While wandering around the train station in search of the enemy team, Noah noticed through his Pyakugan something passing at high speed. If it weren't for this skill, he wouldn't even have noticed the muffled noise of that person's careful steps passing him.
'Hmm ... so their assassin is proactive,' Noah thought as he went on to follow the invisible assassin.
In practice games they noticed two types of assassinations from the other teams. He has come across proactive-type assassins, like this assassin he just encountered, who would actively try to go after the enemy team to kill the weakest members faster, as much as he found more reactive assassins, who were ambushing and waiting the enemy, leaves a gap so that they can attack and kill as much as possible, based on the enemy's standards.
