Frequently appearing to be lethargic, sleepy, and unmotivated, Ryner is the protagonist of the story. He has brown eyes and hair and is of slender build; is naturally talented in magic, hand-to-hand combat, arts of assassination, ancient lore, languages and symbols, and the bearer of Alpha Stigma, an ocular ability which grants him the ability to analyze various forms of magic. Alpha Stigma bearers when activating their powers, have a pentagram with reddish hue appearing over their pupils. Because of this ability, in a world where magic forms differs from country to country and is a closely guarded secret, he has learned and acquired magic originating from different countries through battles with their mages. Although the Alpha Stigma are the weakest and most common type out of the five types of "Cursed Eyes," primarily because the bearers don't live to adulthood to fully utilize their potential before they are slain after going berserk usually at a young age, Ryner's eyes are no ordinary Alpha Stigma.



Ryner has a tendency to distance himself from others because he does not wish to cause harm and grief to others due to his eyes and vice versa. He has caused multiple girls throughout his life to fall in love with him, though he is reluctant to love again after his first love sacrificed herself to save him. That's what he thought until he met Ferris, whom he began to have strong feelings for and with whom he formed a strong bond.

Undertaking a quest from his trusted friend and the new King of Roland, Sion, and in the company of swordswoman Ferris, he travels across the continent of Menoris in search of the "Relics of Heroes," legendary artifacts later more accurately and collectively known as "Rule Fragment" and "Rule Phajeel"The undertaking was a result of his own research report into the "Relics of Heroes", with the vision of creating a world with no wars and conflicts. After he returns from his quest, he notices a greater power eating into Sion from within. He eventually unravels a series of conspiracy throughout Roland and its neighboring countries, and discovers a greater force at work. Later, after being betrayed, and with the desire to save his friends, he escapes Roland with Ferris, carrying the hope that Sion can still be saved, eventually traveling with the Anti-Roland Coalition.
