プリズム・アーク ～プリズム・ハート エピソード２～

Princia, the heroine of the previous game, has now become queen. Despite any action she could now take as a ruler, the seeds of war have already been sewn. Strife will return to the land, but still her own daughter (and the new heroine), Priecia, aspires to be a great fighter like her mother was. Despite the seriousness of her training and the battles soon approaching; she will still have her fellow students and friends to help lighten up the epic mood of the story. You play as another student at the same academy, and together you will face your destinies.
