Reborn as Upper Rank One

The author truly respects the original work; the character development is incredibly smooth and well-done. Of all the transmigration stories I've read, this author's is the best. The others either have flawed character development or create harems, which is nauseating. Only this author's work is truly enjoyable and leaves a lasting impression. I eagerly await updates every day! 😘

This is the best Demon Slayer novel I've read so far. I first saw one where the protagonist was Kokushibo, so I clicked to read it, but by the end I found out he was involved with Muzan, which made me want to explode. Then I found this novel, and so far there haven't been any out-of-character moments. It's very well-written, and every time I finish a chapter, I want to read it again.

I used to not ship Japanese/Japanese characters, but after reading this book, I really enjoyed it. Their interactions are so sweet, and every time the main character changes forms and encounters Yoriichi, I get a special feeling of excitement (especially when he's in women's clothing).

I've been reading for so long and I forgot to give it five stars, my apologies! The protagonist, Iwakatsu, has a really interesting personality; his inner monologues are genuinely fun and I love reading them, especially his cowardly behavior towards Yoriichi and his (tu cao, a Chinese internet slang term for sarcastic or witty remarks) about his scumbag boss. It's really entertaining. Great read! Author, keep up the good work with updates!

It's seriously, seriously amazing! I have a question: how did the author manage to include official pairings while also writing the ambiguous, antagonistic relationship so well, without anyone criticizing it? The comments section is full of different opinions, and the language is quite rough. Surprisingly, no one is blaming me. It feels like I've entered paradise. Everyone around me is so friendly. This book is truly, truly amazing! ❤️❤️❤️💕

This is a pretty good book. The romance is well-developed. Although the plot is basically the same as the original, some parts are quite interesting. The protagonist isn't particularly afraid of his younger brother, so I suggest giving him a role where he can be the strongest man's woman if he can't be the strongest man in his normal life—that would make him invincible! 😏

Holy crap, this is amazing! I stayed up until 5 AM to finish it. I absolutely love this story! The descriptions of Yoriichi and Kokushibo are so wonderful, I love it so much! Wow, I dare say this is the best Demon Slayer I've ever read! There are other good ones, but they all have flaws. Every word and every sentence in this one is captivating.

It's absolutely gorgeous! It's a real gem among Tomatoes, so smooth and beautiful. 🥰

This is simply a masterpiece!!! It's been such a long, long time since I've seen such satisfying fanfiction!!! It's not melodramatic or mindless, it's logical, and the characters are exactly as I imagined them!!! The writing is excellent, it's super, super, super, super good!!!

It's great! From the beginning, I had a feeling that the brother was the only one... Jin Guangyu's feelings for the brother and the brother's feelings for Yuyu are like a two-way street! I'm not good at writing book reviews, but it's really good. Occasionally, I felt that the author was too lenient with the brother. He's such a good friend (?). If he had taken countermeasures earlier, things wouldn't have turned out like this, hahaha. Otherwise, I think it's well written.
