Volume 1:-
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?!

Volume 2:-
After over a decade spent searching for the truth, Ange has sifted through every slander and scandal hurled against her family as an explanation for their murders. What she cannot accept are her brother’s saccharine versions of the people and events she has been so desperate to know. Her rejection, spurred on by Bernkastel, begins to rip apart Battler’s game board at the seams, and the happy reunion of pawns quickly becomes a battle of life or death!

Volume 3:-
Though none may know the truth about what happened the day of the Rokkenjima massacre, Ange has come to understand the players were neither devils nor angels, merely people—her flawed, complicated, ultimately loving family. Now battling against every kind of cruel theory that’s been leveled at the Ushiromiyas since the tragedy, those who remain in the cat box fight to preserve the memory of their humanity. Armed with this truth, Ange strides forth to reclaim her future!
