Princess Elle and her Golden Knights Penthesila, Margaret and Marry have finally arrived in Atlantis Academy. Although they had hoped for and had expected a swift mobilization of the Academies and the nations of Avalon against the common threat of the Demons, they soon discover that they may not even gain any assistance at all as many are resistant to the possibility that the Demons that had once brought so much fear to them may be at their doorsteps again.
While Ray prepares for the upcoming Trials of Valour, the final examination of the Academies, he receives a mission from the headmaster classified as an S-class mission: to ?guard Princess Elle, show her around and get to know her?. To fulfil his mission as his master requested, Ray brings his royal guests to the most beautiful place in the country ? the Gardens of Atlantis.
