Special Admission, the Principal Said I Was an S-Class Disaster

I'm just a strong high school student who unexpectedly became a special admissions student at Prometheus Academy. The whole school spread the word that I was a "humanoid disaster". The principal poured me tea with a smile, and the school board of directors held a meeting overnight to "dispose of me harmlessly." The student union offered a reward of 100 credits to the whole school to pursue him. The senior sister cried and begged me not to cause her to go bankrupt. Even the 3A exam gave me an unprecedented "Threshold" grade. I just want to do three things about this: Survive, get stronger, and figure out what is going on with Threshold and that brickworm in your pocket that's always chewing on strange things. They said I was an uncontrolled monster, a walking "doorkey." But I don't know that in my eyes, those indescribable horrors, intricate conspiracies, and the academy itself... They are all problems that can be calculated risk, cost-effective, and ultimately "solved".
