Humorously (and tragically enough only briefly), Ragna in this exchange in Rachel's Chronophantasma gag reel, when Celica admits to having a crush on him:
Celica: "I like Ragna? Of course I like Ragna! You didn't know that?"
Ragna': "Well... I-I didn't think you hated me, but... when you put it so frankly, I... I'm getting embarrassed, here."
