Gakuen Dragon Slayer

An entire school is suddenly ripped from its ordinary reality and thrust into a war-torn fantasy realm locked in a desperate conflict against dragons. Stranded in this dangerous new world, every student and staff member within the building is presented with a formidable weapon: a powerful sword specifically forged for slaying dragons. The terms of their survival are made abundantly clear by the inhabitants of this realm. There is only one path back to their original world, and it requires them to actively participate in the ongoing war and help secure victory against the draconic threat. However, wielding these extraordinary weapons comes with a highly unusual and restrictive condition. The swords possess immense power, but they can only be activated and utilized by individuals who have maintained their virginity. This unexpected prerequisite instantly transforms the student body's social dynamics and personal histories into matters of life and death. Those who meet the strict criteria must step forward as humanity’s unlikely champions, while those who do not are left powerless in a hostile world. Caught between a brutal war and an embarrassing requirement, the students must navigate both the battlefield and their own personal circumstances if they ever hope to return home.
