Yoona didn't reject this setting, because she knew that Lichte would be much more competent than the usual testers. They weren't the type of people to go easy on things like this because they had pride in their own power.

First, Aria chose Reina as her opponent.
"Choosing me... Huh? I wonder what went inside your head in order for you to make this decision?" Reina chuckled as she accepted the offer and stepped into the fight podium with Aria.
