how did tanjiro become a demon

40 chapters, didn't change significant thing to the original story. on the first travel to the demon slayer, he just replaced and took away the chances of growth for tanjiro, then just vanished in the face of that world leaving them to their doom as tanjiro became weak. back to fairy tail world for nothing to change again just to self insert

I hope Author-san can find a way to solve the Demon Mark that only allows him to live a limited lifespan. Although I am a noob when it comes with Demon Slayer. Just heard about that curse that Tanjiro has. Great read by the way. Please continue.

This is a good fan fiction For me this will be the easy version of demon slayer due to Tanjiro having a big brother but It has a good development, Not Being too OP(Is it?!?)in power rankings of this world solo This is a good story Overall

If Davey was strong enough to kill the demon lord with one slash , then how did he become so weak and lost to a local gang even if he had just one arm .clarify this author, nice read btw

I am going to be honest in this review. I enjoyed reading this fanfic, but that does not mean it is good. The MC, who is a demonic sword, does not act demonic in any meaningful way. You could argue that how he acted when he first met Tanjiro was demonic, but realistically any legendary sword would act that way to test its wielder. For the most part, he has been aiding Tanjiro in everything he does, to the point where it feels like Tanjiro is dependent on the sword. Tanjiro becoming dependent on the sword is another issue. Currently, Tanjiro is portrayed as if he cannot think for himself. The MC (the sword) tells Tanjiro what to do, how to do it, and so on. The MC is not really guiding him, but instead giving him direct answers to every problem that comes up. To me, this version of Tanjiro feels like he is nothing without the sword, which leads into the third issue. The MC (the sword) has the capability to permanently boost Tanjiro’s base strength by 30% every time they kill a demon. This has happened roughly 4–5 times from what I have read. However, I do not know if this is multiplicative or additive. Either way, he should be significantly stronger than before at the very least 150% even high if its multiplicative(271%), yet he is still portrayed as weaker than a Lower Moon who was able to pierce his heart almost instantly. Keep in mind, the MC (the sword) also has the ability to boost Tanjiro by filling his body with demonic energy, giving him a 50–100% increase in strength. This would mean he becomes 1.5–2× stronger during those moments, and yet he is still struggling. Even the original Tanjiro was able to face a Lower Moon who was a candidate for Upper Moon and almost defeat him. Yet this version of Tanjiro, who should theoretically be much stronger, is struggling against a Lower Moon who was basically cannon fodder in the original story that was only given screentime just to be killed. And what makes this feels even worst is that right now he is learning total concentrated breathing earlier than his OG counterpart so that another increase to his total strength compared to his OG who did not know TCB and fought a upper moon candidate This does not make sense. But still, I like it. Even though the power scaling and character portrayal feel inconsistent, the idea of an MC as a sword in a fanfic is new and interesting. Hopefully, as more authors try this concept, better versions of it will come out someday.
