Kyokugen Dasshutsu 9-jikan 9-nin 9 no Tobira: Alterna

Finished

極限脱出 9時間9人9の扉 オルタナ

Junpei is abducted and wakes up aboard a sinking cruise liner that resembles the RMS Titanic. He is not alone: eight other strangers are trapped with him, each wearing a numbered bracelet. They are forced to participate in the "Nonary Game," a deadly challenge where they must explore the ship and solve escape-the-room puzzles to survive. Small bombs implanted in their stomachs will detonate if they disobey the rules.

With only nine hours before the ship sinks, the group must work together to find a way out. But trust is scarce, and the motives of the other participants remain unclear. As Junpei delves deeper into the ship's mysteries, he begins to uncover the truth behind their abduction and the sinister purpose of the game.
