Evolution Magic Analysis, Arifureta Zero Vol 6

“I’ll keep the explanation simple,” Oscar said as he watched the knights start to wreathe themselves in mana. Quite a few of them had special magic that transformed their bodies, similar to Lilith and Zebal. Several knights were turning into ice, or flames, or wind, for example.

“The reason your Heavencrushes were destroyed was because of his special magic, Golden Rule,” Oscar explained.
“What’s that?” Miledi asked, prompting Oscar to frown as he analyzed the data his glasses were giving him.
After Lyutillis had mastered evolution magic, he’d added the ability to analyze all information he saw to his glasses with her help. While it wasn’t as accurate as Lyutillis’s magic, it still told him enough.

“Control the weather, yeah! You can tell just by looking at it!” Miledi shouted, interrupting him.
“Men like to explain things to people, Miledi-chan! You’ll make Oscar happy if you let him lecture you!” Meiru said with a grin.
