The Lonely Saintess and The Greedy Phoenix

His words were purposely used to upset Sigurd, causing her to grumble while biting her lips. A thin red line oozed down her chin, and she seemed overwhelmed with anger.

She probably understood that if she wanted to crush him with pure power, her true strength would obliterate him.

It wasn't the strength of her body, mind or spirit that would be the most dangerous, but the sword itself. Even though he destroyed that tower and its monsters, he couldn't defeat her, even if he used his phoenix manifestation. 

"You bastard, you say this knowing I cannot fight you with everything!" Like a wail of anger and lamentation, Sigurd's thick voice echoed throughout the training room, filling his ears and soul with her heartfelt sadness and fury.

Her delicate eyes glared at Asura, causing him to know that he should take the next attack seriously, but he doubted her current emotions would allow her to use all her strength.
