{On the other side}
"Then let me remind you again who I am."
-SHUSH!
Xalvar released his mana aura displaying his Viscount strength. The Rank-B Devil Contractor and other Devil Contractors trembled in fear. For them, the Devil was god themselves and they could not help but tremble when Xlavar displayed a power that they could never attain.
However, it was a different story for Zero. He brandished his sword and prepared his magic bracelet. He already got used to Rank-A pressure when fighting with Professor Mia.
Moreover, with dark Energy, he could exert the power of Rank-A. Therefore, even when Xalvar released his Rank-A mana aura, Zero was calm.
!!
Xalvar was surprised and also dissatisfied with Zero's lack of expression. He was planning to have Zero tremble and beg in front of him.
-WHOOSH!
Xalvar quickly disappeared and appeared behind Zero. It was not that Xalvar had teleported but because he was fast, it seemed like he had teleported.
-CLANK!
