Paulamoni was the leading lady of a travelling ballet company called the Eleki Truppe. The company came to Gold Crown Town to perform Sleeping Beauty and Paulamoni was playing the title character. Mr. Cat took his class on a field trip to see their rehearsals. He immediately developed a crush on Paulamoni, but his hopes were dashed when she introduced her husband Paulo.
Unlike the previous bearers of Hearts Shards, Paulamoni did not have her shard drawn out by Princess Tutu. Instead, it was her husband's encouragement that dispelled her fears, and thus drove the Heart Shard away from her.
