Kierana was still struggling to break through Antoinette's barrier and was getting agitated by that situation, based on her frantic whining in her Bloodhowl form.
Antoinette then held up her hand and blasted Kierana away with her Dark Mana, which Kierana was able to land on a pillar and howl menacingly, which gave everyone who heard it a sense of intense blood-chilling fear, hence the name of her form.
After Kierana howled, she looked at Antoinette and leaped towards her with her snout opened, baring her sharp teeth.
Antoinette then closed her eyes and immediately turned away from Kierana's attempt to grab her with her teeth, and continued to evade her attacks flawlessly.
This got the crowd excited and many were cheering Antoinette on, with Vincent holding his necklace anxiously for his half-sister.
Antoinette was still dodging attack and attack and this aggravated Kierana much more.
