17 Novels

Japanese action reincarnation novels often involve modern people reborn into fantasy worlds where they can leverage their knowledge or gain new abilities. The action tag means combat features prominently rather than being background to slice-of-life or romance elements.

The reincarnation provides justification for the protagonist's unusual knowledge or abilities, while the action focus ensures regular combat sequences. Japanese versions typically include more character interaction and humor between fights than Chinese equivalents. These 17 balance both elements according to reader feedback.

Kumo Desu ga, Nani ka?
4.4
(1.9K ratings)
Genre: action, adventure, comedy
The world where the Hero and the Demon King continue to oppose each other. The grand magic from the Hero and the Demon King cross over worlds and exploded in the classroom of a certain high school.
First Impressions
"Kumo Desu ga, Nani ka?" is a web novel that took me on quite the ride. It's a reincarnation story with a twist, throwing our protagonist into the body of a spider monster in a deadly labyrinth. While the initial premise might sound familiar, the execution is anything but typical. Initially, I was hooked by the unique perspective of a spider navigating a dangerous world. The early chapters focus heavily on survival, grinding, and skill acquisition. Some might find this part slow-paced, and even repetitive, but I found it quite entertaining, especially with the main character's internal monolog...

To Be a Power in the Shadows! (WN)
4.4
(1.6K ratings)
Genre: action, adventure, comedy
Just like how everyone adores heroes in their childhood, a certain boy adored those who hid in the shadows. One day, after living the mediocre life of a side character while undergoing frenzied training by night, he reincarnates in a different world and gains ultimate power.
First Impressions
I dove into "To Be a Power in the Shadows!" with a healthy dose of curiosity, and I've come out the other side with quite a few thoughts. This web novel is definitely... something. It's a wild ride that blends action, comedy, and fantasy in a way that's both incredibly entertaining and, at times, utterly baffling. Initially, I was hooked by the premise. The idea of a protagonist who's convinced he's living out a chuunibyou fantasy, only for it to actually be real, is comedy gold. The early chapters had me laughing out loud. It's a unique twist on the isekai genre, and I appreciated the author'...

4.3
(1.2K ratings)
Genre: action, adventure, comedy
Liam Sera Banfield is a reincarnator. He had reincarnated into a fantasy world of magic and swords, but at the time the civilization had already been making advancements into outer space.
First Impressions
"I’m the Evil Lord of an Intergalactic Empire!" is a web novel that certainly sparks a range of opinions, and after diving in, I can see why. It's a blend of sci-fi, fantasy, and comedy, centered around a protagonist who's trying to be evil but hilariously failing at every turn. Whether that sounds appealing or not will likely determine your enjoyment. Initially, I was intrigued by the premise. A reincarnation story where the MC aims to be an evil overlord in a space-faring society? Sign me up! The early chapters set the stage, introducing us to Liam and the circumstances of his new life.

EDITORS CHOICE
Apotheosis of a Demon – A Monster Evolution Story
4.5
(798 ratings)
Genre: action, adventure, drama
A back-to-basics(? ) monster evolution novel.
First Impressions
"Apotheosis of a Demon – A Monster Evolution Story" promised a unique take on the isekai genre, and after diving in, I can say it mostly delivers, though not without a few stumbles along the way. The story follows Shedy's journey from abused human to demon goddess, and it's a wild ride. I was immediately drawn in by the premise. A protagonist who isn't afraid to get her hands dirty and doesn't bother with "righteous" justifications? Sign me up! The initial chapters are compelling, and I found myself eager to see how Shedy would navigate this new, dangerous world....

EDITORS CHOICE
Otome Game no Heroine de Saikyou Survival (LN)
4.5
(414 ratings)
Genre: action, adventure, fantasy
A girl Alicia lived as an orphan in a world of sword and magic Ciel. One day, she learned that she was an “otome game’s heroine”.
First Impressions
"Otome Game no Heroine de Saikyou Survival" certainly grabbed my attention with its intriguing premise. We're thrown into a world that initially feels like a typical otome game setting, but quickly veers off the beaten path. Alicia, our heroine, isn't interested in romance; her primary focus is survival. I was immediately drawn in by the promise of a protagonist who prioritizes strength and skill over capturing the hearts of potential love interests. What I appreciated most was the subversion of otome game tropes. Instead of the usual focus on romance, we get a hardcore leveling-up story. Alic...

