Revelations @end of the world

I summoned Alpha, my only Malevolent Slave who rushed to and targeted Lord of Greed. However, despite his powerful claws, the Anti-Saint was immune to the Malevolent Slave's attacks.

"Where did you get a Malevolent Slave?" Lord of Greed asked me.

"I got them from the Dark Angel trials", I told him.

"So, you are the new Dark Angel?" he asked me.

"I was but I failed the trial in the end", I told him.

"Sometimes success is built upon failures. You will not command this Malevolent Slave if the soul of the Dark angel does not permit it", Lord of Greed told me, but I don't understand him.

"But you should all die here today except the rat", Lord of Greed added and told us.
