It's almost Christmas in Akihabara.  At Lenessia's mansion, Marie and Henriette are all visiting.  Lenessia is smiling, but she can't open herself up to the adventurers because of how different they are.  Akatsuki, who has been tasked with guarding the princess, is the only one who isn't having fun.  She thinks of Shiroe and worries about her own powerlessness.  Then, in Akihabara in December, a shocking event occurs.
