What if the Emperor of Mankind was in The Promised Neverland?

The Great Escape

After the tracking devices on Isabella Krone Norman Emma & Ray are broken, they tell Van Helsing of their original escape plan.

Van Helsing: That is a brilliant plan children. Your mother has raised you well. So are the rest of the children prepared to escape?

Norman: Well not yet. There's some things to work out.

Isabella: Sir I forgot to say. If our devices are broken, headquarters will be alerted & send security!
Van Helsing: That's fine, my allies are ready to ambush whoever arrives.
Isabella: Really?!
Van Helsing: Yes, they are eager to test out our new weapons on these demons.
Isabella: Good to hear.
Krone: Oh my, I hope you're not just pulling our leg.
Van Helsing: I'm not, now can you ready the children for the escape?
Krone: Of course, I'm on my way.

The protagonists head to the bedrooms to help the children pack up.
Van Helsing waits by the main door.

Isabella: Alright the kids are almost ready. It's gonna be tough saying goodbye to the place, so many memories.
Van Helsing: I understand. But the human world will become an Imperium of such magnificence it will make this place look like a little hovel.

Then there is a scary bang on the door!

Isabella yells for Van Helsing & the children to hide, a look of visible fear on her face. He obliges, taking cover around the corner like a kid playing hide & seek.

The demon guards break down the door.

"Isabella! Come on out!" Yells the main demon, with his shelled face & vertical eyes.
His larger musclebound guards with similar faces sit outside.

She steps into the living room, scared & shaking.

Isabella: Yes sir, I'm here. Is everything alright?
Demon officer: Your devices have broken, as have the sensors on the stock. Headquarters suspects treachery. (VA Keith Silverstein)

The demon officer steps in, as his guards are too large to fit in the door.

Demon officer: Now where is the mother in training?

Krone: I I'm here sir. The children are all in bed as is scheduled.

Demon officer: At first we were searching the forest for an intruder seen on camera. A strange man not in service of the Ratri family.
Then the alarms went off, we were told that both your mother chips & stock trackers went offline.

Down the hall, Ray Norman & Emma have their backpacks on ready to go. They watch the scene playing out, hearing the voices of the demons they saw in the barn.

Isabella: Its um, I don't know exactly. I did feel a shock in my neck but I didn't know the chip had broken. Krone reported the same thing.

Demon officer: Why didn't you answer the call from grandmother? Something treacherous is going on, & you know the price for that.

Krone: When my mother chip gave me a shock, the kids said they felt the same thing in their ears. It's the strangest thing, we've been having electrical problems tonight.

Demon officer: You lie, now you must come to the office, you have some questions to answer.

Van Helsing: I am the one responsible. Lay a disgusting hand on Isabella & you will suffer. (He says as he stands in sight)

Demon: You! You are the intruder we've been looking for. You unlocked the gate from the outside, but how?

Van Helsing: Just a magic trick. Now you will pay for every child of the Imperium you've feasted upon.
