Yoshiki Tonogai: 19 books

All rise for the final verdict... With everyone playing it close to the chest, the courthouse is teeming with murderous intent. Lives are cut down, one after another, until the final four remain. At long last, the bell to signify the end of the game rings out. Will those left standing truly be able to make it out of this place alive?

It's time to clear the docket. Who could possibly be responsible for this game? That question swirls among the participants, who grow more desperate as they are forced to make one horrific choice after another. The game is to conclude when the requisite four survivors have been determined....

When one of the students is attacked after his sins are brought to light, the remaining survivors grow ever more suspicious of each other. As secrets arise and suspects collide, the question remains: If one murderer truly was hiding in their midst, are there really two more watching from within?

"There are three murderers hiding in your midst." These ominous words given to the six survivors of a tragic bus accident are followed by an ultimatum: The murderers must anguish over their crimes and find a way to answer for them within one week, or the evidence of their sins...

The tension among the survivors of the bus accident reaches its threshold as the one-week deadline finally arrives. The three killers may have confessed, but does this mean that all their sins are accounted for? What truly constitutes a crime? Or to what extent is an action criminal? When the gavel falls on their sentences, perhaps all might not be as it seems.
