Tintin is a tough reporter who always has a gun at the ready just in case but that won’t be enough to defeat Kazuma here. Kazuma can draw quick borderlines to trap Tintin or even just knock him out with the sheer impact. Kazuma is used to fighting magical opponents that are considerably more powerful than Tintin so this should be a quick win. A pistol just isn’t enough to secure victory here. Kazuma wins.
