Liberate

"The bastard has escaped," Rai confirmed as he sucked back all the hell-fire back into its body and revealed himself.

It is really good at escaping; first, it had escaped from the lady Vivian, and now, it had escaped from you," I said, looking at the spot from which it had disappeared.

I am very regretful; not only we have let a very powerful Grimm Monster escape, but I also lost a source of great boost. If I had harnessed its bloodline, then there would have been very few High Grandmasters that would have posed a threat to me.

Barely anyone would have had the power to break my shields; even Rai wouldn't have been able to break my shields, even if he used all its strength or even burned his whole bloodline, that strong of the boost it would have given me.
