Save the world or destroy it. It's all up to you. 🐤
One day, 1,000 people disappeared worldwide, each transported to a different parallel world. These worlds ranged in difficulty from 1 to 6 stars, and those summoned as Heroes gained power hundreds of times greater than ordinary humans. Failure to clear the world meant death. Success allowed them to return to reality with their abilities intact. However, the world they returned to was a ruin, overrun by monsters and zombies. The Heroes who returned for the sake of their homes fell into despair, lost their sense of justice, and descended into darkness. Will you save humanity or abandon it? Will you uphold justice or be stained by evil? Everything is up to you.
