Today's post is about the birthday events from the game Project Diva F 2nd. In the game Project Diva F 2nd, each of the six Vocaloids have a birthday event. The event can be triggered by going to a Vocaloid's room on their birthday, or giving them their birthday cake. All of the Vocaloids have different birthday events, except for Rin and Len Kagamine who share a birthday event. When the birthday events are unlocked, they have a special border that says "Secret" instead of "normal" when they're viewed in the events list.
