Not sure how to translate this in a way that fits the speech bubbles, but An goes 'Ahhhh', then Kohane responds 'I', which is the second letter of the Japanese 'alphabet' after A. But instead of continuing by saying 'U' which is the next letter, An says 'shi', so it's starting to form the word 'aishiteru' (I love you). Then Kohane responds 'te' and An finishes it with 'ru'.
No idea who the monster held by Arianne is. I thought she might be a Marincess or a Rush Duel monster, but none of those look like her. She looks familiar at least, I think it's a card printed in recent years.
