Zero was woken up by his heartbeat. The heartbeat was not his, but it was exactly the same as his.
He walked through a door that appeared out of thin air and came to the City of Mirrors. Purple sky, mirrored ground, skewed buildings. There are already six people waiting for him in the city - a madman hugging a cat, a cold-faced woman who reads minds, an old man holding a thermos cup, an intelligence dealer drinking milk tea, a ridiculously strong bricklayer, and a killer who says "I'm here to kill you."
This is a copy game. They are the chosen players. But Zero soon discovered - he was not the chosen one. He was called.
The abyss called to him. He is the abyss.
