As Seth and Grokus confronted each other, so did the others. Nero crossed swords with Rainer. As a God whose essence revolved around swords, cutting and sharpness, there were very few that could match up to his expertise in swordplay on his level.
Rainer's talents also lied in swordplay, but it did not solely revolve around this concept. That was why he did not blindly try to beat Nero with his swords. Instead, he utilized his extensive knowledge of spells and techniques to try and one-up Nero.
"Tch!" Nero clicked his teeth in irritation as Rainer once again slipped through a spatial tear that the latter had used his swords to create. The leader of the Nameless Order appeared behind Nero and was about to slash down when his senses screamed at him, prompting him to hurriedly jump away and put some distance between the two of them.
CRACK!
