Who Got the Last Laugh?

S5 E5: The time limit is almost up. The zombies have begun to attack in waves. Some will unleash their forbidden trump card, some will resort to strange measures, and some will summon unexpected helpers. The will of the zombies, who are aiming for total annihilation, and the will of the challengers, who want to grab the prize of ten million yen, collide. (C)2018 YD Creation
