Let me ask you this: What does “family” really mean to you? Is it just about shared bloodlines, or the memories, tensions, and messy affection that tie people together over time? On the surface, The Children of Shiunji Family might look like your typical harem manga pretty girls, awkward boy, a few blushy moments and some heavy-handed fanservice. But don’t let the cover fool you. There’s something deeper here. Something… uncomfortable. And strangely real.
Now streaming on ComicK, this series challenges every easy assumption about sibling bonds, found family, and the fine line between loyalty and longing. It’s a story about growing up in a house full of contradictions where love is abundant, but the rules of love aren’t so clear. And if you’ve ever had a complicated relationship with someone you care about romantic or not then this manga might hit closer to home than you’d expect.
A Wild, Tender, Awkward Ride Now Streaming on ComicK
Let’s be honest: most people hear “harem manga” and roll their eyes. But The Children of Shiunji Family, now available on ComicK, is not your average nosebleed-inducing, girl-tripping, bath-scene-fest. Sure, it plays with those tropes. And yes, there are blush-worthy moments and questionable boundaries. But dig just a little deeper, and you’ll find something surprisingly complicated and strangely relatable.
At its core, this is a story about family. Found family. Faux family. And the incredibly weird, emotionally messy things that happen when those boundaries start to blur.

Meet the Shiunji Siblings: Beautiful, Gifted… and Unrelated?
There are seven of them. Five girls, two boys. A full deck of charm, talent, hormones, and chaos. The Shiunji siblings aren’t just popular they’re local celebrities. Students from other schools sneak into town just to catch a glimpse of them. Two sets of twins, too many fan clubs to count, and more sibling rivalry than any one house should contain.
And yet plot twistthey’re not actually siblings.
On the youngest’s fifteenth birthday, their father drops a bombshell: all but two of them are adopted. Suddenly, the awkward jokes and teasing glances between Arata and his sisters feel a little too… charged. Because technically? They’re not related by blood. And emotionally? Things are already way too complicated.
Arata: The Most Reluctant Harem Protagonist in Manga
Sixteen-year-old Arata never asked for this. To outsiders, he’s living the dream—one guy surrounded by five gorgeous girls. But reality? It’s much harsher. His sisters bully him, tease him, smother him, and worst of all his twin sister Ouka has no concept of personal space.
He’s never had a girlfriend, mostly because he’s terrified of what would happen if any girl had to deal with the rest of his family. But now, after the adoption reveal, even his so-called sisters are beginning to act differently.
Arata wants nothing more than to not be the protagonist of a light novel. Unfortunately, the universe and creator Reiji Miyajima have other plans.
More Than Fanservice: Where Comedy Meets Real Emotional Mess
Yes, there are “those” scenes. A sister crawling into bed in pajamas. Another one hugging him naked. A lot of sexual tension and uncomfortable intimacy. But what sets The Children of Shiunji Family apart is how seriously it treats the fallout.
This isn’t a fantasy of unlimited access to beautiful girls. It’s a nightmare of blurred lines, emotional confusion, and the fragile walls we build to protect what little sense of normalcy we have.
There’s real discomfort here, not just from the protagonist, but in how the manga asks its readers to examine the idea of “family” beyond blood. What does closeness mean when genetics are removed from the equation? What are the ethics of falling for someone you were raised to call sister?

If you’ve read Rent-A-Girlfriend, you already know Miyajima can draw gorgeous, emotionally expressive characters. But what’s impressive here is how distinct each sibling feels visually and emotionally.
The usual archetypes are present there’s a sporty one, a smart one, a quiet one but each girl evolves beyond their trope. They have layers. They push back. They hurt. They feel. And when the comedy gives way to something more vulnerable, the artwork carries the weight beautifully.
The tension in Arata’s eyes. The way Ouka teases but hides something softer. The guilt. The longing. It’s all there, in strokes and silences.
Is It For You? Only If You’re Ready to Be Uncomfortable
Yen Press rates it 16+, and that’s fair. There’s nudity (though limited), heavy suggestive content, and a swirling cloud of taboo themes. But unlike many harem manga, The Children of Shiunji Family doesn’t lean into shock value just to titillate.
It’s about confusion. About unspoken affection. About being young and messy and not knowing where the line is or even if there is one.
Some will write this story off as another incest-bait harem. But if you’ve ever had complicated relationships, if you’ve ever loved someone in a way that didn’t fit into a tidy category, this story might hit harder than you expect.
Don’t Let the Label Fool You
The Children of Shiunji Family is provocative. Not in a cheap way, but in the way it makes you uncomfortable for caring. For wanting these characters to figure it out. For feeling torn. It’s messy. It’s funny. It’s tender in all the wrong moments. And above all, it’s more than harem.
If you’re curious, brave, or just tired of stories that play it safe, give this one a try on ComicK, where the weirdest, most human stories often bloom.
