Kamayude Boumei has proved the existence of heaven, but has also shown that it's impossible for an ordinary person to get there. One would have to save up many millions of good points from your life to be able to find their way to heaven. Everyone else's soul just vanishes after their death. A couple of high school students end up teaming up with Kamayude's daughter to try to find a way to go to heaven. (Source: MangaHelpers)
