I was sold at the lowest price in my class, however my personal parameter is the most powerful

I was the cheapest one in my class, yet my hidden abilities were unmatched. On a school trip, our bus—carrying 32 students from Class 3, Year 2—was suddenly transported to another world. We were meant to be auctioned off as pilots for magical robot weapons, but the prices were determined by a mysterious factor called Ludia (ルーディア). Some of my classmates fetched high bids, with Ludia values reaching 10,000 or even 20,000. Meanwhile, my recorded parameter was a pitiful 2, which seemed impossible. The truth? My actual power was so immense it made the measuring device’s needle spin completely, but no one caught it. Despite having the highest potential, I went unsold and was traded away like worthless goods—exchanged for nothing more than two pieces of fruit.
