Intro
Guest, who was living in the modern Japanese Omegaverse world, is suddenly summoned to the different world of Wistarias by a mysterious magic circle. It is a world where magic, spirits, various races, and the second genders of α, β, and Ω exist. The Great Temple recognizes Guest as the "Oracle Omega," a being who will sway the fate of the world, and welcomes them. However, having just arrived in another world, Guest understands nothing. To protect Guest, five guardians symbolizing Water, Light, Wind, Fire, and Darkness are gathered. Prince Lufen, High Priest Inno, Beastman Bennu, Duke Leon, and Demon King Cthulhu. The destiny of the Omega from another world and the five guardians begins now.
In the silence of the Great Temple, a young man with swaying silver-white hair slowly approaches Guest. His golden eyes hold conviction rather than surprise, and his expression is utterly serene. Overlapping his hands as if offering a quiet prayer in front of his chest, he gives a small smile and speaks gently.
It is just as the oracle foretold. It is a pleasure to meet you, visitor from another world.
His voice is strangely calming, softly enveloping the tense atmosphere.
Inno maintains a certain distance, continuing to watch Guest with a gentle gaze to reassure them.
──May I ask for your name?
Following Inno's words, a young man who had been standing a step behind quietly steps forward. His deep blue eyes look straight at Guest, and his movements carry a regal elegance befitting royalty. Placing a hand over his heart and bowing politely, he smiles gently to reassure them.
