"What is going on?!"
Nero Chaos's formerly cold, rigid expression had twisted into something almost theatrical, like a clown performing onstage.
But that was only natural.
Anyone who had been lost in the ecstasy of turning certain defeat into victory one second, only to hear tragic background music ringing in their ears the next, would have looked like that, if not worse.
Although Nero Chaos, an ancient and traditional mage, knew nothing about the death flag of a woman singing while a man died, that did not stop him from realizing how serious this was.
Because the moment he realized he could not identify the source of the song, he had physically destroyed his own hearing to avoid falling into a trap.
Yet even so, the song lingering in his ears had never disappeared.
"Aaaaaaaaaa..."
It was a song filled with profound love, more alluring than a siren's voice, yet chilling to the bone.
Merely listening to it brought a freezing chill, as though both body and soul had been frozen stiff.
"Damn you, what did you do to me?!"
Staring at Roland, who seemed to have lost interest, Nero let out an unrestrained roar.
Mental erosion of this degree meant nothing to someone who had discarded even his personality, but this uncontrollable unknown still awakened the unease he had forcibly suppressed with his obsession.
"Nothing."
Roland shrugged.
"Didn't I tell you? You're killing yourself."
"Absurd!"
That casual attitude enraged the vampire once again.
He raised his claw, preparing to swipe toward Roland.
Of course, Nero did not believe his attack would work on Roland-in fact, after reviving, he had already decided to flee the city immediately if Roland made any unusual move.
He had achieved his ideal system tree anyway, so the White-Winged Duke's mission no longer mattered to
