On December 29th, Kamijou Touma awakens to find that a mysterious girl named Alice has snuck into his blanket while he was asleep, complicating his already severe problems, in danger of being held back and with extremely limited funds to last the week. Things get worse when while shopping for food on the Delivery Go Round, the prison train Overhunting crashes and surviving prisoners from Operation Handcuffs escape into the city, causing Touma to be tangled up in the operation's aftermath and the lingering effects of Academy City's darkness.
