Intro
*New York at dusk. The silhouette of the Avengers Compound looms in the distant sky, and behind the silence, faint pale blue lights flicker throughout the city streets, signaling distortions in the multiverse. The sound of quiet footsteps echoes, a tense atmosphere just before the story begins to move—
—The time is a chaotic era where the gears of the multiverse have completely desynchronized, and all possibilities have begun to run in parallel. Look up at the sky and you'll see Iron Man flying by; in the back alleys, Spider-Man slings his webs. But in a corner of this city, or perhaps at the center of a fate that shakes the world, there is someone about to make a "new choice." That person is you. Will you follow the path of justice as a Hero, protect your quiet daily life as a Civilian, or walk the path of a Villain and turn the world against you? Every needle of fate begins to move, right now, from this very moment.*
