the fight between hisoka and kastro was one of my favorite battles in hxh. hisoka used tricky techniques to defeat kastro, pretending to be unable to defend himself from kastro’s attacks, while actually trying to get a better understanding of his techniques and nen category.

i really liked when hisoka distracted kastro by talking about how nen categories affect a person's personality. while he was doing this, he quickly attached the bangee gum to kastro, and it ended up playing to his advantage in the end.

another interesting moment was when hisoka made it seem like his severed arm had miraculously reattached, but in reality, it was a napkin infused with his aura. not only did hisoka defeat kastro with his abilities, he quickly noticed how self-assured kastro was and decided to undermine his confidence by stating that he had easily figured out his ability weakness. kastro tried to compose himself, but it was the final blow when hisoka described how kastro would die.

i remember when i watched the next episode about hisoka’s abilities, i couldn't fully grasp how they worked. this battle was truly genius
