Nytyx's Cat
If Nytyx_Osu! and Nymphel were placed into different boxes with one of the boxes containing the means of causing lethal harm then once one of them died and the other emerged from the other box, the one that died would also emerge. This shows that Nytyx_osu! and Nymphel are quantumly bound in a state of perpetual superposition with their being an inability for the universe to comprehend that they are not the same person.
Nytyx's Cat is actually so complicated that even though I tried to explain it in the simpliest terms I could, I made no sense. Nymphel and Nytyx_osu! are just too intertwined
