Charles was both Alex and Renard's friend.
In fact, Charles might even be the very first friend Renard had made since he started opening up to people.
This was why they were both very angry when their friend tried to kill his girlfriend without hesitation under the influence of the Synchronization Rate.
After all, they knew how much Charles loved Nessia and vice versa.
For the Synchronization Rate to do something so evil as using Charles to kill his own lover was unforgivable.
It went beyond their bottom line.
The first exchange was enough for Alex and Renard to understand that the current Charles was very strong.
So strong that the two of them combined wouldn't be enough to beat him.
Fortunately, they were not the only ones fighting.
As both of them charged toward their opponent, Latifa, Evangeline, Vaan, and Fran also charged in different directions, encircling the dark knight at the center.
