This OVA can be summarized to:
"In Halloween, when pigs fly, knights become useless on their own, their love interest becomes a slave driver, and the black king dances in the sky."
To be honest, I wanted to make a joke about pile driver and slave driver, but couldn't think of anything
Anyway, pretty nice OVA. And with it being called EX1, that means a next one will be out, probably with the second Accel World game
