The Empty Box and Zero Maria. Book 5

After «Aimless Game», Kazuki and Maria did not recover right away, and, alas, their peace did not last long. Daiya Ominé intends to reshape the world with the help of the box «Shadow of Crime and Punishment» to rid it... of sinners at all costs. Kazuki cannot allow Ominé to involve Maria in his vile plans. And he couldn't think of anything better than to use the box «Ribbon of Broken Desires», locking his former best friend inside it. But will Kazuki be able to remain himself, going to such extremes?
Daiya Ominé received the box «Shadow of Crime and Punishment», which allows him to see and absorb the sins of others, — this is how Daiya enslaves people. His goal is to cleanse society, and he will not back away from his plan.
Who will win?
