Master and disciple relationship 

Ares, Daisy, and Rebecca stayed together for that whole afternoon. Since they were hanging out and Ares was new on Goliath, both women decided to show him the place. Actually, it was more Daisy's initiative than Rebecca's. The latter didn't seem to care about these things.

The more Ares witnessed Rebecca's coldness and frivolity, the more it stood out compared to how she was when battling against him. She looked like a different person, especially when their battle was approaching its final stages.

However, the redheaded boy decided to just brush off the matter. He just preferred to consider her some kind fight addicted soldier. It would be easier to deal with her like that. 

For some reason, she did not have any empathy for anyone, but mainly Ares. From time to time, she made it clear that she was dissatisfied with the result of their duel and wanted a rematch.
