The Empty Box and Zeroth Maria #3

Plot

Can you do what it takes to survive?

This time, Kazuki and Maria find themselves trapped in a game of deception and betrayal with four other students from their school. Despite being pitted against each other, the two once again work together in an effort to break the Box's hold. But as the stakes rise and the game grows increasingly twisted, it becomes clear that this is no ordinary wish-and that the owner may be impossible to convince. What kind of person could have created such a Box...?
