Kafka has only just started his hero adventure and he’s already pretty tough. That’s certainly a good sign for his future when it comes to power levels but I don’t see him being able to do much of anything to Tsuna. Tsuna is incredibly fast and his power is the real deal. He’s been taking down villains for a very long time at this point and has a lot of combat experience. Kafka’s strength and speed don’t even come close so Tsuna can fire off one of his X burners and that will be the end of the match. Tsuna wins.
