After seeing Vincent's confidence, Luna no longer convinced him to change his mind as she allowed him to fight.
In her mind, a direct battle against their "boss" doesn't seem appropriate if his subordinates are still doing fine. They should be battling them first before they could get a chance to fight against Vincent.
Agatha had similar thoughts to this but decided not to voice them out.
Anyway, even though they believe that Vincent should only fight if they were unable to, they would still respect his decision.
It only feels weird for them as it seems like Vincent was protecting them instead of the other way around.
Luna could only shake her head as she returned to her position and stood beside Agatha.
The two remained silent and carefully observed the surroundings.
