Late at night, there was a knock on the door of the St. Freya Academy dormitory.

"Who is it?!" Kiana asked, her voice trembling with sleepiness and alertness as she pressed against the door.

A voice brimming with energy and tinged with amusement came from outside the door: "Observer of the long river of history, Pathway to the Throne of Heroes, Listener to the Words of Divine Wisdom, Holder of the Chains of Heaven, Successor of the Sword Saint of Avalon, Successor to the Heroic Savior, Best Collaborator and Funeral Attendant of the Bishop of Destiny, Golden Flash who gallops across the Sea of ​​Quanta..."
