Museigen no Seikatsu (Unlimited Life)

Sometimes, videogames can be dangerous, especially when your dad makes a system that allows you access to powers from your game. When a malicious game creator uses an update to kill government officials for powerful loot, it takes the gaming system's son and his friends to stop the killers from destroying Japan's political structure. Killing the terrorists will earn them even better loot, but they'll be up against the Top 10. Will they be able to save Japan from another political catastrophe?
