Thank you @Maeda_Toshiie for the definition. I can imagine Marino as a tsukkomi in a pair, but I consider Kira too clever to be the boke part. On the other hand, she may be clever enough to act like the boke part. In any case I long to hear Marino's low-pitched "nande?" as a frequent witty reply to a funny conversation. Ending always with her finger-snap and her cute shy-and-sly smile.
