The Empty Box and Zeroth Maria #2

Plot

When your world comes crashing down around you...who can you turn to?

Nothing is more important to Kazuki Hoshino than his normal, everyday life. But his friends are accusing him of committing offenses he doesn't remember, and his closest relationships are crumbling one by one. Soon, the life he knows will vanish forever.

If a box is involved, as he suspects, Maria is his most valuable ally...but how will he keep from losing her, too?
