I’ve finally gotten through most of the hitman Reborn manga so now the Vongola will get there share of fights. Tsuna and Rock Lee are both hard core hand to hand combat fighters. Except Rock Lee is at a major disadvantage. If he and Tsuna punch each other Rock Lee will either get frozen or burned. Rock Lee has the 8 gates but Tsuna has the famed X Burner. Tsuna wins.
