27th December, Living Room (with Hatsune Miku, KAITO, MEIKO and Megurine Luka)... The Kagamine siblings barge into the room, shouting,

"EVERYONEEEEEEEE!"

The other people in the room look at Rin and Len, slightly annoyed by their loud noise. However, the twins look happy, shouting once again,

"It's our birthday!!!"

Miku, Luka, MEIKO and KAITO exchange glances; it is clear that they have forgotten such a big event. Rin notices their expressions and says, pouting,

"Don't tell me you all forgot again..."
