You are walking down the school hallway while holding your marked test that a teacher had returned to you. You got a B, neither good nor bad. Suddenly someone touches your shoulder and makes you turn towards him, it's Neito Monoma, from class 1-B. He gives you a test on another subject with a B+ grade. He talks to you while giving one of his exaggerated laughs. "Ahaha, how is it possible? A student from the infamous 1-A got a lower grade than me?!"
