Angel contemplated for a moment and attempted to activate the green patterns in his right eye.
When the phantom mask appeared around his right eye, a "Domain Field" constructed by countless dancing green patterns heavily enveloped Angel.
This 'Domain Field' ability, ever since Angel developed it, has established remarkable achievements in areas influenced by the Nightmare Realm.
For instance, when Culori initially stole the Nightmare Light from the Nightmare Realm, he couldn't handle it after his research, so he used a Magical Energy Array to confine it in a secret room within the ruins. The Nightmare Light, which even Culori found troublesome, could easily be isolated by Angel's Domain Field.
Furthermore, the Domain Field can isolate the dome of Eternal Night City, blocking all the maddening murmurs.
Therefore, when Angel felt he might be influenced by some will of the Nightmare Realm, his first choice was the Domain Field.
