Dame-Tsuna Welcome to HunterxHunter

Tsuna has just turned 18 and his hitman tutor discovered a Hunter world that could be a perfect Spartan training get away for his student, with a few helps from his trusty gun, our poor Tsuna-fish is sent out into this place full of Hunters. So Tsuna set off to take the hunters exam, mentally pulling his hair and what can be worse? Getting stuck in a 12 year old body, thats what.
