Even though they weren't a perfect match at first, this time it changed. Even though their hearts still hate and stare at each other cynically, in a situation like this, working together is not wrong.
Ashnard and Reinhard had thought about the possibility that would happen, and working together was their decision. Even though this was the first time they were in sync, they were able to quickly follow the tempo and flow to the point of cornering Arlon.
They are fast and don't have any instructions when they want to launch an attack. There was no signal. Sometimes Ashnard would attack first or Reinhard would advance. Their ego still persists in thinking of their own attack and own defense.
Moreover, Reinhard was still seriously injured but was still able to follow Ashnard like a healthy person. He can run, dodge or attack quite well.
"You seem troubled, don't you? Back off. Leave me alone," said Ashnard mocking the injured Reinhard.
