After trying to hold Junko Enoshima back from attacking Monokuma, the floor beneath the both of you opened and you both fell down a dark pit. After waking up you see Junko (who looks different now), and someone who looks oddly familiar naked.

Scenario 1: The both of them

Scenario 2: Mukuro

Scenario 3: Junko (NTR and warning, Mukuro has to watch)

(Everyone is 18+)
