Robin relies on Angel's Lifeline (costs 2 Angel Power)

Just as Robin was ready to submit herself to whatever punishment awaited her for losing the game, she and the audience both started in surprise as a white glow surrounded her lower body and the sound of angel trumpets came from somewhere overhead. In a burst of light, her nethers were suddenly covered once again, this time in a frilly white bottom decorated with winding gold embroidery. "It's... underwear?!" she gasped.

"Another favor from our Lord. This will give you one more chance for victory! It isn't much, but I hope it will bring you some comfort."

"Actually, they're hella comfortable," Robin admitted, testing out the stretch of the waistband. "Thanks, Colline!" She turned her attention back to the opponent and placed one hand on her hip. "Now... how about one more round? If you think your luck will hold out, that is!"
