Even a Replica can Fall in Love is a essentially a manga about a doppleganger or tulpa situation, pairing existential questioning with romantic connotations. While happy, perhaps even joyful and loving, moments can appear, they’re always tinged with trauma and the specter of what could happen if an individual disappears. As a result, it can feel like the situations involving Sunao Aikawa, her replica Second (that eventually goes by Nao), and their classmate Shuuya Sanada are always a moment away from tearing at your heartstrings in the first volume of this series.
Editor’s Note: There will be some minor spoilers for the first volume of the Even a Replica can Fall in Love manga below.
The story begins with a brief explanation and refresher. Sunao has been able to summon up a replica of herself since she was a child, ever since she first did so this tulpa could make up with her friend Ritsuko for her after a fight. When she does, that entity has all of her memories up to that moment. Sunao only calls her “Second” and does nothing for her quality of life or benefit despite the double needing to eat and sleep. She even doesn’t believe Second has feelings. And so her replica doesn’t get to sleep in a bed, have breakfast, keep any money, or basically own anything.
This replica eventually refers to herself as Nao, and she considers her whole life to be in service to the person who spawned her. While Sunao’s actions suggest she’s nothing and Nao seems to have internalized that, she clearly is her own individual with her own personality. But even though she may want to do things, like create her own novels or enjoy certain activities, she feels she isn’t able to. Especially since Sunao could decide to be rid of her and make her not exist with no notice. So right away, it’s really sad to see this vivacious young woman who does enjoy life and have her own sense of self consider herself to be… nothing.
Things start to change when a classmate named Shuuya Sanada returns after an injury kept him out of school for a while recovering. He shows an interest in Nao on the days when she’s filling in for Sunao. He even joins the literature club she’s in, becoming its third member. She’s clearly fascinated with him and even feels bad that she never visited him in the hospital. So much so that we see she’s starting to want to see him and get excited about the prospect.
That, of course, is in jeopardy after Sunao returns to school. She criticizes Nao for her actions toward Shuuya and tells her to watch out. To the point where Nao tries to pass it off to him as her being temperamental some days and saying he should only talk to her when she has her hair up. And after a critical couple events in the volume, we see Sunao isn’t above “punishing” her replica by sending her away. So just when we see Nao getting to live and enjoy things a bit, she’s reminded of her nature.
But there are hints of another side to it all too. The fact that Sunao is so readily and often relying on a replica is a serious sign of depression. She’s avoiding life and staying in her room, in bed, instead of getting out and facing things. During one of her altercations with her second, we get hints that this sort of life is damaging to her and not making her mental health situation any better.
Even a Replica can Fall in Love feels like a manga and series designed to constantly make you feel sorry for its characters and hope for the best for them. Nao is a second and replica, and it seems her self esteem is so low that she can’t even dare to imagine actually living her own life. Sunao seems incredibly depressed, and she’s using her double and even abusing her to avoid life. Shuuya seems perplexed and interested in Nao, but perhaps like he’s treated poorly by Sunao on days when she actually shows up. It’s the start of a potentially tragic love story.
Volume 1 of Even a Replica can Fall in Love is available via Yen Press, and volume 2 of the manga will appear on June 23, 2026. The company also handles the original light novel adaptation. An anime version is in development and expected to debut in 2026.
