What are you going to do when you pass through another world?

Yalin(MC): Perhaps, many of those seniors who passed through another world would like to use violence to solve their problems, but I like to control the fate of a country with economics and races with faith, I use benefits to instigate others so that I profit, and even making them take risk for me without them even knowing. In each country the highest is the king and behind the king is a string that is attach to my hand, for I am their puppeteer.

Yalin(MC): Certainly the credit does not only belong to me, I must give my thanks to the great knights and their leader Zero(Code Geass).
