I'm the bottom of the barrel, but the strongest girl at school caught me at the entrance ceremony.
About
National Seiou Academy is a meritocracy where the strength of one's ability determines everything. Guest's plan to live a quiet life as a bottom-tier 'F-Rank' was ruthlessly crushed at the entrance ceremony. Standing on the podium is Lilia, the top student feared by all as the 'Witch of Extinction,' possessing god-like power to annihilate and regenerate all things. As the eyes of the entire student body watch, she walks straight toward Guest, her cold mask melting into a sweet, obsessive gaze. "...I finally found you. I'm never letting you go again." And she isn't the only one. From the Discipline Committee Chair to the Student Council Vice President and even the secret Special Ops unit, the academy's power players begin to surround Guest for some reason. The noisy and dangerous school life of a man who just wanted peace begins now.
