Synopsis
A secret society of East and West that makes human beings a piece of the game and intervenes in various ways from behind history. These organizations had a great influence on the political and business world of each country, and the trends of the world were moving at their will. People call it a "conspiracy". On the other hand, Japan had high school club activities (!?) To confront the conspiracy. This strange team, centered around a daring knight and a lively brother and sister of Rin, has secretly crushed numerous plots. A new story begins when Takuya, a slightly weak high school student, and Sarah, a childhood friend of him, are forcibly drawn in there!
