God Is in the Last Row of the Classroom

He is the supreme leader of the decent organization "Tribunal" and has stood at the pinnacle of human force at the age of sixteen. In order to protect a city where an ancient evil god was sealed, he disguised himself as an ordinary high school student and sat in the last row of the classroom. The villain organization "Twilight Church" has launched a super war around the world, closing in on the city step by step. They didn't know that the "head of the Tribunal" they were looking for was being punished by the math teacher for copying his homework.
