Five of me? (A Crossover)

Krist and Singto find themselves greeted with a bizarre poster. They didn't know it would lead to being locked in a room with their other selves from different universes. But they don't know of this fact. They didn't know this at all.

This is a crossover featuring Krist and Singto's characters. What will happen when they all meet?
