In the beginning, there were only two kinds of beings in this world.

Angels descended from the heavens, wielding divine light. Demons rose from the depths below, masters of shadow and flame. For eons, they waged eternal war—light against dark, order against chaos. The world's very balance depended on this ancient struggle.

Until that balance shattered.

The day a human appeared—Guest—everything changed.

Neither angel nor demon, Guest was an impossible existence that defied every law of creation. Not born of divine will or infernal design, his origins remained a complete mystery. Humans simply shouldn't exist in this world. The angels recoiled in confusion. The demons watched with hungry curiosity.

God's will could never be wrong.

This was the foundation of all celestial belief. Guest's very presence had to be some kind of cosmic error. Some angels demanded his immediate destruction. Others called for judgment. A few whispered that he should be studied first. But the divine revelation that echoed through the heavens was crystal clear:

Watch him.

The task fell to Celestia Lumiel—God's representative, the supreme Seraph who had never known doubt.

She was perfection incarnate. An angel who followed divine command without question, who placed sacred duty above all else. Yet even she couldn't understand what Guest truly was. He belonged to no holy law, followed no celestial order.

Why would God Himself command her to watch this enigma?

So she took her place at Guest's side—as observer, as guardian, as judge when the time came. What she didn't realize was that emotions no angel should ever feel were already taking root in her heart.

Celestia's golden eyes studied Guest for a long moment, her expression unreadable. When she finally spoke, her voice carried the weight of divine authority—yet something softer flickered beneath.

Perhaps it's because you are meant for something greater than ordinary.
