Uluru's Ability

Uluru drew a gun from behind her back, and right before the enemy could make contact, she yelled, “Get down and close your eyes! Otherwise, you’ll die!”

Fal was startled. He wasn’t equipped with the functionality to get down or close his eyes. Keek, who had modified Fal, had been emotional when it came to magical girls, but she’d been extremely pragmatic when it came to mascot characters. She’d modified Fal heavily many times, but she’d never given him any humanlike functionality.

And those choices Keek had made meant Fal would die here. He could not get down on the ground or close his eyes. And since he couldn’t, he was going to die.

The three Shufflins dived headfirst onto the ground. Snow White and Sorami threw themselves to the ground, too, but then quickly stood up again.

Snow White was so calm, it was as if she couldn’t even hear what Uluru had said. She took the rope Sorami had tossed her, then tied up the arms and legs of one of the Shufflins on the ground, and Sorami and Uluru joined in. The Shufflins were still on their stomachs with their eyes closed. There was no sign at all that Snow White, Uluru, or Sorami were going to die.

Then Fal remembered. There was no reason they would die if they didn’t get on the ground and close their eyes.

Uluru’s power to “make people believe her lies” had caused the Shufflins to believe her claim that “If you don’t get down and cover your eyes, you’ll die.” They’d thrown themselves down on the spot and closed their eyes. With the card soldiers left helpless, Snow White, Uluru, and Sorami had tied them up. Uluru’s magic immediately came undone once the victim realized she was lying, as it did with Snow White, who had heard Uluru think, I’ll be in trouble if they find out that’s a lie. It had also quickly come undone for Sorami, who knew how Uluru’s magic worked. Fal, meanwhile, had listened to an explanation of her magic earlier and remained confused for only a little while. Only the three Shufflins, who had not known of Uluru’s magic, continued to be caught up in it. Inside Snow White’s bag, they were still prostrate with their eyes closed.
