As a author you should know the do’s and dont’s in novels. One of the biggest taboo is Nerfing. Author your novel is not perfect and no one expects it to be. After all we all understand you are a novice writer trying your best. There are many other problems your novel has short chapter, dragging story, writing 2 para of previous chapters in current one etc. But to be honest although it’s annoying it’s not much big of a deal. Because your story is good. Even though the filler arc of when he went in past was boring but still people are ok with it. Because we know you will eventually come in line. But now this. I know you mentioned that he is not using his full power. But this is Nerfing at its worst. You need to realize that the Mangekyo Sharingan Sasuke is not even in top 10 when it comes to power level. And now you are making such a character give Kirito such a hard time. This past few chapters are the worst you have written so far. Period. My suggestion to you is simple. If you want people to know that your Mc is holding back. Make sure you clearly line out his power levels. Eg in DBZ they have super Sayan levels, in one piece they have gears. So if you want to have a good fight make sure you let people know that Mc has yet not used Conquerors Haki, Yet not used 9 tails etc. because from this chapter although you tried to mention it. It was not enough details.
After the first half of the fox, where the author had the mc keep complaining about how others were not behaving like ninjas and how you should never give your enemy a chance to reach his best like a vegeta, you had kirito do the exact same. The second he saw sasuke, kirito should have killed him and taken his eyes and wood dna and used it on himself and naruto. With obito and even itachi and madara as future enemies, it ncreasing his and his brother’s power as much as possible was logical. And nsteqd, he is acting like a kishimoto to keep the fights even.
