Moegi is a very sweet and noble young woman. She harbors much interest in Western societies and is very welcoming to Vyse's crew when the latter first landed in Yafutoma, serving as their primary caretaker during their stay in the guesthouse next to the palace. Though she appears fragile, she has a very strong will much like Fina and will not hesitate to stand up for herself. In the game's end sequence, she marries Enrique and becomes the Empress of Valua.
Enrique falls in love with her upon first sight and is the only one to note that the princess appears to be hiding some struggle she's not so keen on sharing (later revealed as the issue of marrying Muraji) and she falls for him not long thereafter. After Vyse and his friends helps drive the Valuans out of Yafutoma and banish Kangan and Muraji, the emperor of Yafutoma and Daigo agrees to let Moegi go with Vyse's crew, and she joins the crew as a delegate.
When used in a ship battle, Moegi blocks all magic damage to the Delphinus for one turn; this ability costs 10 SP to use. If included in the Active Crew during the Blue Rogues special attack, Moegi heal the group surrounded by bubbles.
