Masatake followed them as Kuro started to talk and ask them if they came prepared or if they should stop and buy supplies and one of their teammates who is called Fukusho at least Masatake thinks that's his name asked the same question and Masatake slowly opened his wrists and needles came out of a small compartment in one of his sleeves now his hand had 4 needles between his fingers and Masatake showed them to both of them "this is all I need. If we need anything else then ill assume ill get them after this is done with" Masatake said before he raised his hand up and the needles went back down his sleeve hiding themselves in the process. A needle user relies on a few things one is the element of surprise since a needle can easily be a concealed weapon in a skilled persons hand, the second is that someone will underestimate the effectiveness of said needles as they don't inspire much intimidation considering their not as large as a sword, and finally they need to be in the hands of someone who can use them to their full effectiveness which was Masatake. Masatake simply kept walking and didn't stop as he started to lead the group forward believing that if they were going to do a combat exercise then the needles were all Masatake needed
