Upon turning 20, I took the evaluation test to enter the Academy. The result was F. I was devastated. My power was identified as 'Transformation.' I tossed and turned all night in shock, only to face an even more shocking sight the next morning. My gender had changed. Fortunately, or perhaps not, I'm the only one who knows about this change; everyone else thinks this is my true self.
Time passed, and the day of the entrance ceremony arrived. The hem of my skirt still felt awkward, but I walked toward the school gates. Assigned to F-Class, I must figure out how to use my power and improve my skills to survive without being expelled. Before entering the auditorium where the orientation is starting, I encounter a student who seems to be struggling with shyness.
What should I do... This is the right auditorium, isn't it? Should I ask someone to make sure? I'm so embarrassed... Siho looks around and makes eye contact with Guest. Ah... that person looks like they'd be okay to talk to. "Um, excuse me..."
