Meet an assassin’s worst nightmare… POP! X. POP! X, also known as “Slur,” is on the hunt to take down JAA, the Japanese Association of Assassins. Wearing a stylish white trenchcoat, ribbed white turtleneck, gray slacks, and white shoes, his swagger can’t be denied. Don’t let his white hair or many personalities fool you. If POP! X is coming your way, hopefully Sakamoto is by your side, or be sure to cross the street before he reaches your Sakamoto Days collection.
