In the unique educational institution capable of granting superpowers to individuals, the Senei Academy, there is a student named Yuto Amemori. Due to certain reasons, he wants to lead an inconspicuous school life. However, his superpower, the ability to “impair vision,” is pathetically weak. This power triggers the protective instincts of his classmate, a beautiful girl aiming to be a superhero, Kasumi Asahina. As a result, Kasumi insists on protecting him, saying, “I’ll protect you!” And this leads to an unwanted relationship between the two. Yuto becomes a target for delinquent students who dislike this situation. But the truth is, Yuto hides his true abilities to appear as an ordinary person. In reality, he possesses the most potent superpower since before his enrollment. Secretly, Yuto starts plotting to eliminate obstacles, involving Kasumi in his schemes. This is the tale of a monstrous entity pretending to be powerless, scheming behind the scenes to dominate the school. The story begins!
