Regarding Ishizaki, he probably hates me more than he hates Kouenji but he's doing his best not to let it show. To be honest, he probably wants to hound me but Ishizaki knows full well what will happen in that case. That rough demeanor of his may resemble Sudou but when it comes to reading the atmosphere, Ishizaki is far superior. I get the impression that he respects his opponents and acknowledges what cannot be denied. That's probably why Ryuuen kept him as his side too. But that doesn't necessarily mean Sudou is inferior to Ishizaki.

Sudou is far superior when it comes to the physical side of things and in all likelihood, Sudou surpasses him in academic ability as well. Since Horikita's guiding him, Sudou will probably continue to develop slowly. Even though they are a similar breed, the weapons each one of them possesses is fundamentally different.
