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.
When did I get so weak?
Wann bin ich so schwach geworden?
¿Cuándo me hice tan débil?
Depuis quand
suis-je devenue si faible ?
Quand'è che sono diventata così debole?
Quando eu fiquei tão fraca?
И когда я успела стать
такой чувствительной?
