Everyone suddenly receives an invitation from Reborn to attend a Vongola-style Maman Appreciation Day party. Reborn is holding this event to entertain Nana, who is always taking care of everyone. But with a name that includes “Vongola-style,” it can't be normal. At the party, Nana selects a winner by giving points to people who reveal their secret talents. The chances that the winner's wish will be granted is, amazingly, 100 percent! Everyone wants their wish granted, and the Sawada family living room becomes a place for serious battle with greed swirling all around.