Isekai Tensei Soudouki
4.4
(441 ratings)
Genre: action, adventure, comedy
Baldr Cornelius is the son of a noble of the Mauricia kingdom and inside him also dwell the souls of the avaricious warring states commander Oka Sanai Sadatoshi and animal ear otaku high schooler Oka Masaharu. Follow the journey of these 3 souls in a single body, as they exhibit extraordinary ab...
First Impressions
Isekai Tensei Soudouki is one of those novels that really grabbed my attention with its unique premise. A single body housing three distinct souls? I was definitely intrigued. While it has its share of familiar isekai tropes, it also attempts to carve out its own identity. The initial hook of this story is undeniably strong. I was immediately drawn to the dynamic between the three personalities inhabiting young Bard Cornelius: his original self, a money-obsessed samurai from the Edo period, and a chuunibyou-afflicted modern-day otaku. This trio makes for some genuinely humorous and interesting...

TS Medic’s Battlefield Diary
4.6
(271 ratings)
Genre: action, adult, drama
An ex-pro FPS player (♂) reincarnates in a fantasy world filled with magic… Only to learn that what greeted him was not a scene from one’s dreams, but a muddy battlefield full of bullets flying to and fro! Moreover, he’s now an orphan girl named Touri Noel?!
First Impressions
"TS Medic’s Battlefield Diary" isn't just another web novel; it's an experience. It’s the kind of story that grabs you by the throat and refuses to let go, leaving you emotionally drained but utterly satisfied. It's a dark, tragic war story with a fantasy twist, and while it might not be for the faint of heart, it's undeniably powerful. Going in, I was wary. The "gender bender" tag almost made me turn away, but the overwhelmingly positive reviews piqued my curiosity. I'm glad I took the plunge. The initial chapters set the stage for a grim world, and while the main character, Touri, starts off...

Tensei Shitara Slime Datta Ken (WN)
4.2
(1.5K ratings)
Genre: action, adventure, comedy
A man is stabbed by a robber on the run after pushing his coworker and his coworker’s new fiance out of the way. As he lays dying, bleeding on the ground, he hears a voice.
First Impressions
Tensei Shitara Slime Datta Ken, or Slime Isekai as it's often called, is a web novel that I dove into with a good deal of anticipation, given its popularity and numerous adaptations. Overall, I found it to be a mixed bag, with some truly enjoyable elements weighed down by some frustrating shortcomings. The initial premise – a salaryman reincarnated as a slime – is undeniably intriguing. The early chapters are engaging, and I was quickly drawn into Rimuru's efforts to build a life and community in this new world. The idea of a slime, of all things, becoming a powerful leader and nation-builder ...

Clearing an Isekai with the Zero-Believers Goddess – The Weakest Mage among the Classmates (WN)
4.2
(1.2K ratings)
Genre: action, adventure, comedy
Makoto Takatsuki is a normal high school student and a hardcore RPG player. However, “normal” goes out the window when his whole class is involved in a bus crash and whisked away to another world!
First Impressions
This title is a mouthful, but after diving in, I found a surprisingly enjoyable isekai story. It's not without its flaws, but overall, it's a refreshing take on a well-trodden genre. Initially, I was wary. Another weak-to-strong isekai? I've read my fair share. However, what immediately grabbed me was the lack of the usual isekai tropes. The MC isn't bullied or abandoned, and his classmates don't suddenly become enemies. Instead, there's a sense of normalcy, which is a welcome change. He's weak, yes, but he's also not a complete idiot, and that already puts it ahead of some others....

I Reincarnated as a Noble Girl Villainess But Why Did It Turn Out This Way? (WN)
4.2
(684 ratings)
Genre: action, adventure, drama
Eliza Kaldia, who reincarnated as a noble girl villainess in a fantasy otome game, was stuck in a world that seemed far from her image of how noble girls should be living, as the fated events of the game were still far off while she remained a child. In the first place, it was suspected if she c...
First Impressions
This web novel is quite the surprise! The title suggests a lighthearted villainess story, but it quickly subverts those expectations. What I found instead was a complex narrative focused on military strategy, political intrigue, and the psychological impact of trauma on a young protagonist. It's definitely not your typical fluffy otome game reincarnation. Initially, I was thrown off by the rapid pace and the dark subject matter introduced so early on. The protagonist, Eliza, makes some shocking decisions in her early childhood, and it takes a while to adjust to the bleak tone. However, I was i...
