Every single year, Meia dreads one day - her birthday, when the crew attempts to surprise her with a party. Meia has managed to run away every single year, but this year, Hibiki is here, and he decides to help out the women. Shaking up the plans the women use every year, Hibiki's scouting cuts off every possible escape route for Meia. But when Meia decides to go to Magno with her complaints, Hibiki and the others have to find the perfect thing to keep Meia busy until they can plan the party - even if it happens to be a certain newborn baby.
