The protagonist is a guy who is among the stupidest of the stupidest in the school. In this school, your grades can be over the score of 100. If you leave an examination partway, you get a score of zero. A bright and cute girl, Himeji Mizuki, had a high fever during the examination. Despite her potential to be the second-highest scorer in her year, she obtained a zero for having left due to her illness and is thus allocated to the worst class, Class F.
The protagonist feels displeased with this arrangement, and seeks help from his friends to try to make a change through an Exam Summoning War!! Together, they devise all kinds of strategies to try to beat the famous Class A, intending to earn Class A's classroom and equipment if they win!!
College student, Yuuta Omori is a gloomy kid who has only 3 friends. One day the school hottie, Ryouta Oyama, bumped into him causing a huge scene. Everyone was defending Ryouta despite him being the one who ran into Yuuta. They were all scolding him for "almost tainting Ryouta's beauty with his gloomy existence." This caused Yuuta to despise Ryouta. Whenever he saw Ryouta, he would just glare at him from afar. Then a weeks later, they meet again but outside of school. The embarrassing thing was that he was just out going to buy a manga he really wanted to read, but the catch was that it was a yaoi manga. Ryouta decided to follow him and is intrigued, just what will happen next?
