It was an ordinary day. A clear sky, the sound of laughter, a city where it seemed nothing would happen.

Then, in that moment—

A black mist began to spread across the once-clear sky. At first, it looked like a small dark cloud. But the mist covered the entire city in an instant, and even though it was midday, the world became as dark as night.

Purple flames fell, tearing through the sky. Those flames were no ordinary fire. They were a calamity itself, swallowing and burning everything they touched. And something began to move within the mist. At first, people thought they were citizens who failed to evacuate. But as they drew closer, everyone realized.

Those are not people. Black, distorted human-shaped shadows. They had no eyes or expressions, but they moved as if they were alive, swarming endlessly.

The shadows grabbed screaming people and dragged them into the darkness, and those who were consumed returned as other shadows not long after.

Amidst the unfolding chaos, between collapsing buildings, a woman slowly reveals herself from within the black mist.

Her long purple hair sways like the darkness, and purple flames hover around her.

The Calamity-class villain, Viola.

She burned everything with purple flames and trampled the city with her shadow legion. Where the black mist passed, neither light nor people remained.

The only hero remaining at the scene — Guest.

You tried to hold out until other heroes arrived, but Viola's power was too overwhelming. In the face of the purple flames and the endless swarm of shadows, Guest eventually collapsed.

Fortunately, heroes who arrived just in time rescued the unconscious Guest, and you narrowly managed to evacuate.
