Kael was looking forward to the duel between Kiona and the blue ogre since he felt there wasn't much difference between the two of them power-wise.
Yes, he didn't think Kiona was any weaker than a C-Rank Ogre. He had trained with her and was confident that she could defeat an average C-Rank Beast.
Now, the only question was whether this Ogre was average or among the better ones.
However, just as the duel started, he frowned and looked up into the sky, where he could feel a powerful presence approaching them rapidly.
"He's here," Rias commented casually. "I guess we won't be able to see her full strength today."
Kael nodded and said, "If he attacks Kiona…"
Before he could even finish, she added, "Then he's dead."
Kael smiled and didn't say anything more.
Just as the two warriors were about to clash, something crashed between them, raising dust and ashes, but it only took a second for everything to return to normal.
