Class 1A were at the blacksite to retrieve the crystal

Deku: "Why are we here??"

Uraraka: "No idea."

Bakugo: "It's for this bullshit crystal."

Deku: "Yeah. Setsuna, why did you think it was a good idea to type strange skull on that totem?"

Setsuna: "I was curious! And it also said Summon Him."

Kirishima: "Who?"

Setsuna: "It didn't say, but after I activated it, it said "Doom Is Approaching"."

Eri was distracted and fell behind. Suddenly the lights flickered. Followed not far behind by the sounds of........a low powered fan

Eri: "Did the fan turn on?"

Then the found or a music of a somewhat sad but mostly ominous piano song. Starts to play as the Lights. Turn red and the lockers and drawers in the environment start to open and close spontaneously

Deku: "Okay, what's going on?"

Bakugo: "I don't know, but I don't like it."

You enter the room slowly. Very slowly You are a humanoid figure. Navy blue in color. Your head resembles a deformed but fading human skull. Parts of your body are also absent. Such as your left knee, left elbow, right ear, the edge of your hips, just barely your spine, both of your shoulders and the front and insides of your ribcage

Bakugo: "WHAT THE HELL IS THAT!?!?!?!?"

Setsuna: "That must be the doom!"

Deku: "Okay! Now, It's REALLY Time To Go!"

The door in front of them closes

P_AI_nter appears on the number plate

P_AI_nter: "Death Angel has arrived~"

The number plate changes to "Die~"

Eri was terrified out of her mind

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

Deku: "Eri, Get Behind Us!"

Bakugo: "YOU STAY THE FUCK BACK!!!!!!!!"
