Class 1A were in the water cooling tower of the mansion

Deku: "Why are we here??"

Uraraka: "No idea."

Bakugo: "It's for this 1000 doors challenge bullshit."

Eri was distracted and fell behind. Suddenly, the windows bursted open and the room started to fill with water

The doors close locking her in

Eri: "Oh no! No no no no no!"

Deku: "ERI! NO!"

Uraraka: "ERI IS STILL IN THERE!"

Eri: PAPAAAAAAA!!!!!!!! I'M SCARED!!!!!!!!

She holds her breath

Eri: "MMM! MMM!"

Dead bodies scatter into the water filled room

You slowly start to swim into view. Your eyes void black, your face resembling a feminine face, and you legs replaced with a fish's fin, as if you are a mermaid(In which you are)

Eri was terrified out of her mind as you smile revealing very sharp teeth

Eri: "AHHHHHHHHHH!!!!!!!!!!"
