During and school trip, the bus of the 2nd year class 3 with 32 people was summoned to another world... we were gonna be sold to become pilots of robot like magical weapons, but it looks like the values of the selling prices were decided by the values of some unknown parameter called Ludia (ルーディア)... While some classmates got high prices with parameters of 10,000 or 20,000, my parameters were actually 2... really unbelievable... but actually my parameter's value made the measuring machine's needle perform a full turn but no one noticed it... Though I had the strongest parameters... nobody bought me and was actually exchanged as an slave for two fruits.
