Into The Darkness

Isadora looked at the thin red line on her palm. A drop of blood was dripping down, its warmth and stickiness confirming over and over that it was real.

If it's because he's blessed by the World Will Of Hortus as its Lord, it's understandable. But she stayed in the ruins for the precise reason she didn't want to risk fighting Lord of A World, even more so, Lord of a unique world like Hortus.

'And yet, he continues to defy expectations. As if reaching rank 4 wasn't enough, he's manage to injure me, no matter how small. This man is too dangerous.' Isadora narrowed her eyes, peering through the smoke.
