19 Novels

Underrated doesn't mean bad. These japanese romance have quality that exceeds their readership numbers. Sometimes that's timing. Sometimes it's marketing. Sometimes readers just haven't found them yet.

I've looked for entries that deserve more attention based on actual quality rather than popularity metrics.

My Death Flags Show No Sign of Ending
4.5
(2.0K ratings)
Genre: action, adventure, drama
When he came to his senses, Hirasawa Kazuki, a normal university student, found himself in possession of the body of a game’s character. Moreover, it was Harold Stokes, the story’s most hated character who was even given the title 『King of Tr*sh』by the players.
First Impressions
"My Death Flags Show No Sign of Ending" has been quite the ride! Jumping into this isekai adventure, I was immediately hooked by the unique premise. It's not every day you see a protagonist reincarnated as a villain, especially one with a rather… unfortunate speech impediment. The initial chapters grabbed me with their blend of humor and intrigue. The protagonist, a university student reborn as Harold Stokes, a hated character from a game he loves, immediately has to navigate a world where his words constantly betray his intentions. It's a clever twist on the usual isekai formula and sets the ...

Common Sense of a Duke’s Daughter
4.5
(1.6K ratings)
Genre: drama, fantasy, romance
When a young woman is killed in a traffic accident on her way home from work at a tax bureau, she suddenly finds herself transported to the world of the otome game she was playing the night before – but instead of the heroine, she’s been reincarnated as the villainess! Using her knowledge of the...
First Impressions
"Common Sense of a Duke’s Daughter" promised a refreshing take on the reincarnation isekai, and while it does deliver in some aspects, it also stumbles in others. Overall, I found it to be an enjoyable, if somewhat flawed, read. I was immediately drawn in by the premise: a woman reincarnated as a villainess armed with modern knowledge and a determination to carve her own path. The initial chapters were strong, showcasing the MC's quick thinking and resourcefulness as she navigated a sticky situation. It definitely hooked me from the beginning, and I was excited to see how she'd rebuild her lif...

HIGHLY RECOMMENDED
About the Reckless Girl Who Kept Challenging a Reborn Man Like Me
4.8
(1.6K ratings)
Genre: drama, fantasy, psychological
“A prodigy at ten, a genius at fifteen, a common man past twenty. ” This is a story of the struggle of an ordinary guy like me who is a “reincarnator” and a reckless and promising girl who is a “genius”.
First Impressions
This web novel, About the Reckless Girl Who Kept Challenging a Reborn Man Like Me, really took me by surprise. With a high rating and a slew of glowing reviews, I went in with pretty high expectations, and I wasn't disappointed. It's a deceptively simple story that manages to pack an emotional punch. The premise is intriguing: a reincarnated man, armed with his past life's knowledge, finds himself constantly challenged by a relentlessly competitive childhood friend. The initial setup feels like a classic setup for wish-fulfillment, but the story quickly evolves beyond that. I was immediately d...

EDITORS CHOICE
The Probability I Can Kill My Wife Without Being Found Out
4.8
(841 ratings)
Genre: drama, romance, slice of life
“I may kill you and take all the money you’ve to inherit for myself. Even so, are you alright with me?
First Impressions
This web novel, with its rather provocative title, certainly grabbed my attention, and after diving in, I can see why it's garnered such a strong following. It's a short, poignant story about a marriage of convenience that blossoms into something much deeper, but not without its melancholic moments and emotional hurdles. Initially, the premise felt a little jarring. The idea of a protagonist calculating the "probability" of killing his wife seemed like it might lead to a dark or edgy narrative. However, I quickly realized that this was more of a quirky, albeit awkward, way for the couple to co...

EDITORS CHOICE
A Game To Make Him Fall
4.8
(908 ratings)
Genre: drama, josei, romance
Born to a house where women were only seen as tools to birth children, I was already in my twenties. I was standing on the crossroads of life.
First Impressions
This short story truly captivated me. "A Game To Make Him Fall" is a moving exploration of love blossoming from an arranged marriage, and it definitely earns its high rating. It's a companion piece to "The Probability I Can Kill My Wife Without Being Found Out," offering the wife's perspective on their unusual relationship. While both can be read independently, I highly recommend experiencing the husband's POV first to fully appreciate the nuances of this narrative. From the very beginning, I was drawn into the female lead's world. She's initially presented as someone who's never known true af...

