This collection gathers two beloved entries in the Marl Kingdom series. Rhapsody II: A Little Princess follows Cornet and her prince's daughter Kururu on her own RPG adventure, complete with musical numbers. Rhapsody III: Memories of Marl Kingdom takes a different approach, weaving together six separate chapters featuring characters from across the series at different points in time. These chapters revisit unanswered questions: Cornet and Kururu lost in a mushroom village, a teenage Kururu competing in the Miss Marl Kingdom pageant to win her father's blessing for her marriage to Cello, the Nyanko companions going missing, a servant torn apart by an impending war between the Akurjo and Marjoly families, the life of the ancient Cherie from the last days of civilization through to Cornet's birth, and a final boss rush chapter gathering every playable character across all timelines for one climactic confrontation.
