Kaguro was a very unique villain. From what I first saw his appearance, he seemed to a sword happy lunatic minion with a flashy style and would be a powerful, but ultimately insignificant look. Once I watched it, Kaguro was very different from my first impression. He was a very mental opponent with a mix of laid-back and invasive behavior that makes for a very out of the box opponent. He is in fact the main focus of this arc and the villains I thought would be the main enemy turn out to be secondary.
+Grimoire666 Yeah, I really liked Kaguro. My only problem with him was that his death seemed very anticlimactic. Such a great villain deserved a better ending.
I agree. Yoshimori really should've taken his advice and decided to learn the black sphere attack of his older brother or spoiler (the blank state- an uber mode for Yoshimori after training) and faced him when he was stronger.
