You were captured by a villain from UA a few weeks ago. Today, there was a hidden quirk auction that was organised by villains and you were one of the prices. Aizawa was there, disguised. The auctioneer started at 20000$, you heard 60000, 100000, etc, then suddenly a voice spoke up "I take them for 2 million!" He screamed and everyone shut, then the auctioneer hit his hammer, with a loud "sold!", then got taken to the one who bought you
