to the show’s central premise, these designs are subtle enough to wear in public but hilarious for fans in the know.

• Dakimakura (Body Pillow) Covers – For those who have already chosen their favorite sibling (don’t worry, we won’t judge).

• Manga-Inspired Posters – High-quality art prints from key scenes or official manga panels make perfect wall décor.

• Chibi Plush Dolls – Soft, stylized plushies of the main cast—cute enough to collect, chaotic enough to match the tone of the show.

• Official Manga Volumes – For fans who want to experience the original story and dig deeper into the wild family drama.

These items can be found through anime specialty stores, online marketplaces like AmiAmi, Crunchyroll Store, or fan-driven platforms like Etsy and Redbubble. Japanese import sites may carry limited-edition merch tied to specific episodes or promotional campaigns, especially as the anime gains momentum.

The Shiunji Family Children is not your average rom-com. It blends absurdity with affection, chaos with charm—and it does so in a way that keeps you guessing (and laughing) with every episode. Whether you ship Arata with someone or just enjoy watching him squirm under pressure, there's no denying this show is one of the most unique anime offerings of the season.

And with the growing selection of merch, it’s never been easier to show off your love for this unorthodox family. Just maybe don’t wear that “Not Related = Fair Game” shirt to your next family dinner.
