After the family's succession trial puts Princess Leticia's corrupt brother, Prince Tyros, as the new heir to the throne. Leticia is forced to act. Traveling in disguise, she heads to the dangerous port city of Zeven, to face her destiny.

In the kingdom of Aleister, every prince and princess must explore the Sea God's Shrine to prove their worthiness for the throne. Only the one who explores its deepest depths can come to the heir. The lazy, sleazy Prince Tyros has set a new record, beating all his siblings, and the only way to stop him from becoming king is for Princess Leticia to go even further. Will she be able to conquer the shrine unscathed?
