Shadow Slave

Grasped in the Shadow's fist was a strange, beautiful, and ominous gem. It was utterly black, as though suffused with impenetrable darkness. The glossy black surface seemed to devour light, turning the vast hall of the ruined cathedral even darker than it had been before.

Deep within that black void, crimson flames burned with a menacing red glow. It was pulsating in a slow and bizarre rhythm, drowning everything around in dim red light. Painted by it, the Stone Saint seemed to be drenched in blood. The gem she held looked like a bloody, still-beating heart that she had torn out of someone's chest.

Gazing at it, Sunny felt a strange sense of foreboding.

'What the hell is this thing?'

The gem looked sort of like a soul shard, but… different. He had never seen a black shard, to begin with, or one radiating such an intense glow. It also didn't seem like a piece of a broken core. On the contrary, it appeared… whole?

'Is that what a soul core of a Nightmare Creature looks like?'

No, not a soul core.

A soul?

Stunned, Sunny counted the crimson flames burning in the depths of the black gem. One, two, three… four.

Four flames for the four cores of Fallen Devil.

The thing that his Shadow held in her hand was the Black Knight's soul… or some sort of his essence, at least. By how had it turned into a material form?

Did the Stone Saint do it? If so, how… no, why?

'What is she doing with it?!'

As Sunny and Nephis looked in stunned silence, the Shadow finally moved. Bringing the black gem close to her face, she lingered for a moment. A hint of a dark, macabre emotion appeared in her eyes.

And then, the Stone Saint… swallowed it.

Sunny blinked.
