I'm in a Crossover World, Starting with Becoming Invincible in Demon Slayer

!? Even the official couple is being fought over? I really don't understand, why the sudden shift to suggestive content? Sorry, I really can't watch anymore (crying) (utterly shocked)

He has too many abilities, many of which are rarely used, but there are almost no flaws; it's a typical wish-fulfillment story.

Infinitely weaken the fighting power of the Hokage

Ugh... The pacing is so fast... It feels like I've only watched a few minutes and the plot is already halfway through...

Why not call him Isshin Ashina? (Laughs)

It's not very good. It feels quite jarring. A few extra scenes can add some reading interest, but there's just too much of it. I felt awkward reading it. While the Demon Slayer Corps members are dedicated to killing demons, doesn't anyone suspect the protagonist, who's a suspicious individual? He even seems to have precognitive abilities from time to time.

The author, who writes fanfiction, seems unfamiliar with the original anime and manga. They were completely baffled by the mention of "Sense Haki," only realizing after reading other reviews that it was a misspelling of "Observation Haki." Similar errors abound. Many characters' personalities and behaviors have also been distorted by the author, losing the original flavor and unique charm. Overall, this book is only mediocre.

It's alright. The author writes in a rather casual style.

It's pretty good, I support you! Author, please don't abandon the story halfway through!

The novel is a mess of couple pairings; not only does the protagonist himself engage in this, but even characters from the original work use modern internet slang. Having read so many novels, this is the first time I've felt compelled to write a review. I dropped it after reading less than 30 chapters.
