Alongside the remaining army of Monomis, Chiaki is confined in a closed room. Monokuma comes in, riding in a tank. He then starts to shoot them, reminiscent of the game Space Invaders. However, Chiaki quickly spots an exit and swiftly escapes from the room, taking a Monomi with her, while the other Monomis follow them.

Monokuma chases them down in his tank, similar to Pac-Man, trampling several Monomis in the process until there is only one remaining Monomi - the one Chiaki carried.

Afterwards, Chiaki enters another room, only to find out that there is a glass wall that prevents them from continuing. With the shutter behind them closing, they are trapped inside the small gap. Several Tetris blocks start to come down, eventually crushing Chiaki and the last Monomi. Once all the Tetris blocks in the last couple of rows are perfectly lined up, it then explodes.
