As if he saw through Irisviel’s thoughts, Caster showed an expression of scorn, spat out a laugh as if he was acting in a one-man’s-show, and said:

“… Ah, looks like you still can’t make up your mind. I expected to wait for a long while too, so just take your time making preparations. C’mon, this is such a boring game – can I borrow a corner of your territory?”

Caster clicked his fingers. The children who were obediently following Caster’s back all the time opened up their eyes as if waking up from a dream. The children looked about themselves helplessly, as if they couldn’t figure out where they were.

“Listen children, we’re gonna play hide-and-seek. The rules are simple. Just run away from me. If I catch you – “

Caster’s hand stretched out from the sleeve of the cassock with a swish, and caught a child beside him.

“Stop!”

Saber knew that her prevention would have no effect, yet she couldn’t help but yell out.

The sound of a skull shattering. Brain matter sprayed in all directions and eyeballs slid down in the air. Those nightmarish scenes were engraved into everyone’s mind.

The children let out a harrowing scream and scattered everywhere. Caster, standing in the middle, laughed loudly and happily and licked his blood-covered fingers with his tongue.
