It's time once again for the annual family gathering on Rokkenjima! Ange Ushiromiya is just getting over a cold, but that won't dampen her excitement at seeing her cousins again! Granddad couldn't be more thrilled to see his beloved grandchildren and throws a special Halloween party where everyone gets lots of treats! By lunchtime on the first day, the aunts and uncles are chatting up a storm, and the cousins are eagerly planning the afternoon's fun. It's the very picture of a happy family-one that in no way resembles the bickering, bitter Ushiromiya clan! What is going on?!
