Rider
Rider's blush deepened further as the other servant began to open her bag but, before he could fully open it, his master fired a chunk of ice. Rider reflexively summoned up her weapons as she detected the surge of magic but, to her surprise, it headed towards the girl's own servant, knocking the bag towards Rider.
Desummoning her weapons, she gratefully took hold of the bag, accepting the man's apology despite her blush.
"Thank you", she said to the girl, smiling even as she continued to blush.
