FTHTD-113 ZOMBIE HIGH SCHOOL COMPLETE EDITION

One day, a big earthquake hit a peaceful school. When we woke up, the world had turned upside down… An unknown FT virus had spread throughout the school, turning everyone into zombies. Apparently, those of us who hadn’t turned into zombies had some immunity, and Dr. Takashima developed a vaccine from our sperm! Drinking it increases our sexual energy! It seems that ejaculating inside will reverse the zombie effect. We rose up to save our friends!
