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.
But we had a big event planned...
Und wir wollten ja ein Event veranstalten.
Teníamos un gran evento planeado.
C’est dommage,
on avait prévu une fête.
E dire che avevamo preparato un grande evento...
Tínhamos um evento tão grande planejado...
А мы ведь подготовили ивент...
