When Momoka becomes infected by an unknown virus, the government's fearsome and secret National Survival Game Club moves to restrain her. Miou announces the Survival Game Club's mission to throw a birthday party for Urara! While Momoka is normally cold to Urara, she decides she should at least be nice to her on this day and does her best to prepare.
Because it's the same day as Christmas, 
she's never celebrated it properly.
Weil er am selben Tag wie Weihnachten ist, 
hat sie ihn nie richtig gefeiert.
Ya que nació en Navidad, nunca 
celebran su cumpleaños como se debe.
Ya que nació en Navidad, nunca 
celebran su cumpleaños como se debe.
Por ser no mesmo dia do Natal,
ela nunca o celebrou direito.