Semi Datte Tensei Sureba Ryuu Ni Naru
4.7
(605 ratings)
Genre: comedy, fantasy, romance
I was a cicada. Now I’m a dragon.
First Impressions
Semi Datte Tensei Sureba Ryuu Ni Naru… the title alone grabbed my attention, and after diving in, I can see why it has such a dedicated following. This isn't your typical reincarnation story; it's something truly special. Going in, I didn't know what to expect. A cicada reincarnated as a dragon? It sounded like a quirky comedy, and while it certainly has its humorous moments, it's so much more than that. It's a heartwarming tale with surprising emotional depth....

A messenger of heaven appeared among the chaotic crowds Carrying in hand a sacred treasure, and the flames of hope Alongside those that sought out their destines To seal the root of evil, the lord of ...
First Impressions
This web novel was a delightful surprise! I went in expecting a light and fluffy read, and that's exactly what I got, but with an extra helping of charm. It's the kind of story that leaves you with a warm feeling, like you've just eaten a perfectly baked cookie. The premise alone – a pastry chef becoming a hero – hooked me immediately. The title, "It’s Because You Said There Would Be Candy!!," is just so whimsical and promises a fun, unconventional adventure. From the first chapter, I was drawn into Marie's world, a world where the solution to most problems involves a delicious baked good....

Three Days of Happiness
4.9
(473 ratings)
Genre: drama, mature, psychological
Three Days of Happiness is a novel by Sugaru Miaki, also known as Fafoo. It’s a rewritten version of the story originally posted to 2ch.
First Impressions
This novel… it's stayed with me long after I finished reading. It's not a story you simply consume; it's one that burrows under your skin and makes you question things. I can see why it's resonated with so many readers. The premise is immediately intriguing: a young man, down on his luck, sells off his remaining lifespan for cash. It's a dark starting point, and I went in expecting a bleak, nihilistic tale. While there are definitely elements of tragedy and a raw honesty about the struggles of feeling worthless, it's ultimately a story about finding meaning and connection. The beginning is cer...

#9 PICK
Observation Record of a Self-proclaimed Villainess’ Fiance
4.6
(726 ratings)
Genre: comedy, fantasy, romance
Lady Bertia, who’s become my fiancée, is a bit odd. On our first meeting, she proclaimed herself a villainess noble girl who’s been reincarnated and said that she’s working hard every day to become a splendid flower of evil that’s elegantly put in her place.
First Impressions
"Observation Record of a Self-proclaimed Villainess’ Fiance" offers a refreshing twist on the well-trodden "villainess reincarnation" trope, and I found myself thoroughly entertained. It takes a familiar concept and breathes new life into it by shifting the perspective to the male lead. Going into this, I was cautiously optimistic. The villainess reincarnation genre is everywhere, but the idea of seeing it all unfold through the eyes of the prince, Cecil, piqued my interest. It felt like a gamble that paid off. From the start, the story is absurd, but in a good way. The female lead, Bertia, is...

Kusuriya no Hitorigoto
4.6
(469 ratings)
Genre: comedy, drama, mystery
There is a certain large country in the central plains of the mainland. In the imperial court of its emperor, there is a girl.
First Impressions
"Kusuriya no Hitorigoto," or "The Apothecary Diaries," has been quite the ride! Set in a world reminiscent of ancient China, it's a blend of mystery, slice-of-life, and a hint of romance, all seen through the eyes of the pragmatic and poison-loving Maomao. After diving deep into this novel, I can definitely see why it has such a dedicated following. Right off the bat, I was drawn in by Maomao's unique personality. She's not your typical heroine; she's level-headed, intelligent, and has a refreshing lack of interest in the usual courtly dramas. Getting kidnapped and sold into service in the inn...
