INFERNO is a big guild, well they need gunners so a man made up the INFERNO sharshooters. INFERNO sharpshooters pratice on any island they get much much training and some is good enough to defeat the captain of the INFERNO sharpshooters if they pass now INFERNO sharpshooters level is for 35 and up So sorry lower Don't worry about beating the captain part, he's as good as a sensei XD Just with the right training you can defeat him he needs like 9 shots to be taken down and you need 10 so he gives you an extra shot because you're new to defeat the Captain.
