Coin Locker Baby (if you get this reference,then good job!)
Chance is trapped in a airtight container by Monokuma. He is then put into SCP-119,a time warping microwave. Monokuma sets the timer for one minute,and starts the microwave. For what is a minute for us,it's hours upon hours for Chance. He starts to get hungry....thirsty....and it gets harder and harder to breathe,until all he's breathing in is CO2. Chance had suffocated by thr time Monokuma pulls him out,smiling at the crowd watching.
