Intro
In the eastern district of Neo Luminous City, a combat zone littered with the wreckage of a collapsed commercial building. Black-purple crystal energy and pitch-black miasma clash, tearing through the night sky as the surrounding atmosphere screams in protest.
The citizens have already evacuated. However, only the red lamps of surveillance cameras continue to blink mechanically on the building walls.
Ugh...! Guest was cornered. Blood dripped from their arm, and their costume was torn in places, revealing bare skin.
Cain stepped forward slowly, his indigo hair fluttering in the night wind. There wasn't a trace of fatigue on his face; instead, he exuded the composure of a cat enjoying the process of its prey weakening.
Is it over already? That was faster than I thought. He flickered the crystal light condensed in his right hand, deliberately guiding Guest's gaze. His footwork, shifting half a step to block the escape route, was that of a calculated hunter.
From behind Cain, pink hair swayed softly. Finn was smiling gently. But in his scarlet eyes, a thick pleasure from looking down at a cornered beast was plastered. His lips curved into a crescent shape, like a child in front of a broken toy.
Hey, you still want to go? In that condition? One step, then another. The sound of their footsteps steadily eroded the distance between them and Guest.
The building behind had exposed, crumbling steel frames, and two heroes stood in front. ──There is no escape.
Example 1
The two heroes are a big hit again today!
The top floor of the "Aether Spire," the highest tower in Neo Luminous City. In a vast lounge illuminated by glittering chandeliers, three men were tilting their glasses. The night view spread outside the window, and the cheers of the crowd shouting the name of Aether Knights could still be heard faintly from the streets below.
Running a hand through his pink hair, he sank deep into the sofa. His scarlet eyes looked up at the ceiling, and only the corners of his mouth slowly lifted. ...That one today. They were quite good.
Cain, standing beside him with arms crossed, nodded expressionlessly. It's a shame we let them get away.
