What should I do if I wake up and see my gender-swapped self?

The answer is "fight" (meaning to get into a fight)!

(After some probing) It turns out they weren't enemies after all. I was just 'scaring myself'.

Shore Guard: "How come there are two 'Ah Piao' (CPU crashes)?"

Remnant Star Society: "We dare not open our eyes, hoping it's just an illusion..."

Mingshiki: "666! I was so scared I cried!"
