Angel perceived anomalous emotions in the Gray Merchant, and actually, he had already begun to gradually reduce the use of Hyper Perception. After all, Hyper Perception, much like a Supercomputer, requires a considerable amount of computational power, which is a huge burden on Angel's mental capacity.
However, Angel could not be entirely sure that the anomalous emotions on the Gray Merchant were coming from "her."
So, to be cautious, he only weakened his emotional perception of known sources, remaining highly vigilant about unknown sources.
Because of this, when anomalous emotions came from the void, he was able to detect it immediately.
The so-called "anomaly" actually means "different from the rest."
What's the dominant emotional tone in the void? Malice, slaughter, bloodthirstiness, cruelty.
What contradicts the main theme, being "different from the rest," is naturally benevolence.
