Behind the Scenes in Tokyo: Controlling Japan and Sparking a Great War

No System + ensemble cast style + not a one-man show + stirring things up from behind the scenes + extremely cautious The story is a slow burn. The protagonist grows stronger over time, takes control of the island nation by manipulating events from behind the scenes, then launches a major war. In a parallel world with supernatural powers, transmigrator Zuo Tengming goes to study in the island nation and awakens supernatural abilities. Finding life among the locals incredibly boring, he establishes the Shadow Assassin Alliance and sets the beautiful scenery ablaze, from the island nation all the way to the United States. The main plot follows his behind-the-scenes supernatural scheming.
