The People of the Motherland Are in the Reincarnation Space

My name is John, and more people call me - a native of the motherland. I was stabbed through the brain with a crowbar, and then entered a place called "Reincarnation Space". There is only a cold mission and a line of words: "Everything you want is here." My first mission is: destroy Konoha. Great, I'm good at killing people. I'm dead. The first trial, the mission failed. This is the story of a giant baby, a monster, and the most popular superhero in the United States, who is forced to learn how to become a "hero" in the reincarnation space.
